Conférence : Is quantum randomness a fundamental property or a technological resource?
Thursday 1 july 2021, 13h45 - 14h30 — Amphi Abbé-Grégoire

The randomness of quantum predictions seems absolutely fundamental to avoid the violation of operational relativistic causality. As a result, it offers a unique technological resource in the field of random number generators. This will lead me to answer "both" to the question, leaving the listener to choose among these characteristics, which seem to me to be as fascinating one as the other.

Conférence : Can the coin toss save a robot from harm?
Saturday 3 july 2021, 11h30 - 12h15 — Amphi Paul-Painlevé

Deep learning techniques lead to fundamentally non-interpretable decisions made by the machine. Although such choices do not have an explanation, they impact the users in significant ways. If the ultimate innovator is a machine, what is the meaning of responsible conduct? I argue in a recent book that the capacity to extract an AI system from human judgment, by reducing transparency in favor of opacity, is an essential value in machine ethics. This can be achieved through the use of randomness, illustrated on several examples including the trolley dilemma. Methodologically, a comparison of common motives between technological setups and mythological narratives is used to achieve ethical insights.

Conférence : Is the moment decisive in photography?
Friday 2 july 2021, 11h30 - 12h15 — Amphi Jean-Prouvé

This paper proposes an exploration of the ways in which photography can participate in a better understanding of the multiple — and sometimes contrasting — implications of the notion of « chance ». Taking distance from the phrase « the decisive moment », once used by photographer Henri Cartier-Bresson and subsequently much quoted but rarely contextualized, we will discuss the tension between deliberate choice and accident in several areas: episodes of the invention of photography; photographic practices (capturing images, choosing a specific image from a series of many on a contact sheet); the circulation and cultural uses of one photographic image on a variety of supports and in a variety of contexts. Added to these areas, a reference to Richard Powers’s Three Farmers on Their Way to A Dance (1985) — a novel inspired by a photograph by August Sander — will contribute to fleshing out the main argument of the paper, which emerges from questions such as: the role of agency and chance in the creative process; effects and formal possibilities opened up by accidents; deliberate and accidental choice of images in the construction of cultural representations.

Conférence : Is cellular order based on molecular stochasticity?
Friday 2 july 2021, 10h - 10h45 — Amphi Jean-Prouvé

The living cell is frequently compared to an assembly of tiny molecular machines that functions in a perfectly ordered way. Similarly, cell differentiation, that constitutes the basis of embryonal development also considered as a tightly regulated programmed process. However, the “cell-machine” metaphor is not supported by empirical evidence. At the molecular scale, molecular disorder is dominant in the cell. Traffic and interactions between individual molecules and the resulting chemical transformations are all random. However, given the probabilistic nature of biochemical reactions, how the molecular chaos can give rise to the cellular order? The individual molecular events are random, but they are also very short lived compared to cellular processes. The regular functioning at the structural- and time-scale of the cell is generated by the huge number of high frequency and short-lived molecular interactions. This principle is well known in physics, but it is still new in biology. Thinking of the cell as a manifestation of the principle of “order from disorder” has strong theoretical and practical implications; it allows to get rid of the hidden finalism frequently observed in biology.

Conférence : Can chance be managed?
Thursday 1 july 2021, 10h - 10h45 — Amphi Paul-Painlevé

Today, chance evokes gambling, the search for strong emotions, the lure of winning and even the ultimate feeling of living. Chance is then of the order of the living and the emotion. In management, we don't talk about chance, we talk about risk. Risk is a probability, so it is a rational calculation. More precisely, it is the probability that an event will occur, the consequences of which are feared. Risk management is based on a simple principle: we evaluate the probability that the problem will occur, we quantify the damage it may cause, and we look for solutions that cost less. Risk management has developed in many areas: we can think primarily of production, where we can avoid accidents to people, but we can also manage financial risk or legal and social risks, for example. However, the calculation of probabilities often lags behind what organizations experience. Chance, when it combines events and human actions, is also present in the effects of crisis on organizations; a one-off crisis, or a crisis that lasts according to the evolution and exchanges of living beings. In the face of crises, proven methods of risk management are not suitable, because chance is precisely out of the question. But if chance can provoke crisis, it provokes above all new forms and figures, and for those who are aware of it in time, it can be a source of opportunities, creativity and innovation, which are also outside the field of risk management. Thus, if chance is linked to the game of life and emotion, it is also because it causes a hitherto controllable universe to leave - at least in appearance - through the emergence of another universe in the making and whose rules we do not know. Chance provokes irreversibility, and in this it is opposed to risk management, whose main function is, on the contrary, to maintain the status quo. With the irruption of chance in its management, the organization has to face evolutions that frighten because they change routines and solutions to the established efficiency. Contrary to change projects, chance cannot be controlled or decided upon, it arises by issuing a challenge, and the art lies in anticipating in time the new rules of the game it imposes.

Conférence : Does random organize complex systems?
Friday 2 july 2021, 10h45 - 11h30 — Amphi Jean-Prouvé

The behaviour of Nature at microscopic scales seems to be ruled by probabilistic laws making impossible to know, for instance, what will happen in the collision of two elementary particles. At larger scales, Nature exhibits reproducible phenomena that pushed Humankind to develop a deterministic view of our Universe as it was exhibited in the Newtonian laws of mechanics. Statistical physics give a rational explanation of this apparent paradox by invoking the averaging of local fluctuations producing reproducible phenomena at macroscopic scales. This theoretical framework allows especially to abstract a a view of order generation from local disorder, an interesting point of view to explain diluted gas properties or magnetic properties inside materials. Nevertheless, it does not provide a complete toolbox to address the organisation of complex systems in which emergent properties are being observed while they resist to be simply explained in that framework based on an bottom-up point of view. In this conference, I will address the question of the role played by dynamical constraints that apply on a complex system at various scales in its final structure when this system has a probabilistic dynamics at low scales.

Caroline Granger Caroline Granger
PhD candidate in American studies

Caroline Granger is a Ph.D. student in American Studies at the University of Caen Normandy where she defends a transdisciplinary approach that intertwines human movement and its environment. Her dissertation “Torsions” focuses on American dance in the twentieth century and more especially on Merce Cunningham’s works. In 2019, she received a travel grant for on-site research in New York from the Institut des Amériques to observe the relationships between human beings and their milieu through interviews of dancers and choreographers. This hands-on process, beyond words and pictures, leads her to attend many workshops and participate in artistic projects.

Conférence : What is the nature of chance in dance?
Saturday 3 july 2021, 16h45 - 17h30 — Amphi Jean-Prouvé

The word “chance” is often associated with Merce Cunningham’s creative process but it has not been analyzed through its multiple expressions from the creation stage to performance. Focusing on Rainforest (1968), this conference proposes to study the different manifestations of “chance” throughout the metamorphoses of the piece. This paper proposes to tackle the issue through the study of patterns—testimonies of “chance procedures”— found in the choreographer’s notebooks. Which choices were submitted to the roll of the dice? I shall then discuss the transmission from his personal notes to the dancers’ bodies. How do they live through the movements? Which twists do the dancers accomplish? When time comes for the performance and the sharing of a space, music, visual and choreographic works intertwine. These experimental meetings produce what Robert Rauschenberg calls “accidents”, unexpected situations through which dancers adapt themselves. Does “chance” give birth to improvisation? To conclude, I focus on the spectators’ experiences of the performance through an eco-poetic reading of the poem Rain Forest by Alexandra Grilikhes and wonder if “chance” brings about magic.

Conférence : Does aerobatics leave room for chance?
Saturday 3 july 2021, 9h15 - 10h — Amphi Abbé-Grégoire

Before the pleasure of taking off in an aerobatic plane, I always carry out a thorough checklist: in aviation, nothing can or should be left to chance. Yet many aeronautical innovations are the result of such chance. Since the Montgolfier brothers' aerostat, it has been necessary, it is always necessary to leave room for chance to discover and explore new territories, to allow the emergence and development of aviation. However, the concern to avoid failure and accidents, to control risks by leaving no room for it, has always been at the heart of the concerns of aviation players, from the design of aircraft to the organization of air navigation or knowledge of meteorology. To some, the simple fact of flying in an airplane still seems to be left to the chance of beliefs, of a god or a good fairy who will draw lots for those who have to survive a flight. We are well aware that this is not the case, but that zero risk does not exist in aviation and that we must always be wary of events that may occur by chance, without it being possible to predict or prevent them, in order to reduce as far as possible all sources of possible failures. So, does aerobatics leave room for chance? Sometimes, at least in competition, during the drawing of lots for the order of competitors in a world championship! But once everything has been checked... alea jacta est!

Conférence : Is the relation a constitutive contingency?
Friday 2 july 2021, 12h15 - 13h — Amphi Jean-Prouvé

Gilbert Simondon is well-known as a philosopher of technics. But he is also famous for tackling a problem of scholastic metaphysics: the question regarding individuation. In tow comes yet another scholastic problem. Simondon challenges the modern notion of the individual. But he does so by placing the relation at the heart of the subject. The relation was considered by Aristotle as an accident. It is what may or may not occur. This is where Simondon intervenes. The relation no longer happens to an autonomous subject. It becomes intrinsic to its constitution. The relation, for Simondon, is constitutive of both the individual and its milieu. A special kind of relation, the trans-individual relation, is finally constitutive of the subject. Questions of metaphysics may seem somewhat anachronous. Yet they are, I would argue, highly topical also to the philosophy of technics. Our progressive co-evolution with the natural world can no longer be taken for granted. It is a relation that now forebodes the sense of the accidental, if not the catastrophic. Perhaps it is time to think of our relation with the natural world as a constitutive accident? As a necessary contingency that requires our utmost care?

Conférence : Is the Italian melodrama by chance?
Thursday 1 july 2021, 12h15 - 13h — Amphi Jean-Prouvé

Italian culture has melodrama in its DNA. It has been there since the very beginning of Italian cinema (the dive movies, the silent epics, Emilio Ghione’s serials). Then it had a new development coincidentally with the neorealistic effervescence, of which it offered a kind of lowbrow version. Between 1945 and 1960, melodramatic movies proliferated, not always in the shape of low budget uncomplicated productions. Refined filmmakers like Michelangelo Antonioni or Luchino Visconti, prestigious stars like Lucia Bosè, Raf Vallone, Silvana Mangano ou Vittorio Gassman, highly admired writers like Alberto Moravia or Pier Paolo Pasolini contributed. Original directors like Vittorio Cottafavi, Riccardo Freda or Raffaello Matarazzo (probably the very father of the genre) bloomed in it. The Italian aesthetics and dramatics of melodrama are close to the Latin-American or Hindi form of it because of its unabashed use of strokes of fate, turn of events, surprises, miracles, in one word: chance. The purpose of this presentation is to study selected forms of this fatum.

Conférence : Will Randomness Kill the Bête-Machine?
Friday 2 july 2021, 13h45 - 14h30 — Amphi Paul-Painlevé

The celebrated evolutionary biologist Richard Lewontin has remarked that “present day biology is the realization of the famous metaphor of the organism as a bête-machine elaborated by Descartes”. One can certainly recount the history of modern biology as the story of the success of the machine conception of the organism. However, the shortcomings of this determinist view are becoming ever more apparent. An important challenge is emerging in cell biology—a field long characterized by references to ‘circuits’, ‘programs’, ‘motors’, etc. Cell biologists resort to machine metaphors to conceptualise the microscopic structures and processes they study because machines are familiar and intuitively intelligible macroscopic objects of our everyday experience. The problem is that our mechanical intuitions often fail when we attempt to grasp the form and function of cells, as these exist in a world that it is totally alien to us. It is a very strange world, where the effect of gravity is negligible, but where the random dynamics of Brownian motion reign supreme. Importing engineering concepts in cell biology may have seemed like a good idea in the past, but it is now increasingly recognised that these are more likely to mislead than to illuminate, as they inadvertently project onto the messy and stochastic microscopic world of cells features that are only physically possible in the ordered macroscopic world that we (and our machines) inhabit.

Conférence : Is the universe beautiful by accident?
Saturday 3 july 2021, 14h30 - 15h15 — Amphi Paul-Painlevé

"The universe is not bound to be beautiful, and yet it is beautiful. Beauty remains a mystery. After all, the universe could have been nothing but real," wrote Francois Cheng. How did the universe create the shapes of galaxies, stars and planets? A curious chance in a world that is said to lean towards more and more disorder. A closer look reveals that the emergence of the complexity and uniqueness of forms, and therefore of beauty, is a natural, universal, and even fatal consequence of the laws of physics. Behind the eternal struggle between universality and particularity lie invisible components, links between stars and galaxies that are barely discovered today and which seem to hold part of the secret of the emergence of beauty. Astronomers have only a few particles of light at their disposal to reveal these invisible links, but there is no form that has not been born without generating light in a universe that tends towards an ever-increasing abundance of light.

He sees genes as simply templates for making the proteins we need. Genes are controlled by us, and that includes their random variations. He is Emeritus Professor at the University of Oxford.

Conférence : Does chance have the last word in life?
Friday 2 july 2021, 15h15 - 16h — Amphi Jean-Prouvé

How could purpose exist if all behavior is determined? Simply adding randomness to our view of the world does not, by itself, resolve the tension. It is necessary to use a multi-scale systems view of biology in order to include control processes by which randomness at all levels can be harnessed and so used by organisms. Purpose in organisms can then emerge naturally from the ways in which physiological harnessing works.

Conférence : What is random?
Thursday 1 july 2021, 10h - 10h45 — Amphi Abbé-Grégoire

Where does such a thing come from? What is the cause of this or that? How could such an event happen? How can we explain such a strange phenomenon? Every time we try to answer these kinds of questions, we see a path being set up to a bottomless pit, because we can only explain an event by adding to it its own anteriority, and so on: whatever starting point we choose, it appears each time as not being an authentic cause since it asks to be founded itself, that is to say, presented as being itself the effect of another cause, and so on. This is how the notion of causality raises thorny philosophical problems that constitute the counterpoint to those raised by the idea of chance: chance and causality are in fact correlated in the sense that the first unfolds in the shadow of the other. To invoke chance is almost always to admit that there is a difficulty in identifying a causal explanation. Chance corresponds in a way to the purgatory of causality. But does this purgatory really exist?

Eymard Houdeville is a machine learning engineer and a philosopher. His research work, at IDEMIA currently concerns neural networks architectures for computer vision applications. Eymard is especially interested in philosophy of sciences and epistemology of data sciences: what's the role of simplicity in experiments where we manipulate gigabits of data? Eymard wrote his master thesis at Ecole Normale Supérieure in Paris in 2018 about the irreproducibility crisis in modern sciences: how can we explain the fact that sciences is full of spurious and fallacious correlations? Worried about social consequences of these new ways to act and think, Eymard has started several vulgarization works and notably realized a tour of european hackerspaces in 2016. Eymard also holds a degree in politicial science of Sciences Po Paris and a bachelor in applied mathematics of Sorbonne University.

Conférence : How do you deal with chance when exploring the planets?
Friday 2 july 2021, 12h15 - 13h — Amphi Paul-Painlevé

Space and chance don't mix, that's for sure. "fly as you test and test as you fly" is pretty much the rule. The unexpected must be avoided at all costs. You have to plan for everything, even the worst. This applies to cases that are degraded by a breakdown that forces us to operate on three legs. But the chance is often present because exploring is to discover the unknown which by definition is ... unforeseen. When you land on the ground of a new world, you can't control everything and chance is part of the risk that engineers must translate into robustness. When 20 years ago, JPL was studying a lander on a comet, he had to consider that the ground could be as hard as concrete or as soft as powdery snow. This reflected our total ignorance of comets. Today, with Rosetta, we are able to reduce considerably the range of what is possible for the hardness of the ground. This project never came to fruition because the risk of chance was too great. The notion of worst case is very important in space, it sets the limits of the possible and allows engineers to work. Various examples will be presented where chance has had happy or unfortunate consequences.

Conférence : Guess what this conference is about?
Friday 2 july 2021, 13h45 - 14h30 — Amphi Abbé-Grégoire

The natural productions of chance often come as a surprise because we misrepresent them. They are sometimes counter-intuitive in that they often attract our attention, which has become a commodity that can be exchanged for money. Surprise, indeed, is a good strategy to attract the attention of our brain. This conference will explore some aspects of this cognitive incompleteness that pushes us to devote our mental availability to objects that are not always worth it.

Once upon a time, in the last quarter of the 20th century that seems so far away now, there was a group of computer scientists and mathematicians inflamed by a torrid discussion on a subject of major importance: whether or not to play Lotto, i.e. to have a tiny probability of winning enormously? Arguments for and against each other paraded with a confounding bad faith, usual in this type of assembly. After a few hours, the conclusion was reached that no definitive rational argument could be made for either of the two alternatives. However, two properties appeared certain.

Conférence : Can epidemics be predicted?
Saturday 3 july 2021, 10h - 10h45 — Amphi Paul-Painlevé

An epidemic recapitulates biology: it emerges from the multi-scale interaction between a parasite, its hosts and the environment. Whatever the contagiousness and virulence of a pathogen, it only becomes a danger to humans when the man-made conditions for its emergence and spread are met. Many attempts at emergence are unsuccessful, but when a microorganism manages to spread in human populations, at each stage of the epidemic, covering a field ranging from the molecular level to transcontinental transports, the stochastic processes at work have a decisive impact on its dynamics. Under these conditions, is it possible to anticipate an epidemic and/or predict its evolution?

The idea of a deterministic world seems to leave no room to free will. But, conversely, are we freer because the world evolves randomly? We shall try to show that this dead end in the philosophy of freedom originates from a presupposition that we are outside the world. If we start from the converse hypothesis, that we are within the world, then the question takes a completely different form.

Conférence : Is biological randomness just noise?
Thursday 1 july 2021, 17h30 - 18h15 — Amphi Jean-Prouvé

The scientific revolution of the 16th and 17th centuries was deeply mechanistic. From Galileo to Laplace, thus until the beginning of the 19th century, the ‘‘complex’’ was thought of as the “linear stacking of the simple’’. Poincaré, at the end of the 19th century, broke this vision of physical dynamics. Despite this, the power of the renaissance vision of the world and its successes, in particular in the construction of machines, biased our relationship with the living and the ecosystem: until the end of the 20th century, we continued to see the cell as a “Cartesian mechanism”, molecular interactions as a “Boolean algebra”. Even today, many think that we can exactly control organisms by editing their DNA, just like by programs, as writing and rewriting system to edit, we menage our digital machines. We will summarize certain aspects of this view of the world by sketching its direct passage, and for good reasons, by the theories of the elaboration and transmission of information which have had a key role in the contemporary understanding of the living and where the randomness is, in principle, just noise. It will then be a question of giving a new role to randomness and to the subject knowing / acting on the organisms and their environment.

Conférence : in progress
Saturday 3 july 2021, 17h30 - 18h15 — Amphi Jean-Prouvé

It is common to oppose chance and determinism. We should not. The set of determined phenomena (i.e., provided with a cause) can be classified into three components according to the way we apprehend them. There are necessary and predictable events at the scales at which we observe them, because we have laws to describe them (for example, the fall of a cannonball). In their regard, we do not generally speak of chance. There are necessary and unpredictable phenomena by default of lack of knowledge of the initial conditions at the current scales of observation (this is the example of the dice game). Finally, there are non-necessary, i.e. contingent, phenomena: their singular occurrence is multi-caused by unrelated causes. They could very well not have occurred at that moment (taking a flowerpot on the head). They are unpredictable, such as the occurrence of spontaneous behavior of a living being. The first two categories of determined events are necessary, the last two categories are unpredictable, and they are referred to as "chance". We can see that this term can be applied not only to determined but also necessary phenomena. We will see that within the framework of biological evolution, all "hazards" are mobilized.

We tend to think that computers (and thereby robots) only follow rules and are incapable of showing unpredictable behaviour or human properties such as creative thinking. We will show how this is a false preconception and how even humans can find it difficult to imitate computers at things such as generating randomness, how computers can be used as sources of creativity and measurement devices of human and animal behaviour and what does it mean for applications in everyday life such as knowledge discovery and Artificial Intelligence.

Regarding theory, she's studying what she calls "sound science-fiction", an emerging genre combining imaginary literature and sound experimentations. As for her creative writing practice, it is full of obsessions : the body as a territory, feminine intimacy, how we deal with our ecosystems and power. Her approach is both stamped by her political radicality and her sensitivity about the flesh and the world. She also gives creative writing workshops at universities, schools and differents social structures, because she believes that it's possible to generate poetry and imagination in everybody.

Conférence : To what extent randomness contributes to self-organization?
Thursday 1 july 2021, 14h30 - 15h15 — Amphi Jean-Prouvé

Organization, as a state as well as a process, is composed of two opposing elements. One of repetition, the other of variation, of the same and of difference. Repetition ensures stability, with the repetitive order of the crystal at the extreme; variation ensures the possibility of adaptive evolution, with clouds or volutes of smoke at the extreme. The stability of the biological self-organizations is ensured by the forces of physico-chemical attraction of the parts between them; the variety, by the conditions under which these forces act, counteracted by repulsive forces. In the absence of intentional planning, this is the effect of a greater or lesser amount of random fluctuations. A fundamental difference appears between natural machines such as organisms and artificial machines, even the most complicated ones, in their ways of reacting to temperature. Within the framework of probabilistic information theory, the association of repetition and variety is formalized by that of redundancy and complexity, with noise as a factor both of disorganization by destroying redundant information and of reorganization by creating complexity. Different examples will be presented of the application to biology of this principle of complexity through noise as a principle of self-organization.

Conférence : Do love stories for Proust come by chance?
Thursday 1 july 2021, 11h30 - 12h15 — Amphi Jean-Prouvé

Love has no necessity in Proust’s work. One falls in love as he/she falls ill. Love is a disease which falls on you like a virus and of which you wake someday healed, with no reason, wondering to yourself, how could I have fallen in love with that person? How could I spoil years of my life for someone who was not my type? It was just a bad moment to get through. If there is no necessity in falling in love, if it is apparently arbitrary, it still comes from what André Breton called “objective chance”, a mixture of chance and necessity. Necessity - in other words the Unconscious. And again in other words, there is some chance, but it is not by chance that there is that very chance! And if that chance makes one falls in love in Proust, its role, its emergence, belong to an etiology - I use the medical term on purpose for in Proust’s vision we are all ill, including Proust, who refused the very existence of love and even friendship.

Conférence : Was the universe a random creation?
Friday 2 july 2021, 15h15 - 16h — Amphi Paul-Painlevé

Or should we think that God is a random creation? Einstein wrote: “God does not play dice with the universe”. It seems that astrophysicists believe either in random or necessity, or a mix of the two as the case may be. Actually humans believe in random power. They consider it as a mighty spirit, which may individually bring luck, if it behaves humanely, or turn malicious in case of a bad fate. And they always hope its help. Random is a myth, but the one and only without a link with any collective storytelling. We may therefore question if any mythanalyse of random may even be possible.

Conférence : Does quantum physics explain random?
Thursday 1 july 2021, 15h15 - 16h — Amphi Paul-Painlevé

It is often believed that quantum physics brings the final proof that a true randomness is present at the micoscopic scale. Quantum mechanics is a thery inside which the indeterminism does not come from an incomplete knowledge of the world or from an uncertainty about initial states but from a randomness assumed to be essential at the core of subatomic events. I will examine if this position is mandatory or if it can be discussed. In particular, I will present theories alternative to quantum mechanics, some being considered as deterministic, and will analyze how randomnes is delt with inside them.

Conférence : What is the role of random in the evolution of the cosmos?
Saturday 3 july 2021, 17h30 - 18h15 — Amphi Abbé-Grégoire

The role of random in cosmology is part of the formulation law of quantum physics. The fundamental equation of physics, Schröedinger's equation, is deterministic; but Born's rule, the one that allows us to interpret the solutions of this equation, gives probabilistic answers. In the real world, this is supported by the notion of random. Random alone generates clutter; necessity (laws) alone generates monotony. Necessity allows matter to organize and become more complex; random allows diversity and creativity. Nature plays on both sides. It combines chance and necessity to make beings that are ever more complex and structured.

Conférence : Is random a point of view question?
Friday 2 july 2021, 16h - 16h45 — Amphi Jean-Prouvé

Some phenomena can seem random while they obey deterministic rules while others, on the contrary, seem perfectly predictable while they are in fact random... In this talk, we will discuss the different points of view that one can have on a physical phenomenon, points of view that could lead one to consider an event as random or not. This analysis, which will make us travel from chaos theory (and weather forecast) to quantum physics, will inexorably push us to ask the following question: does randomness truly exist?

Conférence : Is chance the limit of explanation?
Friday 2 july 2021, 10h45 - 11h30 — Amphi Paul-Painlevé

However one conceives of chance, it seems that what happens by chance cannot be explained. Chance may event be considered as the main limit to explanation and explainability. My talk aims at assessing this claim. To start with I shall justify it quickly and present the theories that philosophers of science have developed since the 1960s to analyze explanatory practices in the case of events that are random or known only probabilistically. These theories deal essentially with quantum or complex phenomena, but in daily life also there exist chance events that can be explained. The second part of my talk will analyze such cases. The main question will be whether and in which sense one can really think of them in terms of chance. This will lead me to ask whether it is always a good idea to try to explain what happens by chance. The last part of my talk will be devoted to this question. It will focus on noise in scientific data and on conspiracy theories.

Conférence : Is randomness right?
Thursday 1 july 2021, 12h15 - 13h — Amphi Abbé-Grégoire

Randomness was first used as a tool to achieve fairness. Pascal, in his treatise on the arithmetic triangle, develops fairness arguments to establish the basic rules of probability. These originis are mostly forgotten nowadays, certainly they do not appear in Kolmogorov's formalism, but they are now coming back with a vengeance. Nowadays, when people no longer trust each other or their governments, there is a longing for fairness and impartiality, and this is just what randomness can provide. We will study several examples

Conférence : Is chance God walking around incognito ?
Saturday 3 july 2021, 13h45 - 14h30 — Amphi Abbé-Grégoire

In the past, dice obeyed the gods: throwing them was a way for humans to know their will. For the world was a cosmos, in other words a totality as beautiful as it was orderly, of which no element, no mechanism could escape its destiny, its duty; neither chance nor risk existed then. They appeared when the astronomers of the seventeenth century broke the crystal spheres on which the stars circulated, when merchants began to criss-cross the seas and rationally manage the risk of losing their goods, when mathematicians invented probabilities. The gods seem to be leaving a world that looks like a casino. Charles Darwin wins the jackpot by claiming that the living are the fruit of random transformations subject to an intractable selection... But Albert Einstein is rebellious: "God does not play dice"; "chance is the pseudonym that God chooses when he wants to remain incognito", Albert Schweitzer adds. The game, which was relaunched by the scientists themselves, does not seem to be over yet. It remains for us to ask ourselves for which of the protagonists God himself has bet...

Conférence : Is our material formed and structured by chance?
Thursday 1 july 2021, 9h15 - 10h — Amphi Paul-Painlevé

Everything that is observable, including us, is made up of so-called atomic or nuclear matter. An atom comprises a nucleus of atomic mass A=Z+N, gathering Z protons (a particle of positive charge and mass equal to 1.6x10-24g) and N neutrons (electrically neutral and of the same mass as the proton). Z electrons of negative charge orbit around this nucleus (the number Z is said to be the atomic number of the atom and characterizes its chemical nature -1 for hydrogen, 6 for carbon, 26 for iron, and 92 for uranium. While the electron is an elementary particle, it has been known since the 1960s-1970s that protons are formed of 2 quarks u of charge +2/3 and a quark d of charge -1/3 while neutrons are made up of 1 u and 2 d. The behavior of these quarks and the gluons that "confine" them is governed by the strong nuclear interaction. The transformation of a u into a d (or vice versa) with the emission of an electron (or positron) and a neutrino (or antineutrino) is governed by the weak nuclear interaction. These two interactions are added to gravity and electromagnetism to be the set of fundamental interactions that act on matter at all scales. Is this structuring of matter and its organization at all scales due to chance?

He is a founding partner of the BrainFIT Institute, offering neuroeducational programs for the worklife. The ongoing technological revolution challenges our ability to adapt to an increasingly demanding lifestyle. Our brains - which have evolved over the ages to perform in a certain type of environment - are now faced with constraints that go beyond their native systems. Neuroscience and anthropology contain keys to the philosophers' "know thyself", but also to living well, with appropriate mental strategies, in today's world.

Conférence : Is chance an anthropological "unthinkable"?
Saturday 3 july 2021, 16h45 - 17h30 — Amphi Paul-Painlevé

Random is an anthropologically bizarre concept, to the extreme. While our brain is wired to attribute meaning "at all costs" and to identify causes - however imaginary - hidden behind phenomena, it postulates a void, an indeterminacy containing even the negation of any hope of finding any. This void is so foreign to our psyche that "random" is necessarily personified in everyday language under the disguise of “chance” or “fate” as if it were itself a character endowed with volition. In French, the word hasard comes etymologically from the great Arab culture of the Middle Ages. It remains a sort of shocking object in our belief systems. Many people in our society willingly say (preferably in private) "everything happens for a reason" or “it’s no accident that...” This is an epistemologically deviant but perhaps majority belief, as is believing in Angels: even if it is not supposed to be true according to our scientific ideology, most people do believe so anyway, sharing openly or not about it depending on the interlocutors and the social context.

In total, I spent 28 days in space. But why me? Why was I selected in the end, rather than my neighbor when we were only about twenty candidates, all perfectly capable, both physically, psychologically and intellectually? A space mission, from its conception to its implementation, represents a project of extreme complexity, as much for the technologies involved as for the cost management and coordination of the teams invested in the long run. As astronauts, we prepare for the worst by hoping for the best. As we approach liftoff, the crew is in complete confidence. They feel they are capable of dealing with every conceivable situation. In orbit, the main danger comes from the millions of natural micrometeoroids and artificial debris. From space, the view of the Earth is breathtaking. The atmosphere observed on its edge on the horizon is evidence that life on Earth is not very important. Land, water and oxygen are limited. Why is it so beautiful? Everyone has their own conviction. Some see God, others see chance...

Conférence : What if life were anarchic?
Friday 2 july 2021, 9h15 - 10h — Amphi Abbé-Grégoire

Genetics - fundamentally deterministic - hardly accounts for the wealth of experimental data demonstrating that randomness is omnipresent in life, including in the functioning of "genes". Whether in its strong version (a gene determines a character of a living being) or in its softened version now called "epigenetics" (the determinism of the gene is tempered by other factors, including the environment), genetics is thus contradicted: disorder reigns where a program was supposed to reign. To overcome this contradiction, it is necessary to recognize that random variation is the primary property of living beings and to draw the consequences. There is no intrinsic biological order that would determine life. Living beings are not centralized societies of cells obeying the orders of the genome or the environment, but communities of cells that are free and active in their own destiny, thanks to randomness which they use for their own benefit.

Conférence : How to prove that this number was really chosen at random?
Thursday 1 july 2021, 16h - 16h45 — Amphi Jean-Prouvé

Proving that a number was drawn at random is an easy question with difficult solutions. Often the proof is obtained by a draw in public with certified material and before sworn or unsworn witnesses and bailiffs (lottery). But what to do from a distance? Especially after the draw, long afterwards. We will examine the solutions provided by cryptography: on the one hand, how to properly generate random numbers and, if possible, with a generator for which one has a good mathematical proof of generation (we will observe the limits) and on the other hand how to convince a third party that this number was drawn at random. We will see that this requires a very precise definition of randomness and its simulation.

Thursday 1 july 2021, 13h45 - 14h30 — Amphi Jean-Prouvé

Most configurations that result from pure chance leave us indifferent. Some others, however, do not: coincidences, anomalies, an accident affecting a close relative… On these occurrences, one is tempted to say: "it didn't just happen by more chance! " One may be tempted to invoke some sort of “synchronicity”, the hand of fate, a hidden cheating or conspiracy. Is there a criterion for deciding whether only chance was really responsible for what happened? Probability theory proves insufficient to answer this question. A more adequate answer is provided by algorithmic information theory.

Conférence : Can the science of science fiction be the science of chance?
Saturday 3 july 2021, 16h - 16h45 — Amphi Jean-Prouvé

For the general public, science fiction refers to spaceships and aliens; it is therefore seen as a fiction mainly about physics or biology; it is not immediately associated with a science such as probability theory, the science of chance. Yet, without going as far as Boris Eizykman, who wrote in 1981 that science fiction should be called stochastic fiction, I shall argue that many science fiction texts, including some classics, give importance to the science of chance, to the point that it is possible to approach the history and philosophy of probability theory through the prism of science fiction.

Quantum physics is reputed to give an essential and inescapable role to chance, unlike its classical predecessor, which is considered to be governed by rigorous determinism. We will show that the situation is more complex and therefore more interesting : there is randomness to be found in classical physics and causality in quantum physics. These considerations lead us to question the capacity of science (here physics) to give a complete and coherent explanation of phenomena.

Molecular Biology Researcher

Jean-Pascal Capp is an associated professor at the National Institute of Applied Sciences (INSA) in Toulouse, an engineering school member of the Federal University of Toulouse Midi-Pyrénées, where he teaches molecular biology. He has been interested in molecular, cellular and tissue phenomena that cause cancer since his doctoral thesis on genetic abnormalities in cancer cells. He is the author of two books on cancer (Belin, 2012) and stem cells (Materiology, 2015), as well as numerous scientific publications on cancer. He developed an original concept based on the initial disruption of tissue equilibrium, breaking with a very genetic view of cancer. He does not deny an important role of mutations and other genetic modifications, but does not consider them necessary or sufficient to trigger the process which would be above all a tissue event. He is also a researcher at the "Toulouse Biotechnology Institute" research center, a laboratory supervised by INSA, INRAE and CNRS.

Conférence : What is the role of chance in the appearance of cancers?
Friday 2 july 2021, 11h30 - 12h15 — Amphi Paul-Painlevé

What is the part of responsibility in the appearance of cancers of the intrinsic and random, and therefore inevitable, cellular events and of environmental factors such as certain chemical compounds or certain radiations, which it is possible to protect against? This is the issue of a scientific debate launched in 2015 by a resounding scientific publication which has seen many developments since then. Ultimately, the question is whether to invest massively in prevention actions. This debate, focused on the role of genetic mutations in DNA, actually masks a set of other random phenomena which deserve to be mentioned in the appearance of cancers, in particular when we observe that healthy tissues may contain cells with multiple mutations thought to promote the development of cancer. We must therefore admit the existence of other early events of non-genetic origin and which are also intrinsically random. Finally, the observation of a great genetic and non-genetic heterogeneity between the cells of the same tumor confronts us with a very complex situation where different types of random phenomena are intertwined. Chance therefore certainly has a large place in carcinogenesis, but each of these random phenomena may have their role accentuated by exposure to environmental factors.

Conférence : Is there a general mathematical definition of what chance is?
Friday 2 july 2021, 10h - 10h45 — Amphi Abbé-Grégoire

There are several mathematical sciences of chance, the oldest and most developed of which is probability theory. However, strangely enough, this first theory does not really define what chance is and, for example, is unable to say whether or not the sequence of decimals of the number π is random or not. It therefore took a second mathematical science of chance to formulate a precise definition of chance that allows us to speak unambiguously of "infinite random sequence". This second science is linked to the theory of computation, mathematical logic and complexity theory. For this science due mainly to Andrei Kolmogorof, Per Martin-Löf and Gregory Chaitin "is random" means "is incompressible", which is demonstrated to be equivalent to "being unpredictable". With this theory, fundamental intuitions that classical probabilities could not justify now make sense. This unexpected theory of chance is now used in computer science, physics, psychology, and economics. It is also profound and gives a new philosophical understanding of the idea of chance.

Conférence : Is our sky the fruit of chance?
Thursday 1 july 2021, 12h15 - 13h — Amphi Paul-Painlevé

The position of our galaxy in the universe may seem contingent to us, so that the contemporary cosmological model assumes that we do not occupy a privileged place in space. However, is our position - in space and time - completely due to chance? This question will invite us to consider the role of quantum mechanics in the primordial universe, then that of the emergence of conditions favourable to the appearance of life and, in a much more speculative way, the apparent fine-tuning of the theories of nature and the place of our universe in a larger structure often referred to as multiverse.

Jean-Pierre Luminet is an astrophysicist, writer and international speaker. Researcher at the C.N.R.S. since 1979, he worked at the Paris Observatory until 2014. Today research director at the Laboratoire d'Astrophysique de Marseille, his scientific work on black holes and cosmology has made him internationally renowned. He was the first, in 1978, to numerically calculate the visual aspect of a black hole, an image confirmed in 2019 by telescopic observations. In 2003 he also made the front page of scientific journals around the world for his theory of a finite and "crumpled" universe. Winner of numerous awards, including the European Prize for Scientific Communication 2007, asteroid n°5523 bears his name in tribute to his work. He is also an Officer of the Arts and Letters. To his activities as a scientist he adds that of an author who is in turn an essayist, novelist and poet in a protean work where science, history, music and art are linked. He has published about thirty books, translated into a dozen languages, as well as CDs, DVDs and documentaries for television. His most recent book, "L'écume de l'espace-temps", published in October 2020, is devoted to the theories of quantum gravitation.

Conférence : Chance or emergence?
Saturday 3 july 2021, 12h15 - 13h — Amphi Paul-Painlevé

One of the obvious virtues of emergence is to formalize in modern language the old and vague idea that "the whole is more than the sum of its parts"; a very rich approach that takes the opposite side of reductionism - a philosophical position often pejoratively presented, but which nevertheless represented a necessary phase in the development of science. The emerging strata of the world roughly correspond to a certain hierarchy between the main disciplines of science. Atomic physics emerges from particle physics and quantum field theory; chemistry emerges from atomic physics, biochemistry from chemistry, biology from biochemistry, neuroscience from biology, cognitive science from neuroscience, psychology from cognitive science, sociology from psychology, economics from sociology, and so on. The result is an important question: is there a fundamental level in the hierarchy, and if so, how close are we to knowing it?

Conférence : Are extinctions avoidable?
Saturday 3 july 2021, 10h45 - 11h30 — Amphi Abbé-Grégoire

The 6th extinction is in progress but it is in fact the Nr. 7 regarding the geological time scale. In many discourses, we generalize by speaking about “unavoidable” extinctions. But what is a massive extinction? A critical look on the curves of biodiversity evolution through time shows, yet without minimizing the importance of the extinction in progress, that life crises are stochastic and multifactorial events: they occurred several times during evolution and impacted various clades in a differential manner, sometimes totally. Asteroid impacts, volcanism, eustatism (sea level variations), geomagnetic inversions, global climate changes, the causes are often various and their studies look like a good Agatha Christie’s novel with several murders at the same time. Pollution, deforestation, overfishing, greenhouse gases, the 7th extinction is clearly due to humans, but it is not the first time in evolution one species impacts so much the biodiversity. And even if “life finds a way” it is not the reason to stay inactive.

Conférence : Is randomness fundamental ?
Friday 2 july 2021, 16h45 - 17h30 — Amphi Jean-Prouvé

Randomness is generally considered according to a triple negation defining it in a different way each time. It would be the positive flipside of either the absence of finality, a lack of determinism, or a defect of knowledge (so-called "subjective" chance). In the first case, it would be opposed to God, in the second case to an intrinsic necessity, in the third case to an infinitely knowable reality. Each of these oppositions, however, declines the same underlying alternative: is chance only an effect derived from a reality that is causally or finally determined, or does it itself constitute a fundamental aspect of it? In one case, only the random effects of determinism have to be explained, while in the other, only the determined effects of randomness need be explained. Is this alternative itself indeterminate? Starting from a variation that can be qualified as random according to the triple point of view indicated, Darwinian natural selection theorizes these determined effects of chance and shows that a science of life is only possible by taking the second path of the alternative. It remains to be seen whether the living is itself only a random effect of a given physico-chemical reality or whether, on the contrary, the structure of the theory allowing us to think this can and must be generalised to the entire reality.

Conférence : How does chance affect history?
Saturday 3 july 2021, 12h15 - 13h — Amphi Jean-Prouvé

Chance affects history in a double way: it influences the course of events and our knowledge of the past. What would historians know about Ancient Egypt if, by chance, a French soldier from the Napoleonic army had not found a stone that allowed Jean-François Champollion to decipher hieroglyphs? Yet, historians have long been reluctant to study the influence of chance on history. History emerged as a science in the nineteenth century on the postulation that historians should only investigate “positive” facts whose origins were determinate. Modern generations of historians have opened new research avenues. They have written the history of chance and tried to comprehend this immaterial part of history, that could be called “hazard,” borrowing an Arabic word meaning “dice,” and by extension a “science of chance.”

Conférence : Do children misperceive randomness?
Saturday 3 july 2021, 14h30 - 15h15 — Amphi Abbé-Grégoire

From a young age, children are familiar with random patterns, such as raindrops on a window or falling snowflakes. They also have experience with random generators, such as dice and coins. Understanding randomness and chance is also central to playing games and sports, and for developing a concept of fairness. Evidence suggests that even babies have some basic intuitions about probability. Nevertheless, a key characteristic of random events is that, although the identity of the potential outcomes is known, the sequence of outcomes unfolds in a manner that is unpredictable to the observer. So how do we develop a good understanding of randomness? Do older children have a better understanding of random processes than younger children? What are the typical ways of misperceiving randomness, and how can we overcome our misconceptions?

Laurent de Wilde Laurent de Wilde
Pianist, composer, writer

Internationally renowned jazz pianist, Laurent de Wilde has been described as a exciting and passionate musician. Born in the United States in 1960, de Wilde spent his formative years (1964 to 1983) in France where he was immersed in French culture, music and literature eventually studying philosophy at the “Ecole Normale Supérieure” in Paris. Returning to the United States on a scholarship to further his musical knowledge, he studied jazz piano in New York where he resided for eight years. In the late 1980's he recorded his first albums with trumpet player Eddie Henderson and drummers Jack DeJohnette and Billy Hart. Returning to Paris in 1991, he continued his musical career touring throughout Europe, the United States and Japan. In 1993 he was awarded the Django Reinhardt Prize and in 1998 the “Victoires du Jazz”. In this period he also wrote his first book, a biography of Thelonious Monk that was published by Gallimard in 1996. The book received critical acclaim and has been translated and published in the United States, the U.K., Japan, Spain and Italy. After the turn on the century, de Wilde pursued a number of varied and intense projects including his Acoustic Trio, producing the album "Over the Clouds", In this period he also devoted himself to electronic music, a genre that challenged and inspired him to record six albums including “Fly” and “Fly Superfly”. He collaborated with artists such as the slammer/composer Abd Al Malik and comedian Jacques Gamblin. He ventured into TV with two documentaries for Arte on Thelonious Monk and Charles Mingus and released his second book "The Heroes of Sound " (published by Grasset), a saga of the inventors of keyboards in the twentieth century. Finally, to mark the centennial of Thelonious Monk's birthday and the twentieth anniversary of the publication of his Thelonious Monk biography, de Wilde's album titled "New Monk Trio" has been released.

Leila Schneps received her B.A. at Harvard University in 1983, and then moved to France to pursue her Ph.D. in mathematics at the University of Paris, where she later became a researcher at the French Center for Scientific Research. Although her main area is pure mathematics, she became interested some years ago in the way in which mathematics is used in criminal trials and medical diagnostics, two areas in which a close examination raised major concerns about serious errors being made due to misunderstandings and misuses of probabilities. Together with Coralie Colmez, she published a book called Math on Trial (Basic Books, 2013) detailing 12 cases of mathematical errors leading to miscarriages of justice from the end of the 19th century to today. Since then, she has become involved in working with the French police on efforts to bring Bayesian networks and artificial intelligence into the crime investigation community, and also in publicizing the problems with the current medical practice of rigidly diagnosing shaken baby syndrome in the presence of certain symptoms based on a faulty understanding of the results of certain statistical studies, leading to the arrest of parents and the breaking up of families.

Conférence : How to judge the rarity of a coincidence?
Thursday 1 july 2021, 13h45 - 14h30 — Amphi Paul-Painlevé

There is a particular type of court case that is characterized by a lack of concrete evidence. There may have been, for example, one or even several deaths, with no solid indication that they were due to murder. In such cases, the prosecution bases its arguments essentially on the principle of probability, asserting that if the accused were truly innocent, then we would be faced with an unbelievable coincidence. At this point, a proper calculation of the probability of the observed events is crucial. But when making such a calculation, we often come upon some very surprising observations, often due to the fact that when intuitively assessing probabilities, we tend to forget that we live among so many millions of other human beings that any strange thing that can happen probably actually will happen somewhere, at some point. Then, once the probability of the observed events is correctly computed, we must not forget to compare it with the probability that the accused is really guilty. A classic fallacy consists in assuming that if the probability of an event is minuscule and yet the event occurs anyway, "some must have done it on purpose". These illusions and false intutions lead regularly to grievous miscarriages of justice.

Louise Marc Louise Marc
PhD student in medical physics

Louise Marc is a PhD-candidate at the University hospital of Zurich in the department of Medical Physics, more concretely in cancer treatment by radiotherapy. During her Bachelor studies in Physics at Technische Universität Darmstadt (Germany), an exchange year at École Centrale Paris followed by a Master in Applied Physics at École Polytechnique Fédérale de Lausanne (Switzerland), she could get in touch with different domains at the interface between physics and medicine. Determined to improve and innovate in the health field with a physicist's approach, she is interested in interdisciplinary questions. Her current research is about how to improve the conventional radiotherapy, i.e. photontherapy, in terms of precision through the use of protons. The so-called proton therapy is more costly but generally much more precise. Thus, it potentially represents in combination with the use of photons, a general improvement for radiotherapy in clinics. Louise is passionated about music, and lives her passion particularly by playing the piano since her childhood.

Lucas Debargue Lucas Debargue
Pianist and composer

Born in 1990 in Paris, Lucas got his first musical impressions from the rock and pop music that his parents were listening to. Around his 10th year he found, among their collection, a recording of a Mozart piano concerto. This discovery changed his life forever : the so-called « classical » music would become a dominant passion for him, before drawing and reading. Very curious by nature, Lucas didn't follow an usual path to musical life. After a scientific degree, his sensitivity brought him to literature studies in university. For several years he played the bass guitar in a band with his friends, before earning his life by accompanying singers in a Montmartre piano bars The encounter with Rena Shereshevskaya in 2011 was decisive : from this moment, Lucas considered piano as his full-time activity. Her advises and support made him able, in 2015, to get the 4th prize and critics prize at the XVth Tchaikovsky competition in Moscow. Then, engagements never ceased to come from all over the world : Lucas performed in Paris Philharmonie, London Wigmore hall, Vienna Konzerthaus, Carnegie hall in New York or Tokyo Suntory hall ; as a chamber musician he already joined Gidon Kremer, Janine Jansen, Martin Fröst, Karine Deshayes among others, and played as a soloist under the baton of Mikhail Pletnev, Valery Gergiev, Vladimir Spivakov, Tugan Sokhiev. Thanks to a strong collaboration with his label Sony, he already released five albums, among which a monumental box with 4 discs devoted to Domenico Scarlatti in 2019. Lucas is also the author of about twenty pieces : piano trio and quartet, string quartet ; cello, violin sonatas ; solo piano pieces and songs. He lives and works near the place where he grew up, in the north of France.

Conférence : Are dreams randomnly created ?
Thursday 1 july 2021, 15h15 - 16h — Amphi Jean-Prouvé

Are dream just the same as Rorschachs tests, or even as these suggestive rock formations whose content is only derived from the meaning we project on them ? That’s at least what believes neuropsychiatrist Allan Hobson who coined the "activation synthesis" theory : to him, dreams are not, as Freud would have it, the fruit of a intention hidden away from the dreamer, but rather the outcome of the random activation of neurons in the cerebral cortex to which the brain does its best to attribute a meaning.Against such a theory, we will show that while scientific research on dreams can hardly establish that dreams manifest an underlying intention, it does give very good arguments to maintain that they are not a pure product of chance. It is hard to get, for instance, how the formal coherence of dream imagery could be created by chance when it is well established that it is made up of highly diverse memories. To put it differently, dreams may not be meaningful in the way that words of the language are, but they have at least something of a syntax. And yet, one must remind what we call the dream : it does not only consist of an involuntary hallucinatory production, but it also encompasses a set of cogitations, reflections, inferences and decisions that are brought to the dreamer's mind by this involuntary imagery and which seems to be analogous to the wakeful cognitive activity.These cogitations do seem to indicate intentions in the course of the dream. As for the characters that come across our dreams, there is riveting way to find out whether they think : testing their insight and their words by questioning them in lucid dreams.

Conférence : Can chance be managed?
Thursday 1 july 2021, 10h - 10h45 — Amphi Paul-Painlevé

Today, chance evokes gambling, the search for strong emotions, the lure of winning and even the ultimate feeling of living. Chance is then of the order of the living and the emotion. In management, we don't talk about chance, we talk about risk. Risk is a probability, so it is a rational calculation. More precisely, it is the probability that an event will occur, the consequences of which are feared. Risk management is based on a simple principle: we evaluate the probability that the problem will occur, we quantify the damage it may cause, and we look for solutions that cost less. Risk management has developed in many areas: we can think primarily of production, where we can avoid accidents to people, but we can also manage financial risk or legal and social risks, for example. However, the calculation of probabilities often lags behind what organizations experience. Chance, when it combines events and human actions, is also present in the effects of crisis on organizations; a one-off crisis, or a crisis that lasts according to the evolution and exchanges of living beings. In the face of crises, proven methods of risk management are not suitable, because chance is precisely out of the question. But if chance can provoke crisis, it provokes above all new forms and figures, and for those who are aware of it in time, it can be a source of opportunities, creativity and innovation, which are also outside the field of risk management. Thus, if chance is linked to the game of life and emotion, it is also because it causes a hitherto controllable universe to leave - at least in appearance - through the emergence of another universe in the making and whose rules we do not know. Chance provokes irreversibility, and in this it is opposed to risk management, whose main function is, on the contrary, to maintain the status quo. With the irruption of chance in its management, the organization has to face evolutions that frighten because they change routines and solutions to the established efficiency. Contrary to change projects, chance cannot be controlled or decided upon, it arises by issuing a challenge, and the art lies in anticipating in time the new rules of the game it imposes.

Conférence : Are associations between living species random?
Friday 2 july 2021, 14h30 - 15h15 — Amphi Abbé-Grégoire

The living world is made of associations: parasites and symbionts surround in number each organism, each species. Even more, these associations shape the functioning of the organism, its ecological and evolutionary success, so that at the end one can doubt on the relevance of the notion of organism as such! But how did these associations emerge? And how did they come to occupy such a prevalent role? The emergence of associations between living things is the result of chance, but also of natural selection. The same game between chance (especially drift) and selection is found in their subsequent evolution. It allows in particular the emergence of dependence, this so frequent state where one function can no longer be performed without the partner. Fungi and plants, bacteria and animals, animals and plants or fungi: thanks to multiple examples, we will discover the evolutionary pathways of associations between living things.

It is interested in the uses and impacts of emerging technologies (AI, pervasive systems, immersive reality, robots...) in socio-domestic and professional activities, and in particular in their conditions of acceptance located -in and by the activity- as well as their effects on the quality of life at work and the well-being of employees. These field research-interventions, carried out within the framework of multidisciplinary scientific and industrial consortiums, have given rise to several books and research articles.

Conférence : What is the role of chance in digital dispersion at work?
Thursday 1 july 2021, 16h45 - 17h30 — Amphi Jean-Prouvé

The question of the use of technologies, through their status and their pre-eminent role in professional activity, raises questions in terms of the fragmentation and dispersion of work, the disarticulation of spheres of life and activities (remote work, telework, management of (de)connection), and temporal pressure (over/hyper-connection). The individual thus finds himself immersed in the sandstone of interruptions and digital demands in professional contexts that he neither knows nor masters, and for which he must nevertheless deploy the appropriate resources to deal with them. This dispersion of work is often perceived as a constraint because it generates a significant mental and psychosocial load to adjust, with significant impacts on well-being and the loss of meaning of work. However, finding oneself by chance in another context can also opportunistically become a resource, by encouraging creativity through serendipity, i.e. the ability to make an unexpected discovery by chance and to grasp its usefulness.  Everything depends on the control, the room for manoeuvre and the power to act that the individual has.

Conférence : Does the measurement make it possible to control chance?
Thursday 1 july 2021, 17h30 - 18h15 — Amphi Paul-Painlevé

The purpose of the measure is to set benchmarks, whether it is to establish scientific construction, to achieve technological prowess, to characterize the terms of trade, to model phenomena and to serve as a basis for decision-making. Its ideally objective and reproducible character establishes certainties, pacifies interactions, provides evidence, supports arguments... and gives rise to forms of quantophrenia. Since 2019, metrological references all refer to the constants of nature. But one of the key words in metrology is "uncertainty"! This quantitative concept, which is essential to give meaning to a result and to exploit it, refers to a rigorous evaluation methodology, consensual on a worldwide scale, taking into account the intrinsic variability of quantities, the reality of measurement systems, the quality of the references used, the ambient conditions... and the age of the captain. Uncertainty is the basis of risk assessment: a form of hazard control? Photo Credit © Dircom Cnam – S. Villain

Conférence : Is hazard necessary to enact novelty in biology?
Thursday 1 july 2021, 10h45 - 11h30 — Amphi Paul-Painlevé

How does it happen that populations of clonal cells show a bewildering cell-to-cell variability – both phenotypic as well as genomic - even when their environment is kept homogeneous and constant? Until the eighties, the heterogeneity in isogenic cells was largely neglected by mainstream. Nowadays, this phenomenon is recognized to play a role in the development of biological systems, sometimes even a functional one, rather than always being a mere nuisance. Indeed, gene expression stochasticity provides the flexibility needed by cells to adapt to perturbations that challenge the system homeostasis. This remarkable feature explain why the genotype-to-phenotype mapping is not one-to-one but one-to-many. However, if gene expression is subject to significant stochastic fluctuations, from where ordered configurations can emerge? Several lines of evidence suggest that biophysical constraints can contribute to determine a directionality to differentiation processes as, for example, epitomized by naive stem cells undergoing differential lineage specification in response to diverse physical properties of the microenvironment. Cells can escape their inherent stochasticity when a regimen of proper constraints determines how physical/molecular inputs are “recognized” as signal or noise, thereby allowing the emergence of a well-designed phenotype, without requiring any prior “instructive” signal.

Conférence : Does art like chance?
Thursday 1 july 2021, 9h15 - 10h — Amphi Jean-Prouvé

The anecdote is old: with an angry gesture, the painter throws in the towel! The dog, which until then had refused to do so, immediately drools generously. Although no work by Protogenes has reached us since its creation in the fourth century B.C., the little story - told by Montaigne in the Essays - points out very early on the crucial presence of chance in creation and suggests that art, like all other areas of life, cannot escape it. From antiquity to the present day, many works thus write a certain history of art that borrows from unpredictability and unpredictability. A history of art full of processes discovered inadvertently, of processes imagined following an accident, of random practices adopted out of conviction. Sometimes radically excluded, sometimes used as a leaven, and even as an explicit, even exclusive means, chance is legitimized in art. Whether it is to escape reason or to get closer to nature, to explore the subconscious or to cultivate the imagination, artists are attentive to its signs and invent practices capable of escaping them but revealing like the divinatory rites of the ancient Delos. Aristotle asserted that art loves chance and vice versa. It remains to be ascertained.

Conférence : What does Shakespeare teach us about the games of love and chance?
Thursday 1 july 2021, 10h - 10h45 — Amphi Jean-Prouvé

On the face of it, chance plays very little part in drama where the characters' every move is predetermined by the author. Yet, in his plays, Shakespeare repeteadly reminds the audience (and the reader) that our lives tend to be ruled by chance, rather than order. We may have our « exits and entrances », as Jaques famously proclaims in As You Like It, real life usually bears little relation to a perfectly choreographed theatrical performance. In this lecture, I will study the interplay between love, chance and fate in A Midsummer Night's Dream and a few other Shakespearean comedies with a view to shedding some light on how chance was conceived of in early modern England.

Conférence : Higgs Boson, I presume?
Friday 2 july 2021, 9h15 - 10h — Amphi Paul-Painlevé

Albert Einstein, one of the fathers of quantum mechanics, could not quite accept it: "God doesn't play dice", he summed up at the 1927 Solvay congress which brought together the top physicists. And yet subatomic phenomena, described by quantum mechanics, are governed by probabilities. Random drawing. Chance. But then how can particle physicists claim to have discovered the Higgs boson? What does it cover? What do the results look like and how do we interpret them? Together we will track down the intervention of chance in the hunt for the last of the elementary particles to be discovered.

Conférence : Does the random regular?
Saturday 3 july 2021, 9h15 - 10h — Amphi Jean-Prouvé

When we think of "chance" or "random" we are more inclined to associate these notions with disorder than with order. Moreover, chance is often synonymous with unpredictability. However, random phenomena obey very strict mathematical rules: although a particular occurrence of a random phenomenon is inherently unpredictable, the statistical properties of a cohort of independent random phenomena are completely predictable. An example of such a property is the law of large numbers, which states that the probability of an event is equal to the asymptotic frequency of an (infinite) sequence of independent realizations. It is this "regularity" of chance that makes it possible to base statistics and extract information from real data.

Almost all of us experience surprising events from time to time... too surprising to be explainable, so we think, by chance. Such events may then give rise to conspiracy theories, rumours, even pseudo-scientific theories! Rather than dwell on the events themselves, why not talk about our astonishing astonishment? The effect of ignorance, probabilistic paradoxes, or neglect of certain important aspects of reality are among possible sources of our insight that, actually, nothing happens by accident.

Conférence : Is chance hidden in the phylogenetic tree?
Friday 2 july 2021, 13h45 - 14h30 — Amphi Jean-Prouvé

The phylogenetic tree is a picture as old as the pioneering book Philosophie Zoologique by Lamarck (1809). Fifty years later, Darwin’s Origin of Species includes the first modern tree demonstrating descent with modification .Yet, the criteria on which the reconstruction of the history of evolution is based, have always been discussed, transformed, questioned, and are still today. On the side of mechanisms responsible of biological evolution, and consequently of the relationships depicted by the phylogenetic tree, chance is a subtle and embarrassing concept. The role of chance in phylogenetics is discussed from a structural viewpoint, that is, in trying to separate the pattern of relationships from the evolutionary processes. As counter-intuitive as it can be, the power of attraction of stories (and the phylogeny is one) does not help in the discussion.

It disturbs some and reassures others. It can be a source of error and determine aberrant behavior, as in superstition. But we can detach the idea of chance from the principle of unhappiness. The idea of chance can give our lives a harmonious meaning and inspire calming behaviors. Through several examples taken from everyday life we show that we can come to terms with the idea of chance and, even better, make an alliance with it and rejoice in it.

Conférence : What is the chance for choice ? The comedy or tragedy of chance in film
Saturday 3 july 2021, 11h30 - 12h15 — Amphi Jean-Prouvé

This paper analyses the interactions between choice and chance. What place does chance leave for choice? Is there a difference in the chance of comedy to that of tragedy, between Charlie Chaplin’s The Kid (1921) and the South African film Tsotsi (directed by Gavin Hood, 2005), two films that draw their inspiration from the same impetus: the fortuitous discovery of a baby in a car? Comedy rarely puts up barriers to the inhabitual and Chaplin’s good-hearted tramp easily accommodates the abandoned infant. Choice gives way to comedy. In contrast, the baby in the car forces the eponymous petty gangster in Tsotsi to confront his own unfinished childhood and a series of existential choices. In a different vein, John Ford’s western Stagecoach (1939) presents the chance birth of a baby girl, Coyote, in the desert between Arizona and New Mexico, amidst an assortment of passengers thrown together at random. With his usual talent, Ford redistributes their choices, fates and destinies.

Conférence : Does a space launch leave room for chance?
Friday 2 july 2021, 9h15 - 10h — Amphi Jean-Prouvé

Anyone who has ever followed a space launch, from the French Guiana Space Center or behind a screen, will have noticed the concentration that drives the teams during the very last operations of the final countdown and during the launch sequence… before joy settles on the faces when the satellite is injected into orbit. Concentration, because each launch requires the mastery of an infinite number of parameters treated with extreme rigor and thoroughness. Joy, because despite the fact that nothing is left to chance, some hazards – for example weather conditions – make each space mission a unique adventure. One thing is certain: with 40 years of experience, Arianespace has constantly reduced, launch after launch, the role of chance in space missions.

Conférence : How much certainty is there in randomness?
Thursday 1 july 2021, 14h30 - 15h15 — Amphi Abbé-Grégoire

How can an accumulation of completely random and unpredictable events generate certitudes? Track and quantify certainty in randomness is at the core of the mathematical theory of probability and statistics, with surprising benefits: journals can announce with certainty the result of an election with only 1% of expressed ballots, and seismologists can predict with precision the number of earthquakes occuring in 2021, whereas earthquake forecasting remains a great mystery of sismology. These certitudes become even more surprising when they undergo a threshold effect, in particular in statistical physics: two disordered random systems, very close in their parameters, can behave in totally different ways, yet in a completely predictable fashion.

Conférence : What can we expect from random?
Saturday 3 july 2021, 14h30 - 15h15 — Amphi Jean-Prouvé

It is customary to place the origin of the mathematical theory of probability with the resolution of a practical problem: two players have their game interrupted before fate has determined a winner; how to determine a fair distribution of bets knowing the score at the interruption? In other words, how much of the total bet can each player expect to get? Through this example, the concept of mathematical expectation appears. It is now found in all the modelizations and calculations related to random: from our hopes in the drawing of a lottery to our life expectancy and the estimation of prices in financial contracts. Let's look at the historical development of this concept and its relevance in translating our intuitive perception of hope.

Conférence : Does random lodge itself in the heart of the stars?
Friday 2 july 2021, 15h15 - 16h — Amphi Abbé-Grégoire

Many hypotheses were put forward to understand the nature and origin of the prodigious luminosity of the Sun. At the beginning of the 20th century, physicists understood that the fusion of light elements into heavier ones could provide the energy that allows our star to shine for a long time: the fusion of four hydrogen nuclei into one helium nucleus can provide the Sun with enough energy to shine for billions of years. However, it remained to be understood how two nuclei, carrying a positive electric charge, can come close enough to fuse despite their electrostatic repulsion. In this lecture, we will see that the physical process that allows stars to shine for such a long time is based on randomness and that it manifests itself in many other situations.

Conférence : Why me?
Friday 2 july 2021, 16h - 16h45 — Amphi Abbé-Grégoire

When chance, destiny, fate or misfortune strike us cruelly, the question "why me? "emerges quite naturally. But the truth is that this question could be asked at any time. Why am I me, here, now, and not someone else? And why are we all "me," when we might as well have been anyone, or even anything? Why am I the one writing these lines, and not you? And why am I writing these particular lines, and not others? Are we, at any moment, the target of mysterious games of chance? Unless, of course, all these questions are wrongly asked, and result only from a pernicious illusion of the mind. This presentation attempts to update the presuppositions of the question "why me?", by mobilizing recent research on the nature of the "true self" in neuroscience and cognitive psychology.

Conférence : Is the randomness of mutations the only engine of evolution?
Saturday 3 july 2021, 13h45 - 14h30 — Amphi Jean-Prouvé

In 1859, in his book "On the Origin of Species", Charles Darwin explains that evolution is based on random variations which are transmitted in a hereditary manner and are then sorted by natural selection according to the environment. However, he could not explain the origin of these "variations". The answer to this question came at the beginning of the 20th century by the advent of genetics and the discovery of mutations. In the middle of the 20th century we finally understood the nature of these mutations. In evolution, is chance the sole result of random mutations in DNA? Today, we discover that the environment interacts with the expression of genes: there is inheritance without genes, it’s epigenetics. We also discover that gene expression is a random phenomenon in which a gene has a certain probability of being expressed or not. The stabilization of the system would come from external signals and from a phenomenon that Jean-Jacques Kupiec called cellular Darwinism (a natural selection at the level of the cell). So, what happens at the organism level also happens at the cell level.

Conférence : Can Humans Tolerate a Random World?
Thursday 1 july 2021, 17h30 - 18h15 — Amphi Abbé-Grégoire

It has been said that, as nature abhors a vacuum, human nature abhors uncertainty and absence of meaning. Although we have remarkable powers of perception, we often see order where there is none and think things happen for reasons that cannot be supported by evidence. We invent superstitions and other irrational notions to erase the randomness of the world. People vary in their need for order, control, and tolerance of ambiguity. When asked to simulate the random behavior of a coin flip, humans often fail and are only able to duplicate randomness after extensive training. Yet tolerance of ambiguity is an essential feature of scientific thinking and is associated with greater well-being in stressful situations. Given that the world we face often appears arbitrary and unpredictable, can we learn to live with randomness?

Conférence : Does our brain flip a coin?
Friday 2 july 2021, 12h15 - 13h — Amphi Abbé-Grégoire

What if our ability to make decisions was more a matter of chance than a rational process? It has long been recognized that in humans, decision-making is the result of a cognitive and psychological process: the mind decides, the body obeys. However, the pattern is reversed: the decision-making mechanism is produced by brain matter. It is a random phenomenon that results from competitive processes within a network whose architecture has changed little since the first vertebrates. The extraordinary development of the cortex, which made possible the development of great abstraction capacities, has not changed the initial structure of the decision network: the process retains its random nature, which limits the ability of homo sapiens to reason rationally. As a result, when an individual weighs the pros and cons, he does nothing more or less than rely on random virtual dice. Learning therefore consists in casting these dice in its favor ... But what, according to purely economic criteria, is only a limited rationality, is perhaps the price to pay to keep the great capacity of adaptation, main characteristic of the human species

Conférence : What is the role of chance in the origins of life?
Friday 2 july 2021, 17h30 - 18h15 — Amphi Jean-Prouvé

Searching for the origins of the life is not only manifesting curiosity for an elusive historical event, but rather one of the ways to better understand what biological life is. However, considering that life is an historical process, there is a paradox in wanting to grasp it at its very dawn, precisely when it was without history. This can be solved it by considering a deeper temporal dynamic, where the very notion of the appearance of life can be replaced by a more gradual vision, in which chance has never ceased to play a role, since evolution from mineral forms to those of living things. It is therefore the transformations of the role of chance that can enlighten us here, and be rich in teaching for research that aims to recreate life in the laboratory or to look for it elsewhere in the universe. Rather than a docile and determined phenomenon, the random dynamics remind us that the originality of biological life resides in its necessary and permanent inventiveness.

She taught French in South Africa where she had performed with William Kentridge in « Ubu Rex » during her student years. In 1981, like Kentridge who came to study theatre, she returned to France to meet Henri Michaux in Paris, where he died in 1984. In 1999 she organised a centenary retrospective of his art works at the Whitechapel Gallery in London. She is passionate about contemporary art, experimental theatre , writing and interculturality.

Conférence : How far can the artist trust randomness?
Friday 2 july 2021, 14h30 - 15h15 — Amphi Jean-Prouvé

To what extent do the creative processes of the two proteiform artists, Henri Michaux and William Kentridge, rely on chance ? The Johannesburg-born Kentridge came to Paris in his twenties to study mime and theatre at the Ecole Jacques Lecoq. He discovered then that acting was not to be his path. Possessed by a revolutionary utopian vision that he felt sure was necessary to counter the unjust and absurd political reality of his country, he was seduced by a Dadaist-type cacophony where poetry, performance, art and industry, could be randomly combined into a new coherent order. Henri Michaux, having left Belgium at 20 to sail across the world, found himself a published poet in Paris by the age of 24. Refusing in 1965 « Le Prix National des Lettres », his quest for inner freedom would lead him to blindly follow a pencil line on a blank page to new adventures. He would create by allowing images to appear or disappear or simply to reflect gesture or vibration. He could finally question representation. Michaux has been exhibited in over 300 galleries around the world, and still in Paris in 2020. Kentridge would advance when he could erase, embrace error and risk. He is considered one of the greatest contemporary creators ever, rewarded by the prestigious Praemium Imperial Prize in Japan in 2019 and, in France, a retrospective at the LAM in 2020.

Conférence : How is chance irreducible?
Saturday 3 july 2021, 15h15 - 16h — Amphi Jean-Prouvé

There is in chance the idea of something ineliminable, dreaded, insisting, which, enables signification, shows up to today the incompleteness of an established knowledge – a hole - which solicits the subversion of traditions for breeding newness. The landscape painter, William Turner, provides an overview on it. I paint what I see, but not what I know, he said. This singular “gaze”, if it provoked the taunts of colleagues, determined him to break free from classicism in order to paint what was imposed on him as a never-seen-light before. This new violent irreducible knowledge isolated him, but chance didn’t allow his ”gaze” to be an accident in the art history. The art critic and poet, John Ruskin, was able to see the intelligible in what the artist saw, giving resonance to ideas that reverberated from Marcel Proust through the 1960s, when Turner’s paintings left the Tate Gallery for a worldwide exhibition, till today with art historian Pierre Watt’s book shedding light on the Turnerian myth. In between, from his practice, the psychoanalyst Jacques Lacan, instructed us about the stain function: “pure presence”, the “gaze” calling his gazer. With colour, the stain irrupts in a Turner painting, a dazzling light making a hole in the landscape, so that by contingency, the artist’s “gaze” becomes symptom of the social sphere.
