Grandes Conférences du CRM
The CRM's "Grandes conférences" series invites scientists with a gift for communicating the most exciting recent developments in mathematics to a curious general public. From cryptography and quantum computing to chaos in meteorological or financial systems, and brain imaging or revolutions in biotechnology, all of the conferences reveal the power and beauty of cutting-edge mathematical research in a language accessible to all.


You are invited for half a day to discover the omnipresence of mathematics surrounding you, their creative and playful sides. You can attend the whole range of activities or join for a particular activity. Activities are being held at Pavillon André-Aisenstadt de l'Université de Montréal. | Read more

The Evolution of Cooperation: Why We Need Each Other to Succeed
Martin Nowak (Harvard)

During his upcoming Public Lecture, evolutionary biologist Martin Nowak, author of the best-selling book SuperCooperators, will share his cutting-edge research on the mysteries of cooperation. According to Nowak, many problems that challenge us today can be traced back to a tension between what is good and desirable for society as a whole and what is good and desirable for an individual. This conflict is illustrated in global problems such as climate change, pollution, hunger, and overpopulation. Nowak argues that cooperation—not competition—is the key to the evolution of complexity. | Read more

The Mathematics of Evolution
Robert Griffiths, University of Oxford 

Genes are transmitted randomly: this is why probability, a branch of mathematics, is used to model evolution within species. The lecture will give a non-technical overview of some models and explain the two-way interaction between mathematics and population genetics. Starting with the famous model of Wright-Fisher in the 1930’s, it will move to the revolutionary way of looking at evolution introduced by Kingman in 1982: instead of looking forward in time, we look backward! DNA data became available in the last decades and statistics now plays a crucial role in determining the ancestral trees back in time. A stunning application is the identification of hotspots of recombination, where chromosomes are more likely to break on reproduction. | Read more | Slideshow  | Video of the conference

Les ponts de Königsberg, les digues de Hollande et la chute de Wall Street
Paul Embrechts, ETH Zürich 

Notre planète, la Terre, fait non seulement face à de nombreux défis sur le plan environnemental, mais elle est également menacée par la complexité des infrastructures sociales conçues par l’homme. Je vais discuter des défis que cela nous pose en utilisant 3 exemples autour la modélisation des réseaux et des événements extrêmes: le problème du parcours sur les ponts de Koenigsberg, comment protéger les digues de Hollande, et la cause de la crise des surprimes de 2007-2009. | Read more | Slideshow of lecture

Peirce The Mathematics of «Fracking»
by Anthony Peirce, University of British Columbia

"Fracking" is used by the oil and gas industry to enhance the production of hydrocarbons. Recently there has been considerable controversy surrounding the fracking process due to environmental concerns. Fracking makes use of a process called hydraulic fracturing (HF) by which tensile fractures are induced to propagate in brittle materials by the injection of a pressurized viscous fluid. | Read more

The Mathematics of Light and Sound by Nilima Nigan (Simon Fraser University)

Our perception of sound and light informs much of how we experience the world. We see glorious rainbows and hear the summertime chirp of crickets; we wonder about invisibility cloaks and the twinkling of distant stars.Our fascination with light and sound has informed much intellectual and scientific thought. The ancient Greeks noticed the interplay between overtones and musical notes; Euler and Newton thought about the very nature of light

D'Einstein à Wheeler : la dualité onde-corpuscule mise en lumière  par Alain Aspect, Institut d'Optique, Palaiseau

Photo: Jean-François Dars

Depuis le tout début de la Mécanique Quantique, le phénomène d'interférence entre chemins séparés relatifs à une seule particule n'a cessé de fasciner les physiciens, comme en témoigne les réflexions d'Einstein il y a un siècle, puis le cours de physique de Feynman dans les années 1950. Ce qui n'a longtemps été qu'une expérience de pensée, destinée à montrer le caractère révolutionnaire du concept de dualité onde-corpuscule, a finalement pu être réalisé, grâce au développement de la première véritable source de photons uniques. Nous avons même réussi à mettre en oeuvre le schéma appelé «Choix retardé de Wheeler», qui met encore plus en relief l'étrangeté de la dualité onde-corpuscule, lorsque ce concept concerne une seule particule.

Les grandes tendances dans les
pêcheries du monde et
leurs effets sur les écosystèmes

Daniel Pauly (Fisheries Center and Zoology, UBC)

Since the end of the second World War, the spread of industrial fisheries led both to increases in catches and successive crashes, which began to affect global catches in the 1970s, and intensified in the 1980s and 1990s. In response, the industrialized countries of the Northern Hemisphere redeployed their fishing effort in the waters of developing countries, and beyond into the Southern Hemisphere, all the way to Antarctica.  This geographic expansion is now completed and global catches, which peaked in the late 1980s, are now declining, while the damage to marine ecosystems and biodiversity continues to increase, and effects of global warming begin to be felt in numerous fisheries. This lecture will illustrate these trends, discuss their implications and propose some remedies. | Read More

From Aristotle to the Pentium
Moshe Y. Vardi (Rice University)

Logic started as a branch of philosophy, going back to Greeks, who loved debates, in the classical period. Computers are relatively young, dating back to World War II, in the middle of the 20th century. This talk tells the story of how logic begat computing, tracing the surprising path from Aristotle to the Pentium. This is a story full of both intellectual drama, as well as real-life drama, with most of the characters dying young, miserable, or both. | Read More |
