BS – INAUGURAL LECTURE
A roulette with curves and surfaces
Inaugural lecture of Professor Juhan Aru
If you need to choose between two equal options, you can toss a coin. If you need to choose between six of them, you roll a dice. If your life decisions have more facets, you can ask for help from a roulette. We all know what it means to uniformly randomly pick a number from one to ten, or to open the book from a random spot. But what does it mean to pick a random curve, or a random surface? How do such objects look like, are they beautiful? And why should we care about these random objects, why should we care, at all?
Juhan Aru was born in Estonia, has Bachelor and Master degrees in mathematics from University of Cambridge and a master's degree in interdisciplinary life sciences from Université Paris Descartes. He obtained his PhD in mathematics from ENS Lyon, and spent three years as a post-doc in ETH Zurich. In January 2019 he joined EPFL as a tenure-track assistant professor in mathematics.
He is interested in how to mathematically describe and study systems where geometric structure and randomness interact. The mathematical field studying such phenomena lies at the interface of probability theory, analysis and mathematical physics. More precisely, he studies random curves (SLE curves), height functions (Gaussian free field) and other random geometric structures (e.g. Gaussian multiplicative chaos), often with roots in the phenomena of statistical physics.
He has also done some work in neurosciences, written a mathematics book for high-school students and has taken part in constructing a computer-based statistics curriculum for high schools.
BS - HONORARY LECTURE
Engines of discovery
Honorary lecture of Professor Leonid Rivkin
After the first hundred years accelerators have come of age. These modern instruments of science and the associated technologies are at the heart of research that spans from the infinitely small to the infinitely large. Switzerland is host to two leading centers of accelerator science and technology, CERN and PSI. They belong to the handful of top scientific organizations with a worldwide impact that goes far beyond particle physics, and benefits all areas of natural sciences as well as industry. A brief overview of the recent achievements and of future developments will be presented.
Leonid Rivkin was born in Odessa in 1954. He studied physics in Novosibirsk and Cambridge, USA, graduating from Harvard University with AB in Physics in 1978. He completed is education with a PhD in Physics from Caltech in 1985. He worked on several accelerator projects at Stanford Linear Accelerator Center, followed by a year at LEP, CERN, Geneva.
He joined the Paul Scherrer Institute (PSI) in 1989 and worked on the design, construction and commissioning of the Swiss Light Source. Since 2006 he has been the Head of the Department of Large Research Facilities at PSI and professor of particle accelerator physics at EPFL. He has been serving as PSI Deputy Director since 2017. Currently serving on several international advisory committees and a Fellow of the American Physical Society.
Explorer la médecine de demain
L’exposition itinérante «A notre santé!» sillonne la Suisse romande jusqu’au 17 novembre.
Immersive et interactive, cette exposition propose au public de tester des outils de mesure de soi et d’expérimenter comment la médecine de demain pourra offrir un diagnostic, des traitements ou des recommandations de santé plus adaptés et personnalisés.
Le thème de la nutrition personnalisée est présenté avec le projet «Food & you» du professeur Marcel Salathé. Avec le projet «Mon génome & moi» du professeur Jacques Fellay, c’est la prise de décision après des tests génétiques qui est abordée.
«A notre santé!» est un projet réalisé par Bioscope, le Musée de la main, l’UNIL, le CHUV et les HUG.
