Title : The History of Gravitational Lensing in Cosmology Abstract : In this talk I review the development of gravitational lensing in cosmology - a subject which is entering a "golden age" with the advent of Euclid and LSST. I start with Newton, who, it seems, understood light deflection but didn'...more

Title: The ubiquity of logarithmically correlated fields and their extremes. Abstract : Logarithmically correlated fields (LCF) are random fields that exhibit a certain type of long range correlation. In the last two decades, they were shown to pop up in a variety of models, such as certain PDE's,...more

Abstract: Stochastic phase space cooling using microwave techniques in the GHz frequency range have been employed historically in particle colliders, leading to ground-breaking discoveries. ‘Cooling’ increases the likelihood of observing rare physics events. The first important advance --...more

Abstract: G protein-coupled receptors (GPCRs) detect molecules outside the cell (say Morphine) to open the G protein (GP) bound inside the cell to release a GDP that exchanges with GTP to signal a response inside the cell (relieves pain in this case). GPCR agonists include odors, tastants,...more

Abstract: It is nearly twenty years since one atomic layer of carbon, which we call graphene, was separated from graphite and shown that it could lead to a new generation of electronic field-effect transistors. Prof. Arindam Ghosh will talk about how the unique fundamental physics of graphene and...more

Giorgio Parisi is an Italian theoretical physicist, whose research has focused on quantum field theory, statistical mechanics and complex systems. His best known contributions are the QCD evolution equations for parton densities, obtained with Guido Altarelli, known as the Altarelli–Parisi or DGLAP...more

Abstract: As Sir Charles Frank said "Physics is not just Concerning the Nature of Things, But Concerning the Interconnectedness of all the Natures of Things”, which encapsulates an overarching theme of the 2021 Prize. I provide a scientific overview of this year’s prize, colored partly by my role...more

Abstract: In this talk I will focus on describing, in a qualitative way, the reason statistical mechanics is able to predict, with great certainty, behavior of macroscopic systems, both in equilibrium and out of it. I will relate this to the fact that this behaviour is typical for systems...more

In this talk, aimed at non-specialists, I’ll describe the geometric questions in the 19th century that led to the geometric theory of residual intersections, from oddities such as “How many conics in the plane are tangent to 5 given conics?” to central topics such as the Riemann-Roch theorem and...more

The quest for efficient algorithms is central both to theoretical computer science and to the practice of computing, but the metrics used in the two areas are different: theoreticians usually evaluate algorithms by their worst-case performance, whereas practitioners are more interested in empirical...more
