Avi Wigderson, Ph.D.Princeton University
Presidential Lectures are a series of free public colloquia spotlighting groundbreaking research across four themes: neuroscience and autism science, physics, biology, and mathematics and computer science. These curated, high-level scientific talks feature leading scientists and mathematicians and are designed to foster discussion and drive discovery within the New York City research community. We invite those interested in these topics to join us for this weekly lecture series.
Is the universe inherently deterministic or probabilistic? Perhaps more importantly — can we tell the difference between the two?
Humanity has pondered the meaning and utility of randomness for millennia. There is a remarkable variety of ways in which we utilize perfect coin tosses to our advantage: in statistics, cryptography, game theory, algorithms, gambling and more. Indeed, randomness seems indispensable! Which of these applications survive if the universe had no randomness in it at all? Which of them survive if only poor quality randomness is available, e.g. that arises from “unpredictable” phenomena like the weather or the stock market?
A computational theory of randomness, developed in the past three decades, reveals (perhaps counterintuitively) that very little is lost in such deterministic or weakly random worlds. In this talk, Dr. Wigderson will explain the main ideas and results of this theory.
About the Speaker
Avi Wigderson has been a professor in the School of Mathematics at the Institute for Advanced Study since 1999. There, he leads the Institute’s Computer Science and Discrete Math Program and works in the theory of computation, a field which studies the mathematical foundations of computer science. He is interested in algorithms, Boolean and arithmetic circuit complexity, communication and proof complexity, cryptography, randomness, as well as the interactions of the field with other sciences including mathematics, physics, biology and economics.
