About Simons Foundation Lectures

Simons Foundation Lectures are free public colloquia related to basic science and mathematics. These high-level talks are intended for professors, students, postdocs and business professionals, but interested people from the metropolitan area are welcome as well.

Quantum mechanics and general relativity are the two pillars of 20th-century physics. However, paradoxes arise when we attempt to combine these theories to arrive at a quantum theory of space and time, often because the appearance of black holes and spacetime singularities seem to destroy quantum information.

In this lecture, Vijay Balasubramanian will discuss how we can resolve these paradoxes by drawing on concepts of complexity and information from theoretical computer science, communications theory and cryptography. He will use techniques from these fields to explain diverse, interlinked aspects of fundamental physics, including: the dynamics of quantum chaos and thermalization; the recovery of information from beyond the horizon of black holes; and, most fundamentally, causality in physical processes.

To attend this in-person event, you will need to register in advance and provide:

  • Acceptable proof of vaccination (vaccine card/certificate, a copy or photo of vaccine card/certificate or electronic NYS Excelsior Pass or NJ Docket Pass)
  • Photo ID
  • Eventbrite ticket confirmation email with QR code
  • Simons Foundation Health Screening Questionnaire approval email

Guests are expected to complete these requirements each time they visit the Simons Foundation and entrance will not be granted without this documentation.

On-site registration will not be permitted. Walk-in entry will be denied.

About the Speaker

Balasubramanian is the Cathy and Marc Lasry professor of physics at the University of Pennsylvania. He received B.Sc. and M.Sc. degrees in physics and computer science from MIT and a Ph.D. in physics from Princeton University. He was a junior fellow of the Harvard Society of Fellows before joining the faculty at Penn. His research spans diverse fields ranging from string theory to theoretical neuroscience.
