Public Lecture Series

Description: This panel format public talk will bring together experts in the history and philosophy of quantum theory and researchers working on various foundational issues to shed new light on the past, present, and future of the theory. 

Eventbrite/PION page links to come.

Off-site Public Lecture at Centre for International Governance Innovation (CIGI). Will run like PL at PI, Media Tech Services team and Sherwood working together for production. Volunteers are PI regular PL volunteers.

Stephen Hawking made a number of memorable contributions to physics, but perhaps his greatest was a puzzle: is information that falls into a black hole destroyed, in contradiction with the laws of quantum mechanics? The question sits squarely at the overlap of the quantum world and gravitation, a frontier of physics where direct experimental input is hard to come by. Recent progress has been revealing how subtle effects relate the radiation leaving a black hole to what happens inside. In this lecture, we will dive into the black hole information puzzle: what it is, what we have learned about it, and where it all might lead.

Battle of the Big Bang: The New Tales of Our Cosmic Origins

Abstract

The story of the universe’s origins is one of the greatest mysteries in science. From the explosive birth of the cosmos to the enigmatic nature of time and space, we are continually challenged by paradoxes that defy current understanding. In this public talk, we shall explore the triumphs and debates that shape modern cosmology, and the novel quests to uncover our cosmic origins. I will also highlight the pioneering contributions of my friend and colleague, Lee Smolin. His groundbreaking ideas on quantum gravity, the nature of time, and cosmological evolution have sparked new directions in the search for a deeper theory of the universe. Together, we will journey through the frontiers of physics, exploring how new theories and astronomical observations might offer clues to the next great paradigm shift. Whether you’re a science enthusiast or just curious about the cosmos, join us for a conversation on the past, present, and future of our understanding of the universe.

Niayesh Afshordi is a theoretical astrophysicist and professor at the University of Waterloo and Perimeter Institute for Theoretical Physics. His research explores the frontiers of cosmology, gravity, and quantum physics, with a focus on black holes and the origins of the universe. He is the co-author of the forthcoming popular science book Battle of the Big Bang: The New Tales of Our Cosmic Origins (University of Chicago Press, 2025), which reexamines the history and future of the cosmos through the lens of cutting-edge theory and observation.

Abstract

How do chemical reactions change when they’re run at temperatures a billion times colder than a Canadian winter? What can we learn when we have perfect quantum control of the reactants? Before answering these questions, we’ll discuss the fascinating techniques of laser cooling that allow us to cool atoms and molecules to within a few billionths of a degree above absolute zero. We’ll then look at how molecules prepared at such temperatures allow us to control chemical reactions at the quantum level, beginning to open a new understanding of chemistry and new possibilities for technologies of the future.

About the Speaker

Dr. Alan Jamison is an Assistant Professor at the University of Waterloo, jointly appointed to the Department of Physics and Astronomy and the Institute for Quantum Computing (IQC). He leads the Jamison Lab, which investigates ultracold atoms and molecules to explore quantum many-body physics, quantum chemistry, and quantum information science. Dr. Jamison earned his B.S. in Mathematics from the University of Central Florida in 2007, followed by an M.S. and Ph.D. in Physics from the University of Washington in 2008 and 2014, respectively.

After completing his Ph.D., he joined the group of Nobel Laureate Wolfgang Ketterle at the Massachusetts Institute of Technology (MIT) as a postdoctoral researcher. At the University of Waterloo, Dr. Jamison's research centers on using ultracold atoms and molecules to investigate complex quantum systems. His lab aims to achieve precise control over chemical reactions at ultracold temperatures, providing insights into quantum chemistry and enabling advancements in quantum computing and simulation.

Artificial Intelligence and big data are dramatically transforming the way we work, live and connect. Innovators have begun designing AI solutions to advance society at a rapid pace, but often new technologies bring both promise and risk. How can we trust AI and safeguard society from unintended consequences to ensure a safe and human-centred digital future?

Join the University of Waterloo in partnership with the Perimeter Institute for the TRuST Scholarly Network’s Conversations on lecture series where technology leaders from UWaterloo, Google and NASA will discuss how AI is transforming society and if we should trust these technologies.
