Public Lecture Series

Jocelyn Bell Burnell, winner of the 2018 Special Breakthrough Prize in Fundamental Physics, is an accomplished scientist and champion for women in physics. As a graduate student in 1967, she co-discovered pulsars, a breakthrough widely considered one of the most important scientific advances of the 20th century. When the discovery of pulsars was recognized with the 1974 Nobel Prize in Physics, the award went to her graduate advisor. Undaunted, she persevered and became one of the most prominent researchers in her field and an advocate for women and other under-represented groups in physics.

She plans to use the $3 million Breakthrough Prize to fund women and other under-represented groups pursuing physics to bring greater diversity to the field.

Dr. Avery Broderick will provide a highly accessible and interesting lecture on the Event Horizon Telescope (EHT) and international efforts to interpret horizon-resolving images of numerous supermassive black holes. Black holes are among the most powerful and mysterious phenomena in the universe. Almost every galaxy has at its core a supermassive black hole, millions or even billions of times more massive than our sun. Despite composing a small fraction of the galactic mass budgets, they set the stage for astrophysical dramas that dictate the fates of their hosts. Though black holes are in theory the ultimate manifestation of strong gravity’s impact on the visible universe, placing these exotic phenomena on concrete empirical footing has been impossible - until now.

Can computers think? They can certainly calculate - with staggering speed and ever-increasing power - and they have driven scientific and technological advances that would have been impossible without them. Even so, we would like to believe that, for some puzzles, there's no substitute for old-fashioned human intuition. But this view may be changing.

A new breed of machine learning algorithms have begun knocking down cognitive milestones that, until recently, scientists believed were still decades away. Major advances are being made in computer vision, language translation, autonomous robotic action, and other complex applications. At the same time, these new algorithms are helping scientists accelerate discovery in physics.

This stunning progress poses as many questions as answers: What are the fundamental possibilities and limits of machine learning? Can we create true human-level artificial intelligence, and how might its thoughts differ from our own? What new breeds of computer will fuel artificial intelligence and, conversely, how will artificial intelligence enable new forms of computing?

In his public lecture at Perimeter Institute, Roger Melko will explore how computers have helped humanity solve increasingly complex puzzles, and ask which challenges, if any, only human intuition is equipped to tackle.

From the Stone Age to the Silicon Age, nothing has had a more profound influence on the world than our understanding of the materials around us. The Industrial Revolution of the 19th century and the Information Revolution of the 20th were fueled by humankind’s ability to understand, harness, and control materials.

Our ongoing quest to find and develop new kinds of materials, in hopes of tackling some of society’s most challenging energy problems, requires us to learn how to build materials from the atom up. Doing so means combining state-of-the-art technologies (such as growing thin-film materials) with cutting-edge techniques for probing the electron structure. Relatively recent advances in these fields have given researchers unprecedented understanding and insight into creating new materials with exotic and useful properties.

In his public lecture at Perimeter Institute, Rob Moore will explore how the next great “age” of humankind may well be forged in this new quantum world of materials.

How big can a star get? Why would a star only pretend to explode? Can you hide one star inside another?

Take a tour of some of the strangest stellar phenomena in the universe during this talk featuring Emily Levesque. From the biggest, brightest, and most volatile stars to the explosive fireworks of core-collapse supernovae and the fascinating physics of gravitational waves, "weird" stars serve as a common thread for exploring our universe's history, evolution, and extremes. Levesque will discuss the history of stellar astronomy, present-day observing techniques, and exciting new discoveries, and explore some of the most puzzling and bizarre objects being studied by astronomers today.

Science is like puzzle-solving. Making sense of quantum theory is a particularly thorny kind of brain-twister, with more than its fair share of mysteries. If you are stuck on a puzzle, it may be because you have made a false assumption about the nature of some entity that is absolutely central to the whole business. If so, you have made a category mistake: you are not just wrong about what this entity is, but about what sort of thing it is.

In his Public Lecture at Perimeter Institute, Robert Spekkens will explain why he believes that many quantum mysteries are a result of a category mistake concerning the nature of quantum states. Along the way, he will address some idiosyncratic questions, such as: What did Plato have to say about Heisenberg’s uncertainty principle? What do poorly implemented clinical drug trials have to do with "spooky action at a distance"? And, most importantly, what did the successful deciphering of Egyptian hieroglyphs teach us about the interpretation of quantum theory? 

Spekkens is a faculty member at Perimeter Institute whose research examines the foundations of quantum theory. He co-edited the book Quantum Theory: Informational Foundations and Foils, and he is a Project Leader of the international research collaboration "Quantum Causal Structures.” In 2012, he won first prize in the Foundational Questions Institute (FQXi) essay contest "Questioning the Foundations: Which of Our Assumptions Are Wrong?" He lives in Waterloo with his wife and three-year-old son.

As a child, Quebec native Pauline Gagnon dreamed of understanding what the universe was really made of.

As an adult, she studied exactly that, working at the largest experiment ever built, CERN’s Large Hadron Collider. In her role as a Senior Research Scientist, based at Indiana University and working at CERN, she searched for dark matter particles in the decays of the famous Higgs boson, in the form of hypothetical particles called dark photons.

Now retired from active research, Gagnon is dedicated to inspiring other curious minds of all ages to ponder the same big questions that fascinated her as a child. Having worked in the CERN Communications group, she is adept at explaining the complex science of particle physics in engaging, comprehensible ways. She has delivered nearly 100 presentations to audiences in nine countries on three continents.

Gagnon’s popular science book, Who Cares about Particle Physics: Making Sense of the Higgs boson, the LHC and CERN, not only explains current issues in particle physics but also explores the importance of fundamental physics in shaping not only our understanding of the universe, but in shaping society as well.

In her Perimeter Institute Public Lecture, Gagnon will explore the incredible (and improbable!) feats of ingenuity and cooperation that have led to one of humanity’s greatest experiments, and why such pioneering research, albeit “useless” in terms of everyday practicality, has changed the way we live and is vital to our collective future.

Are we standing on the brink of a new scientific revolution that will radically change our views on space, time, and gravity?

In most circumstances, the theories of Einstein and Newton adequately describe gravity, but on cosmological scales, big questions arise, particularly surrounding the nature of dark matter and dark energy.

These questions are ushering in a revolution in theoretical physics – a completely new view on spacetime and gravity. Research in string theory and black hole physics, involving key concepts of quantum information theory, reveals a deep connection between the structure of spacetime and the origin of gravity.

This research suggests that gravity is not a fundamental force of nature, but rather an emergent phenomenon, similar to how temperature is an emergent phenomenon that arises from the movement of particles. That is, gravity is a side-effect, not a cause, of what happens in the universe.

In his public lecture, Dr. Erik Verlinde (University of Amsterdam) will explore the core ideas behind this research, and examine the implications of this fast-emerging revolution in our understanding of the universe.

Join the original Captain Kirk, William Shatner, as he interviews renowned scientists and celebrities about the enduring influence of Star Trek on popular culture, innovation, and creativity.

THE TRUTH IS IN THE STARS chronicles Shatner’s journey around the world to discover how Star Trek’s optimistic vision for the future has inspired leading minds including Perimeter Institute Director Neil Turok, Perimeter Founder Mike Lazaridis, Prof. Stephen Hawking, Neil deGrasse Tyson, Chris Hadfield, David Suzuki, and many more.

More than a billion years ago, two black holes collided. In the final second of their long life together, the black holes banged out a rhythm like mallets on a drum, creating gravitational waves – ripples in the shape of spacetime. One hundred years ago, Albert Einstein predicted the existence of such waves, though it seemed improbable – if not outright impossible – that we’d ever be able to actually detect them. They were long considered too faint for any earthbound experiment to measure. Undaunted, experimentalists were determined to measure these Lilliputian ripples, and after many decades of work and collaboration, they built LIGO – the Laser Interferometer Gravitational-Wave Observatory. This incredible sophisticated and sensitive instrument was made to listen for the beat of that distant drum. In 2015, a billion years after the two black holes collided, their waves rippled through the LIGO detectors in Louisiana and Washington. With these remarkable new observatories, we can now capture the soundtrack to accompany the silent movie of the history of our universe.

Mathematics can be tasty! It’s a way of thinking, and not just about numbers. Through unexpectedly connected examples from music, juggling, and baking, Dr. Eugenia Cheng will demonstrate that math can be made fun and intriguing for all. Her interactive talk will feature hands-on activities, examples that everyone can relate to, and funny stories. She will present surprisingly high-level mathematics, including some advanced abstract algebra usually only seen by math majors and graduate students. There will be a distinct emphasis on edible examples.

The Hubble Space Telescope has completely revolutionized our understanding of the universe, and has become a beloved icon of popular culture. As revolutionary as Hubble has been, we have pushed it to its scientific limits in many ways. Hubble’s successor, the James Webb Space Telescope, has been in the works for almost two decades and is scheduled to launch in late 2018. It will be 100 times more powerful than Hubble. In her Perimeter Public Lecture, Dr. Amber Straughn will provide an update on the progress of building the world’s largest-yet space telescope, and will give an overview of the astronomical questions we hope to answer with Webb. These questions get to the heart of what it means to be human: Where did we come from? How did we get here? Are we alone?
