Neil Turok on the simplicity of nature
Neil Turok is a professor at the University of Edinburgh where he holds the Higgs Chair of Theoretical Physics. He acted as the director of Perimeter Institute from 2008 to 2019 and now holds the Carlo Fidani Roger Penrose Distinguished Visiting Research Chair in Theoretical Physics at PI. In this episode of Conversations at the Perimeter, he talks about his recent work that describes the Big Bang, how his research has been influenced by Stephen Hawking, and why he chooses to work on theories that have the potential to be proven wrong. He also talks about his time as director of Perimeter Institute and describes the strategies he used to create a culture and community capable of fostering breakthroughs. It's a fascinating conversation, and Neil is uniquely gifted in describing both the biggest questions in theoretical physics and the best strategies for answering them.

Sir Anthony Leggett on science, superfluidity, and serendipity
Sir Anthony Leggett, winner of the 2003 Nobel Prize in Physics for his foundational contributions to superfluidity, is a professor emeritus at the University of Illinois at Urbana-Champaign. Reflecting on a lifetime in science, he shares his groundbreaking work on superconductivity, superfluidity, and quantum science with Lauren and Colin, illuminating his ideas with simple metaphors of a military parade and children running in a forest. He also discusses the human connections that have shaped his life, from doing science demonstrations for families at a farmer’s market to his experiences in England, the US, Canada, Ghana, and more.

Shep Doeleman on hunting for black holes
Shep Doeleman is a senior research fellow at the Center for Astrophysics | Harvard & Smithsonian and one of the world’s leading experts on black holes. He heads the globe-spanning Event Horizon Telescope (EHT) collaboration, which in recent years unveiled humanity’s first-ever images of black holes – including the supermassive behemoth at the centre of our own Milky Way galaxy. Doeleman takes Lauren and Colin behind the scenes of the EHT’s discoveries, which earned the collaboration the prestigious Breakthrough Prize in Fundamental Physics in 2020. He also looks ahead to the next big milestones in black hole science, such as the Next-Generation EHT (ngEHT) and the Event Horizon Explorer, which will bring these mysterious phenomena into even sharper focus.

Shohini Ghose on revolutions – quantum and social
Shohini Ghose is a professor of quantum science at Wilfrid Laurier University. She is also the founder and director of Laurier’s Centre for Women in Science (WinS) and an NSERC Chair for Women in Science and Engineering. In this episode, she takes Lauren and Colin on a journey into the subatomic realm to explore concepts like entanglement, superposition, and her personal favourite quantum quandary: uncertainty. She explains how ideas in quantum science can translate to questions of identity, and how that drives her efforts to improve equity and diversity in science. She also thoughtfully answers questions submitted by elementary school students, and provides a sneak peek into the topics of her upcoming book. Learn more about the her work in equity and diversity with these online resources from WinS: laurierwins.medium.com. View the episode transcript here.

Pedro Vieira on a theory of all quantum field theories
Pedro Vieira is a faculty member at Perimeter Institute, where he holds the Clay Riddell Paul Dirac Chair in Theoretical Physics. In this episode, he tells Lauren and Colin about his work on a kind of uber-theory that encompasses all quantum field theories, as well as what separates the easy and hard problems in this field. It’s a complicated topic to be sure, but Vieira is a master of explaining complex topics with relatable examples and anecdotes – something Lauren discovered as a student when she took a course he taught. “Pedro takes some of those same concepts from graduate courses, but he paints some amazing non-technical pictures for us,” says Lauren. “No mathematical background required!” He explains why the universe might be a hologram and why, from a theoretical physics perspective, a messy bedroom can be a good thing.

Ganapathy Baskaran on physics, biology, and global science
Ganapathy Baskaran is an acclaimed physicist known for his foundational contributions to condensed matter physics, strongly correlated quantum materials, and high-temperature superconductivity. He is an Emeritus Professor at the Institute of Mathematical Sciences in Chennai, India, and a Distinguished Visiting Research Chair at Perimeter. He is also a masterful storyteller who, in this episode, tells Lauren and Colin about his upbringing in India, the people who inspire him, and his time in the developing world. Baskaran reflects on a lifetime of exploring some of nature’s most fundamental mysteries, and discusses the similarities and differences that he sees between condensed matter physics and biology.

Savarimuthu, and his English teacher, Rev. Fr. K.S. Arulanandam, S.J. Baskaran also reached out after our recorded conversation to extend his thanks to others who have impacted his career, including Dr. Rajaram Nityananda, a contemporary graduate student (from National Aeronautical Laboratory, Bangalore) during his PhD days in Bangalore. “Rajaram is one of the most selfless persons I have ever met,” says Baskaran. It was Rajaram who introduced Baskaran to seminal work by P.W. Anderson, a later collaborator of Baskaran’s. “In 1977, H.R. Krishnamurthy arrived from Cornell and explained to us the intricacies of the Kondo phenomenon, valence fluctuation, and how to understand them using the quantum RG approach (built on Anderson’s poor man’s scaling theory) that Krishnamurthy, Wilkinson, and Wilson had just developed. Anderson’s masterly role in modern condensed matter physics was manifest. Strong correlation physics, including Mott insulators, was in the air,” Baskaran says. Later in his career, Baskaran worked with professors who played a “lifting role” in his life, including R. Rajaraman, G. Rajasekaran, and Erio Tosatti. “I am thankful to my school, college, teachers, friends, my family, my mom Leelavathy, my dad Ganapathy, siblings, uncles, aunts, cousins, nephews, my wife Whiterose, my children, their spouses, and my grandchildren.”

Dustin Lang on big data from a big universe
Dustin Lang is a computational scientist at Perimeter Institute who develops techniques for finding needles in the cosmic haystack. He works on several large sky survey projects, tackling the statistical data analysis required to discern meaningful insights from huge datasets gathered by telescopes. In this conversation with Lauren and Colin, he shares his experiences mapping galaxies with the Dark Energy Spectroscopic Instrument (DESI), and hunting for mysterious fast radio bursts (FRBs) with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). He explains how he and his colleagues employ software solutions to expand capabilities of hardware telescopes, the challenges he has encountered in radio versus optical astronomy, and the important role of chicken wire at CHIME.
