Think of science's most momentous developments in the 20th century — Einstein’s theory of relativity, quantum physics, finding evidence of black holes. If you trace the chain of discoveries that led to these breakthroughs back far enough, you’ll end up with the Italian astronomer and physicist Galileo Galilei. Theoretical physicist Carlo Rovelli says we can learn a lot from Galileo today. He explains how 400 years ago, the renowned inventor was discovering new facts about the Universe to understand ourselves better — and so are we.

"This is a hopeless situation but we are not helpless." This is what drives Sudanese journalist Yousra Elbagir's reporting on her homeland's forgotten war. She uses what she calls "human reporting" to let the world know Sudan is more than conflict and suffering. "Sudanese generosity is our lifeblood. That's what's keeping us alive right now. We are actually surviving in forced starvation through generosity and kindness and care."Yousra Elbagir delivered the 2025 Stursberg Foreign Correspondents Lecture at Carleton University. She spoke to host Nahlah Ayed about her work and her lecture: Human reporting from Sudan and beyond — a remedy for selective empathy?

"Those who remember the disappeared would also disappear." Under dictator Bashar al-Assad, grieving publicly in Syria was punishable. Now the silenced stories of lost loved ones are emerging and there are public spaces to grieve. Syrian architect Ammar Azzouz's friend and colleague Taher Al Sebai was killed on his street in 2011. After 14 years in exile, Azzouz returned home and says it's not just a right but "a duty to remember."

Prior to riding horses, no one wore pants. There's a lot to thank horses for in our daily lives. From the Hollywood motion picture to life-saving vaccines for diphtheria and tetanus. Historian Timothy Winegard argues horses are intertwined in our own history to the point that we overlook their importance. His research explains how they shaped societies, economies and cultures. Without us, horses would be nowhere, and vice versa. It was a partnership — our brains and their braun — that truly changed the world. *This episode originally aired on Sept. 10, 2024.

It's getting pretty difficult to read any article online without a paywall in the way. What happened to the internet's great promise to democratize knowledge? On an individual basis, artists, writers and scientists can create without fear of theft thanks to copyright laws. But in practice copyright laws set up barriers, stifle production and prevent equal access to art and research. In this podcast, producer Naheed Mustafa explores the fate of “open access” — all in the ever-expanding universe of copyright laws, paywalls and old-fashioned bureaucratic sludge.Guests in this podcast:John Willinsky is emeritus professor of education at Stanford University with an appointment at Simon Fraser University.Lokesh Vyas is pursuing a PhD at Sciences Po in Paris working on the history of international copyright law.Thea Lim is a Toronto-based novelist, creative writing teacher, and cultural writer focussing on the intersection of power, art and personhood, and technology.
