How to develop 'in the zone' hyper focus

You've likely experienced it: that state of being in the groove, on a roll, lost in the process. It's what researchers call 'flow': a state intimately familiar to athletes and artists — or anyone who's been fully absorbed in a given task to the point where time seems to stand still. In this state there's a sense of self disappearing, presenting a paradox between a state in which you lose yourself, yet become yourself. Writer and triathlete, Suzanne Zelazo, delves into the mystery at the heart of flow in this documentary. *This episode originally aired on June 25, 2021.

How a natural catastrophe 8,000 years ago may have fueled Brexit

For the first two billion years, the Earth didn't have oxygen. That's just one of the many fascinating details Peter Frankopan reveals in his book, Earth Transformed: An Untold History. The Oxford professor of global history takes us on a multi-million year tour, illustrating the breathtaking ways climate has shaped the Earth and human civilization. How the collapse of a sediment shelf 8,000 years ago isolated what's now Britain from Europe, and its potential influence on the Brexit vote in 2016. Or how climate fluctuations correlate to periods of antisemitic violence. There's a lot to learn in this podcast. Have a listen.

How Britain caused Ireland's Great Famine

The potato and the Irish Famine of 1845 will forever be linked. But what's often overlooked is how deeply connected the potato was to British colonial policies during that time. To Britain it was a symbol of Irish backwardness. In the book Rot, a new history of Ireland's Great Famine is revealed, showing how the British Empire caused the infamous disaster. Author and historian Padraic X Scanlan paints a complex and compelling picture of the Irish Famine of 1845, in which the potato — and the blight — played but a part in a broader story of colonialism, capitalism, and collapse.

When words get in the way, vocal improv saves the day

Would you 'doo-be-doo' if you know it would help bridge divides? Try vocal improvisation — singing sounds, rhythms and melodies. PhD candidate Erwan Noblet teaches the practice and says it's a great way to open up and connect at another level being together. He believes the human voice has the power to communicate creatively when it's released from everyday verbal tasks. We asked three former politicians from different political parties to communicate through vocalization, without words. Their conversation may inspire you to take on vocal improv. *This episode is part of our ongoing series Ideas in the Trenches, which showcases fascinating new work by Canadian PhD students.

Following the wisdom of water to remake an unravelling world

Water has been "a powerful teacher" for Nishnaabeg scholar Leanne Betasamosake Simpson, a member of Alderville First Nation north of Lake Ontario. With so much uncertainty about the kind of world that’s taking shape, her award-winning book Theory of Water draws on Anishinaabe creation story, Indigenous ethics of relationality and reciprocity, and the wisdom of water to chart a course for remaking a better, more sustainable and just world. Simpson's Theory of Water: Nishnaabe Maps to the Times Ahead won the Hilary Weston Writers’ Trust Prize for Non-Fiction in 2025.

Why the Monroe Doctrine has world leaders on edge

Firstly, you might ask: What is the Monroe Doctrine? It's a U.S. policy created in the 19th century that opposes foreign interference in the affairs of the "Western Hemisphere." It was understood to be a defense of autonomy but its interpretation is mixed. Various presidents over time have used the doctrine for their own purposes, writing their own political agenda onto it. Now is no different, as Donald Trump's government turns to the policy as a way to control the Western Hemisphere. Guests in this episode: Richard Drake is the Lucile Speer Research Chair in politics and history at the University of Montana Max Cameron teaches in the department of political science at the University of British Columbia and is president of the Latin American Studies Association
