CARLO ROVELLI: SEVEN BRIEF LESSONS ON PHYSICS
Think of some of the 20th Century science's most momentous developments — 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, physicist and inventor, Galileo Galilei. Renowned Italian physicist Carlo Rovelli, author of best-selling books like Seven Brief Lessons on Physics, explains how Galileo's discoveries and insights revolutionized science and helped usher in modernity — and how we can still learn a lot from him today.

WALKING AMONG THE ANCIENTS: THE WABANAKI-ACADIAN OLD GROWTH FOREST
To walk in an old growth forest is to be stunned by its untouched beauty, its otherworldliness — soaring ancient trees above, rolling thick ground underfoot, and astounding biodiversity all around. (Scientists are even researching its compound-rich air, for a potential role in preventing and treating cancer.) The Wabanaki-Acadian Forest, which stretches from parts of the Maritimes and Southern Quebec down into several New England states, is comprised largely of newer forests, already cut down and logged, over and over. Just one per cent of its old growth is left, and the World Wildlife Fund lists it as endangered. On this episode, accompany IDEAS to a secret old growth forest stand in Nova Scotia, to learn of its many wonders. *This episode originally aired on June 11, 2024.

PUTTING PRIDE ABOVE SHAME: LOVING YOUR COUNTRY IN THE 21st CENTURY (STEP THREE)
The first step to developing a healthy level of patriotism is to decide which country you in fact belong to. The second step is to understand what duties accompany that choice. Having taken those steps, a person can tackle what may be the toughest one, depending on the nationality in question: feeling proud. An ashamed patriot is theoretically possible, and to feel zero shame may be unhealthy as well as unlikely, but for countries to thrive and strive to be their best selves, their citizens must collectively find a sweet spot where positive feelings outweigh negative ones, just individuals need enough self-respect to overcome their inner demons. IDEAS producer Tom Howell gathers insights from Afghans, Israelis, and Americans in hopes of finding the key to doing patriotism right.

IDEAS FROM THE TRENCHES: THE CONSPIRACY PRACTICE
Growing up, PhD student Sarah believed in the literal interpretation of the Bible. Born into a devout evangelical Christian community, she fully espoused creationism and the historical existence of Noah's ark, and she predicted that non-believers faced a doom in hell upon Judgment Day. She's now estranged from her family, but draws on her evangelical past to understand the visceral belief people acquire in conspiracy theories — from PizzaGate to the 'stolen' 2020 US election. *This episode is part of our ongoing series, IDEAS from the Trenches. It originally aired on Sept. 21, 2022.

THE RADICAL POSSIBILITIES OF RETURN
What kinds of return are possible when you can't return home? Author of A History of Burning, novelist Janika Oza looks at the ways in which the narrative arcs of ordinary lives are shaped by ruptures like colonialism, war, and the Partition of India — and what it means to continually seek to return through stories, memories and objects. The Radical Possibilities of Return — the fourth in a series this season from Crow's Theatre in Toronto.

EXPOSING CRIME AND CORRUPTION IN THE WORLD: ICIJ DIRECTOR GERALD RYLE
It's estimated that a significant percentage of the world's wealth is held in secret offshore accounts — between $21 and $32 trillion. How much of the world's wealth is ferreted away is hard to know. However in the past decade billions of these hidden stashes have been uncovered through the thorough work of the International Consortium of Investigative Journalists (ICIJ). The ICIJ retains a network of more than 290 of the top investigative journalists around the work. Some of its major investigations include Offshore Leaks, Panama Papers, Paradise Papers, and Pandora Papers. These revealed the secrets of the rich and powerful and led to multiple arrests and official inquiries in more than 70 countries, and the resignations of the leaders of Pakistan, Iceland, and Malta. For the 2025 Dalton Camp Series, ICIJ Director Gerard Ryle is in conversation with IDEAS Host Nahlah Ayed.
Wednesday, April 9
RE-IMAGINING THE BORDER
A German, a Canadian, and an American walk onto the stage of the Centre Mont-Royal in Montréal, and try to agree on what's happening to the concept of a national border. They then set their imaginations to the task of picturing what borders should become, before the century is out. These conversants are Peter Altmaier, the German cabinet minister who ran his country's response to the 2015 "refugee crisis;" Julian Castro, U.S. secretary for housing under Barack Obama and current head of the U.S. Latino Community Foundation; and Ayelet Shachar, Canadian professor and author of The Shifting Border and The Birthright Lottery. IDEAS host Nahlah Ayed poses the questions.

TIMOTHY SNYDER ON FREEDOM
Historian Timothy Snyder (On Tyranny) speaks to Nahlah Ayed about his newest book, On Freedom. In a political era where the word freedom is defined and redefined by whichever faction needs to evoke it, Snyder argues that — more than the freedom from various things — we actually need the freedom to thrive, for the sake of our common future. Recorded in front of an audience at the Toronto Reference Library.

PROFESSORS' PATRIOTISM QUESTIONNAIRE
The intellectual class is reputed to feel squeamish about expressing patriotism. But time are a-changing. IDEAS producer Tom Howell attempts to pin down leading Canadian scholars on the extent to which their hearts swell with national pride, by subjecting each of them to a list of five questions aimed at both complicating and simplifying what they believe such professions of patriotism to mean.

AUTHOR BRETT POPPLEWELL ON SUPERAGING
Brett Popplewell chronicled the life of an octogenarian athlete for his 2024 Edna Staebler Award-winning book, Outsider. Dag Abaye rejects mainstream views of the aging body, and chooses to live alone in an old schoolbus in the mountains of B.C., challenging himself to run long distances each day. In this public talk, Brett Popplewell considers what he learned from his subject, and about pushing society's limits around aging.
IDEAS FOR A BETTER CANADA
We live in an era of eroding democracy where polarization is increasingly fracturing our sense of a shared reality. With another federal election approaching, there's a growing sense that our political system prioritizes short-term gains over the long-term health of our democracy. To address this, IDEAS hosted cross-Canada discussions to focus on local solutions with the potential to inspire national change. The series is part of CBC Collab fund and in partnership with the Samara Centre for Democracy.

IDEAS FOR A BETTER CANADA — PEI
In an ideal democracy, every citizen has a voice. Critics of Canada's first-past-the-post electoral system have long decried what they say is unfair representation in our halls of power. And for that and other reasons, voters are increasingly disengaged. As residents of Confederation's birthplace, Prince Edward Islanders have thought hard about the democratic exercise, engaging its citizens, and what can be done to reinvigorate our democracy. IDEAS host Nahlah Ayed hears from Prince Edward Islanders about how to can get the most out of our electoral system.

IDEAS FOR A BETTER CANADA — BURLINGTON
YOUR LIBRARY IS OPEN (AND BELIEVES IN DEMOCRACY)
Libraries are a target in the culture wars raging across the continent. Yet they exist to give everyone access to a wide variety of expressive content: even when those books, events, and materials may offend others. As upholders of the sometimes unpopular concept of intellectual freedom, can inclusive yet open library guidelines help remind us what democracy upholds? IDEAS host Nahlah Ayed visits Burlington Public Library in Ontario, to speak with local librarians, author Ira Wells (On Book Banning), and a community audience, about what can be learned from our libraries.

IDEAS FOR A BETTER CANADA — EDMONTON
WHY CAN'T WE BE FRIENDS?
In a politically polarized world, conversation across divides can go one of three ways: screaming from our silos, retreating into them, or patiently building bridges between them to allow for civil debate. From fostering deep empathy to role-playing games to re-defining community, we explore how to nurture healthier democracies by encouraging conversation. IDEAS host Nahlah Ayed hears from Edmontonians about how they make it work.

IDEAS FOR A BETTER CANADA — NANAIMO
Housing affordability is reaching a crisis point across Canada. The affordability crisis brings debate to local communities, stokes conflict, between generations, and contributes to a crisis of homelessness. IDEAS host Nahlah Ayed visits Nanaimo, British Columbia to ask: What does it mean for society when owning or renting your own home is out of reach for so many? How do you build a community when it's so hard to find a home near work, schools, and social lives? What obligations does a society have to ensure safe and stable housing is accessible to everyone?

A HISTORY OF HUMAN SHIELDS
The use of human shields is likely as old as war itself. In contemporary times we often see the use of involuntary human shields in war and conflict by both regular armies and militias — a practice forbidden under international humanitarian law. But there is also a long history of people voluntarily putting their lives at risk as a way to protect and show solidarity with a person or ideal or to lay bare a difficult political or social reality. Depending on the circumstances, choosing to use one's own body as a form of protection might be celebrated or reviled. In this episode, we take a look at the history of human shields and how they've been used both as a weapon of war and a weapon of peace.

MARTHA BAILLIE ON GRIEF (WRITER'S TRUST)
The death of a family member can stir up both fond and bitter memories and a complicated stew of conflicting feelings — grief, loss, resentment, guilt, bewilderment, solace. In her memoir, There Is No Blue, acclaimed Canadian writer Martha Baillie probes the meanings and mysteries of death and family relationships through contemplations of three losses — her 99-year-old mother; her father; and her sister who suffered from schizophrenia and died by suicide shortly after her mother's death. There Is No Blue was the 2024 winner of the Hilary Weston Writers' Trust Award for Nonfiction.

SILENCE AND MEMORY: LILIA TOPOUZOVA
During the Communist era in Bulgaria there was little room for political dissent. Protesters or anyone who opposed the government could be arrested, sent to the Gulag, and silenced. For 20 years Lilia Topouzova has been collecting the stories of those who survived: some had many stories, some had little to say, some had nothing to say — or just no way of saying it. From these stories she has recreated a Bulgarian room from the Communist era, where her meetings and conversations with survivors can be heard, a space about the absence of memory and what that does to a people, a space to bear witness to those who were sent to the camps, but who were everyone's friends, relatives…neighbours. The installation 'The Neighbours' is the official Bulgarian entry to the 2024 Venice Biennale.
