A 25-year-old time capsule with science predictions for 2025

Twenty-five years ago, Quirks & Quarks celebrated their 25th anniversary by travelling forward in time — to 2025 — to find out how science had changed in the years since. In this fictitious future, our present, Zargon the robot, wakes up a Bob McDonald clone from the year 2000 to speak with scientists about 25 years of science. It's a mindbending audio time-capsule with predictions that were oddly prescient, sometimes unsettling or wildly wrong.

How the invention of the book shaped humanity

If we weren't so used to having books, we would think of them as a "miracle." That's how historian Irene Vallego views what she says is humankind's greatest and most influential invention: the book. "With their help, humanity has undergone an extraordinary acceleration of history, development, and progress," she tells host Nahlah Ayed. Vallego has traced written texts back to their earliest origins and she's written a book of her own, Papyrus: The Invention of Books in the Ancient World.

Where to find 'critical hope' in hard times

In an era of political polarization and fatigue from ongoing crises, hope is critical. But it's not something you have; it's something you do, argues education scholar Kari Grain. "Critical hope" in action is not just the belief that transformation is possible — it's necessary. In her book, she explores seven principles for practicing hope that confront toxic positivity, social injustices, and gives anger and grief a seat at the table. Kari Grain is a professor at the University of British Columbia in the Faculty of Education, where she leads the Masters program in Adult Learning and Global Change Program. She delivered the University of Prince Edward Island’s 2025 Shannon K Murray Lecture on Hope and the Academy.

An apocalyptic retelling of the Christmas story

The nativity story that Christians believe is that God took the form of a baby named Jesus who was born to save the world and bring about an enduring peace. So what happened? Did we miss it? And what happens next? These are questions Trappist monk Thomas Merton grappled with in his own meditation on the Christmas story. His version "The Time of The End is the Time of No Room" was published in 1966. At the time he called it a sober statement about the climate of our time, a time of finality and fulfillment.

The 'dangerous' promise of a techno-utopian future

Tech billionaires are on a mission to make the stories of science fiction a reality: space colonization, human/machine bio organisms, and living forever in a state of unhindered bliss. This version of a far future utopia may come of as a "billionaire boys and their toys" but experts warn such a dismissive attitude is naïve and dangerous. *This episode originally aired on Jan. 22, 2025.

Jazz fan or not, you've probably heard this musician play

If you think you've never heard Jerry Granelli play drums — you likely have. Think of a comic strip holiday special and an iconic soundtrack: A Charlie Brown Christmas. Jerry was 22 years old when he became a member of the Vince Guaraldi Trio, the jazz band behind the popular 1965 album. His long career was legendary, accompanying many of the greats like Mose Alison, Sly Stone and The Grateful Dead. Producer Mary Lynk was lucky to meet with Jerry on the eve of his 80th birthday for a wide-ranging conversation. The gifted composer and jazz giant died in Halifax in 2021. *This episode originally aired on December 21, 2020.

How to change minds and find common ground

In 2024, 'polarization' was Merriam-Webster's word of the year. That division still grows, making it increasingly difficult to connect to one another. But there are people having important conversations and they have advice for us all. From fighting for LGBTQ+ rights in Colombia, championing human rights in Southern Africa and working for a two-state solution post Oct. 7, the winners of the The Global Centre for Pluralism awards tell host Nahlah Ayed about how minds can and do change, and why we need to not only talk, but listen.

Why spirituality is central to Indigenous mathematics

Indigenous math isn't just about numbers and equations, it involves culture, spirituality and more. Math professor Edward Doolittle, a Mohawk from Six Nations in Ontario, sees math as something embedded in Creation itself. In his Hagey Lecture at the University of Waterloo, he describes Indigenous mathematics as being grounded in cognition, emotion, the physical world and community. Indigenizing math, Doolittle hopes, will make it more approachable and meaningful to Indigenous students — show them how entwined it is with everyday life and something much bigger than ourselves.
