    The 33,000 Horsepower Gamechanger | The Greatest Numbers of All Time
    There is nothing random about featuring 33,000 in our number series. It's very powerful. So much so, that the number put millions of horses out of work. Inventor James Watt used “33,000 foot-pounds a minute" to measure the capabilities of a horse when trying to market his new and improved steam engine. The engine was a big success, saving horses from the drudgery of manual labour. Now, a similar process is underway with artificial intelligence — but are we the horses, or the steam engine? *This episode is part of our series, The Greatest Numbers of All Time.For more in the series:Listen to The Curse of 13Listen to 12 is SublimeListen to 27 Club LoreListen to How 4 Makes and Breaks RulesGuest in this episode:Stephanie Dick is a historian of mathematics, technology, computing, and AI, and an assistant professor at Simon Fraser University.

    27 Club Lore | The Greatest Numbers of All Time
    Twenty-seven can be a pivotal and tumultuous age. It’s held up as the year of peak performance in many sports and it's also seen as a cursed age for pop and rock stars, exemplified by the so-called 27 Club. Artists like Jimi Hendrix, Janis Joplin, Kurt Cobain and Amy Winehouse, all died at 27. As part of our series, The Greatest Numbers of All Time, IDEAS producer Chris Wodskou makes the case for a number that may not stick out in your mind but is more significant than you think.More episodes in this series:Listen to 12 is SublimeListen to The Curse of 13Listen to The 33,000 Horsepower GamechangerListen to How 4 Makes and Breaks RulesGuests in this podcast:David Awosoga is a PhD student in Statistics at University of Waterloo and sports performance data analyst.Alan Cross is a music historian, broadcaster, and host of The Ongoing History of New Music podcastDianna Kenny is a professor emerita of psychology and music at University of Sydney and psychotherapist in private practice.Michael Owen is a retired clinical psychologist and author of The 27 Club.Maria Westerstahl is senior lecturer at Karolinska Institutet in Sweden.

    12 is Sublime | The Greatest Numbers of All Time
    Complete. Whole. Divine order. That's just the start of what makes the humble dozen extraordinary. It's one of only two numbers ever discovered in mathematics to be “sublime.” Twelve makes a number of appearances in pop culture, in religion, in non-fiction, everything from the 12 days of Christmas to the 12 people it takes to form a criminal jury. Still need convincing of 12’s perfection and indispensability? Check your watch.More episodes in our series, The Greatest Numbers of All Time:Listen to The Curse of 13Listen to 27 Club LoreListen to The 33,000 Horsepower GamechangerListen to How 4 Makes and Breaks RulesGuests in this episode:Glen Van Brummelen is a professor of mathematical sciences at Trinity Western University.Ainsley Hawthorn is a cultural historian and nonfiction writer.

    The Curse of 13 | The Greatest Numbers of All Time

We've just blindly accepted its bad reputation. As part of our series, The Greatest Numbers of All Time, IDEAS explores where our irrational fear and uncomfortable feelings about 13 began. *All five episodes in our number series will be available daily in our feed this week.*Listen to 12 is SublimeListen to 27 Club LoreListen to The 33,000 Horsepower GamechangerListen to How 4 Makes and Breaks RulesGuests in this episode:Stephen Winick is a folk life specialist at the American Folklife Center of the Library of Congress.Barry Markovsky is distinguished professor emeritus of sociology at University of South Carolina.
