In 1992, mathematicians Dave Bayer and Persi Diaconis proved that seven riffle shuffles are enough to shuffle a deck of cards — but only if you can cut your deck with precision. Decades later, a new proof has finally extended the finding to less precise cuts. On this episode of The Quanta Podcast, host Samir Patel speaks with math editor Jordana Cepelewicz about how a mathematical cutoff phenomenon still exists for riffle shuffling — randomness seems to happen all at once.

This topic was covered in a recent story for Quanta Magazine.  

Each week on The Quanta Podcast, Quanta Magazine editor in chief Samir Patel and Senior Editor Hannah Waters speak with the people behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math.

In "The Best (and Worst) Ways to Shuffle Cards" from the YouTube channel Numberphile, Persi Diaconis demonstrates different kinds of shuffles, why you might want to stick with a classic riffle shuffle instead of what is called the overhand method and explains his seven shuffles result: https://youtu.be/AxJubaijQbI?si=WctYYRtCZVupMldO

Volcano forecasting can save countless lives. But most of the time warnings are more like educated guesses. How close are we to forecasting volcano behavior the way we forecast the weather? On this episode of The Quanta Podcast, host Hannah Waters speaks with writer and volcano expert Robin George Andrews about just how close we are to accurately forecasting volcanic eruptions.

In the 60s, an eccentric behavioral psychologist pureed a bunch of planarian worms and fed them to other ones. For years after, he claimed that the cannibal worms learned the ground-up worms’ memories. Could he have been… right? On this episode of The Quanta Podcast, host Samir Patel and columnist Claire L. Evans discuss the weird history of memory transfer experiments, and their recent resurgence — and some them appear to be working.  This topic was covered in a recent story for Quanta Magazine.

How many pieces are there in the Standard Model of particle physics? 17, 30, 37, 61, 118? Or is the true answer much larger — and not even an integer? It depends on your taste for complexity — and mystery. On this episode of The Quanta Podcast, host Samir Patel and columnist Natalie Wolchover plummet down another rabbit hole, and this one goes down to the very building blocks of our reality. This topic was covered in a recent story for Quanta Magazine.

The groundbreaking proof assistant Lean acts as a sort of automatic quality control. It’s gaining ground in the math world — in part because it can interact with AI to open new avenues of inquiry. But there are concerns, too. On this episode of The Quanta Podcast, host Samir Patel speaks with author Kevin Harnett about his new book, the first release from Quanta Books, “The Proof in the Code.” It was featured in a recent excerpt for Quanta Magazine.
