Generally, dark energy and dark matter are regarded as separate entities, but recent astronomical observations have spurred scientists to look further into a less widespread idea — that the two are in fact physically intertwined. On this episode of The Quanta Podcast, host Samir Patel speaks with Physics Editor Kathryn Jepsen about the theories surrounding dark energy’s ties to dark matter and the possibility of a shared dark universe.

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.

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.

McConnell called Cannibals, Chemicals and Memory, where he describes how his experimental work led to the conclusion that flatworms can learn. Audio coda credit: The Drs. Nicholas and Dorothy Cummings Center for the History of Psychology, The University of Akron, Ohio.
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.

Amid the chaos of revolutionary France, one man’s mathematical obsession gave way to a calculation that now underpins much of mathematics and physics. The calculation, called the Fourier transform, decomposes any function into its parts. The story What Is the Fourier Transform? first appeared on 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.
