Quanta Science Podcast

Mathematicians have started to prepare for a profound shift in what it means to do math. This is the second episode of our new weekly series The Quanta Podcast, hosted by Quanta magazine Editor-in-Chief Samir Patel. This week’s guest is Jordana Cepelewicz; she recently published “Mathematical Beauty, Truth and Proof in the Age of AI” for Quanta’s AI special package. (If you’ve been a fan of Quanta Science Podcast, it will continue as ‘audio edition episodes’ in this same feed every other week.)

Certain grammatical rules never appear in any known language. By constructing artificial languages that have these rules, linguists can use neural networks to explore how people learn.

The brain's astounding cellular diversity and networked complexity could show how to make AI better.

he Quanta Podcast is your weekly dispatch from the frontiers of science and mathematics. In each episode, editor in chief Samir Patel will talk to the writers and editors behind our most popular, interesting and thought-provoking stories. The first episode of The Quanta Podcast will be live on May 20. In this trailer episode, Patel talks to executive editor Michael Moyer about what Quanta covers, how it has changed over time and our recent special series on “Science, Promise and Peril in the Age of AI.” Join us every Tuesday for stimulating conversations and insights about the biggest ideas in basic science and mathematics.
