When ChatGPT Broke an Entire Field Jul 29, 2025

Show notes

The study of natural language processing, or NLP, dates back to the 1940s. It gave Stephen Hawking a voice, Siri a brain and social media companies another way to target us with ads. In less than five years, large language models broke NLP and made it anew.

In 2019, Quanta reported on a then-groundbreaking NLP system called BERT without once using the phrase “large language model.” A mere five and a half years later, LLMs are everywhere, igniting discovery, disruption and debate in whatever scientific community they touch. But the one they touched first — for better, worse and everything in between — was natural language processing. What did that impact feel like to the people experiencing it firsthand?
Recently, John Pavlus interviewed 19 current and former NLP researchers to tell that story. In this episode, Pavlus speaks with host and Quanta editor in chief Samir Patel about this oral history of “When ChatGPT Broke an Entire Field.”

Is Mathematics Mostly Chaos or Mostly Order? Jul 22, 2025

Show notes

As weird as it sounds, infinity comes in many shapes and sizes. And attempting to quantify it is sort of like a dog chasing its own tail. Or like infinities chasing infinities infinite numbers of times. But some mathematicians are obsessed with the quest.
In this episode, host Samir Patel and 𝘘𝘶𝘢𝘯𝘵𝘢 math editor Jordana Cepelewicz probe the bizarre edges of the mathematical universe, a realm *almost* impossible to put into words. This topic was covered by Greg Barber in a recent story for Quanta Magazine.

When Did Nature Burst Into Vivid Color? Jul 15, 2025

Show notes

Colorful messages are constantly being exchanged across the natural world, to communicate everything from sexual attraction to self defense. But which came first: these evocative signals or the sophisticated vision needed to see them? In this episode, host Samir Patel speaks with contributing writer Molly Herring about free diving, mantis shrimp, and the challenges of tracking coloration through evolutionary history. This topic was covered in a recent story for Quanta Magazine.

Is Gravity Just Rising Entropy? Jul 08, 2025

Show notes

Where does gravity come from? In both general relativity and quantum mechanics, this question is a big problem. One controversial theory proposes that the force arises from the universe's tendency toward disorder, or entropy. In this episode, host Samir Patel speaks with contributing writer George Musser about the long-shot idea called "entropic gravity," which Musser covered in a recent story for Quanta Magazine.

How Amateurs Solved a Major Computer Science Puzzle Jul 01, 2025

Show notes

The Busy Beaver Challenge, an open online collaboration, started in 2022 to finally solve a major problem in theoretical computer science. Over time, the online community grew to include more than 20 contributors from around the world, most of them without traditional academic credentials. In July 2024, the group announced that they finally solved the puzzle, bringing a conclusion to over 40 years of effort.

On this week’s episode of The Quanta Podcast, computer science staff writer Ben Brubaker explains the tantalizing Busy Beaver puzzle, which he covered in depth last year, in "With Fifth Busy Beaver, Researchers Approach Computation’s Limits."
