In 1874, Georg Cantor published one of the most important papers in math’s 4,000-year history. Some ideas in it were stolen. On this episode of The Quanta Podcast, the first of a two-parter, host Samir Patel speaks with math editor Jordana Cepelewicz about the hard-fought journey to embed the concept of infinity into math’s foundations. The real story is a lot more complicated than the one remembe...

Parallel universes, mysterious collapses, divided worlds. These are among the interpretations of quantum theory’s relationship with reality. It’s no wonder that everyone still has questions. But a century after quantum theory emerged, some of its old mysteries may be finally dissolving. On this episode of The Quanta Podcast, host Samir Patel and contributing writer Philip Ball check in on the age-...

By mathematically proving how individual molecules create the complex motion of fluids, three mathematicians have illuminated why time can’t flow in reverse. The story Epic Effort to Ground Physics in Math Opens Up the Secrets of Time first appeared on Quanta Magazine.

What guides a bat’s internal compass? It’s not the stars in the sky, or the Earth’s magnetic field. On this episode of The Quanta Podcast, host Samir Patel speaks with staff writer Yasemin Saplakoglu about how new research into animals’ sense of direction could help explain the feeling of getting “turned around,” or even why some of us are so bad at finding our way. This topic was covered in a rec...

In reality, water doesn’t glitch out. It can’t instantly change direction or spurt randomly into the sky. But on a purely mathematical level, such things are possible. On this episode of The Quanta Podcast, host Samir Patel speaks with staff writer Charlie Wood about the equations that describe our rivers, whirlpools, and breezes — and the “unstable blowups” that mathematicians are probing them fo...

Every elementary particle falls into one of two categories. Collectivist bosons account for the forces that move us while individualist fermions keep our atoms from collapsing. The story Matter vs. Force: Why There Are Exactly Two Types of Particles first appeared on Quanta Magazine.

In the allegory of Plato’s cave, prisoners see the world only through shadows. Extending this metaphor to AI, AI models are the prisoners and the shadows are streams of data. Are all models converging on a singular representation of reality? On this week’s episode of The Quanta Podcast, host Samir Patel speaks with staff writer Ben Brubaker about how, despite being trained on entirely different da...

Particle physics hasn't yet found the new physics needed to resolve its deepest mysteries. It’s hard to know what to think about or look for. But the most devoted particle physicists are thinking and looking all the same. On this episode, host Samir Patel and columnist Natalie Wolchover discuss the first of our new series of curiosity-driven essays, Qualia, where Natalie asks particle physicists w...

Reversible programs run backward as easily as they run forward, saving energy in theory. After decades of research, they may soon power AI. The story How Can AI Researchers Save Energy? By Going Backward first appeared on Quanta Magazine.

We already know that what we eat, drink, and inhale can affect which parts of our DNA are expressed, and which aren’t. But recent research poses a shocking idea: A dad’s habits may be encoded in molecules and transmitted to his future kids. On this episode, host Samir Patel and biology editor Hannah Waters dig into the new epigenetic mouse studies exploring whether sperm cells carry more than just...

Imagine you’re holding two equal-size dice. Is it possible to bore a tunnel through one die that’s big enough for the other to slide through? It is — but what about other shapes? In a paper posted online in August, two researchers describe a shape with 90 vertices and 152 faces that they’ve named the Noperthedron, the first convex polyhedron that definitely cannot pass through itself.  In this epi...

Studies of neural metabolism reveal our brain’s effort to keep us alive and the evolutionary constraints that sculpted our most complex organ. The story How Much Energy Does It Take To Think? first appeared on Quanta Magazine .

Ask ChatGPT how to build a bomb, and it will flatly respond that it “can’t help with that.” But users have long played a cat-and-mouse game to try to trick language models into providing forbidden information. Just as quickly as these “jailbreaks” appear, AI companies patch them by simply filtering out forbidden prompts before they ever reach the model itself. Recently, cryptographers have shown h...

(This episode was first published in June 2025.) Changes in the number, shape, efficiency and interconnectedness of organelles in the cells of flight muscles provide extra energy for birds’ continent-spanning feats. This is the fifth episode of The Quanta Podcast. In each episode, Quanta Magazine editor in chief Samir Patel speaks with the minds behind the award-winning publication to navigate thr...

(This episode was first published in July 2025.)  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 gr...

By extending the scope of the key insight behind Fermat’s Last Theorem, four mathematicians have made great strides toward building a “grand unified theory” of math. The story The Core of Fermat’s Last Theorem Just Got Superpowered first appeared on Quanta Magazine.

We all know that hot coffee cools down. But quantum mechanics can enable heat to flow the “wrong” way, making hot objects hotter and cold objects colder. Now physicists think this might have an ingenious use. On this week’s episode, host Samir Patel speaks with writer Philip Ball about how a new "quantum demon” may allow information to be processed in ways that classical physics does not permit. T...

In math and science, knots do far more than keep shoes on feet. For more than a century, mathematicians have studied the properties of different knots and been rewarded by a wide range of useful applications across science. Classifying how some knots are different from others is an important part of this work.  Earlier this year, two mathematicians found that a theory for how to differentiate betw...

When pigeons outnumber pigeonholes, some birds must double up. This obvious statement — and its inverse — have deep connections to many areas of math and computer science. The story How a Problem About Pigeons Powers Complexity Theory first appeared on Quanta Magazine.

Every summer since 1983, scientists at Crater Lake National Park have gathered data about the lake’s famous clarity. This past summer, Quanta contributing writer Rachel Nuwer journeyed with them as they conducted their annual tests. On this week’s episode, Nuwer and host Samir Patel discuss what gives the lake its vivid blue color, and what its data can tell us about the way water moves through a...

How do sellers decide how to price their goods? Competition should keep prices down, while collusion can rig higher prices (and break the law). On this week’s episode, host Samir Patel speaks with staff writer Ben Brubaker about how computer scientists are using game theory to see how algorithms might result in high prices without shady backroom deals. This topic was covered in a recent story for...

At first glance, studying the math of waves seems like it should be smooth sailing. But the equations that describe even the gentlest rolling waves are a mathematical nightmare to solve. On this week’s episode, host Samir Patel speaks with math staff writer Joseph Howlett why waves are so elusive, even in a simplified world of equations. This topic was covered in a recent story for Quanta Magazine...

Salvador Dalí, Thomas Edison and Edgar Allan Poe all took inspiration from the state between sleep and waking life. On this week’s episode, host Samir Patel speaks with biology staff writer Yasemin Saplakoglu about how brain systems dictate the strange transitions into and out of sleep.
