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

Recently, astrophysicists identified something peculiar: An enormous “naked” black hole with no galaxy in sight. On this week’s episode, host Samir Patel speaks with physics staff writer Charlie Wood about how the strange little red dot is upending our assumptions of the first billion years of cosmic history. This topic was covered in a recent story for Quanta Magazine.

Thanks to a delicate interplay between plate tectonics and life, Earth’s thermostat has kept animal life thriving on our planet for half a billion years. On this week’s episode, host Samir Patel speaks with contributing writer Peter Brannen about our planetary highs and lows, and the precarious goldilocks zone our animal-filled finds itself in now. This topic was covered in a recent story for Quanta Magazine.

Imagine a set of simple building blocks that can self-assemble into any shape you want. The possibilities for such a technology could be boundless. Inspired by nature, “complexity engineering” seeks to design such blocks, building on a classic computer simulation. On this week’s episode, host Samir Patel speaks with contributing writer George Musser about recent developments in so-called cellular automata. This topic was c...

Around 6,000 years ago, the Sahara was a lush grassland. Then, as if a switch flipped, it began to dry out, becoming the desert that we know today. Tipping points are moments in Earth’s history where gradual change suddenly becomes rapid and forms a new equilibrium.

They’re one of the most alarming threats of our planet’s near future — and one of the most uncertain.

When will a tipping point occur? Mathematicians are attempt...

“Memory” means many things to many people, and in many fields. We tend to understand memory to be a phenomenon that happens primarily in the brain, but in recent years, researchers have understood memory as a physical phenomenon that can occur in plenty of systems. On this episode, contributing writer Claire L. Evans tells host Samir Patel about how neuroscientists are probing the memory of individual cells.

In order to trust machines with important jobs, we need a high level of confidence that they share our values and goals. Recent work shows that this “alignment” can be brittle, superficial, even unstable. In one study, a few training adjustments led a popular chatbot to recommend murder. On this episode, contributing writer Stephen Ornes tells host Samir Patel about what this research reveals.

For most of us, the word “climate” immediately generates thoughts of melting ice, rising seas, wildfires and gathering storms. However, in the course of working to understand this pressing challenge, scientists have revealed so much more: A fundamental understanding of how Earth’s climate works. 

Quanta recently published a nine-story series that investigates this basic science. On this episode of The Quanta Podcast, senior...

In the field of harmonic analysis, there’s a constellation of questions about how the energy of a wave concentrates.

Earlier this year, a 17-year-old high school student named Hannah Cairo solved a 40-year-old mystery about how some of these waves behave, surprising and exciting mathematicians. Cairo has not yet obtained a high school or undergraduate degree, but she recently began a doctoral program at the University of Ma...

In science textbooks, Earth looks like a round layer cake. There's a hard line between the liquid metal core and the putty-like rock mantle. But maybe that boundary is a little fuzzier than we previously thought. Strange, continent sized blobs rest on the dividing line. These blobs are leaching material from the Earth’s core, extending arms out into the mantle, and sending core material up and out through magmatic plumes.

We’re living in the golden age of cryptography. Since the 1970s, we've had more confidence in encryption than ever before. But there's a difference between confidence and absolute certainty. And computer scientists care a lot about that difference.

The search is always on for better, more secure secrets. But is it possible for digital security to be truly, provably unbreakable? Maybe, with a little help from math and physic...
