As far as we know, quantum mechanics is a universal theory that explains matter and light more or less perfectly. It shows us why atoms don't collapse and why electrons don't spiral into the nucleus of the atom. It explains why glass is clear, why grass is green, why the sky is blue. But no one fully understands how the math of quantum mechanics connects with the reality we live in. One could spend a lifetime getting into the weeds and still have unanswered questions.  In honor of quantum mechanics’ 100th birthday, host Samir Patel talks with Quanta physics staff writer Charlie Wood about his recent journey to the birthplace of quantum mechanics, a German island in the North Sea. On Helgoland, Charlie asked physicists many questions about many worlds over many beers. This topic was covered in a recent story for Quanta Magazine. Each week on The Quanta Podcast, Quanta Magazine editor in chief Samir Patel speaks with the people behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math.

When some people smell the molecule benzyl acetate, they identify a distinctly banana-y scent. But when others sniff the same compound, they get hints of nail polish remover. How can this be? Smell is a tricky sensory process to pin down. Our perception of scents is wide-ranging and often depends on lived experience. But researchers are building a deeper understanding of the processes underlying our noses’ elusive machinery.  In this episode, host Samir Patel and 𝘘𝘶𝘢𝘯𝘵𝘢 biology staff writer Yasemin Saplakoglu explore the invisible sense that shapes our reality, from nostalgic childhood fragrances — lavender, old books — to familiar irksome odors — skunks, garbage. This topic was covered in a recent story for 𝘘𝘶𝘢𝘯𝘵𝘢 𝘔𝘢𝘨𝘢𝘻𝘪𝘯𝘦.

By screening films in a brain scanner, neuroscientists discovered a rich library of neural scripts — from a trip through an airport to a marriage proposal — that form scaffolds for memories of our experiences.

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.” Each week on 𝘛𝘩𝘦 𝘘𝘶𝘢𝘯𝘵𝘢 𝘗𝘰𝘥𝘤𝘢𝘴𝘵, 𝘘𝘶𝘢𝘯𝘵𝘢 𝘔𝘢𝘨𝘢𝘻𝘪𝘯𝘦 editor in chief Samir Patel speaks with the people behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math.

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.

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. Each week on The Quanta Podcast, Quanta Magazine editor in chief Samir Patel speaks with the minds behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math.

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.

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."
