Is AI Reasoning Right for the Wrong Reasons?
Reasoning comes in many technically defined forms, but the basic procedure is easily recognizable: arriving at a sound conclusion by linking...
Why Am I Left-Handed?
Why are only 10% of people left-handed? Geneticists, developmental biologists, neuroscientists, and evolutionary biologists have all sought...
Is Life Just Different?
There’s no scientific consensus about what makes living things so different from inorganic material. Some scientists cite replication or met...
How Many Shuffles Do You Really Need to Randomize Your Deck?
In 1992, mathematicians Dave Bayer and Persi Diaconis proved that seven riffle shuffles are enough to shuffle a deck of cards — but only if...
How Many Elementary Particles Are There, Really?
How many pieces are there in the Standard Model of particle physics? 17, 30, 37, 61, 118? Or is the true answer much larger — and not even a...
The 'Truth Machine' That Is Changing Math
The groundbreaking proof assistant Lean acts as a sort of automatic quality control. It’s gaining ground in the math world — in part because...
Ecotypes Make the Idea of a Species Even Fuzzier
How do you define a species? The question has been controversial since the days of Darwin. On this episode of The Quanta Podcast, host Samir...
What Actually Causes Lightning?
Thunderstorms have captivated humanity for millennia, and yet their inner workings remain deeply mysterious. On this episode of The Quanta P...
What Can We Gain by Losing Infinity?
Most mathematicians take the notion of infinity for granted — it’s deeply rooted in math’s most fundamental assumptions. But a small group o...
Audio Edition: The Cells That Breathe Two Ways
In a hot spring at Yellowstone National Park, a microbe does something that life shouldn’t be able to do: It breathes oxygen and sulfur at t...
Quantum Mechanics Might Be a Secret Key to Secure Communication
Together, Charles Bennett and Gilles Brassard figured out how to use the laws of quantum physics to keep secret messages safe from eavesdrop...
Is String Theory Still Our Best Hope?
Is string theory the one true “theory of everything?” Some physicists swear it’s a fundamental ingredient of nature. Others wish it would ju...
Audio Edition: New Physics-Inspired Proof Probes the Borders of Disorder
For decades, mathematicians have struggled to understand matrices that reflect both order and randomness, like those that model semiconducto...
One of Nature's Most Complex Molecular Machines
At the center of little holes in cell nuclei is a mystery. Here, clumps of proteins wiggle disordered tails around like seaweed. They drive...
The Fundamental Tension at the Heart of Math
We tend to think of math as all about logic and rigor. But what “rigor” actually means has been shaken up quite a few times over the past fe...
Audio Edition: AI Comes Up With Bizarre Physics Experiments. But They Work.
Artificial intelligence software is designing novel experimental protocols that improve upon the work of human physicists, although the huma...
Why Do Humanoid Robots Still Struggle With the Small Stuff?
Humanoid robots can run, crawl, and sort objects in flashy demos. So why can’t they reliably climb stairs or open doors? On this episode of...
Uniting a Century of Digital and Analog Astronomy
To better understand our cosmos, some astronomers and astrophysicists go old school. Preserved beautifully on a hundred years of glass plate...
Audio Edition: Researchers Uncover Hidden Ingredients Behind AI Creativity
Image generators are designed to mimic their training data, so where does their apparent creativity come from? A recent study suggests that...
