How Does Math Keep Secrets?

Can you keep a secret? Modern techniques for maintaining the confidentiality of information are based on mathematical problems that are inherently too difficult for anyone to solve without the right hints. Yet what does that mean when quantum computers capable of solving many problems astronomically faster are on the horizon? In this episode, host Janna… Continue reading How Does Math Keep Secrets?

What Happens in a Mind That Can’t ‘See’ Mental Images

Two years ago, Sarah Shomstein realized she didn’t have a mind’s eye. The vision scientist was sitting in a seminar room, listening to a scientific talk, when the presenter asked the audience to imagine an apple. Shomstein closed her eyes and did so. Then, the presenter asked the crowd to open their eyes and rate… Continue reading What Happens in a Mind That Can’t ‘See’ Mental Images

Catching Fish with Ancient Archaeology and Ocean Tides

[CLIP: Theme music] Rachel Feltman: What do you think of when you hear the word “archaeology”? Maybe your mind goes straight to Indiana Jones. Or perhaps you picture real-world academics in the field—ones who handle their dusty desert dig sites and crumbling artifacts with far more care. But studying how ancient humans lived and died… Continue reading Catching Fish with Ancient Archaeology and Ocean Tides

Grad Students Find Inevitable Patterns in Big Sets of Numbers

Forty years later, in 1975, a mathematician named Endre Szemerédi proved the conjecture. His work spawned multiple lines of research that mathematicians are still exploring today. “Many of the ideas from his proof grew into worlds of their own,” said Yufei Zhao, Sah and Sawhney’s doctoral adviser at MIT. Mathematicians have built on Szemerédi’s result… Continue reading Grad Students Find Inevitable Patterns in Big Sets of Numbers

Physicists Pinpoint the Quantum Origin of the Greenhouse Effect

In 1896, the Swedish physicist Svante Arrhenius realized that carbon dioxide (CO2) traps heat in Earth’s atmosphere — the phenomenon now called the greenhouse effect. Since then, increasingly sophisticated modern climate models have verified Arrhenius’ central conclusion: that every time the CO2 concentration in the atmosphere doubles, Earth’s temperature will rise between 2 and 5… Continue reading Physicists Pinpoint the Quantum Origin of the Greenhouse Effect

Taylor Swift and Bach Can Thank Ancient Temples for Modern Music

Where did Western music come from? Most historical accounts credit composers with the first formations of simple tunes, which eventually led to “early music” and later classical music and the many popular forms that have since sprung up. But acoustic ecologists and musicologists have been talking lately about a different foundation: the earliest temples and… Continue reading Taylor Swift and Bach Can Thank Ancient Temples for Modern Music

How to See Stars, Satellites, and More in the Daytime Sky

How to See Stars, Satellites, and More in the Daytime Sky It’s possible to see celestial objects during the day, but it’s not always easy By Phil Plait It seems pretty obvious that you can’t see any stars in the daytime. If you were to say that to me, however, I would gently take you… Continue reading How to See Stars, Satellites, and More in the Daytime Sky
