What Are Sheaves? | Quanta Magazine
In 1940, the French mathematician and artillery officer Jean Leray was taken prisoner by the Germans.

For the nearly five years of his imprisonment, Leray… Continue reading What Are Sheaves? | Quanta Magazine
Signs of Ancient Alien Life May Lurk within This Newfound Martian Rock
In a dry river valley on Mars, NASA’s Perseverance rover may at last have found its reason for being: evidence of ancient alien life—and with it, a lifeline for the space agency’s grand but troubled plan to bring Red Planet materials to Earth. This potentially cosmos-quaking evidence may look like merely a humble rock, but… Continue reading Signs of Ancient Alien Life May Lurk within This Newfound Martian Rock
Monumental Proof Settles Geometric Langlands Conjecture
In classical signal processing, sound waves get built up out of sine waves whose frequencies correspond to the pitches contained in the sound. It’s not enough to know which pitches the sound contains — you must also know how loud each pitch is. That information allows you to write your sound as a combination of… Continue reading Monumental Proof Settles Geometric Langlands Conjecture

How Arguments that Embryos Are People Pose a Threat to IVF
On February 16 the Alabama Supreme Court brought fertility care in that state to a screeching halt—and started a national conversation—by declaring that frozen embryos were people in the eyes of the law. In support of its decision, the court cited a 19th-century Alabama statute, the state’s constitution and, in a memorable concurrence from Chief… Continue reading How Arguments that Embryos Are People Pose a Threat to IVF
