“It’s hard to overestimate the influence of Fourier analysis in math,” said mathematician Leslie Greengard. “It touches almost every field of math and physics and chemistry and everything else.”
What Is the Fourier Transform? | Quanta Magazine
Amid the chaos of revolutionary France, one man’s mathematical obsession gave way to a calculation that now underpins much of mathematics and physics. The calculation, called the Fourier transform,…

Astronomers found strong evidence that a gassy Jupiter-size world is orbiting one of three stars in the stellar system closest to our own. The possible planet was discovered through observations from NASA’s powerful James Webb Space Telescope.

Did our Universe really arise from nothing?
#AskEthan
Our Universe arose from a state of inflating, exponentially expanding, empty space.
But is it really fair to say that this means our Universe came from "nothing?"

Ask Ethan: Did our Universe really arise from nothing?
The Big Bang was hot, dense, uniform, and filled with matter and energy. Before that? There was nothing. Here's how that's possible.
