Brief explainer for our new paper on arXiv! Here Ravi Kopparapu, Gongjie Li, Adiv Paradise, and I examined the effects of chaotic substellar point positions on the climate and habitability of planets orbiting TRAPPIST-1. arxiv.org/abs/2302.11561

Hear a black hole!

The misconception that there is no sound in space originates because most space is a ~vacuum, providing no way for sound waves to travel. A galaxy cluster has so much gas that we've picked up actual sound. Here it's amplified, and mixed with other data, to hear a black hole!

NASA Data Sonification: Black Hole Remix

In this sonification of Perseus, the sound waves astronomers previously identified were extracted and made audible for the first time. The sound waves were extracted outward from the center.

Time to learn some machine learning on large learning rate!

What cool effects can large learning rates create in machine learning and optimization? Theoretical perspectives are actually fun. To make them more accessible, we wrote a blog: itsdynamical.github.io/artic… Comments and questions will be appreciated!

Fun facts about large learning rates: how large is large, and what tricks they can do?
