Beyond Euclid #213

Welcome to Beyond Euclid #213, the newsletter for the best mathematics and science stuff of the week. I am Ali, and I curate cool math and science stuff every week to help you have a better week.

Hello from Beyond Euclid 213. This issue starts with category theory and ends with the internet being its usual chaotic self. In between there’s rocket photography, squeaky sneaker physics, miniature furniture, and Anthropic telling the Pentagon “no.” As always, the thing I find most interesting is how ideas that seem totally unrelated end up asking the same question in different languages. That happens a few times this issue. Let’s get into it.

But first, a quick note. Finding the signal in the noise — tracking down the right sources, cutting the junk, writing all of it up — takes a lot of time each week. If you find this worth your while and want to help keep it going, you can become a paid subscriber on Substack. Patreon is also an option. Sharing it with someone who’d enjoy it works just as well. Either way, glad you’re here.
