I am so happy that Walrus from Space is getting some media attention. It's the only citizen scientist project I've ever participated in as a classifier, and it gave me a real sense that I could help at a time of David Attemborough-induced walrus trauma on my part...

As quirky as the project title is, this is actually a super neat program! Walrus depend on beaches for their haul-outs, which allow them to rest and to breed. As sea ice retreats, they can only haul-out on land. Walrus from Space uses crowdsourced power to identify new haul-out locations!

Marvelous new image of interstellar Comet 3I/ATLAS, taken by photographer Satoru Murata before dawn this morning.
On the right you can also see galaxy NGC 4691. There should be a lot more pictures coming in soon. 🧪🔭

I've been walking the Hadrian's Wall Path this week and a few days ago I passed by the stump of the Sycamore Gap Tree. There are saplings sprouting up from the roots all around it in a race to become the next big tree.

A moment I still remember from undergad classes: in a discussion section for first quarter QM, another student complained that she was tired of the harmonic oscillator. The TA said, "I have some bad news," and then turned and wrote on the board:
Everything is a harmonic oscillator

Free, unsolicited advice for physics students: many things will go more smoothly for you if you can derive and explain the simple harmonic oscillator in your sleep
