Is twitter a place where people have pet peeves about how textbooks discuss vector calculus?

Tomorrow on #FridayNightPhysics we'll talk about what the #EHT image would look like at high res. In principle, the whole universe is in that ring! (Not a joke.) I'll explain this, with cats and ants, and answer your questions. Hope to see you there! youtu.be/8M9LrbNNeOQ
Tonight at 8pm pacific time! Important update: there will be cat sounds 🐈⬛. Also, we'll talk about @duetosymmetry's famous photon orbit website.

If you've ever puzzled over the twins, you might enjoy this 2-minute version of how relativists tend to think about it. (Sorry it's so short, but there isn't much to say!) youtu.be/oOMMaFkaEw4
Thanks to everybody who came out to my impromptu livestream and asked such great questions! It was so much fun that I've decided to do it again. I've got some topic ideas, but I bet you have better ones. What would you like to hear about? #FridayNightPhysics
My first ever tweet. I will be going LIVE tonight to discuss the EHT results (8pm pacific). I'll try to convey both the excitement and the nuance. Bring all your questions to this interactive live stream!
