Given some of Intel’s crap lately, meeting the bare minimum could be considered a big thing for them

Oh god the case for a photon is super hard to talk about in any meaningful way, photons “see” every point in their journey as happening at the same instant of time and at the same place, null geodesics are nuts.

But yeah, the underlying mathematics that causes this can (kinda) just be pinned on the normalisation of the four velocity, which I think is what you’re describing.

Only a few really dry textbooks I’m afraid, it’s a subject that’s extremely difficult to explain in lay terms as the mathematics is so complicated.

That said if you’re feeling masochistic, Schultz’s first course in GR is the most approachable that I know.

It’s just meant as a physical analogue to demonstrate some features (namely how the shape of the sheet/gravity affects things that travel on/through it) in a way that people can understand easily.

Variational principle goes brrrrr

Oh yes let’s talk about my favourite subject ever!

The coolest thing I know of comes from wondering why bent spacetime makes you move at all. The answer is that you always move through time and the bending of spacetime actually turns a bit of time into space and vice versa.

This leads to my favourite saying about black holes, once you enter them you can no more escape falling to the singularity than you can escape tomorrow.

Holy shit this is some of the absolute worst data visualisation I’ve ever seen, thankyou for this

I’m sorry what? Plex has ads???

Very fucking glad I just ignored it and went with jellyfin…

I can highly recommend symfonium as a front end for a jellyfin music library on android, it’s super clean and has tons of nice features.

Yep, I’m using one right now. Upvotes for everyone!
