Don’t take my explanation for an endorsement, I’ve no love for DST either

It’s about daylight savings, it provided more daylight to hunt in the evening, presumably because the day’s other activities ended earlier.

I don’t think his personal accomplishments really matter in the face of his support for the far right, crushing hatred of trans people, calling people pedophiles and the absurd amount of misinformation and bigotry that he promotes on xitter.

If SpaceX needs an absolute piece of shit like him in order to succeed, then there shouldn’t be a SpaceX.

Ah my favourite AJJ quote: “Hope is for presidents and dreams are for people who are sleeping”

Just pirate, it’s better than paying these companies to rip off artists. Support your favourite artists directly, streams are basically worthless compared to other forms of income like merch.

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.

I assume this is the “small government” party doing this?

(I’m not an American)

Yes. Almost no one smokes in Australia because of them
