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.

Constance? Never heard of her

Having never done it as part of one such group, I don't know exactly what goes on, but essentially there's a large body of literature on leftist political concepts, covering the ideas of why anarchy rather than archy, how to practice it, how to organise etc. I'm definitely the wrong person to explain it, generally socialists (at least here) are the ones doing all the reading, I'm a lot more interested in praxis tbh.

Some classic anarchist writers include Kropotkin, Bakunin and Proudhon, but the communist and socialist literature often applies too.

The anarchist library has lots to browse and the anarchist faq is a great starting place despite its huge volume of content, I highly recommend casually browsing it.

As a theoretical physicist, units are for chumps

We do! In my area there are quite a few of us and we operate a number of collectives providing things like:

• Free meals
• Free groceries
• Bike repair workshops
• Theory reading groups
• Clothing
• Social activities

Of course there's also a lot of direct action going on for various causes.

Are you using web or an app? If it's an app then I guess it just depends what you're using?

Yeah my current bike is literally just an abandoned bike that I repaired, so I doubt anyone's gonna want to steal it. If I get another E-Bike I'll be a lot more particular about where and when I leave it, and use multiple locks

I bought an E-Bike, the impulsive bit was not getting a normal bike.

I kinda just figured it would be fun, and probably useful for some longer trips through the city. It ended up being one of the most empowering things I've ever owned, I have a pretty nasty health condition with lots of really bad fatigue and I live in a hilly area. I was able to look after myself to a whole new level, it was in almost every way a mobility aid for me, it made it possible for me to get supplies and meds on bad days it was a game changer.

Anyway it got stolen a couple of weeks ago so that's cool

What a horrible waste of oxygen

Come on, you can't just leave those dummy indices dangling, at least sum over them with a kronecker delta or the minkowski metric if this is some approximation of curved space.

(2) Appears to have a typo, but it could just be that the sqrt symbol won't extend further, which isn't good either lol
