In Wikipedia, spacetime intervals are presented explicitly under the heading "Spacetime intervals in flat space"; apparently including a presentation of spacetime intervals for (all) pairs of events in flat spacetime.
Now, certainly spacetimes may be considered such that none of their subsets c...
@0celo7 One can just define it as a solution to the EFE's. I agree that the embedded one is nicer (I also started my thesis with it). It immediately shows what the isometries are.
@0celo7 Have people vouch for you, do some extracurricular projects, etc
@Rigor Probably not that impressive for a student to do well on the first exams. But yeah, of course you should get good grades for people to believe in you.
::sigh:: Do people actually think "I don't understand this and it involves light in any way at all. Obviously it's a physics question." or does it just seem that way?
I know that our brain perceives two images from two eyes and combine them to see 3 dimensions and the 3D stuff uses this. But how this works and how can there be two images ? Thanks in advance, good night. (If I did something wrong, sorry. I'm not native speaker.)
FITS is a pretty generic format, so the trouble comes in know how a particular subfield is using it. Those question aren't very physicy either but at least they are questions that physicists actually have.
they don't want to hire people for the top positions if they don't work well with others
also there's the halo effect

@FenderLesPaul They were somewhat inflated. I'd say a better word would be de-spread. Very few people got less than a B, and about 1 person per year would manage to get an A+.

That said, the physics department had the right attitude about grad classes -- they were all pass/fail, even if you were an undergrad.

Our core applied math (complex analysis/differential equations) class was taken by a large fraction of undergrads and grads, the former for grades, the latter not. What's really sad is that it's a sophomore level class, and many of the incoming grad students had to take it because their undergrads never taught them how to do contour integrals.
@0celo7 @ChrisWhite probably knows inside and out whether or not they have pure GR theory people but I think all their research is numerical GR/astrophysics or quantum gravity stuff

@FenderLesPaul That's my understanding too. But that's my perspective as someone tangentially related to numerical GR, and as someone not in the physics department proper. There might be pencil-and-paper GR types hiding that I don't interact with.
@Danu Yeah, and he seems to leave everyone with either a very good or very bad impression. Never met him myself, but I have shaken Gell-Mann's hand once.
In the last couple of decades society has ceased to make a carefully drawn distinction between people who seek out sexual relationships with young but sexually mature people and those who seek them with pre-pubecent people.
