@DanielSank Neither. And I won't get married or have children while being "on the move", but I don't think I want to get married or have children in the next ten years.
Now, I know the need to create standards for asking questions. However, particularly for first time users, the ability to ask questions in a way that this forum expects can be difficult, often due to a lack of language surrounding the topic they are asking about. As a result, their question get...
I've raised a question that was put on hold, here:
Could a falling office tower cause the melting of its iron or steel support structure?
I wanted to post about a topic for discussion about why the question was put on hold. I would preface that I don't want to offend anyone, raise defences, br...
I am quite confused with the groups Diff$(M)$ and $GL(4,\mathbb{R})$ in the context of general relativity. I understand that the symmetries of GR are the transformations that leave the equations invariant under under continuous smooth coordinate transformations. That is, automorphisms $f:M \to M$...
@DanielSank: You're probably there at wrong times.
@DanielSank: There's very often really bad drama because some people can't stand each other. But also often there are rather vivid discussions. Not sure if they are about anything you're interested in, though.
@DanielSank: What math topics do you like talking about? From my experience, it's a lot less dead than this chat, to be honest.
then you should frequent the chat and soon you can ping. :P
just ask the question in the chat. a lot of people are actually around but don't talk if nothing interesting is going on (or nobody interesting is around)
for example, I'm online all day but right now I'd like to talk about some geometric topology but neither Balarka nor Mike are on so I don't really say anything.
@Danu In a sense that is strange because there was never any guarantee (or even a good odds) of finding evidence for string theory at LHC energies.
On the otherhand, a lot of students needed thesis projects so there were a lot of "well, if we assume that [parameter] has [the right range of values] then we might see [effect] at LHC energies..." going on.
The important thing here is what they call you after you turn in a dissertation based on a null result ...
Doctor.
Then they shake your hand and go back to calling you by your first name, because that's the culture in particle physics.
I don't claim these analyses weren't worth doing. The data needed looking at, but the driving reason for the LHC was a much more general search for new physics.

@0celo7 : yes I read your list of reasons. Picking one at random: curved space and curved spacetime might be used interchangeably in your conversations, but they are not the same. The distinction is crucial. All the votes in the world won't make them the same.
In particular, it's irrelevant for any answer to my question.
@JohnDuffield Suppose I replace "curved space" with "curved spacetime" and "follows a null geodesic" with "the integral curves of the wave vector are null geodesics"
@JohnDuffield What is the remaining content of the deleted post?
what is the correct way to take the exterior derivative of the product of two functions? i.e $d(fg)=?$ Here is my attempt, but I am left with a result that doesn't look too good imo... $d(fg)=d(f\wedge g)=dg\wedge f+g\wedge df $
@Danu : anna asked for opinions, I gave mine. And it looks to me as if you're touting for serial downvotes. If you've got an issue with my answer point it out and let's talk about it. If you dare.

I was asking for a clarification
My question was not Homework type
I had worked out a solution myself
