@ChrisWhite My teacher admits that Myers-Briggs is too simplistic. We learn about the Minnesota test, which has ~500 questions and is constantly tweaked, but it costs money so we can't feasibly take it.
@0celo7 $L_+^\uparrow$ is some restricted Lorentz group? But, anyway, you obtain the algebra homomorphism as the derivative of the group homomorphism. In general, the adjoint group action $BAB^\dagger$ is $ba+ab^\dagger$ (for $a,b$ generators of $A,B$) infinitesimally, it has to do with some version of the BCH formula, I think.
@0celo7 Complexifying the algebra often makes things easier without significantly changing the rep theory, by the way.
@0celo7 For such covering maps, it should be an isomorphism, yes. But that doesn't change that the algebra homomorphism is the derivative (or, more precise, "induced map on tangent spaces") of the group homomorphism in general, regardless of whether one of them is an isomorphism or not.
@ChrisWhite I asked a question last year about a long chain of arguments. At least one or two papers have come out this year (which I have not edited into the question). One of the authors of one of the papers answered the question.
I also have read parts of this debate which has been going on for years.
And then there are the more "direct" fights such as this and this
I'm working on a program that has to do with adding sound waves on top of sound waves. Currently what I'm doing is simply an average of the two waves. So if I have wave A, and I want to write wave B 'on top' of it, every sample in the new A is equal to the average of two matching samples in the o...
I'm leaning towards off-topic because, while it is kind of physicsy with adding waves, it's definitely in the realm of audio engineering and there's probably scores of people on another SE that deal with exactly this problem
Where can I learn about the functionality of motors and generators, so I can answer questions such as these? I need a good textbook that starts from the basics (eg faradays) then moves up with lots of questions.
Can I also know if this is hard to pick up?
@ChrisWhite in physics, we can simply play the two sounds simultaneously. That will add them together and won't decrease the volume of any individual sound. This question has to be taken in context of combining sounds in a software program, otherwise it is so trivial that it doesn't make sense
The question asks where to find resources to solve the question. Seems on-topic in a sense to me, although I think anything about Newtonian mechanic will suffice, so I'd be a duplicate of the book recommendations
@StanShunpike I'm also in the "No" camp, but you win some and you lose some.
The"Yes" people effectively promised to keep them curated and maintained to maximize their value and minimize the basic incompatibility with the SE system. As far as I can tell they're mostly keeping up with the work.
@tpg2114 To a non-bitter and non-jaded person, they sort of appear the same
@Danu Your comment wouldn't have been rude if it were properly addressing the question. But given that it didn't, I'd say that added a "rush to judge" quality that increased rudeness above normal levels
I'd like to point on the idea of question as a knowledge resource.
It has come to my knowledge that understanding a subject, especially Physics, requires experience with as many questions as possible.
Reading many solutions of expert members of the Physics site may indeed help many students t...

I use No Comment when I add my own comment in. If I can explain why I think it's inappropriate as a posted answer to the question, then I write that comment and select no comment needed, because I provided one already
A downvote should be the solution in the case the post is not useful. As in:
It is technically correct, but isn't clear.
It is technically correct, but is only a link or is of some other value.
It is technically incorrect, but is of some value to the original question.
Deletion is r...
If a question is flat-out wrong on top of being exceedingly brief, in poor English, or whatever, by all means vote to recommend deletion.
If it looks beautiful except for being wrong, I'd stick with downvotes and comments.
> If it looks beautiful except for being wrong, I'd stick with downvotes and comments.
A bad or a wrong answer is still technically an answer. Moderators aren't here to judge the correctness of answers. That's what the voting system is for, so the right way to handle those is to downvote, edit, or leave a comment.
The "not an answer" flag is for posts that are either completely un...
Other than off topic flags, there are several different types of flags that one can cast on a question, answer, or comment. What are each of these flags for?
Question and answer flags:
not an answer
very low quality
rude or offensive
@danu there's certainly overlap between maths and physics - as @kyle noted, occasionally revolutionary developments in maths were motivated by physics, and vice versa - but the overlap between the histories maths and e.g. biology is tenuous.
