Thank you for breaking it down into parts: a') Because we can't see/perceive "further/higher". b',c') Taking (a'), how can I make sure it will not affect (b,c)?

What bcrowell is referring to is the addition of angular momenta. A look at 1x1 table of this document might shed some light (taking the context for granted): http://cms.iafe.uba.ar/carmen/clebrpp.pdf The idea also applies to the spin of electron-positron pair.

How do we know that the (effective) dimensionality of "space" is three in a typical physical theory?

I think the problem wants you to assume the Airplanes have that speed relative to the air that is itself moving; if so, you need to subtract the projection of the wind velocity along the flight direction and that is going to give you the actual speed for each specific flight (that makes a...

Fourth line, second term, I think the plus should be turned to minus..

I found this thread looking for a pop science explanation of the matter. Well it's two years now, but I am going to share my point for what it is worth: Ulysees had a point and his/her argument is valid as long as you're off the continuum limit. Consider a 1-d conductor, circle in shape, with 4...

The definition as I heard from the instructor is as follows: A decay is isotropic if it is so in the Center of Mass frame; in the sense that the decay products come out in all angles with the same probability (but of course with fixed relative angles between them imposed by momentum conservation).

I am looking for some worked examples of calculating moment maps. I have to calculate some moment maps but have no idea how to step further from the solid definitions I have seen. I would appreciate any help in this regard.

I think it should mean of the following: 1- the magnitude of spatial momenta is almost the same for all decay products, 2- the magnitude of temporal momenta (energy) is almost the same for all decay products. But I can't figure out which description is actually meant just from the look of...

I knew that sense of the term, but that meaning doesn't really help solving the this problem.

I am trying to solve a problem from Jackson's and it says that the decay in particle's rest frame is more or less isotropic. I was wondering if somebody could help me figure the meaning of an 'isotropic decay' here. Thank you in advance.
