In Chinese, when we want to express the idea of "change A which is erroneous to B which is correct", we usually say "correct A to B"; very concise, right? But is it the proper way to express that meaning? If so, please cite a web page containing that expression; if not, present the correct way please and cite a web page too.

Water waves are dispersive ( longer wavelengths travel faster ) but sound waves in air are not, otherwise we would listen first the high frequencies and the low frequencies after. What decides if a wave will be dispersive or not? This question has been asked again. I am looking for an answer or a comment that explains the physical reasons behind the mathematics.

Sometimes we read books rather quickly and don't give them much (or any) thought, so the action 'reading' does not necessarily imply that we have given enough thoughts to any book we read. Is there a word that describes reading a book with great care; usually but necessarily slowly over a long period of time.

Usually a two-body nuclear problem is exactly solvable through quantum mechanics e.g. the deuteron nucleus having two particles a neutron and proton. As one goes over to three particle systems, say a triton or a neutron described as composed of three quarks, the equations get coupled. Is there a simple way out to get to calculate the ground state of three particle systems?

I am not understanding why gradient will show the direction in which the function value rises most quickly. It is just the vector of partial derivatives of the function. And why its magnitude will determine how fast the temperature rises in that direction.

Online resources describe a function as a correlation between domain and range values, while a sequence is just a bunch of numbers correlated with the term. Isn't this the same thing if you consider the term to be the domain and the sequence value at that term to be the range? What's the difference between a sequence and function?

Of course, these are not designed for scheduling multithreaded programs.

Two diagonal matrices each other's entries rearranged (same eigenvalues and multiplicities), are they similar? This seems like such a simple question, but I can't quite see a connection. I want to say that the two diagonal matrices can commute with each other, and this gives us the algebraic edge to show their similarity, but I'm generally bad with abstract algebra proofs.

If a group is finitely generated, then it is a quotient of the free group on the set of generators. Further if a subgroup of a group has some finite presentation, does it mean that it is normal, intuitively a presentation corresponds to idenitifying certain element (or words), so it might be in some sense a quotient, and therefore normal. Is this right?

Math support is essential.

Similar to the Newton Raphson algorithm that has a (global) convergence property when we minimize a (strictly) convex function over Euclidean space (based on the second order Taylor serise expansion with a geometric or any other property), can we say that it also has a convergence property by replacing Euclidean space with a convex cone?

In describing electron states in hydrogen, we have a very "simple" picture, at least in intro-quantum. But this only has one electron! As we permit more electrons, we also have things like the exclusion principle, which comes from the spin-statistics theorem, but that relies on the electrons having some kind of coupled wave functions, right? Why do electrons always come in pairs?
