thank you for your assistance... i later on figured out that it must be true since when i impose the condition that the determinant of the matrix is 1, then i end up getting SU2 group, to specify which i need three parameters... so, without the constraint of the determinant being 1, i must need...

Homework Statement how many real variables would be required to construct a most general 2by2 unitary matrix? Homework Equations a unitary matrix U is one for which the U(U hermitian) = identity matrix or (U hermitian)U = identity matrix The Attempt at a Solution first i wrote...

hi! i think you are making it a bit too complicated... to begin with, gravity doesn't play much of a role out here... it is obviously there, but it doesn't help the cart to move, provided the road is perfectly horizontal... so don't take into account forces which are simply going to clutter...

there's no need to draw so many lines as you have done in the first few diagrams... the last ones (concave, convex mirrors, i guess) are better... just remember that whatever you have, you can always draw a line through the center of curvature, which stays in its course even after reflection...

this is a very common question which comes in different forms... since it is against the forum rules, i wouldn't give you a direct answer... but think seriously about who is exerting a force and where it is being felt... and then go ahead to draw individual free body diagrams for the donkey and...

why don't you go for zemansky?? it's a bit boring with too many details but the theory is quite detailed... if you want a more preciese discussion, go for fermi...

there's hardly anything more to it... these are called low price editions... for example, mc graw hill becomes tata mc graw hill... there are loads of books of wiley, pearson education, mc graw hill, elsevier... one gets griffiths, goldstein, arfken, reif, berkeley course, zemansky, gasiorowicz...

ah, i solved it myself... i just followed the way one arrives at the gaussian distribution from the binomial distribution and the answer is W=(2^N)exp[-(2(m^2)(H^2)N)]... though this answer is not given in the book, there are problems based on this answer in chapter 3, the answers of which have...

you could try out a.j.dekker, solid state physics... simple but good and more organised than kittel...

you can go for "resnick and eisberg" for numericals and stuff... but unfortunately it is rather a book "with" modern physics, as you apprehend... another book purely on modern physics is beiser, which is very basic and real good...

go for gasiorowicz or better still griffiths... i believe there are two aspects to learning quantum mechanics... you "do" quantum, as in you do numericals and know how to deal with problems and situations... and you "understand" quantum, which is basically understanding the philosophy of quantum...

i'm not sure which country you come from, but if you're in some south-east asian country, you get these books unbelievably cheap... costs you about 3-4 american dollars... actually, there is a tie-up between the actual publishing company and some local publishing companies, and these are...

[SOLVED] reif, problem 2.4 1. Statement of the Problem Consider an isolated system consisting of a large number N of very weakly interacting localized particles of spin 1/2. Each particle has a magnetic moment 'm' which can point either parallel or antiparallel to an applied field H. The...
