This might be late, but hopefully it will be useful to someone Alexander Maloney's lectures on QM using Sakurai He also has other excellent courses on his web page, I really liked his GR lectures, they were so superb http://www.physics.mcgill.ca/~maloney/

I revised my classical mechanics couple of years ago, and I used both books, My main source was K&K, which was superb in explaining the theory ( better than Morin's), but when it came to problems and problem solving techniques, Morin was better ( Also I like to add, the footnotes on Morin are...

Look at this post

If you're planning to study Griffths elementary particles, then Zetilli will prepare you better ( I kid you not ), though If you can afford it, getting both books is better than just one.

Sorry, I had to use Paint to Illustrate my solution, I hope that it is right

Hello, I am taking a class in RA, where we're using Bartle/Sherbert. Since I have studied few chapters from it in the summer before, I decided to take a look at a more rigorous book, like baby rudin, but since many have advised against that book, I turned to Pugh's real mathematical analysis...

After reading your replies, and looking through examples, things started to make sense, thank you very much :)

Hello, I am teaching my self real analysis from Pugh's Real Mathematical Analysis, and I came acrosse the construction of reals through Dedekind cuts, but am confused about the following: Dedekind cuts are defined as follows ( Pugh's page 11): A cut in ##Q## is a pair of subsets ##A,B ## of...

I highly recommend Shankar's QM(1) Book, it undergraduate/beginning graduate level, starts off with a chapter on the linear algebra that you need ( using Dirac's bra-ket notation), and then after a quick review of classical mechanics, proceeds to build the theory from the 'postulates' of Quantum...

Hello, thank you for your answer, I have proved the case for the union of two subspaces (I used the same idea that you suggested ) , my problem is the union of three subspaces. The post is not complete yet, as I'am learning how to post using latex,I intended to delete this thread but I...

Homework Statement Prove the the union of three subspaces is a subspace if one of the subspaces contains the others Homework Equations A subset W of a vector space V is called a subspace if : 1) ##0 \in W ##. 2) if ##U_1## and ##U_2## are in ##W##, then ##U_1 + U_2 \in W##, 3) if ##\alpha ##...

Thank you for your post, very helpful, looking forward to the next part, but I wish that there was more elaboration on why one should study real analysis, and the importance of real analysis on later courses of mathematics, also more elaboration on the struggle of self learner and how to...

Instead of buying textbooks, which are generally not very affordable, especially for high schooler, not to mention the currency difference and the shipping costs, I highly recommend you to watch online lectures from sth. like www.khanacademy.org, I think it has everything you need.

Thank you very much sir, I think my problem was with English more than it was with physics, I thought what he meant be pivot is the joining point of the arms with the peg, now I got the solution right.

Yes you're right. I first wrote a long reply, then i noticed that he said " cal based physics 1" so I assumed that he meant physics at the level of K&K.
