I am reading "Cracking the GRE Math Subject Test - Princeton Review, 3rd Ed." and and confused by the section on the chain rule for partial derivatives. The method in the book is as follows: 1) Draw a diagram to show how the variables depend on each other, with an arrow meaning "depends on"...

What symmetry gives probability conservation? Or, what symmetry does probability conservation give? I have been trying (unsuccessfully) to find an answer to this question. I think the question makes sense. That is, I can't see how the situation is different from, for example, that of spatial...

Interesting reading. I too had been wandering recently about retention of details from courses past - in particular how it seemed like I had forgotten too much! As an example I was looking over some analysis recently (I took analysis most recently in the Spring of this year) and had to show...
