    Algebra Math texts that make you fall in love all over again

    Try "Mathematical methods of classical mechanics," "Ordinary differential equations" and "Partial differential equations" by V.I. Arnold. "Analysis by its history" by Hairer and Wanner is very nice too. Enjoy :-)

    High School What does the derivative of a function at a point describe?

    But endeed, the full power of classical analysis and limit theory is not needed to understand differentiation. It can be done on a more elementary level. Unfortunately not too many people are aware of it.

    High School What does the derivative of a function at a point describe?

    Sorry, this definition does not work, consider the derivative of ## x^3 ## at ## x=0 ## or ## x^2sin(x^{-2}) ## (taken to be 0 at 0) at ## x=0 ##.

    Graduate What math do I need to know to understand General Relativity

    As the general math background for physics, V.I. Arnold's Mathematical Methods of Classical Mechanics is the best.

    Graduate What math do I need to know to understand General Relativity

    And there is a great book "Gravitation" by Mister, Thorne and Wheeler that explains all the math along with GR, fun to read, try it.

    Graduate What math do I need to know to understand General Relativity

    Pick up the book "The Principle of Relativity" and try to read the Einstein's paper on GR. You will see the math you need. Good luck.

    Does G(x) = x^2 - e^{1/(1+x)} Assume a Value of 0 for 0 < x < 2?

    Can you see whether G'(x) is positive or negative for positive x?

    Continuously Differentiable Piecewise Function?

    Looks like your teacher is wrong, the function is continuously differentiable.

    Graduate Why Pauli's Exclusion Principle?

    http://www.arxiv.org/abs/hep-th/0008072 http://www.arxiv.org/abs/quant-ph/0208151 Type in spin statistics into the title window for a lot more, search both physics and math, enjoy.

    Graduate Why Pauli's Exclusion Principle?

    There are some other nice articles on the subject in arxiv.org. I especially liked the ones by Robert Oeckl and by Bernd Kuckert. It looks like a lot of confusion is created by forgetting that the individual particles don't exist, the n-particle states live on the n-configuration space...
