Hi Mongoose,
Although this isn't the book, after looking through the TOC it looks VERY interesting and probably has what I'm looking for in at least one of the examples and maybe even more information about other scenarios. Thanks so much.

Hi,
I was reading a general mathematics/ number theory (at least college level) book (NOT a textbook) at Barnes & Noble about a year ago. I can't remember the title but maybe someone on here does...
In this book there was an example of a cat in pursuit of a mouse problem using complex...
Ohhh. I think I know what happened. I hit the submit button instead of the preview button. I hit the stop button on my browser, but apparently is must have been too late. Sorry about that.
The QED Lagrangian is given by \mathcal{L}_{\hbox{QED}} = \bar{\psi}(i\partial - m)\psi
- \frac{1}{4}(F_{\mu\nu})^2 - e\bar{\psi}\gamma^\mu\psi A_\mu
What is the purpose of the middle term. I know that it represents the energy of the E and B fields. However is that due to the external...
Thanks for that explanation. If I was being unreasonable, it is only because I don't need to be told that I should pick up a book or take a course in something that I have already taken. This was mainly for the people who wanted to see (including myself) how these eigenstates and eigenvalues...
First of all it is not of your concern to tell me what I should and should not know. That's a big problem within the real world of physics which you have not reached yet. Everyone, or maybe just the hot shots, wants to prove that they know so much and that the next person doesn't know anything...
Balkan, why are you assuming that I haven't taken QM! Very bad. I have had more courses in advanced QM and QFT, String theory than you probably even knew existed and honestly if I wanted to know I'd just figure it out for myself. Would you like for me to explain to why or why not this is...
Hey, I'm not sixteen and I would really like the know the answer to that. There are others viewing this thread you know. Please share because I never knew that was possible.

I just finished reading in a book entitled How is Quantum Field Theory Possible? by Sunny Y. Auyang that the fields are local fields whose Lagrangians depend only on the properties in the infinitesimal neighborhood of the point x. If this is the case, then I might have an easier time...
The theory of quantum fields is very strange, indeed, I must admit. Usually in books they introduce a quantum field from the standpoint of a vibrating string in one dimension. Along the string are discrete points or masses that when one of which are disturbed a disturbance is created along the...
