    Best Books for Learning C++

    Here's a list: http://stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list Is this your first programming language? Then please do not start with C++. Start with something like Python or Ruby -- it is far more accessible. You can move on to C++ at a later stage.

    Quantum Quantum Field Theory in a Nutshell by Zee

    Great read and a good book. Lots of topics and a refreshing look on QFT. Highly recommend it. One caveat: you cannot learn QFT from this book. It simply does not dive into any details of the calculations. It's great as a supplement, but keep in mind that no course on QFT will ever use this...

    Quantum An Introduction to Quantum Field Theory by Michael E. Peskin

    This massive book on QFT is a standard text nowadays and used at many universities. The book is extensive and very detailed. If you manage to follow the text and keep up with all the nitty-gritty details, then you are well underway into mastering QFT -- but this is quite a challenge. The book is...

    Quantum Quantum Mechanics: A Modern Development by Ballentine

    Great book, that offers a few insights not found in other book. Not suitable as an introductory text.

    Propagator using Functional QFT

    You have to be careful here. You're probably using a coherent-state basis, which is a basis corresponding to eigenvalues of the field operators. This basis is overcomplete, so you need a compensating factor for this. Look at for instance Altland and Simons.

    2 dimensional chiral boson theory

    The chiral boson in 2D was introduced e.g. by Floreanini and Jackiw (see here: http://prl.aps.org/abstract/PRL/v59/i17/p1873_1 ). In particular eq. 20 is the Lagrangian of the 2D chiral boson. There is also a relativistic version I believe (or, at least, a more covoriant notation), which is I...

    Introductory Finance

    What area of finance are you interested in? One area frequently linked to more fancy math is that of financial derivatives, or more general the area of quantitative risks. Check out: http://www.markjoshi.com/RecommendedBooks.html More interested in a general exposé? Check out: Buchanan -- An...

    Book recommendations for Non-Equilibrium Statistical Physics

    There's a two-volume book by Toda, Kubo + third author. First part is on equilibrium, second one on non-equilibrium statistical mechanics. Great graduate texts.

    Geophysics vs. Medical Physics

    In Geophysics it's all about the data -- noise filtering, time series analysis, stuff like that. You do a lot of field work (from day trips to a whole month), but spent the majority of your remaining time processing this data. So expect a lot of data analysis, lots of programming and of course...

    Average Value of a Function

    The next quantity you can define to characterize a function or data set would be something like "the average deviation from the average". The way you define it is as: \frac{1}{b-a}\int_{a}^b f(x) (x - c) dx where c is the average value of f(x), defined by your integral. This expression is...

    Multivariable confluence hypergeometric function

    I'm looking for any kind of reference on a multivariable generalization of a (confluent) hypergeometric function. In particular, Horns list is a list of 34 two-variable hypergeometric functions, 20 of which are confluent. Then one of these has the following series expansion: \Phi_2(\beta...
