1. ### I EPR and Non-Locality - For and Against

I think this pretty succinctly hits the nail on the head: "local" by itself is a word that people learn by association from other people, seeing examples of things called "local" and others "nonlocal". So arguing about which box quantum physics should be put into is not interesting by itself...
2. ### Python IDLE and print function...

More precisely, print() prints the default "display" or "aesthetic" string representation of its argument, as returned by calling str() on it. By contrast, Python's interactive interpreter evaluates the expression you give it and tries to display it in source form, as returned by the repr()...
3. ### LaTeX Wide equation in Revtex 4.2 is overlapping with other content

Okay, that makes sense. I don't know for sure, but it may just have been a problem with RevTeX. Personally I usually avoid using RevTeX when I can since it seems to have trouble with placement of things not unlike what you've seen, particularly when using the pra/prb/etc. options. RevTeX with...

11. ### I A (probably) simple question about Bell's paper

You don't need to do any calculus. You're averaging ##\text{sign} \, \boldsymbol{\lambda} \cdot \boldsymbol{a}'## over vectors ##\boldsymbol{\lambda}## that satisfy ##\boldsymbol{\lambda} \cdot \boldsymbol{p} > 0## for some given vectors ##\boldsymbol{a}'## and ##\boldsymbol{p}##. ##\text{sign}...
12. ### Second programming language to get under the belt: python vs C

Why not learn both? It's not like it would necessarily take all that much of your time. Python is among the easiest programming languages to pick up and start using and has lots of libraries available for getting things done. C is much lower level, so less practical for many purposes, but (as...
13. ### C/++/# Best resources to learn C++ (free)

Herbert Schildt's books have a bad reputation among people knowledgeable about C and C++. The 'bullshildt' is named after him. You can find negative expert reviews of Schildt's books on the ACCU (Association of C and C++ Users) website. The USENET alt.comp.lang.learn.c-c++ FAQ (scroll down to...
14. ### When Calculators lie will anyone notice?

Emacs also includes an RPN calculator (calc) in its standard distribution. I haven't really used it but the feature list seems quite impressive for a package included in what is ostensibly a text editor.
15. ### When Calculators lie will anyone notice?

I don't think you're limited for choice if you want to use RPN on a computer. The dc calculator (one of the traditional Unix command-line utilities) and Forth programming language are both stack-based and use RPN notation. I am not sure this is so useful in a programming language though. RPN to...
