This may be somewhat of an odd request, but I need a list of all physics formulas in the broad subject of physics (probably just into to physics level), preferably in plaintext. Anyone know where I can get this? I'm not looking to study it, so I'm not looking for a list of nicely categorized...

Is there such a list somewhere in the www? My motives are pure... :!)

Does anyone know where I can find a list of Christoffel Symbols for various metrics? Metrics of general forms, as well as famous ones like Schwarzschild and Robertson-Walker? Yes, I can calculate them all if I really need to, but it's pretty tedious.

Is it safe to assume that the absolute value of sin x is greater than zero for all positive integer values of x? I have no real experience in number theory, and I don't know if you can say that there are no irrational numbers in an infinite list of integers.

Hi there! Just asking for a website with a detailed list of winter/summer schools, workshops and so on for the full present year, related with quantum gravity. Thank you very much in advance.

http://rjlipton.wordpress.com/2009/12/26/mathematical-embarrassments/: i didn't think the invariant subspace problem would be an embarrassment. i guess it's not all that hard for finite dimensions. only one person mentioned goldbach's conjecture, & nobody said anything about perfect numbers...

If I have a .TXT file with comma-separated e-mail addresses, is there some way that I can quickly send an e-mail out with all of them in the BCC field? For example, could this be done from the command line in Linux (Ubuntu 9.04)? Is there some way that I could have the contents of another .TXT...

The most recent version of the theorem, as stated by Nikonorov in 2004 Let G a connected compact semisimple Lie group, which acts almost effectively on a seven-dimensional simply-connected homogeneous space M^7=G/H. If (G/H,\rho) is a homogeneous Einstein manifold, then it is either a symmetric...

Hi everyone, I have a folder of Vietnamese songs (files). The file names are in Vietnamese. I used a VB6 program to create a list of file names and output them to MS-word. The program won't understand the Vietnamese characters, suc as ^, ., ~..., so it was represented by question marks...

How extensive is your "To Do" list? I have more items on my list than I could possibly complete in my lifetime, but it's mostly for keeping busy. Prioritised by the more important things to get done, I think a decade or two will see fulfilment. So I was curious about to what extent everyone...

I couldn't find list of functions or operators. My naive approch was to list the elements of Symbol as Symbol seems to be the Head of all functions--but this didn't work. Is there a way for Mathematica to generate this?

Hey guys, I'm trying to implement a linked list in C, with each node carrying fields from a text file. The problem is that whatever was the last line read from the text file gets placed into every single node. Even more strange is that when I add an additional node outside of the while loop it...

So my algorithm compares a node that needs to be inserted with the current linked list set. it goes from first (which contains the lowest integer) and moves forward until it hits null or when the key trying to be inserted is no longer greater than the nodes being compared to. My input of 23...
