Are basic principles like those of Newton's laws of motion considered as physics axioms on which you expand to physics theorems? Where can I find a list of physics axioms?

XP is something I've studiously avoided. I have a neighbor with a question though. Normally when you right click the Start button the "Open" command is at the top of the popup list. In this case the order has somehow shifted and now the "Search" command is at the top of the list. This...

I need a list of primes up to at least 10^9 if possible. I don't want a program that will generate it as it will take too long. Does anyone know where on the net I can find a list that's already compiled? The largest I can find so far is 10^7. The list doesn't have to be fancy, just the primes...

Stanford/SLAC has been lax about maintaining the topcite review process. Some of our bets depend on the topcite report----the forecast polls we had last year were sometimes about trends in citation. Arivero has remedied the slackness of SLAC to some extent by compiling the 2005 topcite list...

we are fortunate to be introduced to several approaches for combining matter with a quantum spacetime---enough so there is actually a profusion of "quantum spacetime/matter" alternatives so we had better list the ones that have been introduced to us recently 1. Garrett Lisi 2. Torsten &...

Hi, I am a completely newb to the MIPS assembly language and I'm having a bit of trouble with this one procedure. Basically, i want to have the user enter in a list of numbers. The user can keep entering in numbers but when -999 is entered, the user cannot enter in anymore numbers. This list...
