Re: Building a Gaming Desktop

It's been brought to my attention I can get Corsair Vengeance Pro 16GB (2 x 8GB) DDR3-2400 Memory for the same or cheaper price as DDR3-1600 or 1866 (as I have above). However, as far as I can tell, DDR3-2400 ram operates at 1.65 volts versus the CPU recommended maximum of 1.5V+5% (1.575V). Googling...

Thank you for the insights, I'll certainly look into 6th gen stuff, and give consideration to the R9 390x as an alternative to the 970, especially given they (the GPUs) appear to be roughly the same price.

Building a Gaming Desktop

So after clawing every bit off use out of my ~10 yo desktop, it's at the point where modern web apps can cause it to cry and I can't play most modern games even on minimum settings, so I'm finally biting the bullet and looking to drop in the ballpark of $1500 (not a strict budget) to put together a ...

Re: Prove by induction 3^n < (n+2)!

This may or may not be relevant to the case at hand (I just woke up and skimmed it), but some people consider N (the natural numbers) to be positive integers (1, 2, 3, ...) while others consider N to be the non-negative integers (0, 1, 2, ...).

If A asks if B knows the numbers and B says yes, then it must mean that a*b=1=a=b or that a*b=p where p is a prime, implying the numbers ...

Re: On friction

I would also be wary of using m to represent both meters (as in meters per second) and mass at the same time. Use uppercase M for the mass to limit the potential of confusing yourself (although as mentioned, just using g and similar with the dimensions built in until the end can avoid that problem).
