Is it possible to get the forum to support LaTeX. Without it, it really limits a lot of the stuff you can post - especially if there is going to be a...
I wish sciforums supported LaTeX.
First of all, I understand that my "story" is A LOT different than faster than light travel. Im not claiming anything - I am merely trying to point...
If we had no perception of light - say humans evolved without eyes but we had ears. We would live in darkness with no idea what made us warm during...
Has anyone heard of p-adic numbers? The topic came up briefly the other day in my Number Theory lecture. However, we were not in a position to...
I thought you can prove the "speed" of light is constant by using Maxwell's equations - not a difficult calculation if I remember correctly...
Lethe!? I thought he was never coming back? I've always wanted to know what tensors are used for. Personally, I have never had to use them...
restrain? what restrain? :D Sorry ProCop, I simply had to answer it - it was such a cool puzzle. I liked how one of the ages was actually...
Alternatively if you had no idea you could do this from scratch. The puzzle must satisfy two equations: (1)... x + 21 = y (2)... 5(x+6) -...
Hehe! Thats a really good puzzle! Age of son: -9/12 (assuming 9 months until conception). Age of mother: 20.25yrs old After 6 years... Age...
There used to be a guy on this forums called Lethe. He was absolutely awesome in explaining this stuff to me when I had the same problem last year....
When I was 16, me and one of my friends had a competition to memorise pi. I got to ~225 and my friend got to 250. It was fun at first, I memorised...
This is what I don't get James R. The definition of the word irrational, means exactly what you said in your proof. Yet kriminal99 has been shown...
1/3 is defined to be 0.333... don't forget the ad infinitum. I don't think this is what infinitesimal means. You are defining infinitesimal by...
Yeah, sorry about that. I don't know why I typed that?? I guess I was trying to say decimals with recurring 9's (like 2.999... or 3.999...) are the...
Does anyone know how to prove that an operator is bounded. Here is a sample question. Let U, V and W be inner product spaces. Suppose that...
Okay, lets make it simpler. If you were 0, how far would you have to go to get to 1? 1 right! If you were 0.5, then you'd have to go 0.5 further to...
Every rational number can be represented as a fraction. It is a fact that 1 = 0.999... It can be proved easily by the 2nd method that Solo posted....
Notice that the function sin(1/x) oscillates between -1 and 1 and it does this more frequently as you approach 0. That is, no matter how close you go...
Of course not. I was just giving the long answer. I was hoping to also explain it numerically, but I didn't. Is my proof incorrect??
Separate names with a comma.
