Just so we're all clear on this: I answered first, so I won. :p
a_n=0 for all n\in\mathbb{N}. :-D
That's what I meant: There are two qualitatively different types of infinities in QFT. There are those you can renormalize and those you can't....
Don't we? Aren't some infinities in QFT "sick" infinities and others not? For example, a logarithmic divergence can be dealt with but a quadratic...
No it won't. The speed of light is 186,000 miles per second. Given that there are 3600 seconds in an hour, 24 hours in a day, and 365 days in a year...
I don't know what you're talking about. I always swat the little bastard on the first try. :p
Here's one from quantum mechanics. In the 1D harmonic oscillator problem we define the creation operator to be, in appropriately chosen units,...
No, but if you weigh the same as a duck then you must be made of wood, in which case you must be a witch.
No, you're not missing anything. The correct answer is indeed 23,976. promethus, the sum is found as follows. \sum_{y=1}^{36}\sum_{x=1}^{36}...
Yes, one should. There is no "interval" from 2/3 pi to 1/3 pi. The left enpoint always goes on the left. ;)
Ain't that just like a sciforumer, bringing a knife to a gunfight. [IMG]
That's a gross oversimplification. That would be like asking, "Isn't sciforums little more than an AOL chatroom where any crackpot can say whatever...
That's a shame, because them's good vittles.
Medium 2? Is there some diagram that would make this question make sense?
OK well in that case, you've got to find the subspace that simultaneously satisfies the requirements for membership in both of the subspaces. *U...
Do you mean "intersection"?
Of course proof by negation is valid. But whether you're doing a direct proof or an indirect proof, if you run a false premise through a valid...
None of this has anything to do with the idea of "free energy".
So what? Right, millions of years. Not for eternity. That's the whole point. It isn't really creating energy. It is releasing the energy...
Yes, but the energy isn't free. The sun will eventually consume its fuel and die, just like every other star.
Separate names with a comma.
