comment Do the equations used in Stargate make sense or are they gibberish?
I know the equation you are talking about (the one Chloe solved). From what I remember it was a simple integral (I didn't pay too close attention so it may have been improperly written) that any 1st year calculus student can solve.

comment Identity involving Euler's totient function: $\sum \limits_{k=1}^n \left\lfloor \frac{n}{k} \right\rfloor \varphi(k) = \frac{n(n+1)}{2}$
What immediately jumps out is how such a complicated function like the totient function has an identity involving the simple summation of integers 1 to n. Seems like a good way to prove it is to show that the expression inside the sum is a "rearrangement" of the sequence of integers 1 to n

comment Are Continuous Functions Always Differentiable?
As the last American president demonstrated, every potential threat deserves maximum military action.

comment The Hangman's Noose - A Logical Paradox
I understand that its an open question and that there is much debate on the topic, no reason not to extend the debate to here.

comment Coloring the faces of a hypercube
The question was really about extending Burnside's lemma to a higher dimensional figure. How would one answer the same question, but about a hypercube.

comment Taking Seats on a Plane
This is a good intuitive way to think about it. A formal proof is too heavy for a over-a-cup-of-coffee discussion, this is just right. I'll give you the credit since nobody seems to want to take a shot at the physical application

Thanks, very detailed explanation.
