Re: Philosophies That Underpin Science

I think Francis Bacon would be a good place to start. And what's with this google stuff ... books are better.

Also, you might find something of use in Thomas S. Kuhn's Structure of Scientific Revolutions.

Re: Need suggestions for college dorm prank

I always found the capacitor and the 9V battery shoved under the door at 4am always worked good. Also, tinea powder in the pedestal fan. Vaseline on the doorknob works good when they come home drunk. pardon my ignorance, but I hadn't heard of the capacitor and 9v one, could you explain it? and I do...

Re: Question(s) on triangle geometry.

Do you know of a way that is compass and straightedge compatible? Check out Euclid's Elements. He did a lot of work with a compass and a straightedge and derived a whole heap of mathematics from only a few axioms. I say this because the problem posed reminds me of problems one of my Professors used...

Re: War-is it ever justified?

If I may be so bold, I wish to contribute some theory on Just War. In order to justify going to war, the principles of Jus ad bellum are to be observed: Proper Authority: The country going to war with another must have the proper authority to do so. This alludes to the UN. Just Cause: Self Defence o...

Re: Ore's Theorem and Hamiltonian Graphs

You will always have a vertex of degree 2 because what is left over when you remove the two edges and the vertex is always a complete graph n-1 regular. The graph K_n is a subgraph as is the vertex of degree 2, and we know K_n where n>=3 are Hamiltonian. Chucking it all together satisfies Ore's Theo...

Re: Iterated Function

This doesn't look right. If this is an iterated function then aren't we talking about discrete dynamics? Or am I confusing your notation? If so, you have: For instance, I have s(n+1) = 2s(n) + 2^n and s(0) = 0 To me, this looks like a first order linear difference equation, that is if you meant to w...

Re: Ore's Theorem and Hamiltonian Graphs

I thought about this but I think you went about it a different way. Given that the number of edges is 1/2(n-1)(n-2) + 2 for n vertices, drawing the first few shapes leads to an interesting pattern. Draw one vertex of degree 2 and what remains is in fact the shapes of Kn, the complete graphs. Suddenl...

Ore's Theorem and Hamiltonian Graphs

A question for the learned: Let G be a simple connected graph with n vertices and \frac {1} {2} (n-1)(n-2) + 2 edges. Use Ore's Theorem to prove that G is Hamiltonian. Now, Ore's Theorem states: Let G be a simple connected graph with n vertices, where n \ge \ 3 and d(v) + d&#...

Re: Books you like that no one else has heard of

Dust and Ashes by Anatoli Rybakov.

Set in Stalinist Russia and follows the lives of some young people living on the Arbat. This is the third book in a trilogy and finds them caught in a war.

Beautiful ending.

Re: REALLY Annoying Misconceptions

You are all right ... sort of. :wink: Fuel tanks (at least those in cars) don't usually have lines running straight out of the bottom. They tend to drain very low out of the side of a tank. If they do feed the system from the bottom (I'm talking right from the bottom), you'll generally find a stand ...

Re: Australian School to Redefine "cheating"

also, i don't think rote learning deserves as bad a rap as it gets. i'm just quietly hoping either (1) everyone here dissing it either just takes it for granted that they can calculate 12x12 without a calculator, or (2) the ones who see value in rote learning are sitting this one out. I have to adm...
