### Re: Things that don't amount to short enough titles [SOLUTIO

Here's the game: 3 4 5 6 x2 y3 5 6 y2 x0 5 6 x0 0 y4 6 0 0 y3 x5 0 0 x0 y4 0 0 0 x3 0 0 0 y2 0 0 0 x1 0 0 0 y0 See? Your opponent wins. All righty, would you like to explain your notation? We start with: 3 4 5 6 x2 y3 5 6 I guess this means you (x) begin by removing one from the first pile, then yo...

### That has more to do with biology than physics, of course.

We're made to hate comparable hot temperatures more than comparable cold temperatures, because they're more dangerous for us. This is because we mammals have pretty good means of warming up, but there's not much we can do to cool ourselves down. Our internal bits get devastated from a few degrees' d...

It's kind of hard to conceal a diagram, no? I guess you want another thread. Well whose obligation is it to post that thread? Mine?

Anyway, I did it.

Post solutions (and incorrect non-solutions that you mistakenly think are right) there!

### Snakes on a Plane solution thread (spoilers)

Solution thread for Snakes on a Plane . Here's the problem statement again: There are some positive number of snakes on a two-dimensional plane. Snakes can't overlap or cross each other, because they're on a plane. Every snake is touching exactly three other snakes - one with its snout, one with its...

### Re: Things that don't amount to short enough titles [SOLUTIO

We want to go first. For n piles, we have one pile of 3, (n-1) piles of 4, and m=(n-1)(n-2)/2 surplus beans. If m is even, we start by doing 3 -> 0. This leaves an even m and our opponent moving. If m is odd, we start by doing 3 -> 2. This leaves an even m (odd + the spare 2) and our opponent movin...

Because integration by parts isn't the way to solve this one? Generally speaking, integration by parts just produces another true statement. Sometimes the integral in that statement is simpler and you can solve the integral, but not always. Another great example is the integral of exp(x)sin(x)dx. Yo...

no snake touches itself? :lol: That isn't an explicit requirement, but I think you'll easily see that it's mandated by the other requirements. EDIT: Oops, I guess it is an explicit requirement. I don't think it was necessary, though. Maybe.... Well whatever. No snake touches itself, okay! Get your ...

### Snakes on a Plane

Here's one I made a couple of months ago in honor of my favorite movie from this summer, The Devil Wears Prada. There are some positive number of snakes on a two-dimensional plane. Snakes can't overlap or cross each other, because they're on a plane. Every snake is touching exactly three other snake...
