Interesting Numbers
If there were uninteresting numbers, there would be a smallest uninteresting number, which, by its virtue of being the smallest uninteresting number, would be interesting.

If everything when it occupies an equal space is at rest, and if that which is in locomotion is always occupying such a space at any moment, the flying arrow is therefore motionless.

Maxwell’s Demon
Imagine an insulated container divided by a wall. In that wall is a trap door. Controlling the door is a demon who can see the speeds of the molecules that comprise the gas that fills the container. As the faster molecules rush toward the door, the demon opens it, letting the speedy molecules into one side of the container. Likewise, when slower molecules approach the door the Demon opens it, trapping the slow molecules on the opposite side of the container from the fast molecules. In this way one side of the container becomes gradually warmer and the other side gradually cooler.
Has the demon thwarted the Second Law of Thermodynamics?
