At the Airspeed Velocity of an Unladen Swallow

I don’t normally go for all that geometrical beauty stuff, but this is some damn pretty mathematical agitprop.

Math isn't just for the birds. This blog is dedicated to mathematical beauty, humor, quirk, mystery, and everything beyond and between.

The Pigeon Hole Principle:

If m pigeons are placed in n pigeonholes and m > n, then at least one hole must contain at least two pigeons.

The name was chosen because it has a nice ring to it and is easy to remember. If you'd like to explore some pigeonhole problems, try adding /tagged/pigeonholeproblem to the end of our URL.
