Fractal images are so complex that there’s an entire area of mathematics specialising in them. However, the complex fractal image above comes from a single, simple equation.

Humour and sudden shocks are also complex, since they both depend on substantial knowledge about the world and about human behaviour, but, like fractals, the key to them comes from a very simple underlying mechanism. Here’s what it looks like. It’s called the Necker cube.

Quote for the day

We trained hard . . . but it seemed that every time we were beginning to form up into teams we would be reorganized.

The link is to an article by Jim Reeds, who found that the quote didn’t appear anywhere in the works of Petronius Arbiter, and was probably invented by Robert Townsend in Up the Organization (Knopf, New York, 1970).

Townsend also gave the world the following quote in the same book:

“And God created the Organization and gave it dominion over man…

Genesis 1, 30A, Subparagraph VII”
