A few months ago on Radiolab, we did an hour on color, which included a segment on rainbow watching. We imagined a man, a dog, a sparrow and a butterfly all gazing at the same rainbow and we asked: How many colors does each see?

What if you put all 7 billion humans into one city, a city as dense as New York, with its towers and skyscrapers? How big would that 7 billion-sized city be? As big as New Jersey? Texas? Bigger? Are cities protecting wild spaces on the planet? We try a little experiment to find out.

Monty Python's John Cleese gives us a highly sophisticated, totally un-understandable, look at the human brain. The secret is, Cleese isn't speaking English. It sounds like English, but its nonsense. The closed caption English translation goes nuts, especially at the very end. It curses!
