Marc Maron: Mathematical Cure for Jealousy

I used to be jealous; Im not jealous anymore. And a miracle happened to me, because if youre jealous, its a cancer, its a plague on your spirit, it really is. And I actually cured jealousy in a very weird way -- I cured it with mathematics. And Im not a math person at all, but Ive been with my wife for about seven years, so we have had sex probably, Id like to think, like, 9 million times or, at least, 1,500. So, the way I figured it, if she goes out and screws some other guy once -- Im still winning.

Centre-pivot irrigator

In 1952, a U.S. patent for a "Self-Propelled Sprinkling Irrigating Apparatus" was issued to Frank L. Zybach of Strasburg, Colorado (No. 2,604,359). A centre-pivoted pipe supported on a series of water-piston-powered wheels rotates and sprinkles water on the crops.A control system ensures that each wheel advances at the correct rate. This is the now-familiar centre-pivot machine that waters large circles of crops in those areas of a country which have limited rainfall but have a supply of surface or well water. It provides irrigation for large areas of even closely-spaced crops for which irrigation ditches are not practical and wasteful of water, or that would be expensive to supply with full coverage with stationary sprinklers.«[Image: a modern example showing the sprinkler pipe carried above a series of large wheels.]
