Doug Mellard: Prophylactics

I remember one point, this older gentleman asked me for some prophylactics, and at that time, my sexual vocabulary wasnt that great, you know. So, Im checking my word bank for the closest thing I have to prophylactics. Closest thing I got -- pterodactyls. I was all confused. I was like, Excuse me, sir, I hate to break it to you, but those things have been extinct for 65 million years.

Rudolf Wolf

Died 6 Dec 1893 at age 77 (born 7 Jul 1816).Swiss astronomer and astronomical historian. Wolf's main contribution was the discovery of the 11 year sunspot cycle and he was the codiscoverer of its connection with geomagnetic activity on Earth. In 1849 he devised a system now known as Wolf's sunspot numbers. This system is still in use for studying solar activity by counting sunspots and sunspot groups. In mathematics, Wolf wrote on prime number theory and geometry, then later on probability and statistics - a long paper discussed Buffon's needle experiment. He estimated πby Monte Carlo methods.
