Nun of Your Business

While shopping in a food store, two nuns happened to pass by the beer, wine, and liquor section. One asked the other if she would like a beer. The second nun answered that, indeed, it would be very nice to have one, but that she would feel uncomfortable purchasing it. The first nun replied that she would handle it without a problem. She picked up a six-pack and took it to the cashier. The cashier was surprised, so the nun said, “This is for washing our hair. ”Without blinking an eye, the cashier reached under the counter and put a package of pretzel sticks in the bag with the beer. “The curlers are on me.”

William Fowler

Born 9 Aug 1911; died 14 Mar 1995 at age 83. William Alfred (Willy) Fowler was an American astrophysicist, who shared the Nobel Prize in Physics in 1983 for “his theoretical and experimental studies of the nuclear reactions of importance in the formation of the chemical elements in the universe.” He spent much of his life measuring the rates nuclear reactions of astrophysical interest, as in the interior of stars. From 1964, Fowler made theoretical calculations relating to supernovae, gravitational collapse, neutrinos, formation of light elements, and nucleocosmochronology. Fowler co-authored a paper, Synthesis of the Elements in Stars, (with Geoffrey and Margaret Burbidge and Fred Hoyle) which demonstrated how cosmic abundances of most nuclides (other than the lightest) could result from nuclear reactions in stars.«
