One day a teacher had a taste test with her students. She picked a little boy to do the first test. She blindfolded him, put a Hershey kiss in his mouth and asked, "Do you know what it is?
"No, I don't," said the little boy
"Okay, I'll give you a clue. It's the thing your daddy wants from your Mom before he goes to work."
Suddenly, a little girl at the back of the room yelled, "Spit it out! It's a piece of ass!"
Paul NiggliDied 13 Jan 1953 at age 64 (born 26 Jun 1888).Swiss mineralogist who originated the idea of a systematic deduction of the patterns in the internal structure of crystals by means of X-ray data. He supplied a complete outline of methods that have since been used to determine these patterns. There are 230 possible different internal patterns for different crystals. Because the patterns describe a three-dimensional arrangement, they are known as space groups. Niggli also developed a notation that described the individual space groups, and co-authored a definitive set of tables describing them. |
