Kittens

A three-year-old went with his dad to see a litter of kittens. On returning home, he breathlessly informed his mother there were two boy kittens and two girl kittens.

"How did you know?" his mother asked.

"Daddy picked them up and looked underneath," he replied. "I think it was printed on the bottom."

Paul Niggli

Died 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.
