Martha Kelly: Preparing for Office Work

Its been a couple of years since I actually worked in an office, so I thought I should do something to prepare to get back into the typing, filing and phone answering, and what not. So what I did was I had a friend of mine go with me down to the local swimming pool, and I had him tie me up in a burlap sack and sink me to the bottom of the pool. And then just as I was about to suffocate, he yanked me up and gave me a lunch break.

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.
