A cocky State Highways em...


A cocky State Highways employee stopped at a farm and talked with an old farmer. He told the farmer, "I need to inspect your farm for a possible new road."

The old farmer said, "OK, but don't go in that field." The Highways employee said, "I have the authority of the State Government to go where I want. See this card? I am allowed to go wherever I wish on farm land."

So the old farmer went about his farm chores.

Later, he heard loud screams and saw the State Highways employee running for the fence and close behind was the farmer's prize bull. The bull was madder than a nest full of hornets and the bull was gaining on the employee at every step!!

The old farmer called out, "Show him your card!!"

Arne Tiselius

Died 29 Oct 1971 at age 69 (born 10 Aug 1902). Arne Wilhelm Kaurin Tiselius was a Swedish biochemist who won the Nobel Prize for Chemistry in 1948 for his work on electrophoresis and other new methods of separating and detecting colloids and serum proteins. In electrophoresis - a method of separating chemically similar charged colloids - an electrical field is applied to the sample, and particles with different sizes migrate at different rates to the pole of opposite charge, enabling them to be detected and identified. Using the technique on blood serum Tiselius confirmed the existence of four different groups of proteins - albumins and alpha, beta, and gamma globulins. Tiselius also conducted work on chromatography (from 1940) and partition and gel filtration (from the late 1950s).
