Two cows....

Two cows were chatting over the fence between their fields. The first cow said, "I tell you, this mad-cow-disease is really pretty scary. They say it is spreading fast; I heard it hit some cows down on the Johnson Farm."

The other cow replied, "Ah, I ain't worried, it won't affect us ducks."

Jeremias B. Richter

Born 10 Mar 1762; died 4 Apr 1807 at age 45.Jeremias Benjamin Richter was a German chemist who discovered the law of equivalent proportions. He studied chemistry in his spare time while in the Prussian army (1778-1785) and afterwards while earning a Ph.D. in mathematics (1789). Richter was much influenced by Immanuel Kant, whose lectures he may have attended, in the contention that science is applied mathematics. Richter looked for mathematical relationships in chemisty, convinced that substances reacted with each other in fixed proportions. He showed such a relationship when acids and bases neutralize to produce salts (1791). Thus he was the first to establish stoichiometry, which became the basis of quantitative chemical analysis. He died of tuberculosis at age 45 years.
