Where Is My Goat?
There were these two guys out hiking when they came upon an old, abandoned mine shaft. Curious about its depth they threw in a pebble and waited for the sound of it striking the bottom, but they heard nothing. They went and got a bigger rock, threw it in and waited. Still nothing. They searched the area for something larger and came upon a railroad tie. With great difficulty, the two men carried it to the opening and threw it in. While waiting for it to hit bottom, a goat suddenly darted between them and leapt into the hole!
The guys were still standing there with astonished looks upon their faces from the actions of the goat when a man walked up to them. He asked them if they had seen a goat anywhere in the area and they said that one had just jumped into the mine shaft in front of them! The man replied, "Oh no. That couldn't be my goat, mine was tied to a railroad tie."

Andrew J. MoyerDied 17 Feb 1959 at age 59 (born 30 Nov 1899).Andrew Jackson Moyer was an American microbiologist who invented a method for mass-producing the antibiotic penicillin. While working for the US Agriculture Department laboratory (1940-57), he discovered a technique for antibiotic fermentation using continuous shaking of a culture broth of corn steep liquor (a by-product of the corn starch manufacturing process) and lactose. His method improved on prior methods producing 2 to 8 Oxford units/ml of broth, to in excess of 200 Oxford units/ml. By making possible the large-scale production of penicillin, the process is credited with saving thousands of lives during World War II. Corn steep liquor was adopted for other commercial fermentation processes making many other antibiotics, and the method is still in use today.« |
