A President Visits an Elementary School

After delivering a speech at an elementary school, the president lets the kids ask a few questions. One little boy, Joe raises his hand and asks, “How come you invaded Iraq without the support of the United Nations?”
Just as the president begins to answer, the recess bell rings and he says they’ll continue afterward. 25 minutes later the kids come back to class.
“Where were we?” says the president. “Oh, yes… do you kids have any questions?”
Another boy raises his hand and says, “I have three questions: First, why did you invade Iraq without support from the U.N.? Second, why did the recess bell go off 30 minutes early? And third, where is my buddy Joe?”

Henri Braconnot

Born 29 May 1781; died 13 Jan 1855 at age 73.French naturalist and chemist known for isolating glucose, a simple sugar, directly from such plant material as sawdust, linen or bark by boiling them with acid (1819). Previously, glucose had only been derived from starch. In 1811, he was the first to find fungtine - in mushrooms. (It was named chitin in the 1830's when it was also isolated in insects.) Chitin is one of the most abundant polysaccharides found in nature. In 1832, Braconnot prepared “xyloidine”by treating starch, sawdust, and cotton with nitric acid. He found that this material was soluble in wood vinegar and attempted to make coatings, films, and shaped articles from it. This was an early discovery preceding the work of other scientists with nitrocellulose that led to the advent of plastics and rayon.
