An engineer was crossing a roa...

An engineer was crossing a road one day when a frog called out to him and said, "If you kiss me, I'll turn into a beautiful princess."He bent over, picked up the frog and put it in his pocket.
The frog spoke up again and said, "If you kiss me and turn me back into a beautiful princess, I will stay with you for one week."
The engineer took the frog out of his pocket, smiled at it and returned it to the pocket.
The frog then cried out, "If you kiss me and turn me back into a princess, I'll stay with you and do ANYTHING you want."
Again the engineer took the frog out, smiled at it and put it back into his pocket.
Finally, the frog asked, "What is the matter? I've told you I'm a beautiful princess, that I'll stay with you for a week and do anything you want. Why won't you kiss me?"
The engineer said, "Look I'm an engineer.
I don't have time for a girlfriend, but a talking frog, now that's cool."

Heinrich Otto Wieland

Born 4 Jun 1877; died 5 Aug 1957 at age 80.German chemist, winner of the 1927 Nobel Prize for Chemistry for his studies of steroid chemistry in which he determined the molecular structure of bile acids. He is also noted for studying the conversion of food into energy. In 1912, he began work on bile acids, secretions of the liver known for the best part of a century to consist of a large number of substances. He studied three of them: cholic acid, deoxycholic acid, and lithocholic acid, finding that they were all steroids, very similar to each other, and all convertible into cholanic acid. After 1921, he studied some curious alkaloids including toxiferin (curare's active ingredient), bufotalin (in venom from toads), and phalloidine and amatine (poisonous ingredients in the deadly amanita mushroom).
