Niccolò Fontana TartagliaDied 13 Dec 1557 (born 1499).Italian mathematician who originated the science of ballistics. His proper name was Niccolo Fontana although he is always known by his nickname, Tartaglia, which means the "stammerer." When the French sacked Brescia in 1512, soldiers killed his father and left young Tartaglia for dead with a sabre wound that cut his jaw and palate. In 1535, by winning a competition to solve cubic equations, he gained fame as the discoverer of the formula for their algebraic solution (which was published in Cardan's Ars Magna, 1545) Tartaglia wrote Nova Scientia (1537) on the application of mathematics to artillery fire. He described new ballistic methods and instruments, including the first firing tables. He was the first Italian translator and publisher of Euclid's Elements (1543). |
Old Josh was sat in his garden...
Old Josh was sat in his garden, sunbathing in the deck chair when he noticed his grand-son kneeling on the lawn with a worm. When he asked his grandson what he was doing, he found that he was trying to push the worm down the hole from which it came.
"If you can get that worm back in that hole I'll give you ten dollars," said Josh.
His grandson sat and thought for a moment, then rushed into the house. A few minutes later he returned with his mother's hair spray. He picked up the worm by one end and, as he let it hang down, he sprayed it all over with the hair spray. The spray set and the worm became stiff and hard. It was now easy to push the worm back in the hole. Josh was amazed. He gave the boy ten dollars, picked up the hair spray and went indoors.
About an hour later Josh came back into the garden and gave his grand-son another ten dollars.
"But grandpa," said the boy, "you've already given me the ten dollars you promised."
"That's from your grandma," said Josh.
