Your dog bite?

There was a hound dog laying in the yard and an old geezer in overalls was sitting on the porch.

"Excuse me, sir, but does your dog bite?" the tourist asked.

The old man looked up over his newspaper and replied, "Nope."

As soon as the tourist stepped out of his car, the dog began snarling and growling, and then attacked both his arms and legs. As the tourist flailed around in the dust, he yelled, "I thought you said your dog didn't bite!"

The old man muttered, "Ain't my dog."

Nikolay Ivanovich Lobachevsky

Died 24 Feb 1856 at age 63 (born 1 Dec 1792). Russian mathematician who, with János Bolyai of Hungary, is considered the founder of non-Euclidean geometry. Lobachevsky constructed and studied a type of geometry in which Euclid's parallel postulate is false (the postulate states that through a point not on a certain line only one line can be drawn not meeting the first line). This was not well received at first, but his greatest vindication came with the advent of Einstein's theory of relativity when it was demonstrated experimentally that the geometry of space is not described by Euclid's geometry. Apart from geometry, Lobachevsky also did important work in the theory of infinite series, algebraic equations, integral calculus, and probabilty.[EB gives New Style: born 1 Dec 1792, died 24 Feb 1856. (Old Style: 20 Nov 1792, died 12 Feb 1856). DSB>give birth as 2 Dec 1792.]
