High Monkey

A monkey is sitting in a tree smoking a joint when a lizard walks past and looks up and says to the monkey “Hey! What are you doing?”
The monkey says “Smoking a joint, come up and have some.”
So the lizard climbs up and sits next to the monkey and they share a joint. After a while, the lizard says his mouth is ‘dry’ and is going to get a drink from the river.
The lizard climbs down the tree, walks thru the jungle to the river and leans over the river to get his drink. The lizard is so stoned that he leans too far over and falls into the river.
A Crocodile sees this and swims over to the lizard and helps him to the side, then asks the lizard, “What’s the matter with you?”
The lizard explains to the crocodile that he was sitting smoking a joint with a monkey in a tree, got too stoned and then fell into the river while taking a drink.
The crocodile says he has to check this out and walks into the jungle, finds the tree where the monkey is sitting, finishing a joint. He looks up and says “Hey you!”
The Monkey looks down and says, “Duuuuuuuuuude…….how much water did you drink?!”

Pafnuty Lvovich Chebyshev

Born 16 May 1821; died 8 Dec 1894 at age 73. Russian mathematician who founded the St. Petersburg mathematical school (sometimes called the Chebyshev school), who is remembered primarily for his work on the theory of prime numbers, including the determination of the number of primes not exceeding a given number. He wrote about many subjects, including the theory of congruences in 1849, probability theory, quadratic forms, orthogonal functions, the theory of integrals, the construction of maps, and the calculation of geometric volumes. Chebyshev was also interested in mechanics and studied the problems involved in converting rotary motion into rectilinear motion by mechanical coupling. The Chebyshev parallel motion is three linked bars approximating rectilinear motion.[Old style dates: Born 4 May 1821; died 26 Nov 1894]
