Unlucky Parachutist

A man is skydiving, enjoying his free-fall, when he realizes that he has reached the altitude where he must open his parachute. So he pulls on the rip cord, but nothing happens.

“No problem,” he says to himself, “I still have my emergency chute.” So he pulls the rip cord on his emergency parachute, and once again, nothing happens.

Now the man begins to panic. “What am I going to do?” he thinks, “I'm a goner!”

Just then he sees a man flying up from the earth toward him. He can't figure out where this man is coming from, or what he's doing, but he thinks to himself, “Maybe he can help me. If he can't, then I'm done for.”

When the man gets close enough to him, the skydiver cups his hands and shouts down, “Hey, do you know anything about parachutes?”

The other man replies, “No! Do you know anything about gas stoves?”

Charles Alfred Coulson

Born 13 Dec 1910; died 7 Jan 1974 at age 63. British theoretical chemist known for the application of molecular orbital theory to chemical bonding, the electronic structures of molecules and the concept of partial valency. He developed many mathematical techniques for solving chemical and physical problems. His molecular orbital theory treats a molecule as a whole, and extends atomic quantum theory with “allowed” states of electrons associated with two or more atomic nuclei. With this approach, he explained the structure of benzene and other conjugated systems, and using what he called partial valency, he described the bonding in such compounds as diborane. After writing on Waves (1941) and Electricity (1941), his book Valence (1952) was highly influential. He also wrote on reconciling scientific and religious views, believing religious faith was an essential in the pursuit of science.«
