Konstantin Eduardovich Tsiolkovsky

Died 19 Sep 1935 at age 78 (born 17 Sep 1857). Russian pioneer space theorist who, while a provincial Russian schoolteacher, worked out many of the principles of space travel. In 1883, he noted that a vehicle in space would travel in the opposite direction to gas that it emitted, and was the first to seriously propose this method propulsion in space travel. He wrote various papers, including the 1903 article “Exploration of Space with Reactive Devices.” The engineering equations he derived included parameters such as specific impulse, thrust coefficient and area ratio. He established that the most efficient chemical combination would be that of liquid hydrogen and liquid oxygen. He was later recognized by the Soviet Union as the “father of cosmonautics.” He also built the first wind tunnel.«

A man and a woman were asleep...

A man and a woman were asleep like two innocent babies.
Suddenly, at 3 o'clock in the morning, a loud noise came from outside. The woman, groggy and bewildered, jumped up from the bed and yelled at the man, "Holy crap! That must be my husband!"
So the man jumped out of the bed scared and naked and jumped out the window. He smashed himself on the ground, ran through a thorn bush and to his car as fast as he could go.
A few minutes later he returned and went up to the bedroom and screamed at the woman, "I AM your husband!"
The woman yelled back, "Yeah, then why were you running?"
