Sue Over The Property


Did you know that heaven and hell are actually right next to each other? They are seperated by a big chain-link fence. Well, one day hell was having a big party and it got a little out of hand. God heard the ruckus and arrived to find his fence completely smashed by the wild partiers. He called the devil over and said "Look, Satan, you have to rebuild this fence." Satan agreed. The next day God noticed that the devil had completely rebuilt the fence...but it was 2 feet further into heaven than before.
"Satan!" beckoned God. "You have to take that fence down and put it back where it belongs!"
"Yeah? What if I don't?" replied the devil.
"I'll sue you if I have to," answered God.
"Sure," laughed Satan. "Where are you going to find a lawyer?"

Robert Goddard

Born 5 Oct 1882; died 10 Aug 1945 at age 62. Robert Hutchings Goddard was an American physicist, rocket engineer and inventor known as the “father of modern rocketry.”From age 17, Goddard was interested in rockets (1899) and by 1908 he conducted static tests with small solid-fuel rockets. He developed mathematical theory of rocket propulsion (1912) and proved that rockets would functioned in a vacuum for space flight (1915). During WW I, Goddard developed rocket weapons. He wrote A Method of Reaching Extreme Altitudes, in 1919. Over the following two decades he produced a number of large liquid-fuel rockets at his shop and rocket range at Roswell, N.M. During WW II he developed rocket-assisted takeoff of Navy carrier planes and variable-thrust liquid-fuel rocket motors. At the time of his death Goddard held 214 patents in rocketry.
