A trip to the movies...

For the first time in many years, an old man traveled from his rural town to the city to attend a movie.

After buying his ticket, he stopped at the concession stand to purchase some popcorn. As he handed the attendant $1.50, he couldn't help but comment, "The last time I went to the movies, popcorn was only 15 cents."

"Well, sir," the attendant replied with a grin, "You're really going to enjoy yourself this evening. We have sound now."

Robert Goddard

Died 10 Aug 1945 at age 62 (born 5 Oct 1882). 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.
