Walk across the lake
At a family gathering, Fred's father, grandfather, and great-grandfather bragged that they had all been able to walk on water to the bar across the lake for their first legal drinks. So when Fred's 21st birthday came around, he rowed out to the center of the lake, stepped out of the boat, and nearly drowned. Fred climbed back in and went to see his grandmother.
"Grandma," he said, "it's my 21st birthday, so why can't I walk across the lake like my father, his father, and his father before him?"
Granny looked kindly into Fred's eyes and said, "Because they were all born in January, and you were born in August."

Hermann OberthBorn 25 Jun 1894; flourished 29 Dec 1989 at age 95.Hermann Julius Oberth was an Austro-German rocket engineer was a German scientist who was one of three founders of space flight (with Tsiolkovsky and Goddard). After injury in WWI, he drafted a proposal for a long-range, liquid-propellant rocket, which the War Ministry dismissed as fanciful. Even his Ph.D. dissertation on his rocket design was rejected by the University of Heidelberg. When he published it as Die Rakete zu den Planetenräumen (1923; “The Rocket into Interplanetary Space”) he gained recognition for its mathematical analysis of the rocket speed that would allow it to escape Earth's gravitational pull. He received a Romanian patent in 1931 for a liquid-propellant rocket design. His first such rocket was launched 7 May 1931, near Berlin.« |
