Radar

In 1934, the first test of a practical radar apparatus was made by Rudolf Kuhnold in Kiel Harbour, Germany, Chief of the German Navy Signals Research Department. His 700-watt transmitter worked on a frequency of 600 megacycles, had a receiver and had disk reflectors. It received echoes from signals bounced off the battleship Hesse, anchored 600 yds away. In an October test, it picked up echoes from a ship seven miles away. Radar was to be an important asset in the coming WW II, but ironically it was the U.S. and Great Britain, that took Kuhnold's pioneering work and developed it into a reliable detection system. Kuhnold may thus be described as the man who won the Battle of Britain for the English!

Grandmother started walking

'My grandmother started walking five miles a day when she was 60. She's 97 now and we don't know where the hell she is.'

Ellen DeGeneres (January 26 1958-)
