Interesting article this morning in Times science section, about film diva Hedy Lamarr. Did you know that (along with being "the most beautiful woman in the world") during WW 2, with composer-friend Georges Antheil, Lamarr developed a radio-jamming device based on randomly changing frequencies - they called it "frequency hopping" - which would utilize linked pairs of player piano scrolls - one in the ship, one in the torpedo? & that they patented this & took it to the Navy, which eventually classified it? & that the idea helped lead to aspects of internet & cellphone technology? & that Lamarr was given a Pioneer Award by the Electronic Frontier Foundation in 1997?
