I am a geek and readily admit it. The other night on the ACH channel they had the program What History Forgot, and talked about actress Heddy Lamar and what a genesis she was. During World War II, Lamarr and composer George Antheil developed a radio guidance system for Allied torpedoes, which used spread spectrum and frequency hopping technology to defeat the threat of jamming by the Axis powers.
I was so awed by this information, and told my husband, thinking to surprise him. Yeah, he knew. He was in the army and was a munitions officer and a physicist. I didn't stump him. But he still can't find yeast in the kitchen cabinet.
