WiFi

Having got me a laptop with WiFi connectivity, I figured I should know something about how it works ... so I google and read about direct-sequence spread spectrum (DSSS) and other spread-spectrum communication techniques. Huh? I got a headache after reading for five minutes. Further googling and I find that (gulp!) Hedy Lamarr co-invented such a scheme (and had a 1942 U.S. patent). Aw ... c'mon. If that actress can devise such a scheme surely I can understand it, eh? Gimme a day or three
