Annotation
Thank your Hollywood stars that Hedy Lamarr, who trained as an engineer, invented spread-spectrum radio with avant-garde composer George Antheil. Allowing the rapid switch of communications signals through a range of frequencies, spread-spectrum radio makes cell phones, GPS, and radio-guided torpedoes possible. I've heard this story but suspect that multiaward winner Rhodes will make it even better.
