> Some experts were not to bright in the military. Hedy Lamarr invented a way to guide torpedo,s. That could not be blocked. The Navy experts laughed at her. She gave us cell phones and many other things based on her invention.
Although Hedy Lamarr did patent a technique we now call "spread-spectrum communications", her contributions to that technology are overstated. Her invention was not practical to implement with 1940s technology. Interestingly, modern remotely-guided torpedoes are not radio-controlled but rather wire-guided. Not only are wire-guided torpedoes and missiles virtually jam-proof, wire guidance could have been implemented in the 1940s.
