Did you prove anything new and different? Are you even suggesting something?

Come on. That's just gummint claptrap. Everybody knows the Germans invented lasers in secret and Michelson had one of those. The laser technology was taken by the U.S. after WWII and then finally released as if it was a new idea in 1958 along with ICBMs, UFOs, fiber optics, transistors and all the other Nazi inventions that were gathered up in project LUSTY and related projects. When it comes to real conspiracies you guys are just babes in the woods.

Just one year for it to be a Nazi invention and given away to the USA for Michelson's birthday prezzie before the old chap croaked. The thing is, why didn't the Nazis invent the compact disc to go along with it, flood the market with cheap records and win the Eurovision Song Contest?

(Basically because they refused to work on it because it was "Jewish physics") Had they not been so ethnically shortsighted they'd have won the war and we'd all be speaking (singing) German now. :( Speaking of CDs I worked on a device that was a thin film disk written on by a laser back in the early 70s with some schoolmates of mine who had a patent on it. The patent was assigned to another company who retained the rights for data storage for point of sale use. My friends had all other rights. [basic idea was the disk would record all bad credit card numbers transmitted by radio overnight.They later went to just calling in by phone instead.] My pals kept trying to figure out what such a storage device would be good for if it wasn't for credit card numbers? They couldn't think of a thing! I just smiled and said nothing figuring if they couldn't figure it out, I sure as hell was not going to make them rich. Eventually others did a slightly different variation on the same idea for audio recording. Those clowns suffered from the same syndrome in that they couldn't think of using it for computer data storage either. Oh well, the smartest man in the universe [Bill Gates] couldn't figure out the internet might be useful either. |
