Default Best solder free electrical connection

Come to think of it a lot of USoA technology was
borrowed from others (light bulbs, telephones,
computers, WWW, space flight, etc).


Where do you get this "information"?

light bulbs: The British love to point out that Swann had an incandescent
lamp before Edison. True. But it used an expensive platinum filament. Edison
came up with a cheap carbon filament -- and the electrical generation and
distribution system to back it up. (And let's not forget that the AC system
in use today was designed by a naturalized American citizen.)

telephones: The telephone is unquestionably an American invention.

computers: Although work was done in a number of countries (eg, Konrad Zuse
in Switzerland), the first large-scale electrical and electronic computers
were built in the US.

WWW: The Internet -- which the WWW is built over -- is an American
invention.

space flight: If you mean simply getting a rocket above the atmosphere, it
was likely first done by 'murcans. (I don't think the Germans got high
enough.)
