Signal amplification was going on way before transistors with vacuum tubes which also give a 180 degree phase shift. I think something happened in the desert of NM and the government won't tell us what it was and we got the benefit of it.Everything seems so simple after the fact. The fact is that rocks and wires had existed a long time before 1947 and they "invented" it just a short time after absolutely nothing landed in Roswell, New Mexico. Its one of those things we will probably never know the truth of. For those of you who believe there was no Roswell cover up, I cannot relate to the Disney World faith you have in our government. I don't share that. I question the governments motives and wish more people did the same. For those who defend the government without question, it scares me.
The principles of the transistor were first patented in 1925. A primitive version was first built in 1942. It's a key component in signal amplification. To claim that human beings aren't smart enough to figure it out on their own (especially after decades of electronics research) is frankly insulting.
What does this have to do with "The Government" supposedly faking the moon landings? Is your faith in your position so weak that you have to change the subject and insult the people who understand the facts of science & history? I for one would still love to hear about how "The Government" found it to be better / easier / cheaper to do so.
Oh, and "The Government's" motives for the Space Race are well known and thoroughly documented in multiple media.
Research had been going into solid-state electronics for YEARS before the first practical silicon transistor was constructed in 1954.
