It kinda of surprises me that you would ask that question. Edison ran electricity through 10,000 different materials in a vaccum. That is why he later went on to invent the radio, phonograph, movie camera to name a few. They were all a product of his 10,000 "failed" attempts.Nathan Poe said:A good deal of Edison's success came through trial and error, as most scientific achievements are. Edison literally went through over 10,000 different designs for the light bulb, none of which worked.
Do you suppose he just cobbled things together at random, or did he actually learn from his mistakes?
Before science ever got involved, we had a TV, Radio, Photograph, Movie Camera, Telephone, to name a few. What science gave us was the transister, and later the micro processor.
The first transistor radios came out when I was about 12 years old. We thought it was neat that they figured out a way to make the radio smaller, but the sound quality was no wear near as good as the sound quality from vaccum tubes at first. Later on, they began to use filters to remove the static and a lot of the noise.
The building I live in is over 100 years old. It was "moderized" about 50 years ago, when my dad bought it. There really have been no substantial changes made in the last 50 years. Just maintaince. So the only real change is in telecommunications, where multiple people can get involved in a conversation at the same time. But that does not take a computer. In fact like I said, telecommunications was started up by hobby clubs long before Bill Gates, IBM and modern science got involved in it.
It really is little more than a party line with a keyboard and a storage devise, to store a message so everyone can read it. Science really did not get involved until computer were used for much more complex tasks than that.
