Background : I was recently reminded of an abandoned project of mine that is related to railways and "green energy," so I started doing some Internet searches to see if there are any similar projects in the world. To my surprise, the project was already carried out by another institution. Even more surprising was that the project was done almost at the same time that I had the idea.
My question is:
Does having the same education/environment for a population make the same invention inevitable and predictable at some moment among that population?
If yes, no wonder why there is so much claims for the same invention at the same time that may come from different places across the world.
