You said about Nikola Tesla, he is one of my favorite scientists, I love him very much, who is now removed from science. The preparation you want Tesla to make is actually correct. You said about electricity, radio waves and the wheel. In fact, if these three did not exist, we would be in a lot of trouble. Had to read present easily contribution of science we can never deny science has taken us and our community far and hope to take it further thank you for presenting such a nice post.
