Introduction-
I learned in the introduction that I would only learn about inventions from a timespan of 200 years. I also learned that inventors face adversity and that a lot of times have to make patents and if he invents something that is already invented, and the other person already has a patent he has to pay the original inventor a fine. One other thing I learned is that if the people think that someone else’s invention or discovery is right and someone else makes a new invention or discovery the government might even protest that he is wrong.
