According to source 3 (In Praise Of Careful Science) although it is fun to think about how a bump on the head from an apple changed our understanding of gravity, it really is less fun. Now from my last sentence you can see that this was just a coincidence, a person sitting under a tree and an apple falls on his head and now we know about his great discovery of gravity. Most of the time, scientists work for decades and make very few mistakes. Most mistakes made by scientist cause problems, not progress. If it was that easy to discover scientists would not waste decades to find about new technology and other things. In paragraph 19 the passage says '' Scientist John Denker says that many ''big discoveries'' were actually …show more content…
Then you experiment stuff many times until you get the results you want. After that other scientists do the same experiment to get the same results as you. Years of work is done and then the big discovery comes and people are surprised from your discovery but they don't know how many years of hard work have you done to discover a new thing. Scintist Denker describes how magnetrons and radar were discovered. The scientists tried not to make any mistakes. When they announced the new discovery, Percy Spencer accidently discovered that magnetron's property for heating food. That moment made him a great scientist and all the years of careful science was credited to
