So in my history class i am being asked to write an 5 page research paper on anything that has impacted American Society culturally, economocially, socially, etc. It can be on anything from baseball to jazz to the atomic bomb. It just has to have had a major impact on America between 1877 and 1990. I would like to do something physics related (since im planning on majoring in physics in college) but i dont know exactly how to specify my thesis. It cant just be on the evolution of physics over that time period because that's too broad, at the same time is has to have had a major impact on American Society. Any suggestions?
