Write a reading reflection on the history of quantum mechanics

The reading reflection should be no more than 1000 words long.

Reading reflection prompts: What does the historical development of quantum mechanics reveal or illustrate about the nature of scientific progression? Quantum mechanics is widely described as a scientific revolution; so what does a scientific revolution look like? How does it look from our perspective as compared to how it looked by the people making it happen at the time? What drives a scientific revolution? Why did it need to happen?
