Why was it said that mastering quantum mechanics would give you the ability to change the world?
Mastering quantum mechanics can give you the ability to change the world because it's a very important scientific theory that involves all aspects of our daily lives. Quantum mechanics is the study of how matter moves, how they interact, and how they behave. It is very important for understanding many phenomena in nature. Mastering quantum mechanics could also help you solve many real-world problems, such as nuclear energy development, space exploration, new material development, and so on. The development of these fields is closely related to quantum mechanics, so mastering quantum mechanics can allow you to better serve society and promote the progress of human civilization. Quantum mechanics was a very esoteric scientific theory that required a lot of time and energy to study and research. However, if you can master it, you will be able to make an important contribution to human society and make our lives more convenient and beautiful.
