Did you see the movie ”Oppenheimer ” ？ I was very surprised that many Americans have seen it , because it is not patriotic. I'm sure that Trump supporters have not seen it. Oppenheimer 's anguish is very right. The US is naivete or inexperienced in getting damages of domestic wars . It has not been attacked in the homeland by a hostile army , or bombed . Only the small and isolated island was bombed with a few casualties. Main European countries have been attacked and bombed enough in ww2. Japan has got the biggest casualties by nuclear bombs in 1945. In the early 20th century , some genius physicists have appeared in Germany and northern European countries . In this movie , Einstein, Heiserberg, Bohr, and Ratherford are seen. After bombing Hirosihma and Nagasaki , Oppenheimer talked with Einstein about how to prevent expansion of nuclear bombs. I remember that Schrodinger's equation in a chemical class as a freshman in a university. How difficult it was ! Einstein could not understand the dualism of an electrron as a particle and as a wave . The quantum mechanics has taught us accepting incomprehensible things. It's called Negative Capability. Quantum Entanglement , we don't understand but we should accept.
