My profession makes me a witness of cutting-edge technology. Scientific things require repeatability, also known as reproducibility, while my hobby, metaphysics, is illusory and seemingly non-existent and completely unreproducible. These are two completely different things. Extreme. But I have come into contact with many industries and people. During this period, some mysterious and inexplicable things happened. I feel that these two extremes can be contradictory and unified. I just happened to be busy. I recalled all the previous things and sorted out this record. Share it with everyone.
