5.1930, the British physicist Paul Adrien Maurice Dirac, 1902 ~ 1984) when using mathematical methods to describe the laws of electronic motion, it is found that the electronic charge can be a negative charge or a positive charge. Dirac's conjecture is that there may be an "abnormal" positively charged electron in nature. 6. The Austrian theoretical physicist Erwin Schrodinger (1887-1961) developed quantum mechanics in the late 1920s s along with Einstein, boder, boun, and hossenber. He was a
