2 In the field of observation, opportunities only favor those who are prepared.
Ampere is actually tested before ampere discovered that electric energy produces magnetism, but Ampere only added several coils on the basis of predecessors, and Newton's apple fell to the ground.
3 The biggest difficulty in discovery is to get rid of some traditional concepts.
Planck: put forward energy quantization
. Although Rayleigh, Jenkins (1877-1946) and Wayne (1864-1928) put forward two formulas respectively in an attempt to find out the law of blackbody radiation, compared with experiments, Rayleigh-Jenkins formula only fits in the low frequency range, while Wayne formula only fits in the high frequency range. Planck began to study thermal radiation systematically in 1896. After several years of hard work, he finally derived a formula that was consistent with the experiment. In late October 19, he published a three-page paper in the Bulletin of the German Physical Society, entitled "On the Perfection of Wien Spectral Equation", and put forward the blackbody radiation formula for the first time. On December 14th, at the regular meeting of the German Physical Society, Planck gave a report on Energy Distribution in Normal Spectrum. In this report, he excitedly expounded his most amazing discovery. He said that in order to get the correct radiation formula in theory, it must be assumed that the energy radiated (or absorbed) by matter is not continuous, but one by one, and can only be an integer multiple of a certain minimum value. This minimum value is called the energy quantum, and the radiation frequency is the minimum value of energy of ν ε=hν. Among them, H, Planck called it the fundamental action quantum at that time, and now it is called Planck constant. Planck's constant is the most important physical constant in modern physics, which indicates that physics has changed from a "classical larva" to a "modern butterfly".
