What kind of person is Planck?
Planck is modest and rigorous. At the commemorative meeting of the German Physical Society to celebrate his 60th birthday in April, 19 18, Planck replied: "Imagine a miner who tries his best to explore precious minerals. Once, he discovered a natural gold vein, and after further research, he found that it was priceless, countless times higher than previously thought. If he didn't find this treasure himself, there is no doubt that his colleagues will find it quickly and luckily. " This is of course Planck's modesty. What Lorenz said when commenting on Planck's bold energy quantum hypothesis revealed the essence of the problem. He said: "We can't forget that only those who work hard and think deeply can get the good luck of this inspiration."
