Scientific funny jokes

German physicist Kirchhoff (1824- 1887) once pointed out in a lecture that the black line seen from the solar spectrum proves that there is gold on the sun. A banker who came to attend the class sneered at Kirchhoff and said, "What's the use of such gold if you can't get it from the sun!" Later, Kirchhoff won the gold medal for his discovery in spectral analysis. He showed the medal to the banker and said, "Look, I finally got gold from the sun."

German chemist robert bunsen (181-1899) was exposed to acids, bases and various chemicals for a long time, and his hands were covered with calluses. Once, when explaining the structure and performance of the bunsen burner alcohol lamp he invented, he put his finger on the flame of the alcohol lamp and casually introduced to people: "The place where I put my finger is about 300 degrees Fahrenheit."

The famous German physician John Xie Lun is not only superb in medical skills, but also praised for his heuristic teaching methods.

"Didn't you notice that I just dipped my middle finger into a small cup and licked my ring finger?"

On one occasion, the crowd surrounded the residence of Einstein (1879-1955), a scientist who immigrated from Germany to the United States, and asked him to explain his "theory of relativity" clearly in the simplest words. At that time, it was said that only a few outstanding scientists in the world could understand his works on relativity. Einstein walked out of the house and said to everyone, "For example, you and your closest relatives are sitting by the fire. An hour has passed, and you feel that it has only been five minutes! " On the other hand, you only sat by the hot stove for five minutes, but you seemed to sit for an hour. Well, this is the theory of relativity! "

Once, an American female reporter visited Einstein and asked, "In your opinion, what is the difference between time and eternity?" Einstein replied: "dear lady, if I have time to explain the difference between them, then when you understand, eternity will disappear!" " "
