He graduated from the Physics Department of China University of Science and Technology, and is now a professor in the Physics Department of China University of Science and Technology. Not long ago, he made amazing remarks in a science lecture at the National Science University. He said that 85% of physics and mathematics were not introduced to China, and many people didn't know that the triangle had more than 40,000 hearts.
Professor Cao said in class at that time: "I asked my classmates if they had studied the quadratic equation of one yuan, and many students said yes." So I tell you, about ten years ago, one day I suddenly understood one thing, that is, maybe 85% of the mathematics and physics in this world were not introduced to China.
When I was talking about this matter in a conference lecture of a Ministry, some of our leading comrades refuted me on the spot, saying that what Lao Cao said was always so extreme and not so serious. But in a couple of days, a scientific leader who has a particularly good relationship with me and I admire him called me and said, Lao Cao, I feel that what you said seems to be reasonable. "
"In order to prove that what I said makes sense, I actually asked them a question to let you feel it. You can also compare it. Did you ever have a triangle when you were in middle school? " Then the following students replied that they had learned the triangle center of gravity, and some said that they had learned the inner heart, the outer heart and the heart.
Then Professor Cao went on to say, "Then you probably don't know that the center of gravity is a physical concept. Inner heart, outer heart and center of gravity are geometric concepts, while center of gravity is physical concepts. So what should the mathematical concept be? It has its own story. You see, this is our textbook in China. It can't tell where this concept came from. This triangular plate has no center of gravity in outer space, but it has a center of mass, so it is the central problem. "
