This book can make readers think more, expand the knowledge boundary and enter the state of deep learning. As a supplementary reading material for traditional physics textbooks, it is worth reading.

"Zhang Chaoyang's Physics Course" is a brain-burning network course that is popular all over the network, and it has won super popularity with high-density knowledge output. Under the background that Sohu video builds a knowledge live broadcast platform, Zhang Chaoyang's physics class is broadcast on 20211.5, and every Friday and Sunday 12, Zhang Chaoyang gives live lectures on physics in Sohu video. At present, more than 100 classes have been taught, and this book is the content of the first 50 classes.

In this book, Zhang Chaoyang starts from natural phenomena, leads to basic physical concepts, deduces basic theories, studies the roots behind phenomena, and obtains essential understanding, covering mechanics, thermodynamics, electromagnetism, quantum mechanics and so on. In this book, mathematical deduction is more used to show the inseparability of physics and mathematics, which can also help readers improve their mathematical level.

Zhang Chaoyang, founder, chairman and CEO of Sohu. 1986 graduated from the physics department of Tsinghua University, and in the same year, he was awarded a CUSPEA scholarship to study in the United States. /kloc-0 received his Ph.D. from Massachusetts Institute of Technology (MIT) at the end of 1993, and continued his postdoctoral research at MIT. 1996 returned to China with venture capital to set up Aite New Company, and launched "Sohu" product in 1998, and renamed the company as Sohu Company.
