Recently, when Zhang Chaoyang lectured on physical questions, Zhang Chaoyang proposed a general question of generally calculating a uniform exercise charge, so that netizens answered an iPhone14 as the answer.

The question was solved by a girl from the Physics major from Nanjing Normal University. The classmate said that she was preparing for the postgraduate entrance examination recently and would take the time to look at the physics class. I felt very interesting to try to answer.

On the evening of September 15, related topics rushed to Weibo hot search.

Zhang Chaoyang answered only one person in the physical question test:

Reward a iPhone 14

Recently, in the live physical class, Sohu Zhang Chaoyang proposed a topic question that generally calculated a uniform exercise charge to test netizens, and promised that if netizens could answer the right, I would send an iPhone 14 as a prize.

In the end, a female college student from Jiangsu gave the correct answer and said that she was in the postgraduate entrance examination, so she would study physics courses and found the answer through reference textbooks.

In an interview, the classmate said that he prefers physics and felt very interesting. When he first came into contact with this topic, he thought it was very simple. As long as you wrote an electromagnetic field, it was really difficult to find the question during the subsequent answer.

Partial disintegration step

However, I was more stubborn, and finally changed my thinking through reference textbooks and made a picture.

The classmate also said that he was preparing for the postgraduate entrance examination recently. He only went to see the live broadcast of (Zhang Chaoyang) while resting, and said that he was very good. For the material reward herself, she responded very humorously that through this, she said that through this kind of this kind of Forms allow more people to understand the existence of the classroom, and to make many people realize that "there is such useful reading."

According to@Physics class, in the physics class of Zhang Chaoyang on September 11, Teacher Zhang explained the electromagnetic field and relativity effects of the exercise charge, and proposed a problem that requires calculation of the potential and magnetic direction of the entire space in the entire space. Essence This question was solved by a girl from the Physics major from Nanjing Normal University. Her problem solving idea was to use an explicit calculation to calculate the points of delayed momentum, and eventually successfully gave a complete expression. Congratulations to the classmate for getting an iPhone 14.

Netizens have said: "I should also be able to return to high school" "This physical question seems to be reading English" "Can you start from the foundation" ...

Physics class has been broadcast live for more than 80 issues

Also popular science iPhone 14 color scheme

As of now, "The Physics Course of Zhang Chaoyang" has been broadcast live for more than 80 issues. The content is rich and covered. The theoretical formulas have been integrated from shallow to deep and complicated. Since the first section of physical live lessons was started in November last year, he first started with classic physics, and popularized the law of Newton's exercise. Then he started from the classic physics "two black clouds" and transitioned to modern physics. He discussed the black body radiation In the theory, the Wein formula, Planck formula and other knowledge.

Since then, gradually entered the field of quantum mechanics, from the theoretical contents of the basic Xue Dingli equation, to the hydrogen atomic wave function, to the temperature staircase of the heat to the heat, and explained the law of thermodynamic. Then I returned to the classic physics, derived the operating trajectory of the spacecraft, estimated the structure and nature of the sun and the rotation speed of neutron stars, and then explained the progress of the gyro, and calculated the tidal height of the moon. And now I have begun to explain some mathematical tools and prepare to enter the general theory of relativity.

In addition, Zhang Chaoyang recently popularized the purple color of the iPhone 14 series in physics classes, indicating that there is no such color in the spectrum.

According to Zhang Chaoyang, there is no purple in the solar spectrum. When the human eye sees purple, it will be superimposed to the spectrum, so the purple of the iPhone 14 series is relatively rare and impressive. In addition, Zhang Chaoyang also said that the iPhone 14 series has many powerful functions, and the design is also very good.

The live broadcast style of "Zhang Chaoyang's Physics Course" is unique: Pay attention to derivation. Through step -by -step mathematical calculations, it derives the relevant physical formulas and disassembles each formula from beginning to end.

In addition to the "Physics Class of Zhang Chaoyang", in terms of live broadcast, Sohu Video is continuously creating a live broadcast platform, inviting head broadcasts in various scientific fields to settle in for live broadcast of science popularization knowledge. Including Qian Hang, an expert in the China Institute of Launch Rocket Technology, explained the history of the development of aerospace industry; Dr. Chen Zheng, Teacher Chen Zheng of Beijing Jiaotong University School of Science and Technology, to start a class- "Strange Science Experiment"; The founder Tian Yan explained the close connection between genomics and life; Liu Boyang, a doctor of celestial physics, "how to produce a full -eclipse" and so on. In the future, there will be more knowledge to broadcast the owner to the Sohu video and interact with science together.

Netizen: The mental internal consumption has been cured

Recently, the "Physics Course of Zhang Chaoyang", which is more than half a year in Sohu video, was broadcast live in Douyin for the first time, focusing on electromagnetics, with a length of more than two hours, attracting more than 50 million people to watch online.

Seeing Zhang Chaoyang as a "Internet leader" for many years, many people don't know that he actually graduated from the Department of Physics of Tsinghua University and received a PhD in Massachusetts Institute of Technology. Zhang Chaoyang talked about physics, in fact, it was a professional counterpart and returned to the original intention.

In this lesson in Douyin, he fully implemented his opinion: "Physics is calculated", after introducing the process and significance of human discovery and application of ground magnetic waves, he began to derive formulas on the blackboard.Speaking of professional nouns such as vector micro -integrals, scattered theorem, Stocks theorem, Kuron theorem, Gaussian theorem, etc., they quickly wrote six blackboards to derive the famous Maxwell equations.Many netizens said that watching this live broadcast is the moment when the formula derives success. It feels refreshing, the sun is bright, and the mental internal consumption is cured.Perhaps this is the magic of knowledge, this is the magic of science.
