Hearing his old friend's words, Chen Dezhi had a smile on his face, after a week of getting along, he was more satisfied with Shang Yiyun, so today's academic forum, he will bring Shang Yiyun to broaden his horizons.

"Yes, although Yi Yun is a first-year student, he is no worse than some graduate students now, and Yi Yun still entered Kyoto University as a champion in liberal arts, if it wasn't for skipping my class, I wouldn't have found such a good seedling. ”

After speaking, Chen Dezhi had a smile on his face, after this period of inspection, he was now really satisfied with Shang Yiyun.

The two elders were talking, Shang Yiyun could only listen, and he couldn't interject at all, when he heard his mentor's words, he was very happy in his heart, which meant that the mentor had completely accepted him.

It was only the first time they met before, although Chen Dezhi felt that he was talented, but after all, he didn't know much about Shang Yiyun, so he spent a week to inspect him, and every time he went to the other party's office, the other party would ask some questions for him to answer.

Some of these questions may not be answered even if they are master's students, but he did not disappoint the other party, and answered them all, although some of the answers were slightly flawed, but Chen Dezhi was already very satisfied, after all, Shang Yiyun was still a freshman student, and there was still a lot of time in the future, didn't he.

Chen Dezhi and the old man showed their faces for a while, time passed minute by minute, and soon it was two o'clock, the academic forum officially began, and Shang Yiyun also cheered up, although the next content may not be understood, but if you can understand some of it, even if you have a harvest.

The first step is the opening ceremony, after the host said a few words, let a bespectacled, chubby old professor give an opening speech, this old professor is the dean of the School of Physics of Kyoto University, after the opening speech, the next is an important person to make the main speech, this important person is Professor Zhou Xunda of the School of Physics, but also an academician of the Chinese Academy of Sciences.

His main research interests are electromagnetism and motion mechanics, and he has made great contributions to the scientific research of China, and was awarded the honor of academician of the Chinese Academy of Sciences in 2015.

"Ladies and gentlemen, as we all know, the founder of electromagnetism was the great English physicist Maxwell in the 19th century, who was also the founder of classical electrodynamics and one of the founders of statistical physics, Maxwell integrated and developed Faraday's ideas on electromagnetic interactions, and published the famous "Theory of Electromagnetic Field Dynamics" in 1865 summarized all electromagnetic phenomena into a set of partial differential equations, which is Maxwell's equations, which are the fundamental equations of electromagnetism, predicted the existence of electromagnetic waves, and confirmed that light is also an electromagnetic wave, thus creating classical electrodynamics. Maxwell also made important contributions to the theory of gas motion, optics, thermodynamics, and elasticity. ”

"Electromagnetism, or electrodynamics or classical electrodynamics, is called classical because it does not include the content of modern quantum electrodynamics. ”

"Today, more than 100 years later, electromagnetism in China has developed......"

At the beginning, Shang Yiyun could still understand the basic common sense, but the back became more and more esoteric, and he could only listen to Professor Zhou Xunda's speech in a daze, and ten minutes later, the other party finished speaking, and Shang Yiyun reacted.

Everyone present, except for Shang Yiyun and those reporters, was not a big man in the academic world, even if the main research direction was not in the field of electromagnetism, he was involved in a lot, so his face was very flat.

I accidentally caught a glimpse of those campus reporters, the photojournalists were better, they only needed to take photos, but the text reporters were miserable, with a confused expression, and they didn't understand anything.

For this situation, it is also expected by Shang Yiyun, this kind of academic forum can only be understood by those doctors who have a deep research in electromagnetism.

The next is the most important part of the academic forum, since it is a forum, the most important thing is naturally the speech of the author of the paper, and the people present are either academicians of the Chinese Academy of Sciences, or Changjiang scholars, or scholars of the Thousand Talents Program, all of whom are bigwigs in the academic community.

Most of these academic bigwigs are from Kyoto University and Huaqing University, two of the top universities in China, are in Kyoto, and many times, they will choose to cooperate.

The first one on the field was a professor from the School of Physics of Kyoto University, who copied the ppt file to the computer, opened it, and began to tell, at this time, Shang Yiyun also began to listen carefully, the academic speech of this level of scholars, if it can be understood, the harvest is absolutely great.

"The electromagnetic phenomenon that is ubiquitous in nature has been widely used in various fields such as production and life, engineering technology, aerospace, and military after being discovered and studied. Among them, in the space levitation technology related to aerospace for the purpose of simulating the microgravity environment, the electromagnetic levitation technology has become mature. ”

"Electromagnetic levitation technology is referred to as EML technology. Its main principle is to use the eddy currents generated by high-frequency electromagnetic fields on the surface of metals to achieve the suspension of metal balls. When a metal sample is placed on a coil with a high-frequency current, the high-frequency electromagnetic field will produce a high-frequency eddy current on the surface of the metal material, which interacts with the external magnetic field and subjectes the metal sample to a Logoz force. Under the appropriate spatial configuration, the direction of the Lopinz force can be made to be opposite to the direction of gravity, and the electromagnetic levitation can be achieved by changing the power of the high-frequency source to make the electromagnetic force equal to the gravitational force. ”

The subject of the professor's thesis is the application of electromagnetism, now, the maglev train has been put into use, on May 6, 2016, that is, last year, China's first with completely independent intellectual property rights of the low-speed maglev commercial operation demonstration line - Huxiang maglev express line opened for trial operation, China in the application of electromagnetism, gradually improved.

The principle of this technology, although Shang Yiyun does not understand much, but in terms of application, he still understands some, maglev trains, this kind of thing, I have heard of a few years ago, if it can really be applied on a large scale, people's travel is definitely much more convenient.

After more than ten minutes, the professor finished speaking, and the people in the room, except for Shang Yiyun and a few reporters, were all in deep thought, these people were thinking about the knowledge in the paper, although some people's research direction is electromagnetism, but there are also some branches of electromagnetism, participating in this academic forum, there is also a reflection with their own research.

The next time became a stage for these experts and scholars, who told their papers one after another.

Shang Yiyun made soy sauce throughout the whole process, and he couldn't understand it in many places, so he could only stand there, showing a confused expression.
