Black technology starts from the steel suit

Chapter 206 Chapter 206 Untitled (Summary of Anti-theft)

The pick-up ceremony was not very grand, there were no welcome staff, no big fanfare and a line-up of convoys that looked imposing, except for several directors and a chairman, there were only two accompanying drivers .

According to Professor Boulter's introduction, both of them are Ph.Ds in electrochemistry from the Max Planck Society and part-time drivers. The reason is that I have admired his name for a long time: as one of the four major tiankengs of deepening materials, the awesome Wang Feng is almost the ceiling.

Although this kind of boss has not won the Nobel Prize in Chemistry, he is rich!

Worth trillions, do you think it's a joke?
However, if these people include two Nobel laureates and a Fields Medalist, then this airport pick-up, which is not grand in itself, becomes of great significance.However, as a pragmatist, Wang Feng actually doesn't care much about these red tapes.

As we all know, Wang Feng is a real person.

When he went to the capital to receive the award, he still wanted to try taking the subway alone after getting off the plane and sightseeing all the way, so as to experience the customs of the capital.

When he came to Berlin this time, Wang Feng no longer had that kind of naive idea. The world is very malicious. No matter at any time, you must protect your personal safety. You can just think about things like crowding the subway. He probably has no chance to experience it in his life.

"You are a genius. How did you come up with those formulas?" Professor Bolt couldn't help but ask as he got into the special car sent by Max Planck at the door and had just fastened his seat belt.Here is an old pedant, more interested in these things than in others.

Wang Feng said in a joking tone: "You may not believe it, but on the bed in my office, when I was studying human behavior, Mr. Schrödinger's manager gave me a lot of inspiration."

"wtf?"

Will laughed and said: "There is nothing implausible about this. The HF method and molecular dynamics simulations have borrowed inspiration from quantum mechanics to some extent."

Wang Feng: I think you may not understand.

Obviously not wanting to hear this guy bragging, Professor Bolt coughed lightly and continued to ask. "I've read your thesis, and although I don't understand some of the theories in it, I have many doubts about the parts I understand.

How do you exactly reduce the solution of the many-body ground state to the solution of the ground state density distribution?If it is through quantum mechanics, what is the difference between your theory and the first-principles calculation method in terms of results? "

The first-principles calculation method is the core method of modern computational chemistry, and the source of its core theory is quantum mechanics in quantum mechanics.This calculation method is advanced to a certain extent, but there are also big problems.

First of all, the number of variables has reached the astronomical number of 3N (N is the total number of particles), and secondly, its settlement results are often controversial.Because not only the number of variables is astonishingly large, in order to make the conclusion "beautiful", there are also too many empirical parameters added to it.

"Yes, but not quite"

Wang Feng smiled and continued, "I introduced the concept of partial functional density theory in the study room of the ground state density distribution. For example, the radius of the specified core region in the atom is taken as ra, which is called the cutoff radius. The pseudo wave function of is the same as the real valence electron wave function ψv, so that..."

"Let's discuss professional issues in a few days." Already feeling dizzy, President Strahman coughed dryly, changed the subject, looked at Wang Feng and continued to ask: "What are you doing these days?" How are you going to arrange it?"

Without a blackboard at hand, it is really difficult to continue the next part.Wang Feng made a helpless expression to Professor Bolt. After thinking for a moment, he continued: "Before the report begins, I would like to get familiar with the environment here. Is there any interesting place you can recommend to me?"

Upon hearing this topic, Professor Will suddenly became interested, and said vividly: "An interesting place? In the whole of Berlin, there is no place more interesting than the Max-Planck Laboratory. Shall I show you around?" Wang Feng's eyes As soon as it lit up, he immediately said, "Please take me to watch it."

Compared with landmarks such as the Brandenburg Gate and the Reichstag, the laboratory really interested him more.In particular, the laboratories of the Max Planck Society are well-known in the field of condensed matter physics.Wang Feng would not let go of such an opportunity to have a Nobel laureate act as a tour guide.

This is a temple for theorists to study. Although they are reluctant to admit it, compared with domestic colleges and universities, these places are undoubtedly less utilitarian and more tolerant and pure.

After half an hour's drive, we soon arrived at our destination.After getting off the car at the door of the Bernitz Hotel, Wang Feng took out the luggage from the trunk of the car.Just when he was about to say goodbye to several scholars, Wang Feng suddenly remembered something that had puzzled him for a long time.

"By the way, I've always wanted to ask a question."

Professor Will said kindly, "If I can answer it."

Wang Feng smiled: "This question may be a little unreasonable, but it's just out of my personal curiosity. Why did you publish such irrational news in the newspaper? Judging from your recent interactions, especially from your attitude See, this shouldn't be your style."

"Oh? Has something happened recently? Why don't I seem to understand what you said. "

“Have you seen the latest from The Sun and The Washington Post?”

"I don't read that kind of boring newspaper. Especially the "Sun" newspaper, we haven't subscribed for many years, and no one reads him."

"Is that so? Then you'd better go and have a look, because something big has happened."

"What!" Several old professors were shocked.

The predecessor of the Max Planck Society was the Royal Wilhelm Society established in 1911. The then Kaiser Wilhelm II believed that interest in science and technology could enhance national strength, so he established the society in his own name. The royal family funded scientific research to strengthen Germany. technical capabilities.

Judging from the height of the times, this decision was undoubtedly quite far-sighted at the time.Thanks to the support of national capital, a large number of outstanding scholars and scientific research projects continue to emerge, which has kept Germany's technology at the forefront of the world within 30 years.

After World War II, although the Royal William Society was disbanded, it was retained in the form of the Max Planck Society with the support of the United Kingdom.Of course, those stupid British didn't have any good intentions.Therefore, the two sides have never been able to deal with each other.

For scientists who pay more attention to facts, distorting and fabricating facts is intolerable for them.But the "Sun" has never been tired of it.

The impact of this historical legacy can still be clearly seen today.Although the position of the world's academic center has been moving across the ocean to the west since the Cold War, due to the hematopoietic ability of the Max Planck Society, Germany's research in engineering technology, condensed matter physics and other fields still maintains the world's leading level.

From this point of view, the Germans are undoubtedly much luckier than the French who lost their position as the center of mathematics in the world.

After staying in the hotel, Wang Feng took a rest for a day, and the next day, at the invitation of Professor Will, he went to the Max-Planck Laboratory in Berlin.Strictly speaking, this Max Planck laboratory is also one of the heritages of the Royal William Society, but after modernization, its original style is almost invisible here.

"...The laboratories of the Max Planck Society are distributed in various cities in Germany. This is just one of them, and it is probably the largest one. Many research institutes in the direction of physics and chemistry have a considerable number of research topics here. Here is Like a reactor, it ignites knowledge in various fields and releases its energy."

Wang Feng thought for a while and asked, "So the research here is carried out in units of research institutes?" Professor Will replied in a chatty tone: "That's not true. To be precise, most of the projects here are carried out by research groups. It is a unit, and there is a big difference between groups. For those who have not worked here, this may be difficult to understand, in short, you can understand that it is a research method that is completely different from that of American research institutions."

Walking on the tree-lined path leading to the Condensed Matter Physics Laboratory, Professor Will talked to Wang Feng about the composition of the Max Planck Society, and chatted with him about various anecdotes here.When passing by a flat circular building with a unique shape, Wang Feng cast a curious look there. "What's that over there?" Professor Will said with a smile, "That's the 'industry' of the Institute of Plasma Physics. You can guess what's in there. I bet you can't guess."

"Could it be a collider?" Wang Feng joked. "Haha, that's not true, this is a more sci-fi thing than a collider," Haha smiled, and Professor Will said in a joking tone, "You should have heard of it, the interesting thing about controllable nuclear fusion topic."

"Is that what you're talking about the so-called 50 years forever?" Wang Feng joked.

"Hey, friend, don't say that. Although we have encountered many difficulties, overall, we are still making steady progress."

How about cheating?

In this case, it's okay for you to talk nonsense with those amateurs who are in charge of funds.For an insider like yourself, you should stop talking nonsense, right?
In 1958, Egon Larsen wrote a book titled Atomic Energy: A Layman's Guide to the Nuclear Age.The book details the design of nuclear power plants and even futuristic atomic planes and nuclear-powered cars.The enthusiasm for nuclear energy that Larson and his contemporaries had so strongly displayed may have waned markedly since the 20s.

Still, at least one form of nuclear delivery is in operation, and uranium-powered submarines now routinely patrol our oceans.Today, some countries, notably France, are also using nuclear power to generate electricity.In fact, as of 2011, there were 442 operating nuclear power plants in the world, with another 65 under construction.

Despite its current size, the nuclear industry generally does not have a good reputation in news coverage.It is also understandable that the Fukushima nuclear accident in 2011, Chernobyl in 1986 and Three Mile Island in 1979 have all caused public and political doubts about the industry's safety and prospects.

Since these nuclear disasters, there has been great concern about possible nuclear leaks, reprocessing and long-term storage of nuclear waste.These concerns are not trivial.However, some members of the green movement are also touting nuclear power as the most desirable solution to producing more electricity in the face of climate change and dwindling fossil fuel supplies.On top of that, veteran environmentalist Stewart Brand is now promoting the use of nuclear power because it doesn't emit any greenhouse gases.

In the future, the dangers associated with nuclear power plants will also be significantly reduced.Today, the construction of all nuclear power plants is based on the nuclear fission process.However, the potential to switch to another process known as fusion exists.This just happens to drive the mechanism of claiming energy from the sun, which has the potential to be a safer source of nuclear energy for humanity in the future.

Given the levels and toxicity of radioactive waste produced by nuclear fission, nuclear physicists have been working for decades to build fusion power plants to reduce nuclear contamination.Since uranium reserves are unlikely to last until the end of the 21st century, another potential appeal of fusion power plants is reducing our reliance on relatively scarce nuclear fuel.

Currently, the most likely fuel for fusion power plants is two isotopes, or "heavy forms" of hydrogen, deuterium and tritium.In nuclear fission, the atoms of the fuel are split apart to release energy, while in nuclear fusion, two fuels are fused together at atomic units to release energy.So, although nuclear fusion releases atomic energy, it doesn't directly produce nuclear waste.In contrast, fusion reactions powered by deuterium and tritium produce helium and neutrons.

Therefore, nuclear fusion is safer than nuclear fission.Certain parts of a fusion reactor produce radioactivity during operation and must ultimately be disposed of safely.However, the long-term radiotoxicity of this indirect nuclear waste is much less than the by-products of current nuclear fission power plants.

The Sun gets its power from constant nuclear fusion reactions caused by the enormous gravitational pull.However, such conditions cannot be created on Earth.Therefore, to produce fusion in a reactor, fuel needs to be heated to extremely high temperatures.

In practice, this means heating them to temperatures in excess of 1 million degrees Celsius, or many times hotter than the sun.This extraordinarily hot plasma must remain dense enough and long enough to achieve "ignition" and self-sustaining nuclear fusion.You'd be surprised how difficult all of this is to achieve.

At least with the existing materials and engineering conditions, it is impossible to complete this kind of reagent engineering.But if he has no prospects, the committee will not continue to invest money in this project.

If they hadn't invested money in it, this project would never have been completed.So everyone compiled a beautiful lie about 50 years.

Over time, the nuclear fusion project has become a 50-year project, known as 50 years forever!
