Xueba's Sea of ​​Stars

Chapter 192 A Living Legend (thanks to the lord Beiyin Daze)

Physicists are the best in mathematics.

Mathematicians are the best in physics.

It was Edward Witten.

The most amazing thing is that this boss studied history and language as an undergraduate. After working for a few years after graduation, he suddenly found physics very interesting, so he went back for further studies.

In the end, he became the first and only legend among physicists to win the Fields General.

As a physicist, what is it like to receive the highest honor of mathematicians?
Probably a Meituan deliveryman came to your house and found that there was no air conditioner in your house on such a hot day, so he made one for you with his bare hands.When he was about to leave, he found that there was an unfinished doctoral thesis on your desk, so he asked you to deliver food, and he spent an afternoon writing it for you.

We must know that pure numbers have always stood at the top of the discipline discrimination chain. According to the words of mathematician Green, if science is to climb a peak, then for thousands of years, mathematicians have climbed far ahead. Kicking down a stone is enough to provide inspiration and theoretical support for the physicists below.

However, Witten proved to the entire academic community that it is completely okay to use ingenious physical intuition to derive novel and profound mathematical theorems.

Of course... only his inhuman intuition can do it.

Witten won the Fields Medal because he connected the Jones polynomial (Jones polynomial) and Chern-Simons (Simmons theory) theories. invariant.

Kink theory was very popular in the 80s. Mathematicians discovered many new kink invariants, the most famous of which was the Jones polynomial. At that time, many mathematicians were still busy clarifying what this new concept meant.

Witten stood up and told all mathematicians to connect the two by looking at the Wilson ring in the Jones polynomial Simmons theory.

Finally, mathematicians found that no matter how many different 3-manifolds there are, as long as they are multiplied by different gauge groups, how many kink invariants similar to Jones polynomial can be constructed.

So the Jones polynomial is just one of the invariants belonging to this family, and there are infinitely many more like this.What's more, he also analyzed a set of shear flow topology methods, which can intuitively and completely calculate the expectation value of Wilson loop on any orientable 3-manifold.Thus, all the kink invariants of this family are wiped out at once.

This process is like a group of mathematicians who were dancing in front of a newly discovered treasure cave. When they opened the door, they found that Witten was already sitting inside, and said to them calmly: "Stop looking at the tip of the iceberg." Tell them how big the treasure is, and then take all the treasures away."

The reason why Wu Bin is so familiar with this boss is because he is the strongest person in string theory in the world, and it can even be said that he has completed more than half of "superstring theory" by himself.

The purpose of his study of mathematics is actually similar to that of Newton's study of calculus, which is to better study physics, including the reason why he won the Fields Medal is also to study quantum.

In fact, Wu Bin understands that a physicist will study mathematics crazily because of the limitation of scientific level. The most promising theory, such as string theory, which unifies the fundamental particles in nature and the four kinds of interactions, although it belongs to the category of physics .

But it looks more like a mathematical game, because it is impossible to test string theory with scientific methods at this stage.

And his various books and academic papers can also be said to be the biggest reason for Wu Bin's great interest in string theory.

Because I can't understand it!
This made Wu Bin very dissatisfied. So far, this is the first dungeon where someone gave the guide but he can't even understand the guide... Oh no, subject, so he vowed to pass the string theory, no matter what In the end this path is ultimately right or wrong!
However, at present, it seems that various physics experts are still very optimistic about string theory. For example, Hawking proposed in his book "The Grand Design" that he believes that Edward Witten's M theory is very likely to be the ultimate theory of the universe.

In general, as long as the string theory is proved to be correct, then Edward Witten will be pushed to the altar of physics like Newton and Einstein.

Seeing Wu Bin suddenly in a daze, Feng Jinhui patted him and said, "What good thing do you want?"

"Just thinking about why there are people with such a bug as Witten."

"I think you're quite buggy too. You're the only one I've ever seen who's such a monster in my freshman year."

"The instructor is absurd."

"Don't be falsely modest with me, next week I will do physics research on strong field atoms and molecules, please help me, I will give you a second work."

"Okay, no problem, thank you tutor for taking care of me."

Feng Jinhui shook his head with a smile, and continued to do his own experiments.

Wu Bin continued to open the talent page and read it.

[Savior]: It can better combine physics and biology.

'High end...'

After reading this, Wu Bin almost understood that it seems that the B box on the second page of talent is going to blow up the first page.

After all, the first page is really laying the foundation, in order to better master scientific research tools.And the second page is directly rushing to realize the theory.

This [Savior's] talent is obviously a BUFF to biophysics, an interdisciplinary subject that combines physics and biology.

In fact, if the entire human technology is a talent tree, then biophysics should be regarded as the least lit section.

Its research purpose is to study the physical characteristics of organisms, covering all levels of biological organization from the molecular scale to the entire organism and ecosystem.

The scope of research is quite broad, including physiology, biochemistry, nanotechnology, bioengineering, agricultural physics, and cell biology.

"Hiss...do you want to go to class?"

Wu Bin thought for a while, felt there was no rush, and looked at the next talent.

[Information Godfather]: It can better combine electronics, modern physics, optoelectronics, quantum electronics and superconducting electronics.

'Oh my god, this is physical electronics. '

Physical electronics, which is also an interdisciplinary science, mainly conducts basic and applied research in the fields of electronic engineering and information science and technology.

Contrary to biology, it is the fastest lit talent on the human technology talent tree.

I often hear people say that the 21st century is an era of technological explosion. In fact, strictly speaking, this sentence is wrong. To be precise, the 21st century is an era of information explosion. Constantly lit, everything else is pretty much at a standstill.

PS: Thank you leader Beiyin Daze for your domineering reward!There is an update today, but the time must be a bit late, students don't have to wait.
