Chapter 192 Living Legend (Thanks to Alliance Leader Beiyin Daze)

Physicists are the best at math.

Among mathematicians, physics is the best.

It's Edward Witten.

The most awesome thing is that this big guy 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 to further his studies.

In the end, he became the first and only legendary figure among physicists to win the Fields Medal.

As a physicist, how does it feel to receive the highest honor as a mathematician?

Probably a Meituan delivery person came to your house and found that your house didn't have an air conditioner on such a hot day, so he helped you make one with his bare hands. When he was about to leave, he found an unfinished doctoral thesis on your desk, so he asked you to deliver the food. He spent an afternoon writing it for you.

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

But Witten proved to the entire academic community that it is perfectly fine to use ingenious physical intuition to derive novel and profound mathematical theorems.

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

Witten won the Fields Medal because he connected the Jones polynomial and Chern-Simons theories. This research had a profound impact on low-dimensional topological structures and ultimately derived quantum theory. Invariant.

Kink theory was very popular in the 1980s, and mathematicians discovered many new kink invariants, the most famous of which was the Jones polynomial. At that time, many mathematicians were still busy figuring out what this new concept meant.

Witten stood up and told all mathematicians to look at the Wilson ring in the Siemens theory of Jones polynomials to connect the two.

Finally, some mathematicians discovered that no matter how many different 3-flow types there are, as long as they are multiplied by how many different gauge groups, as many kink invariants as 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 even more powerful is that he also analyzed a set of topological methods for shear flow patterns, which can intuitively and completely calculate the expectation value of the Wilson loop on any orientable 3-manifold. In this way, all the kinks and invariants of this family were wiped out in one fell swoop.

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 big guy is because he is the strongest person in string theory in the world. It can even be said that he has completed more than half of the "superstring theory" alone.

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

In fact, Wu Bin understands that if a physicist will study mathematics crazily, it is all due to the limitations of scientific level. Although string theory, the most promising theory to unify the basic particles and four types of interactions in nature, belongs to the category of physics. .

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

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

Because I really can’t understand it!

This made Wu Bin very dissatisfied. So far, this is the first copy where someone gave him a guide, but he couldn't even understand the guide... Oh no, it's a subject, so he vowed to pass string theory, no matter what In the end, this path is ultimately right or wrong!

However, 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 Edward Witten's M theory is very likely to be the ultimate theory of the universe.

In general, as long as string theory is proven correct, Edward Witten will be promoted 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 are you thinking of?"

"I just thought about why there are people with bugs like 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 was so complimentary."

"Don't be so modest with me. Next week I'm going to do physical research on strong field atoms and molecules. Come and help me. I'll give you a second job."

"Okay, no problem. Thank you, instructor, for taking care of me."

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

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

[Savior]: Can better combine physics and biology.

'High-end...'

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

After all, the first page is really a foundation for better mastering scientific research tools. The second page is directly about realizing 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 the least lit section.

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

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

‘Hey… Do you want to go to class?’

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

[Godfather of Information]: 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 talent that lights up the fastest on the human technological talent tree.

I often hear people say that the 21st century is an era of technological explosion. In fact, strictly speaking, this statement is wrong. To be precise, the 21st century is an era of information explosion, because on the human talent tree, it can be said that only the subject of information science is being used. Constantly lighting up, everything else is pretty much stagnant.

PS: Thank you to the leader Beiyin Daze for your domineering reward! There will be an extra update today, but it is definitely a bit late, so students don’t have to wait.
