Same as the search for Professor Artin's office.

Chen Zhou felt that there was no need for him to go through the freshman manual just now.

Along the way, MIT's enthusiastic classmates either wanted to show the way or take Chen Zhou to Professor Friedman's office.

Of course, after Chen Zhou got the accurate guidance, he politely refused.

But what he didn't expect was that Professor Friedman's fame seemed to be greater than that of other professors.

When Chen Zhou walked into the chassis of the physics department of the Massachusetts Institute of Technology.

He heard a lot of people talking about Professor Friedman.

It's just that the content of the talk is about him.

"I heard that Professor Friedman has accepted another graduate student?"

"It seems that yes, the man is said to be a math student at the same time. ”

"Don't look like it, it's just a math student. Remember last year's math conference?"

"You mean the Chinese student in the auditorium who directly proved Cramell's conjecture?"

"It's him, Professor Friedman's new student, my Chinese student. ”

"Gan, let me just say, why did Professor Friedman suddenly bring up the graduate students again, it turned out to be this great god......"

He later seemed to prove the Jebov conjecture, so that's nothing. Anyway, mathematics is in the service of physics, and if students from other departments were to come under Professor Friedman, they would not dare to come under Professor Friedman. ”

"Yes, it's barely acceptable. Under the throne of physics, probably only mathematics can make us agree with it a little......"

Hearing this, Chen Zhou couldn't help but have question marks in his mind.

What does that mean?

According to them, or is it because I studied mathematics that I am qualified to study physics?

Is this the chain of disciplinary contempt?

Could it be that physics is at the top of the chain of disciplinary contempt?

But shouldn't it be mathematics that stands at the top?

Chen Zhou knows that in universities, especially in such awesome universities, there is such a thing as a chain of discipline contempt.

However, I didn't expect to be bumped into by myself.

Shaking his head slightly, Chen Zhou shook the question in his mind out of his head.

All he feared now was his mentor, Professor Friedman, who was also a disdainful chain of disdain.

Coming to the door of Professor Friedman's office, Chen Zhou glanced at his watch, and the time was just right, not exceeding the agreed time.

Immediately, he knocked softly on the office door.

With a "please come in", Chen Zhou pushed open the door and walked in.

The purpose is that piles of thick papers are not neatly stacked together.

Behind the papers, there were two fairly young faces.

They were looking up at Chen Zhou.

Chen Zhou greeted politely: "Hello two senior brothers, is Professor Friedman here?"

Hearing Chen Zhou's voice, the two realized the identity of the comer.

One of the men, who was slightly taller, got up with a smile and said to Chen Zhou, "Professor Friedman is inside." ”

Chen Zhou subconsciously looked inside, but didn't see anyone.

The view was blocked by the piles of paper.

Noticing Chen Zhou's movements, the man explained with a little embarrassment: "The professor likes to keep all the materials, so it's like this." ”

Chen Zhou nodded, indicating understanding.

Although he didn't expect such a scene, he was not surprised.

Because when he studied mathematical conjectures on his own, scratch paper was also piled up all over the floor.

The man said, "Introduce yourself first." My name is Ennis McThesson, and I am a PhD student under Professor Friedman. ”

As he spoke, McIson pointed to another person and said, "His name is Gleb Coyle, and he is also a doctoral student under Professor Friedman's supervision." However, one year lower than me. ”

Coyle also got up at this time, and said to Chen Zhou with a smile: "Welcome, our little junior brother, Professor Friedman is waiting for you." ”

When Chen Zhou heard this, he also said, "Thank you, it's a pleasure to meet you, Senior Brother McIson and Senior Brother Coyle. ”

McIson patted Chen Zhou's shoulder: "You're welcome. ”

After speaking, he made way for Chen Zhou.

Chen Zhou glanced at him, raised his feet and walked inside.

In the deepest part of the office, there is a desk.

On the desk, there is only paper and pen.

Modern office supplies, not a single one.

Behind the desk was an old man with gray hair.

The old man was intently holding a pen and doing calculations on scratch paper.

The old man's eyes only had the paper and pen in front of him, so much so that Chen Zhou walked to his side and didn't notice it.

Chen Zhou looked at the old man's serious appearance, and a trace of respect rose in his heart.

In any case, whether it is mathematics or physics, it is a bowl of young rice.

When he was young, he had a quick mind and a lot of energy.

But as you get older, your thinking slows down and your energy can't keep up.

It is really a very admirable thing that an old man like Professor Friedman, who is almost 90 years old, can concentrate so much on research.

Chen Zhou probably understood why the conversation with McIson and Coyle just now didn't disturb Professor Friedman.

Chen Zhou glanced at what Professor Friedman had written, then quietly stepped aside and waited silently.

He wasn't going to interrupt Friedman's train of thought.

Perhaps, it was a rare immersion time.

Chen Zhou himself also hates others interrupting his train of thought, so he understands very well that this sense of immersion is rare.

Chen Zhou's reasons for choosing Professor Friedman are different from those for choosing Professor Artin.

Professor Friedman is a great expert in the field of nuclear physics.

He studied under the father of atomic energy, Enrique Fermi.

Fermi is known as the Great Physicist.

Fermions, the No. 100 chemical element Fermium, the Fermi Lab in the United States, and the Fermi Institute at the University of Chicago are all named in his honor.

This is a physicist who has achieved first-rate achievements in both theory and experiment.

Even among the star-studded modern physicists, there are only a handful.

And as a student of such a big man, Professor Friedman is naturally very good.

In 1990, he was awarded the Nobel Prize in Physics for his work on the deep inelastic scattering of nucleons.

And this research started with the Linear Accelerator Center at Stanford University, also known as SLAC.

Subsequently, in 1967, a large electron linear accelerator was built and reached design energy.

Friedman began a series of electron-proton scattering experiments.

These include electron-proton elastic scattering experiments, positron-proton elastic scattering experiments, and electron-proton inelastic scattering experiments.

Of course, the results of these experiments only confirm the existing conclusions.

But when the energy of the incident electrons increases further, it enters a deep inelastic scattering region that has never been explored before.

At first, after getting the experimental results, Friedman and his collaborators thought that the experimental results were incorrect, or that there was an error in the interpretation, or that there was a systematic error, or something like that.

But with a large number of experimental results, as well as the calibration between the experiments.

They found that electrons go deep into the interior of protons with great energy.

Instead of a "soft" proton target, it encounters a punctate "hard" nucleus similar to an electron.

At the time, experimental physicists could not understand this, let alone explain it.

This was followed by a great deal of work, even using abstract mathematical methods such as flow algebra.

Finally, from the depth inelastic scattering experiment and scale independence, important evidence of some sub-models is found.

It soon became clear that partials and quarks turned out to be the same thing.

And Friedman's research in this field has never stopped.

Moreover, before the Super Collider was launched, he was responsible for designing the detectors that would accompany it.

In addition to this, Friedman makes two very simple assumptions about the universe.

Although Friedman found only one model, there were actually three models that met his two basic assumptions.

The first of these models was found by Friedman himself.

It can be said that this is a physicist who, like his teacher Fermi, has made achievements in theory and experiment.
