The anti-terrorism situation in New York is really serious, and the moment Juchen proposed a solution to it, the FBI told him to come to New York. After a transfer in San Francisco, I flew for more than ten hours, and when I arrived in New York, I just got off the plane, and there were already a bunch of FBI agents waiting below, and I immediately introduced three MIT students, it is said that no one in the FBI understood the reverse engineering principle that Ju Chen said, the person in charge patted his head, and immediately went to MIT to find three students with excellent character and learning to listen to the class, and the FBI will not directly let a foreigner be responsible for cracking the secret tube this time, so Ju Chen must first teach these three MIT undergraduates, and then act indirectly.

It's been a hard time these days, because Juchen's English is not good, let alone being a teacher for three college students. The process of preparing how to explain is more painful than preparing for a lesson.

Juchen still learned through the mouths of the students that the bitcoin account of a certain criminal group actually contained 8-digit value of bitcoin, and it was related to homeland security.

When the three students have mastered Ju Chen's strange skills, Ju Chen feels that he is almost ready to be a professor taught in English.

The time was almost up, and he had to leave for Nashville, and the F.B.I. did save Vanderbilt University money on airfare.

This is Juchen's first time traveling abroad, and he doesn't know what to see, he doesn't like to enjoy the scenery, because he pursues a sense of control, he may not have been in any park for ten years, and when he goes to other people's countries, he is even less interested in going to public places, so whether he is in New York or Nashville, he has a very boring trip - just stay in the hotel to "prepare for class".

Vanderbilt University is Nashville's largest employer, with 20,000+ employees, far more than city, state, and federal employees on the ground. Around Fan University, there are the best local hospitals, this school is also known as the "Harvard of the South", and its comprehensive ranking is in the top 20 in the United States, however, the physics department is not good, and it should be in the top 50 in the United States.

At such a level, it still attracted many people to listen to the speech, and it was hard to get a vote, which shows that Ju Chen's reputation as a cutting-edge scientist is still very loud.

I heard that it was very popular, Juchen was happy, and finally found the most suitable way to travel for himself - bragging in front of his peers or half of his peers.

This time the boasting is really not small, it is a further deepening of the three-dimensional world view, this time it is an explanation of the three-dimensional space from the direction of topology, to be honest, it is as shocking as Fermat's theorem.

There is a theory in topology, called the "kink theory", which studies curves in three-dimensional space. Why does it have to be three-dimensional space? No one seems to have thought about it the other way around, only the positive direction of the explanation, because two-dimensional space does not have enough dimensions to make a curve entangle itself and knot, but what about four-dimensional space? This is the most wonderful thing, when the dimension becomes four-dimensional, a strange phenomenon occurs, and no matter what kind of knots can be easily untied into a curve without knots.

On the other hand, isn't this a great way to reflect the advantages of a three-dimensional universe? Complex kinks can be formed, and only in such a universe can complex matter exist stably. It was very difficult to imagine how the four-dimensional space affected the kinks, so Ju Chen kept thinking about how to cover it up, and repeatedly experimented with a rubber band, and finally completed his little magic.

On the day of his speech, after boasting in pale language, he began to simulate the result of kinks in four-dimensional space with rubber bands.

Driven by the close-up shots he specially ordered, the audience stared at this creatively historic moment, which may be the first time to demonstrate the legend of the fourth dimension in three-dimensional space, and through the special opening and closing of the rubber band, many viewers actually understood and applauded this ingenious demonstration.

When Steve Jobs released the product on stage, many people in the audience applauded, but too many people knew how to do it, and when a mathematician used magic-like means to explain information that was almost impossible to convey, even scientists and engineers couldn't help but applaud loudly, which was much more difficult than any rock star or technology expert.

The social network of the academic circle was instantly swiped by Ju Chen's video, and later, whether you can read it or not, you must forward it, otherwise you must prove that your IQ is not good.

used to be famous in China, but now it has finally become famous internationally, and Fan Da is afraid that he will not be able to invite science Internet celebrities with a small broken assistant professor.

People are afraid of being famous, pigs are afraid of being strong, in just three days, Juchen is still digesting the pleasure of being an international science Internet celebrity, and an unfortunate news came, he hid a secret cylinder for the FBI reverse engineering, and was discovered by media reporters, and the matter was poked out.

For the time being, others think that Juchen is helping, and they haven't thought about it yet, Juchen is the identity of the inventor behind the secret tube has not been exposed, but I'm afraid it won't take long, after all, the patent belongs to him, and there will be good people to check the relevant patents soon.

Then the secret tube was sold, and although there was a possibility of being cracked, curious consumers were still willing to buy it back and study it, after all, the gadget was very cheap.

Due to the reason that Juchen does not know, it is really difficult to obtain the internal password through ultrasonic piercing, and several professional security laboratories have made failed attempts, which makes the secret cylinder more famous, and now, except for the reverse engineering method "developed" by Juchen has been mastered by the FBI, no one can crack it.

Juchen is running out of money in Nashville, but fortunately, a small business comes to the door at this time, and a local media wants to interview, and he can give 10,000 US dollars in appearance fees, which should be able to cope with it for a while.

It was embarrassing to be interviewed this time, and he didn't understand several questions from the host, so he had to ask the host to slow down and cooperate with gestures to understand, because the questions asked were too ...... low, it doesn't match the identity of a rising star of science at all, if it weren't for the sake of 10,000 US dollars, Juchen would have flashed a long time ago.

The 10,000 yuan has not yet been heated, and the incident of his almost endorsement for the tobacco company has come to light, and the American media still wants to dig up this news very much, and report it as super negative. As a result, the news that a scientist asked for money and shamelessness suddenly flooded the mainstream media.

Internet celebrities, negative, some people support it, some people spurn it, and the news bombards it in turns, Juchen has become a super controversial scientist, and universities that lack a little courage dare not hire him.

Because helping the FBI crack the secret tube may bring a sense of security to New York, he seems to have a good reputation in New York, so much so that the physics department of Columbia University sent him an invitation, and finally a heavyweight university was willing to hire him.

Columbia's physics department is probably ranked around tenth, which is already very powerful, but the only pity is that this is an associate professor position, not a tenured teaching position.

Alas, it's good to be an Internet celebrity, Juchen never thought of being a professor at a famous school like Columbia University.

Juchen doesn't like New York, or the United States, he wants to go home, but he has to work to be rich, so he has to make compromises, or gilded, so that when he goes home, he can be a full professor.

Surprisingly, Pei Li and Ivanka both liked New York very much, and they both came to see him happily, and they were coming almost at the same time, what could Juchen say?
