Twenty years later, the super material graphene was made in a very simple way, and now, the concept of graphene has not yet appeared, and the phenomenon of quantum entanglement was confirmed by scientists last year, and thirty years later, China has launched the Micius satellite into space, as well as quantum computers and genetic modification technology, thirty years later, not only has it been formed in theory, but also can be operated in practice, and now, many of them have not even appeared in related theories。

In Liu Lang's eyes, the next 30 years will be the fastest developing 30 years in human history, which is not only at the technical level, but also the development of theories.

Of course, it is useless to know these theories, you still have to have solid papers to demonstrate, although Liu Lang knows a lot of papers that exceed this era, but I don't know how these papers are written, although many theories are not mastered, but after twenty or thirty years, the shape of many machinery is still remembered, there are some large mechanical equipment Liu Lang can not know the internal structure, but some small equipment can still be recalled with his super memory, for example, when Liu Lang watched the TV news yesterday, he saw the picture of a fire truck fighting a fire in front of a high-rise building, and the ladder stretched out by the fire truck only reached a height of six floors, which was about sixteen or seven meters highSuch a height is really insignificant for a tall building of more than 100 meters.

In fact, the telescopic height of the ladder has always been an important problem that plagues the rescue, Liu Langke was a construction engineer in the previous life, and there has been a deep study of the fire protection problem of the building, once the building is on fire, how to escape is naturally the most critical, and the second is the rescue of firefighters, which involves the height of the ladder.

Liu Lang knows that in 30 years, China's fire ladders can generally extend about 50 meters, up to nearly 100 meters, and the world's most advanced ladders can exceed 100 meters, which greatly improves the success rate of rescue.

Now the telescopic height of the ladder is only about 20 meters, and it has reached 100 meters after more than 30 years, this kind of improvement is not a little bit and a half, the most critical thing is the change of materials and power sources, the material has changed from the universal aluminum material to the light weight and high strength of the carbon fiber material, and the power has also changed from the use of people to push and pull into the hydraulic mercury collapse, the fundamental improvement of technology is the key, but there is also an important factor, that is, the later ladder in the structure is very different from the current ladder.

Now the ladder is just a straight up and straight down way, a twenty-meter-long ladder has five to six sections, each section is directly reinforced with strong bolts, but no matter how strong the bolt is when the torque becomes longer, it will not be able to withstand the huge torsional force and then directly shattered, so twenty meters is to the limit, and no longer it is necessary to go to the person, and a direct gust of wind will crush the bolt.

But ten years later, this connection has undergone a fundamental change, becoming a kind of connection similar to a rotating pulley, the bolt is no longer stressed alone, this structural change has made a change in the extension height of the ladder, from the longest twenty-two or three meters to about thirty meters, don't underestimate this short seven or eight meters, can save two floors of people at a critical moment.

Liu Lang has seen the structure of this kind of ladder, to be honest, very ingenious, just like the Transformers designed by Liu Lang, no one can imagine before it appears, but once it appears, anyone will instantly understand the truth, but then again, those well-known architects and designers have created works that others can't imagine before becoming famous? For these people, infinite imagination is the key.

Liu Lang believes that as long as this ladder is written in the form of a thesis, it will be enough to shock those so-called professors.

"Professor Ding, I have decided, what preparations do I have to make for the special enrollment of graduate students?"

Liu Lang didn't think about it and said directly.

"Hmm......... Well, since Liu Lang is so confident, then I will support you, the conditions are actually very simple, you need to prove your relevant academic ability, and you must also have a letter of recommendation from a relevant teacher, after all, although it is a special recruitment, you can't be qualified by anyone, you have a specialty in a certain aspect, you have to be proved by someone!"

Ding Huaizhong replied.

"Oh, my teachers are all in China, should they let them come to the United States?

"No, no, I'll hand it over to me, I'll write you a letter of recommendation, you can rest assured, and Mr. Knight, you can also write a letter of recommendation for Liu Lang to prove that his academic ability is no problem, after all, your role as a gold owner is stronger than mine in the eyes of some people!"

Ding Huaizhong said with a smile.

"That's natural, Liu Lang is a shareholder of our company, in my opinion, his ability is more than enough to be a professor, not to mention a graduate student, and the professors at Stanford are not as important as him to our company!"

Knight smiled and shook his head, he couldn't understand, why did Liu Lang have to take the graduate school exam? With his ability, a bachelor's degree is enough, and the graduation certificate is just to make his face look better at best, he wants money now, not to mention anything else, just the eight percent of Nike's shares can have hundreds of thousands of dollars in dividends this year, as Nike's stock price gets higher and higher, dividends are also increasing year by year, does such a genius need a graduate degree?

Knight really couldn't guess what Liu Lang was thinking.

Since Liu Lang has decided, let's start preparations, the first thing is to sign up, Ding Huaizhong took everyone to the place where they registered, and Liu Lang took out all the basic materials.

Liu Lang does not have an ID card, not that he is young, but now the country has not implemented the ID card system, the only document to prove his identity is the household registration book, if he goes out, he will provide a letter of introduction in the unit, but the letter of introduction of Huaxia University is naturally useless, but the country is still very thoughtful, and the household registration department of the Ministry of Civil Affairs issued a letter of introduction for him, which is also engraved with the seal of the household registration department, and such a letter of introduction is also unique in the whole country.

"Hehe, Liu Lang, the country still attaches great importance to you, don't lose this thing, it will have a great collection value in the future!"

Ding Huaizhong looked at the letter of introduction directly issued by the national civil affairs department and said with a smile.

"The state only began to discuss the implementation of the ID card system last year, and it is estimated that it will take half a year to implement it, and at that time every citizen will be able to have an ID card, and this kind of letter of introduction will naturally come to an end!"

"No, even if a citizen has an ID card, I'm afraid you Liu Lang won't have it for the time being, after all, you haven't reached the legal age yet, you must know that even in the United States, you have to be over fourteen years old to have an independent identity certificate!"

That's right, even if the state implements the ID card system, it is for citizens over the age of 16, and Liu Lang really can't have it at this age.

"Yes, but when the time comes, I'll let the state make one for me, I'm not a seven or eight-year-old child!"

Liu Lang waved his hand.

"Yes, I've never seen a child like you in my life!"

Ding Huaizhong smiled and shook his head.
