Technology invades the modern world

Chapter 17 Five divisions? No, five hundred divisions!
"It's $1000, indeed. 4V is quite generous, having taken away a large amount of gold and cultural relics from the mainland. They've really spared no effort in attracting talented Chinese people in America."

After Zhou Shukai left, Lin Ran took out the US dollars from the envelope and thought.

The real purchasing power of $60 in 1000 years is at least equivalent to about $2020 in 12000.

In addition to the US dollars, the envelope also contained a letter of appointment inviting him to serve as a distinguished professor at Tsinghua University.

It's like a pillow is given to you just when you feel sleepy.

If he hadn't gone to the island, Lin Ran really couldn't imagine how to establish contact with China in this era.

At this point in 1960, China and America had not established formal diplomatic relations, and there was not even an office here.

If you want to establish connections with China, there is only one way, and that is to find a chamber of commerce that is close to China.

Chinese people in America have various chambers of commerce, large and small, and some of them are definitely close to China.

But the problem is that he took the initiative to contact such chambers of commerce. Although the chambers of commerce are on good terms with China, there is no guarantee that all staff members of such chambers of commerce can keep secrets.

Even if Lin Ran just solves an equation for China, he may be investigated.

At present, it is extremely difficult to establish contact with China.

But with 4v as a springboard, the situation is completely different.

China definitely has far more people in the 4V field than America.

More importantly, Lin Ran went to 4v to be a distinguished professor and to give lectures there.

When a student asks a question during a lecture, it's normal for a professor to answer it, right?
The equation the other party asked about is related to ballistic calculations. How do I know?

What? You said that when I was teaching at Tsinghua University in 4V, my students came to ask for advice, and they passed what I taught back to mainland China and used it in the design of intercontinental missiles?

This is the perturbation theory related to intercontinental missile launches. This is a simplified model of the Navier-Stokes equations used for aerodynamic heating. If this finite difference method optimization is used for ballistic simulation, it can save 80% of the time.

At the time, I thought the problem was just a simple partial differential equation.

When the investigators asked, "Is this simple?" Lin Ran, the prover of Fermat's conjecture and the youngest Fields Medal winner, replied, "Of course it couldn't be simpler."

As for how to accurately select the students who will pass the news back to mainland China from the many 4v students, this naturally depends on the information being released in the future.

Lin Ran also very much hopes to be able to provide some "little" help to China of this era while protecting himself.

"An intercontinental missile that can directly threaten the American mainland would be great.

The range of the Dongfeng-1 was only a few hundred kilometers, and it was not until the 5s that the Dongfeng-80, with a range of over kilometers, was successfully developed.

With my help, it would probably be done in the 1960s.

As for being investigated, as long as you can fully prove your worth and have a strong bond with the Jewish community, it won't be a big problem.

It can even drag the Jewish community into this. If things get really bad, there's a way out."

After receiving a professorship offer from Columbia University and $1000 in start-up capital from Zhou Shukai, Lin Ran rented a house next to Horkheimer's home and moved in.

After having a place of his own, Lin Ran finally felt a sense of security and belonging to this era.

"The next thing to do is to make a name for myself in the mathematics community through Fermat's Last Theorem and the extended Langlands Program, and then wait for Kennedy to be elected at the end of this year, and for the Soviet Union to take the lead in achieving manned space flight next year, and then find an opportunity to get into NASA." Lin Ran thought.

After carefully studying the capabilities of the "Door", Lin Ran deeply realized that his greatest asset in jumping through the timeline was technical information.

An 18-gram USB flash drive can carry more than 18 GB of technical data. Its value cannot be measured in money and is not comparable to grams of gold at all.

The most valuable thing he could bring back from 1960 to 2020 was only technical information.

Who says that previously abandoned or neglected technology paths are necessarily wrong? Or that they are incapable of developing valuable technologies?

The popular range-extended engine for new energy vehicles can be traced back to 1900, but has been placed in a pile of discarded old papers, waiting for Chinese car companies to restart it and give it new life.

Technological evolution has never been a one-way process of elimination followed by progress, but rather a spiraling upward process. Many previously abandoned technological paths have been revitalized by new materials, new demands, or interdisciplinary integration.

The reason why Lin Ran chose to start with NASA was partly due to his personal interest in aerospace, and partly because NASA controlled the most scientific research resources at present. Every year, scientific research funds equivalent to about 2% of America's GDP are burned through NASA. He controlled such a behemoth to serve his own purposes.

And who says these new technological routes, which were reignited by me in 1960, cannot be revived in 2020?
What Lin Ran most wants to reactivate is the ternary computer technology route.

Although the ternary system has been eliminated in history, with artificial intelligence in full swing today, who can guarantee that this technical route will not be pulled out again and revitalized in the era of artificial intelligence?
The so-called advantages of the ternary system include that the logarithmic efficiency of representing numbers in the ternary system is higher than that of the binary system. For example, the decimal number 10 only requires 3 bits (101), while the binary system requires 4 bits (1010), and information redundancy can be reduced by about 25%.

As the chip advancement process becomes increasingly difficult, ternary system may be a good technical route.

What's more crucial is that in the process of simulating neuromorphic computing, three-state logic can naturally simulate the activation, inhibition, and resting states of biological neurons, making the synaptic model of brain-like chips more accurate.

Similar technological routes abound, starting from utilizing NASA's resources, and then utilizing the resources of the entire world, leveraging funds, organizations, talents and businesses to operate according to one's own will, and the resulting technology will be fed back to 2020. Just thinking about it is enough to make Lin Ran excited.

As for such a technological empire, it naturally cannot be placed in America.

Choosing the middle ground would be a good choice.

Lin Ran has figured out the entire plan during this period. With the help of the Jewish power and the rescue of Kennedy when he was assassinated, the Jewish community, the life-saving grace and his own abilities, the White House is willing to hand over the highest authority of the rocket control panel to him.

Wait until eight years later, when the Donkey Party steps down and the Elephant Party comes to power, and then go through the door to Hong Kong to start his own technological empire.

Because of this, by that time, Lin Ran's value wouldn't be five divisions, but fifty. If China didn't have something real in hand, it really wouldn't be able to protect him.

So when I wanted to sleep, Zhou Shukai handed me a pillow in time. I was worried that I couldn't establish contact with the Chinese side.

　I'm afraid that everyone thinks it's rare for me to write about black technology to help the development of America, so I'd like to explain that I only started with NASA and will return to Hong Kong in the 70s to build a technology empire.
