Chapter 433 Ye Han's Small Means A Big Step In The World
It’s so incredible!
Because the three-body problem is too difficult!
Although it is only bound by the simple and straightforward Newton's laws of motion.
However, like the NS equation that controls fluid motion and the BTE equation that controls the motion of a large number of molecules, it is a partial differential equation that cannot be solved accurately so far. It is a dark cloud problem that still exists in the fields of mathematics and computers.
Not only mathematicians and physicists can't figure it out, but computer scientists can't come up with an answer through massive simulations using supercomputers.
Otherwise, the weather forecast would be accurate, the stock market would be predictable, and chaos would disappear...
How difficult is it exactly?
As mentioned before, Einstein's field equations of general relativity are very difficult. After more than a hundred years of calculation, scientists have only come up with a few sets of accurate solutions.
To be more specific, the field equation is composed of ten equations;
The motion equations of each celestial body in the three-body problem are six first-order ordinary differential equations. Adding the three together, there are eighteen equations;
Although the difficulty of a single equation is less than that of the field equations of general relativity, when combined, the difficulty skyrockets.
Since the birth of Newtonian mechanics, the three-body problem has emerged; in 1885, King Oscar II of Sweden formally proposed the many-body problem; and now... More than three hundred years have passed, and countless mathematicians and physicists have
Computer scientists have studied this problem in depth.
However, until 1993, only three types of solutions were discovered, including: the figure-of-eight family, the Lagrangian-Eulerian family [that is, the family of solutions that derives five Lagrangian points] and the Brook-
Henon tribe.
In 1993, through computer simulation, scientists came up with thirteen new types of solutions...
However, a complete solution is still far away.
Because these solutions are all special solutions, they are special periodic solutions that can only be obtained under ideal circumstances given appropriate initial conditions, starting points, speeds, etc.
The general solution to the three-body problem is non-periodic infinite chaos.
The above is just a three-body problem.
The four-body problem has one more body than the three-body problem, so the complexity naturally soars exponentially again.
In reality, since the three-body problem has not yet been understood, few scientists have tried to go beyond the three-body problem to the four-body problem.
Because the limited three-body problem requires reference to the general solution to the two-body problem; the solution to the four-body problem also requires reference to the three-body problem.
It's like building a building. The second floor is not finished yet, so you go directly to the third floor. How is that possible? This is not a normal sequence at all.
Therefore, no one paid attention to Ye Han's research.
It wasn't until they started to pay attention to it that the mainstream scientific community was shocked!
Ye Han’s four-body special solution actually exists!
They analyzed and verified again and again, through mathematical methods, through computer simulation...
And all the feedback told them that the answer was correct and there was no problem.
If there is no problem with the answer, then it is someone else who has the problem...
Even if such a result has no derivation process and can pass verification, it is enough to enter an S-level publication. However, it is rejected one after another, and even such a small-scale publication cannot be published?
As a result, many publications that had rejected Ye Han's manuscripts began to tremble.
Especially those water journals.
The opportunity is in front of me, but it’s useless!
What the mainstream scientific community is even more curious about is that there is neither a laboratory dog nor supercomputer authority, and even an IQ of only 105. How did Ye Han come up with the special solution to the five or six races?
Not to mention relying on hard work, modern technology has long left the stage where ordinary people can achieve success by hard work;
Not to mention relying on hot blood, this is not a hot-blooded show...
"It's actually not difficult."
Ye Han didn't hide anything and announced his answer when asked.
"When I realized that my brain would never be able to think quickly and efficiently again, I started looking for some alternative way."
This is not impossible. Computers, for example, are tools made by humans to assist thinking and calculation.
However, computers have obvious shortcomings. Their way of thinking is too rigid, there is no room for mistakes or associations, it is difficult to carry out logical deductions beyond the preset programs, and there are also various undecidable problems...
The key is that computers can only provide assistance. If you want to rely on computers to creatively solve scientific problems, 99.999% of the creativity still relies on the human brain.
So it's not enough for Ye Han.
"In the end I chose a very interesting creature - slime mold!"
When it comes to this, ordinary people may not understand it, but many scientists already understand it.
Slime mold is really a magical and extremely interesting creature!
How amazing is it?
Although it is a single-celled organism, it inherently knows how to build an energy network with minimal consumption.
The Tokyo Metro, which Yue himself spent decades building, provides the optimal route in just a few hours, and is even more reasonable than the actual design.
It can control the robot, know how to navigate the maze, and strictly follow the optimal nutritional ratio when eating. If the food ratio is wrong, it will mix a variety of foods to create a taste that best suits it.
It is like a creature that is born with programming, with many algorithms such as ant colony and annealing engraved in its genes.
What's even more incredible is that its memory can be passed down in a very magical way.
Divide a large slime mold into small pieces, and each small piece will have the memory of the large slime mold. It is clear where to go and where to go;
If a small piece is integrated into a large slime mold, the memory of the small piece will be inherited and accepted by the large slime mold, and the walking skills will also be mastered...
Moreover, all the incredible things mentioned above are not just rumors. They have been repeatedly verified by scientists and the papers have been published in Nature and Biophys AS.
Of course, although slime mold is magical, it actually has great limitations. It is more similar to a quantum optimization algorithm, which only has expertise in solving specific problems and lacks versatility.
Therefore, if Ye Han wants to use it to assist in the calculation of the three-body problem or even the four-body problem, he must establish an experimental method from scratch and use the strengths of the slime mold in the right direction.
This is bound to be an arduous, long, boring and torturous process!
But Ye Han had no choice.
If he lacks IQ, has no supercomputer authority, and is not qualified for quantum computing, slime mold is his most economical and convenient choice.
From verifying the solution to the original two-body problem;
To construct a three-dimensional model through aerogel, establish a reaction-diffusion balance through the Turing pattern mechanism that also needs to be described by partial differential equations, successfully enter the three-body field, and verify the sixteen solution sets;
Then continue to increase the complexity of the system and try to solve specific periodic solutions of four bodies, five bodies or even more bodies...
Ye Han spent ten years!
Although the illusion of inner demons blurs the world view of time and even logic, Ye Han is the origin of this world.
If he strictly follows logic, the world will follow logic; if he strictly waits for time, time in this world will not easily cause trouble, unless the director behind the scenes interferes.
Of course Su Xingmou didn't.
No one knows how serious Ye Han is about research than she does.
She will only occasionally harass, but will never interfere.
Let Ye Han think and play, and at the same time accumulate the emotional power needed by Xuanxiao Flower.
After the promotion of Ye Han and Su Xingmou's incident, many melon-eating viewers realized that there are magical creatures like slime mold in the world. The key is that they are easy to use and not expensive. Free shipping for dozens of dollars. Many people keep them as gardeners.
It has long been popular among the small circle of scientists.
For a time, Taobao was very expensive, and many merchants made a lot of money.
Ye Han constructed a slime mold diffusion model in three-dimensional space and added a reaction balance of inhibitors to more flexibly screen specific solution sets, which also opened up a new way of thinking for them!
Although computer technology in 2030 will be more developed and faster, most of the algorithms are still flat or even one-dimensional - by weaving and processing nearly infinitely long paper tapes, the answers to the desired questions can be obtained.
But in fact, the efficiency is not very high, the waste is huge, and it is quite unintuitive.
Ye Han's slime mold model may not be as fast as quantum computing, but it has many modulation methods and is much more versatile than quantum computing;
It may not be as convenient as a general-purpose computer, but it can approach the essence of many problems and even break through the upper limit of current computing power;
And it’s cheap enough, has low energy consumption, and is pollution-free…
It can be said that it has opened up a new computing field.
Not to mention his previous contributions, the expansion of a new scientific field is enough to put him on the altar again.
For a while, it was said that he had been nominated for the Nobel Prize in Chemistry. After all, as we all know, the Nobel Prize in Chemistry is a biology prize, and the slime mold model undoubtedly belongs to the category of biology;
Some people say that he is very likely to win the Turing Award, because the slime mold model clearly exists because of chaotic computing;
It is also said that the Fields Medal is also being considered for awarding him, because the general solution to the four-body problem is obviously a mathematical problem, and Ye Han is only in his early thirties, which is far from reaching the upper limit of Fields;
In addition to his achievements, his experience is obviously even more legendary——
Although the body is disabled and the will is strong, never give up;
What is lost is the east corner, and what is gained is the mulberry tree;
The book has its own golden house, and the book has its own beauty like jade...
For a time, Ye Han's popularity skyrocketed, and many people even began to discuss the question of whether Su Xingmou was worthy of him?
Although based on his wealth, status, appearance, and social influence, there is nothing that Su Xingmou is not worthy of. However, considering the inheritance of future generations and the continuation of genius genes, Su Xingmou, who has an IQ of less than 100, is obviously not a qualified candidate...
So before the host said anything, the fans on both sides started fighting, despising each other, and the quarrel was so intense that they collapsed.
But all of this barely interfered with the growth of Xuanxiao Flower...
Instead, he became a staff member of the Microscale Research Institute again, and even became the leader of the latest biological computing project team. From then on, there were many problems to solve, many bacteria to use, and many people to help him... Ye Han was very excited.
A few bloomed.
The turmoil on his side has calmed down, and he kisses me happily.
But in other parts of the world, it is like a butterfly flapping its wings, and the balance of the three-body solution is broken, and it cannot be calmed down no matter what.
The key lies in Ye Han.
Because his clarification exposed a certain truth that a certain country had tried hard to hide for ten years.
