Chapter 227 Hands-On Programming
"You, you, you are..." Shekov stuttered.
"I'm too tired from doing the questions. Get some oxygen." Song He explained.
Shekov scratched his yellow hair and said, "I drink when I'm tired, and you take oxygen. It looks like your habits are healthier."
He walked behind Song He and leaned over to read the paper on the screen.
Some familiar formulas came into view. After a brief hesitation, he recalled something and his expression changed.
"This paper is related to Calabi's conjecture! Can you understand it?" Shekov asked.
"I don't understand, I'll learn slowly." Song He frowned, "Have you ever learned it?"
"I tried to study on my own in my sophomore year. It was so difficult that it made me sick, and I could only learn a superficial understanding." Shekov advised, "You don't have to waste time on overly difficult knowledge. Learn the simple ones first, and then learn them again in two years." This. Let’s have breakfast?”
"Not hungry." Song He raised his pen, wrote a long list of formulas on the paper, and frowned to deduce.
Shekov looked at the formula curiously, which was incredibly difficult.
Obviously Song He was also stuck, hesitating, writing twice in a long time, and then crossing it out quickly. He looked like a poor student who was in a dilemma in the examination room, without the ease and ease of a top student.
"Why do you need to learn these extra things?" Shekov was curious. "You can't learn it."
"I'm looking for a way to transform the space window cleaner program," Song He said confidently, "I can learn it!"
Shekov was suspicious, "Have you got an idea?"
"Not yet, because I haven't learned it yet."
Shekov left the dormitory and returned after a while, bringing his laptop over.
He sat next to Song He, quickly found the same paper, and studied it with great concentration!
In the past few days, Professor Wang has been ill in bed, and Song He has been in retreat to study the questions, so that Shekov is alone in seeking defeat. No one can beat him on the window cleaning program!
But at the same time, Shekov was having trouble making progress. In the past two days, he had been frantically modifying the program. However, after the modification, either the performance dropped, or the space window cleaner malfunctioned, and it seemed that he had hit the ceiling!
As a result, he was confused and at a loss as to what to do, and almost wanted to give up on the research process.
At this moment, Song He was taking oxygen to study for a new thesis, which made Shekov feel a strong sense of crisis!
He believed that there must be a reason for Song He to work so hard. Don't worry about it, just keep up first!
The two of them studied side by side. They looked friendly on the outside but had strong fighting spirit in their hearts!
Song He pulled a piece of exercise paper from the side and slapped it in the middle of the table.
"If you can get all the five questions above right, you will almost have a thorough understanding of this paper!"
Shekov decisively took a blank piece of paper and quickly copied down the five questions.
When he was copying the questions, he felt the terrifying difficulty, and couldn't help but change his face slightly, "Where did you get such a difficult question?"
"I found it accidentally when searching for thesis materials." Song He said, "The question was asked by Bruce Bennett, an algebraic geometry scholar at Stanford. This person is the apprentice of Fields winner Hironaka Heiyu."
Shekov was surprised, what a powerful information search ability! It makes sense when you think about it, compared to students with academic background, he is purely self-taught! If he is poor at finding information, how can he learn on his own?
The two of them studied the paper while trying to solve five questions.
Song He hardly used scratch paper, and it took him a long time to write a piece of paper.
Shekov kept writing throughout the whole process, writing one piece after another. He quickly used up the few scratching paper stocks on the table, and ran to the next door to bring back a large pile of white paper.
He brought along a large bag of wafer biscuits and a small metal flask. A mouthful of biscuits and a mouthful of wine would explode in heat and replenish his rapidly depleted physical strength.
Song Hexue was hungry, so he reached out to grab the wafers, and as he ate, he put the metal flask to his mouth, and the smell of strong alcohol hit his nostrils.
"Thank you, I don't smoke or drink." Song He refused.
"You don't smoke or drink? How can you still call yourself a man?" Shekov's eyes widened.
Song He was speechless, studying silently.
The morning passed quickly, and the two of them were immersed in math problems, discussing out loud from time to time.
"Shekov, you made a mistake here. The result should be a two-dimensional manifold, and every part of it is similar to the Euclidean two-dimensional plane."
"Z is a complex number! In the form of x+iy, then f(z) should also be a complex number." Shekov frowned and retorted, quickly drawing on the paper, "Look, if you set the x and y axes Real part and imaginary part, z-axis is set to the real value of f(z)..."
Song He didn't wait for him to finish the drawing and smiled, "What you drew should be a deformation of the Riemann surface."
"Yes, the Riemann surface is a one-dimensional complex manifold..." Shekov stopped mid-sentence, vaguely thinking of something.
"One complex dimension corresponds to two real dimensions, so a one-dimensional complex manifold is a two-dimensional manifold, and a Riemann surface is a two-dimensional manifold. This is basic knowledge!" Song He teased.
Shekov scratched his yellow hair helplessly, "I'm confused, I'm confused, it's a low-level mistake!"
He hurriedly recalculated, but just after writing a few pages, Song He next to him opened his mouth to correct his mistakes again.
"You should first deduce from space to topological manifolds, then to differential manifolds, stop to do relevant calculus operations, and finally jump to Riemannian manifolds."
"You also made a mistake in the quadratic relationship between the distance formula of space and the metric. There was a problem with the vector product of the Riemannian manifold later. You made the vector product of Euclidean space. The two look very similar. You have to pay attention!”
Shekov looked a little worried.
He turned to look at Song He's exercise paper and accidentally solved the first three of the five questions!
Even the process of solving the problem was extremely concise, I wrote a few strokes with my mind jumping, and finally the result was straight away!
Shekov had just solved the first question, but when he came to the second question, he made a lot of mistakes, and his heart sank!
The gap is huge!
No, cheer up and catch up as soon as possible!
Shekov accelerated his calculations and tried his best to solve the problems, even his blood pressure soared!
The progress was made bit by bit, and he struggled to finish the second question. He did not dare to relax and fought against exhaustion to attack the third question.
Just as he started, there was a "pop" sound next to him, and Song He put down the pen!
Xiekov turned his head and his expression suddenly changed. While he was doing the second question, Song He solved the fourth and fifth questions in succession. He was done!
Then, he was horrified to see Song He plug in the USB flash drive into the computer and bring up the artificial brain programming!
"Got an idea?" Shekov tried in a panic.
"The thinking is clear!" Song He smiled broadly.
Shekov's mind was completely confused and he could no longer finish the problem. For the whole morning, he tried to catch up, but was left far behind. Although he didn't want to admit it, he felt that the reason why he couldn't catch up was mainly due to the mental gap, rather than the time difference.
Next, Song He performed an operation that shocked Shekov's eyes.
With one click of his mouse, he deleted 80% of the programs without blinking an eye!
The originally vast and bright point cloud was deleted into a large area of dark void in an instant!
"Delete so many?" Shekov was shocked, "Are you crazy?!"
"If you don't break it, you won't build it!" Song He said, clicking the mouse quickly!
In the crazy spots like a goddess scattering flowers, brain cells of different colors fill the darkness again.
Shekov stared blankly, and was soon surprised by his incredible hand speed.
Song He has set up shortcut keys for most of the keyboard, and keeps typing with his left hand, switching programming functions at a high speed twice a second.
At the same time, the mouse on his right hand became even more violent, clicking like a machine gun, and the afterimage appeared quickly!
Shekov's hair stood on end. He asked himself, he couldn't write programs at this speed at all, not even half of it!
How agile a brain is required to perform such an operation?
Could it be that... Song He can really break through the limits and once again improve the performance of the space window cleaner?
