Chapter 264 Failed Question Battle
Eight o'clock in the morning.
Song He was studying at his desk, with a pile of math books borrowed from the library on the table.
He looked peaceful and calm. The stormy news in the outside world seemed to have nothing to do with him. He was just an ancient well, silently absorbing the rain of mathematics, and the water surface rippled slightly.
At the moment, his only task is to take the written test, which has no scope. He only knows to test mathematics. But mathematics is a vast and boundless forest, so he must seize the time to broaden his knowledge and chop down two axes on every tree.
There was a knock on the dormitory door, and then a yellow-haired head stuck its head in.
"Brother Song! The exam time and venue have been announced!" Shekov shook his phone.
Song He quickly grabbed his phone and looked at it. On the APP for the Yuecheng Project’s primary election, there was indeed a countdown!
[The written test (mathematics) for the Moon City Plan preliminary selection you signed up for will start after 71:58:30! 】
[Your examination location is: Jinling Institute of Technology Examination Room 01, Table 06]
[The exam is 10 hours in total and the amount of questions is relatively large. Meals will be provided in the exam room during the exam]
"There are three days left to review!" Song He frowned slightly, "I'm in the 1st examination room of Jinling Institute of Technology. I have to buy a high-speed rail ticket quickly!"
Shekov was overjoyed when he heard this, "I am also in the examination room 1 of Jinling Institute of Technology, and I am at table 7! But we don't need to buy tickets!"
Song He was startled, "How can we go there without buying a ticket?"
"Dial it down!" Shekov said.
Song He slid down the interface, and after a long list of clichéd examination room disciplines, a line of small words finally appeared.
[Please enter your current location. A special high-speed rail train will be arranged to take you to the test site one day before the test. This ride is free, but a valid ID is required for ticket verification]
After entering Jinghai University, an electronic ticket popped up immediately. Song He breathed a sigh of relief. The examination organizer had made thoughtful arrangements, and there was a special train to pick him up.
"Brother Song, I guess the ten-hour test will test your knowledge in a wide range of areas!" Xiekov speculated, "There are a few small questions in various mathematics fields. What do you think?"
"I'm afraid so." Song He looked serious.
"Brother Song, I have been losing recently, and now I want to win once." Shekov smiled evilly, "The mathematical knowledge I have is as vast as the frozen soil of Siberia!"
"The idea is good, but I'm afraid you can't win!" Song He squinted his eyes and looked at him.
"Can't win? How about we have a duel tomorrow?" Shekov said with a hidden smile.
"What is the title fight?"
"We have a high-intensity confrontation game in the St. Peter's Mathematics Department," Shekov said. "Two people face each other and take turns asking a knowledge point or a small question. The other party needs to answer it within one minute! Each person puts a card in front of them. There is a scoring sheet, and each question is worth one point. In the end, it’s up to you to see who scores more!”
"This is too easy!" Song He immediately pulled two pieces of paper from the side, "Do you have to wait for tomorrow? Come now!"
"Are you sure? Although I am not as good as you in topology, I have abundant knowledge in other mathematical fields! Why don't you take advantage of today to review and review?" Shekov's eyes were filled with murderous intent.
"Stop talking nonsense and sit down!" Song He patted the table.
Shekov sat down at the other end of the table, raised his pen, and looked at Song He across the table.
Their eyes were facing each other, with smiles on their faces, but invisible murderous intentions collided in the air, and the air in the dormitory seemed to explode with sparks of electricity!
"What is a function of a single complex variable?" Shekov took the lead in attacking.
"The generalization of the real variable function, the independent variables and the dependent variables are all complex values, and there is only one independent variable called a single complex function!"
Song He blurted out the answer, confidently drew a horizontal bar on the paper to score points, raised his head and asked, "Three common methods of stability theory?"
"Characteristic number method, differential and integral inequalities, Lyapunov function method!" Shekov also drew a scoring line.
In the first round, both sides were tied!
The two looked at each other and smiled, speaking faster!
"The main method for judging the stability of linear steady systems?"
"Nyquist stability criterion and root locus method! What systems are these two methods suitable for?"
"Single variable and multiple variables are acceptable! What about the stability of linear unsteady systems?"
"Lyapunov's second method! Sufficient conditions for judging the stability of large systems and multi-level complex systems?"
"Introducing the vector Lyapunov function! What are the advantages of the criterion in the frequency domain established by Popov?"
The dormitory echoed with the sound of verbal exchanges!
The two of them were sweating on their foreheads, answering each other's questions quickly. The intensity was like hitting a high-speed tennis ball. Amidst the banging sound, the tennis ball jumped back and forth in the mathematical field, changing strange arcs!
Song He wrote a lot of straight words on the scoring paper, and Shekov drew a lot of crosses.
It burned like fire for an hour, and the two of them didn't even miss a single hit, and both got all the points!
"The basics are okay!" Shekov was sweating profusely and his posture was tense. "I'm going to get more difficult!"
"I'll take the challenge too!" Song He smiled coldly and nervously clenched the pen in his hand.
After a short intermission, the artillery fire resumed, and the shells were even more powerful!
“What is the equivalent of the Cauchy sequence in Hilbert space?”
"Convergent sequences! What does Hilbert space provide an effective expression for any orthogonal system?"
"Polynomial expressions of Fourier series and Fourier transforms! What is the core concept of it?"
"Functional analysis! What can vertex operator algebra be used for?"
The intense back-and-forth questioning, math questions flying around like cannonballs, blew the two of them into disgrace.
The scoring paper is almost full. Song He's paper is densely covered with straight characters, and Shekov's paper is filled with crosses on both sides.
The two sides exchanged blows, and at the same time quickly tested each other's weak points, looking for opportunities to succeed.
Finally, Shekov caught Song He's flaw and attacked ferociously!
"Name 6 non-parametric statistical methods?" Shekov asked.
Song He suddenly got stuck, hesitated for a moment and then shook his head, "No! Ask one more?"
"What statistics are used in the goodness-of-fit test?" Shekov's eyes lit up.
"No." Song He looked unhappy, "Ask again!"
"What is the original model of the Markov process?" Shekov was surprised.
Song He was silent and shook his head.
"What is the definition of martingale theory?" Shekov started to beam with excitement.
"No!" Song He said angrily.
"In functional analysis, what kind of space is Banach space?" Shekov was overjoyed.
Song He frowned for a long time, but finally couldn't recall the answer.
Shekov laughed heartily, with arrogance written all over his face. He added more than twenty questions in a row, hitting the target every time!
The artillery battle between the two sides turned into Shekov's unilateral bombardment of Song He. Song He's cannon was completely misfired, and he could only be beaten passively, shaking his head over and over again with an ugly expression.
In the field he has studied, he can memorize all the knowledge he has seen. But the questions Shekov asked were all areas of mathematics that he had never touched before, completely blind spots in knowledge, and he was so dark that he could not see his fingers.
He was defeated for more than ten minutes, and he was as depressed as celery exposed to the sun.
Shekov felt so relieved that he felt so happy!
"It turns out that you also know a lot of things you don't know!" Shekov licked the corner of his mouth with a playful smile, "Sorry, I won once!"
"Let's fight another day!" Song He said shamefully.
"tomorrow?"
"Tomorrow is too urgent. Let's fight again on the train to Jinling the day after tomorrow!" Song He's forehead was pounding with veins, "I'm going to do a refresher on math in the past two days!"
"Fight again on the train?" Shekov smiled meaningfully, "The train is full of people going to take the written examination. Are you sure you want to embarrass yourself in front of everyone? We are good brothers. It would be awkward if I kill you in front of everyone. ?”
"Come on! I'm going to read a book!" Song He waved his hand to chase people away, "It's not certain who will lose then!"
Shekov stood up, laughed to the sky and went out, feeling happy from head to heels!
