The physics exam ended, and the chemistry exam soon began. Liu Lang handed in the paper ten minutes later. The idea of solving the problem was very clear, the process was clear, and there were no flaws. He still got full marks. Four students also answered the questions correctly, but there were some problems in the process.
Although there was a small problem, in the end an American student got full marks thanks to Holden’s intervention.
After completing the two subjects, Liu Lang had already won two championship awards, but two people tied for the championship in each subject.
Someone originally proposed a rematch for Physics and Chemistry, but Horton objected. It was not because of his conscience, but because he no longer had much confidence. What if two American players were eliminated in the rematch?
What to do? That’s really a slap in the face.
"The last subject is mathematics. It is more difficult to get the mathematics questions than physics... I hope Liu Lang makes a mistake!"
Now Holden can only pray.
The last subject was mathematics. When Liu Lang saw the last question, he was stunned again.
"Why are all these questions today related to the theory of relativity?"
This math problem is also very simple: there are four objects, namely two people, a speeding train and a burning candle.
A person is standing on a train that is speeding forward at speed V, looking at the candle five meters in front of him. Another person is standing under the car, also looking at the candle.
The speed of light is constant. Do the people in the car and the people under the car experience the same time? If they are different, please write down the relationship between them.
The question is very simple, but if you want to solve it, I am afraid that few students under the age of twenty can do it, unless they understand the special theory of relativity.
In fact, this question uses the Pythagorean theorem to prove the time effect problem in the special theory of relativity. As long as an object moves, there will be a time difference between it and the outside world. The faster the speed, the greater the difference. When it is infinitely close to the speed of light, for the outside world
In other words, it is in a state where time stands still.
The relationship between object time and external time can be proved using only one Pythagorean theorem.
The proof process is very simple. The moving train is a moving object, and the internal time is consistent. There is a time difference between the person standing outside the train and the train and the people inside. This difference must be calculated using the light beam emitted by the candle.
prove.
The light beam is emitted in a straight line and reaches the eyes of the person in the car. The time is just the time it takes for the light to travel the distance between them. This distance is a straight line.
But this beam of light is different when it reaches the eyes of people outside the train. The light propagates in a diagonal direction, and the variable of train speed is added to the time.
In a train, the two candle lights form a right-angled triangle. Each side is composed of speed and time. The right-angled side is the time of the people on the train, and the hypotenuse is the time required by outsiders. The two are in Pythagorean.
After calculating the theorem, a relational expression is obtained, which is the relational expression of the time effect in the special theory of relativity.
This relationship is very simple, just a simple Pythagorean theorem, but the premise is that you understand the meaning of this question, the difference in time? If you don't know the special theory of relativity, who the hell would have thought that there would be a difference in time?
Therefore, this question basically requires a person to completely abandon all past common sense when doing research, and only use the experimental conclusion to determine the facts seen, even if this conclusion is beyond common sense, for example, to prove that human beings
It's a dog. As long as the experimental process is error-free, the person will also believe the results.
However, Liu Lang happened to have read relevant books in his previous life. Although he did not know the proof process, the time effect did exist, so he solved the problem after a little thought.
The two questions took a total of fifteen minutes, which was already the longest time Liu Lang had ever spent, because these were two questions, compared to six questions when it took fifteen minutes before.
Liu Lang first took out a piece of chocolate and put it into his mouth, then stood up.
"ah!"
The person who cared most about Liu Lang was Holden. Seeing Liu Lang stand up, Holden's blood pressure went up.
"Have you finished answering again?"
"The exam is finally over!"
Liu Lang finally breathed a sigh of relief. He had been exhausted these past few days. The adult group of the Chinese team had finished the competition long ago, so now the participating teams of the China Intellectual Olympics have completed their tasks.
Liu Lang's paper was sent to the third floor. More than thirty professors gathered around and watched as the Chinese mathematics professor opened the envelope and took out the paper.
"Well, let's take a look, there are no mistakes, everything is correct, full marks!"
The math professor held it up high for the people around him to see. Yes, it was indeed a perfect score.
"Well, Liu Lang got full marks in all three subjects. I think no one has been able to do it so far! We happened to witness this feat. I believe that this Intellectual Olympics will definitely become the most special event in history.
For this reason alone, everyone should applaud to show respect for contestant Liu Lang!"
Ding Huaizhong was so happy that he shouted to the people around him.
"Yes, we are all witnesses. Who knows what achievements Liu Lang will achieve in the future? If he really reaches the heights of Einstein or Newton, I believe everyone will be recorded in the history books. By then, our
Future generations will be proud!"
The Chinese mathematics professor took the lead in applauding, and then others also clapped. It can be said that Liu Lang's performance was amazing. Everyone believed that as long as he could receive the best education, he would definitely become a mathematician in the future.
It may be difficult for great scientists to reach the heights of Einstein and Newton, but it may not be too difficult to win the Nobel Prize.
"Professor Ding, I didn't expect you Chinese kids to be so capable. It really opened my eyes!"
The professors present were not as hostile as Horton. They were also happy to have discovered a genius. In fact, this competition not only had a genius like Liu Lang, but also children like Tao Xuanzhe were very eye-catching.
The two young players from the island country are also very good, and they would have won in the past. However, they met Liu Lang and were completely overshadowed by Liu Lang's brilliance.
Until the bell rang at the end of the exam, no one handed in the paper in advance, and Liu Lang became the only champion in the mathematics competition.
The papers of other contestants were also judged quickly, and Tao Xuanzhe became the runner-up with 83 points.
I have to say that this mathematical genius is indeed very powerful. Although the question made him full of entanglements, he still thought of the Pythagorean theorem. Of course, Westerners call it the Pythagoras theorem.
It's just that I still haven't completed the calculation despite constant struggle, but this is already very good, much better than others who have no idea how to start. A ten-year-old child can become the runner-up in a world-class mathematics competition. If Liu Lang is not included, this result is
It was enough to become a record, but it was a pity that Liu Lang came and all the records were taken care of by him alone.
A four-year-old child won three championships in mathematics, physics and chemistry at the same time. This is an unprecedented thing, and everyone thinks it is likely to be unprecedented.
