After a long time, he exhaled heavily and said, "I can't do this topic, so I ask Lord Yang to teach me!" “

Yang Zheng saw that the two of them looked a little more earnest, and the pride just now was more than half, and he nodded secretly and said, "It seems that the effect is obvious?" Seeing that you are so humble in asking for advice, it doesn't hurt to sue you! After pondering for a moment, he said: "After this man named Archimedes received the king's order, he forgot to eat, sleep, bathe, and heal, and was obsessed with it, and even muttered in his dreams: "The crown...... King...... Jeweler...... Silver...... ......A few weeks later, Archimedes was unkempt and his wife drove him into the bathroom. When Archimedes was immersed in the water, he suddenly felt that he had lost weight, and with a gentle effort, his body was able to float...... At this time, his head was still full of crowns...... King...... Jeweler...... Gold...... Silver....... The body sinks and floats for a while, and the water level of the bathtub rises and falls......

Archimedes suddenly turned over and jumped up, shouting: "There is a way, there is a way!" He ran naked to the palace, leaving a wet trail on the way...... Madame was really anxious this time, and muttered, "It's crazy, it's crazy," and then chased after her. The people on the street didn't know what was going on, and they all followed after them. “

Everyone was amazed and whispered, Xing Kuan said curiously: "Could it be that this answer is in this water?" ”

Yang Zheng said sincerely: "Lord Xing is worthy of being the top talent, you guessed right, the answer is in the water?" ”

Everyone became more and more curious, obviously they wanted the weight of gold, how could the answer be in the water? They couldn't think about it, so they had to look at Yang Zheng.

Zeng Heling's face was a little ugly because Yang Zheng had praised Xing Kuan for his talent just now, and he wanted not to listen, but he was very curious about the answer to this strange test question, so he snorted at Yang Zheng, and still listened attentively.

"That's it, I can't let go of that little champion shelf, my face is really a harmful thing!" Yang Zheng shook his head, sighed lightly and continued to solve the mystery for everyone, only to hear him say: "It turns out that Archimedes found a solution to the crown problem by the overflow of the bathtub: the same substance of the same mass is soaked in water, and the volume of the overflowing water should be the same. If the crown is placed in water, the volume of the overflowing water should be the same as that of a gold nugget of the same mass, otherwise the crown must be adulterated.

Archimedes ran to the palace and immediately found a basin of water, and found a piece of gold and a piece of silver of the same weight, and soaked it in two basins, and the water overflowed from the silver was almost twice as much as that of the gold, and then he soaked the crown and the nugget into the basin of water, and the crown overflowed with more water than the nugget, and it was obvious that the mass of the crown was not equal to the mass of the nugget, and the crown must have been adulterated. In the face of the hard facts, the goldsmith had to bow his head and admit that the crown was indeed mixed with silver. The mystery of the annoying crown has finally been solved. At this time, after Yang Zheng's careful explanation, many people began to understand the truth, and constantly praised Archimedes for his wisdom, but Zeng Heling snorted coldly and said: "It's just a temporary trick, it's nothing?" “

Yang Zheng knew that it was not easy for these champions to admit that they were inferior to others, but fortunately, he was not in a hurry, and said with a smile: "So, Lord Zeng is not convinced?" “

Zeng Heling has had the reputation of a prodigy since he was a child, and now he is the champion of everyone's envy, the pride of the sky, but he doesn't want to be crushed by a little-known hairy boy, and he can't help but be a little unconvinced, and said: "It's okay if you want me to take it, unless Lord Yang has another test question, otherwise I won't be able to obey what I just said!" “

"My day, if you can't compare, you can cheat, is this also the ability of the champion?" Yang Zheng muttered as if he was smiling, and said: "It's okay, the lower official said just now, there are two test questions today, and there is no faith in his words, how can he stand!" These words seemed to mean something, Zeng Heling's face was hot, but he snorted coldly.

"Less friction and faster questions, right?" Zeng Heling glared at him and said.

Yang Zheng smiled and said, "This second question is much easier, Lord Zeng should listen to it?" ”

Zeng Heling snorted: "Less nonsense! ”

Yang Zheng shook his head and said, "Your Excellency, you might as well listen to it, how to answer this test question of the lower official?" ”

Everyone happily agreed, Yang Zheng nodded and said: "After solving the gold problem, the king encountered another problem, he has a big boat, this boat was made by King Henon for the king of Egypt, it is large and quite heavy, because it can't be moved, it has been stranded on the coast for many days, and the king found Archimedes and said: "You are the smartest person in the world, you must have a way to transport this big ship to the sea, and this matter will be handed over to you!" Speaking of this, Yang Zheng was like a storyteller, glanced at everyone with a smile, and said, "Tell me, how can Archimedes push this big ship to the sea?" “

Everyone immediately lowered their heads and thought about it, Zeng Heling had a headache, glared at Yang Zheng with annoyance, and said in his heart: "This is also a freak who came out of nowhere, full of strange topics, this is not a mistake in stealing chickens?" "Although I scolded in my heart, I had to use my brain to think, this ship is large, quite heavy and can't be moved, so it can only use manpower, but how much manpower should be needed for such a big ship?"

"That's easy?" Zeng Heling suddenly said loudly.

Everyone was bowing their heads and pondering, but finally heard someone answer, and under curiosity, everyone raised their heads and saw that it was Zeng Heling, and each nodded and said: "Sure enough, it is the best talent, and such a strange topic will also be admirable?" ”

Yang Zheng was also a little surprised, and said in his heart: "Could it be that I was mistaken, this guy is actually a master of both civil and military cultivation, and he also understands the principle of leverage!" In fact, there was no shortage of scientists in ancient China, and Mozi had conducted quite systematic research on plane mirrors, concave mirrors, convex mirrors, etc., and derived a series of basic principles of geometric optics. He pointed out that the plane mirror forms an image of the same size, symmetrical from near and far, but reversed from left to right. If two or more flat mirrors are illuminated in the opposite direction, repeated reflections will occur, resulting in an infinite number of images. The imaging of the concave mirror is to form a positive image within the "middle", which is large from the far from the "middle", small from the "middle", and as large as the object at the "middle"; Outside the "middle", it is an inverted image, near the "middle" is like a large, far "middle" is like a small. Convex mirrors only form a positive image, with large near mirrors and small far mirrors. Although Mozi has not yet been able to distinguish the difference between the center of the sphere and the focal point, and confuses the center of the sphere with the focal point, his conclusion is basically consistent with the imaging principle of modern spherical mirror, so he is surprised and can't help but have some expectations.

"Oh, since Master Zeng has the answer, why don't you tell me about it?" Yang Zheng turned his head and asked.

Zeng Heling said: "What is there to say about this, this ship is large, quite heavy and cannot be moved, only with the spirit of Yugong moving mountains, just dig up the beach?" ”

"Foolish man moves mountains?" Yang Zheng was suddenly disappointed, and snorted: "The method is a good way, but how many generations is Master Zeng going to move this boat back to the sea?" “

Zeng Heling's face flushed, but he felt that although his method was a little stupid, it was not a good method, but it was not necessarily a better way, and he said with a stiff neck: "Although this official's method will take some time, it is a good method!" After a pause, he said, "I don't think Lord Yang may have a better way than this?" “

Yang Zheng shook his head and smiled bitterly, slowly paced a few steps forward, and said with a smile: "Does Lord Zeng want to know a better way?" “

Zeng Heling snorted and said, "Lord Yang just said it?" I don't believe there is a better way in the world? ”

Yang Zheng was a little depressed, he was proud to be like this, it can be seen that the champion has seen what he has become in the past few years, no wonder there are only a few of China's more than 700 champions who can achieve great causes, just for this stubborn attitude, what else can he grow, Da Ming is in danger, and sighed and said: "Is there a good way, Lord Zeng can listen to it!" ”

Everyone chattered non-stop, and as soon as they heard Yang Zheng's words, they immediately quieted down, and their eyes looked at Yang Zheng, Xing Kuan glanced at Zeng Heling and then at Yang Zheng, and said in a low voice: "Lord Zeng is only afraid that he is going to lose!" “

Yang Zheng pondered for a while, he intended to let everyone hear Archimedes' method, so his voice was louder than just now, and he could only hear him say aloud: "After Archimedes received this task, he first asked the craftsman to install a set of delicately designed pulleys and levers on the front and rear of the ship. Then he called more than a hundred people in front of the big ship and grabbed a rope, and he asked the king to pull a rope, and the big boat actually slowly slid into the sea......? ”

Where have everyone heard of such a method, they were surprised, but they couldn't understand how the boat was slipped into the sea, because of their faces, but they were embarrassed to ask, so they had to look at Yang Zheng.

"How is this method, Lord Zeng?" Yang Zheng ignored everyone, stared at Zeng Heling with a smile and asked.

Zeng Heling said: "It's not necessarily so clever! “
