Tian Hong didn't answer, his old face turned red again, and he nodded.

This problem of eating has been troubled from ancient times to modern times, which has made him suffer a lot, except for Li Shimin, Jiancheng Yuanji often makes fun of him.

Tian Hong didn't have the slightest solution to this problem, his body was born with divine power, and eating was also an additional function of his talent.

Ten catties of sauced beef requires a little preparation time, and everyone chatted, and Tian Hong asked directly about the rejection formation, he wanted to know how to explain the rejection formation with modern scientific knowledge.

"Mr. Qian, isn't the one I put on a perpetual motion machine?" Tian Hong's question is very straightforward.

"Tian Hong, the perpetual motion machine you posed for is not a real perpetual motion machine, because the transformation of energy is directional, no matter what movement in nature will produce heat, and the heat will spread to the surroundings and become useless energy. Without replenishment, any moving machine will stop. If this kind of perpetual motion machine can really be made, then you can get an infinite amount of power out of nothing without using any natural energy, in fact, the perpetual motion machine you are talking about, has constituted a kind of energy consumption, and the energy consumed is converted into a closed space, which is amazing, really amazing, but, unfortunately, it is not a perpetual motion machine......"

"Why not? I could keep him running for countless years. Tian Hong frowned.

"Hehe, the discovery of the law of conservation of energy has made people further realize that any machine can only transform energy from one form to another, and cannot create energy out of nothing, so the first type of perpetual motion machine is impossible to create. The perpetual motion machine mentioned by Tian Hong is still within the law of conservation of energy. Dr. Qian laughed.

"Say why." Tian Hong's questions are always direct and effective.

"It's very simple, you put the branches and stones like that, just using a principle of energy conversion that we don't know, and cleverly converting the matter of the branches and stones into energy, although we and I have cracked the mystery of its conversion energy, but we can be sure that when the so-called perpetual motion machine is running, the substances in the branches and stones are already consumed, well, by the way, Tian Hong, as long as the stones and branches move, the second time you swing, you have to set up their structure from the new, do you know why?"

"I don't know." Tian Hong looked dazed, he had never thought about this question, for those formations, it was completely instinctive, with the knowledge he mastered, he couldn't get to the bottom of it.

"Because, after moving a stone or a branch, it destroys the operation of energy conversion, if it is a real perpetual motion machine, as long as you determine a static energy output power, after moving, it should still be able to output energy when it returns to its original state."

"But...... But...... But why do they go on forever? Tian Hong wondered.

"Actually, no, when they are running, it means that the substances that they can produce energy have not been consumed, in fact, we, we have examined the composition of branches and stones, and their composition is different every second, which already shows that they consume energy because of their operation."

"The manufacture of perpetual motion machines fascinates researchers like a mirage, but all of these solutions have failed without exception. They have been going around in circles for years, and nothing has come of it. Through continuous practice and attempts, people have gradually realized that any machine that does work on the outside world consumes energy. Without consuming energy, the machine cannot do work......"

Dr. Qian was very patient and made up for Tian Hongxi's knowledge of the law of conservation of energy, and he knew very well that if he did not convince this mysterious teenager in this regard, it would be difficult for him to complete this mission.

"Teacher Qian, do you believe that some people can keep exercising without knowing that they are tired?" Tian Hong asked a secret that he had been hiding in his heart.

"Hehe, don't believe it, it's impossible, not to mention human beings, even if they are legendary immortals, they also want to eat incense in the world to replenish their divine power, let alone people."

"But I know of a man who has a power that will never run out, and I don't know how to explain it?" Tian Hong looked at Dr. Qian with a look of hope.

"I don't think there should be such a human being, I ask you, what is the maximum time that person can move?" Dr. Qian asked.

"This ...... I guess it's a few days. ”

"That's it, it's only been a few days, and you let him do it for a month, a year, ten years, a hundred years? In fact, people also have to abide by the law of conservation of energy, human strength comes from digesting food, if you say that the person is really powerful, or can maintain a long time of exercise, it can only mean that the energy reserves in his body are very large, just like a fat person has a lot of fat, and it is a truth that he can survive longer in the ice and snow. ”

"If the person you are talking about really exists, you can only say that there is a huge amount of energy in that person's body, which can last for a long time, and when needed, it can release this energy."

"I ...... Still a little bit ignorant ......" Tian Hong scratched his head.

"Haha...... If you don't need this energy, these energy will be stored in your body and become fat, some children have ADHD, like this, most of them can't get fat, because they consume all the ......energy."

"Oh......"

Tian Hong suddenly realized, he finally understood his special body structure, he eats an amazing amount but is not very active, perhaps, he has one more ability than ordinary people, that is, he usually stores his excess energy in a certain place in his body, and he can release it at will when he needs it.

"If you have any questions, just ask, and if I can't answer them, someone will answer them."

Dr. Qian looked at Tian Hong with a smile, he saw too many people like Tian Hong, because these people have some special abilities, and some abilities cannot be explained by science, which will make these people with abilities walk into a misunderstanding, they will think that science is just a false proposition, and his responsibility is to let these people return to the normal trajectory of life, carry forward their abilities, and serve the country.

"Dr. Qian, do you believe in ghosts and gods?" Tian Hong pondered for a moment, stared at Dr. Qian's eyes and asked.

"Tian Hong, can you change the topic?" Dr. Qian smiled bitterly.

"Why?" Tian Hong couldn't help but be stunned, he couldn't imagine that Dr. Qian would avoid this topic.

"Tian Hong, I'm not evasive, about ghosts and gods, it's difficult to explain, if you look at it from a scientific point of view, ghosts and gods are pure nonsense, but, in nature, there are many things that we can't explain, others can't prove the existence of ghosts and gods, and similarly, we can't prove that there are no ghosts and gods, so your question is really hard to answer......" Dr. Qian paused and said: "Also, with my identity, it is naturally impossible to go deep into this topic, but I personally believe that the theory of ghosts and gods has a long history." There must be a reason for the absence of wind and waves, but we can't open that door......"

"Hehe, yes, we can't open that door, okay, Mr. Qian, if you have any questions, just ask, as long as I can answer them, I know everything...... Hey, here'...... the dishes."

Dr. Qian was just about to speak, when he saw that Tian Hong's eyes suddenly became extremely bright, and when he looked back, it was the hotel waiter who was serving, so he quickly shut up......
