"Mr. Aristotle thinks that there is no emptiness in this world, and you think that the world is full of different beings, and that movement takes place in the mutual process of these things"

Bai Dong ignored the excited Aristotle, and smiled slightly: "Then let me ask Mr. Aristotle, what power do you think the boat relies on to sail on the water?" ”

Suddenly jumping directly from the discussion of free fall to the question of the boat, Aristotle was stunned and replied instinctively: "I have done experiments, and the water has a floating force on the wood, and the power of the oars and the wind make the boat move on the water, what can be the problem with this?" ”

"Hehe, can the ship float because it is made of wood? We'll come back to that later. If Aristotle could have taken into account the buoyancy of water and the force of the wind, why did he not take into account that air is also 'buoyancy'? When an iron ball or a feather falls, this buoyancy becomes resistance? And why didn't you take into account that there is also wind in the air? Drag and wind affect the speed at which objects fall, such as feathers? Obviously, it is more affected than the iron ball, so it falls more slowly."

Bai Dong looked at Aristotle with a smile, he used more heuristic education than direct argumentation for a smart person like Aristotle, because the person in front of him was a famous sage, and his stubbornness was also famous.

"Are you saying that without the influence of air resistance and wind, feathers would fall at the same speed as iron balls?"

Aristotle looked at Bai Dong seriously, and suddenly laughed out loud: "Hahaha, I didn't expect that the dignified Huaxia Baizi would say such unfounded words." This is an experiment that simply cannot be done. Unless you can find a place. There is no air and no wind in this place! But can you find it? ”

"I could, there must be such a place nine days away, but we can't get there."

"Doesn't that mean you didn't say it?" A hint of disdain flashed in Aristotle's eyes.

"Just because I can't find a place like this doesn't mean I can't do such an experiment. The influence of air resistance and wind cannot be eliminated, but we can find qualified test subjects, such as two iron balls with the same volume and shape but different weights, which are not as sensitive as feathers, and can basically ignore the effects of air resistance and wind. If they could be implemented at the same time, would it prove that Mr. Aristotle's theory was wrong? ”

"If you can do it, I'll admit that my theory is wrong! Do this experiment now! ”

Aristotle jumped up, he really couldn't wait any longer, since he met this Chinese white son, he seemed to have become an idiot, he must end this experience as soon as possible, otherwise it will affect his mood for study!

"Mr. Aristotle doesn't have to be in such a hurry, I have to make some preparations to complete this experiment."

Bai Dong chuckled. To completely subdue a sage like Aristotle, you must first break through his psychological defenses. Starting with the theory he is most proud of is the quickest way to do it. I'm sorry, Mr. Aristotle, but you are a great scholar, and I am only pointing out your fallacy two thousand years in advance

***

For a scholar who is anxious to verify the truth, it is a sin to wait.

Aristotle stayed awake all night, if it weren't for Bai Dong's close guards to stop him, he would have rushed into Bai Dong's room at night, and then asked Bai Dong if he needed to divide day and night into experiments? Can the two iron balls you mentioned be completed tomorrow? The place where the iron ball is thrown must be high enough, otherwise the results of the experiment will not be convincing

In Aristotle's fragmented thoughts, Bai Dong slept very soundly this night, cleaned his face in the morning, pushed open the door and took a deep breath of fresh air with the smell of the sea, and then saw Aristotle with a pair of panda eyes.

"Hey, Mr. Aristotle, did you sleep well yesterday?"

Ying Si trotted in front of Bai Dong and offered his hospitality like a dog's leg: "Taifu, I ordered someone to prepare breakfast, with fragrant rice porridge and side dishes brought by our Lao Qin. ”

Aristotle glared at Ying Si viciously, this kid is so annoying, at this moment when he is about to verify the truth, he has not forgotten to eat!

However, the rice porridge and side dishes in Huaxia are really delicious, Aristotle actually drank two bowls in a row, and then anxiously urged Bai Dong to complete this experiment that kept him awake all night, he must win back this game, and he must not lose the face of Plato's Academy.

"Mr. Aristotle, please see, that watchtower is the place of our experiments, let's go over now, if nothing else, the two iron balls have been cast."

Bai Dong pointed to the highest watchtower in the military port, and at this moment the tower was surrounded by hundreds of soldiers, even Pang Juan had arrived.

Hearing that Bai Dong was going to make a bet with this scholar from Greece to do an experiment, Pang Juan was also very interested, but he was not optimistic about Bai Dong, fools know that heavy objects will fall to the ground first, so what kind of 'experiment' do you need to do? He specialized in military research in Guigu back then, but he had never studied Gewuxue, and he would not blindly worship Bai Dong like Ying Si.

Under the guidance of Bai Dong, Aristotle walked to a long wooden table, on which were placed two iron balls of the same volume and shape, Bai Dong asked the craftsman in charge of casting the iron balls a few words, and then explained to Aristotle with a smile: "Mr. Aristotle, the ball on your left is made of pure iron and weighs five Chinese catties, while the iron ball on your right is hollow, and red gold is injected into the gap, so its weight is ten Chinese catties, for the sake of fairness, you can try the weight." ”

Aristotle nodded, picked up the two iron balls and tried to weigh them, and as Bai Dong said, the iron ball on the right was twice as heavy as the one on the left.

After Aristotle checked the iron balls, Pang Juan also came over and hugged the two iron balls respectively, and then looked at Bai Dong with great doubts, he couldn't understand if his junior brother was crazy, and he knew that the gambling game he was going to lose would continue?

Bai Dong smiled at him: "Just trouble the general to bring these two iron balls to the watchtower, and then throw them down at the same time, Mr. Aristotle, this is my general of the Qin State, he is the only one who walks up to the tower, and it is impossible for him to hide the same iron ball on his body, is this fair?" ”

Seeing that Aristotle did not object, Bai Dong smiled and said, "Then it will be troublesome senior brother." ”

"It's not troublesome, it's just that you lost, it's a pity, my reputation as a ghost valley gate"

Pang Juan sighed, quite unwilling to walk up to the watchtower, he devoted himself to military affairs in his life, Wei gave him the opportunity to lead the army to fight, he was loyal to Wei, Qin gave him the opportunity to lead the army, he was loyal to Qin, if you say that there is a home in your heart, that is, Qingxi Guigu and the teacher who has not been seen for many years.

So it doesn't matter if Bai Dong wins or loses, but hurting the reputation of the Guigu Gate makes him a little dissatisfied; However, this little junior brother is a strange elf, maybe there are some hidden means, otherwise he will definitely refuse to help Bai Dong do this experiment.
