"Looks like I need to do another experiment for you." Zhang You said with a smile, and said to Xu Guangqi with a ready-made lit candle: "Do you smoke?" Here, order a pot. ”

Xu Guangqi had a cigarette pot on his body, and when he heard this, he suspiciously took out a bag of cigarettes, lit a candle, took a deep breath, and raised his eyes to look at Zhang You.

Zhang You took the smoking pot with green smoke in his hand, and Nunu said, "See the smoke, right?" ”

Everyone nodded, their expressions becoming more and more suspicious, and they really couldn't guess what kind of medicine was sold in his gourd.

"If there is no external force, the smoke will be vertically upward, now you see." As he spoke, he slowly moved the smoke pot two or three inches away from the candle, and under the influence of the rising hot air, the smoke that had been vertically upward turned a corner, drifted diagonally towards the candle flame, and then floated upwards in the direction of the candle flame.

This kind of phenomenon is actually very common, Xu Wei didn't know why, and said with some disdain: "What does this mean?" ”

"I think that's why the wind is formed, the hot gas will rise, and everyone should have no doubt about it, after the hot air rises, there will be cold air to replenish it, and then it will become hot, and it will rise, and when it is cold, it will fall, and it will be replenished, and so on, and so on, like drawing a big circle. I call this phenomenon air convection. Recognizing this phenomenon helps to understand why there is no thunder in winter.

Quite simply, in winter, the temperature is low, the heat rises slowly, and the intensity of the cold air friction is not enough, so it is impossible to form charged clouds...... Well, I call the invisible substance that is generated by rubbing * rubbing "electricity", so far, I think this kind of electricity should be divided into two kinds, the silk rubbing * rubbing the glass rod, I call it 'positive electricity', and the fur rubbing rubber rod is called 'negative electricity', only when the positive and negative electricity meet, the phenomenon of discharge will occur, and sparks and sounds will occur, and this phenomenon will not occur when the same kind of encounter does not occur. ”

Speaking of this in one breath, Zhang You picked up the teacup and poured a few sips, not to mention, he was really thirsty.

Everyone was immersed in his unheard-of novel theories, and their brains were quick to understand and be convinced, such as Er Zhao and Xu Guangqi, who were young, had no qualitative thinking, and were quick to accept new things and new ideas. Guo Zaoqing was a little worse, frowning and pondering, as for Xu Wei, he felt that this set was really a bit open-mouthed, and he had the heart to refute it, but he really couldn't find an explanation.

"Well, whether you're right or not, I just want to ask you, what does all this have to do with instant messaging?" In the end, he decided to avoid the important and not attack Zhang You's theory, but moved on to the original topic.

This is indeed his doubt, to be honest, Zhang You's theory does sound quite novel, but he feels that there is no point in researching, and what he cares about most is the instant messaging.

Immersed in the joy of discovering a new theory, Xu Guangqi and the others even forgot their original intentions, and only then did they react when they heard the words: "Yes, my lord, didn't we talk about instant messaging, how did you talk about this?" There should be a relationship between the two, right? It's a pity that the lower officials are stupid......"

"I'm just thinking about a question," Zhang You interrupted Xu Guangqi, his hand did not stop, and connected the two terminals of the potato battery pack to a long copper wire, and then said: "There is no doubt that potatoes generate electricity, as for whether it generates positive or negative electricity, it depends on whether it is a copper plate or an iron plate inserted into it." Now, I've connected about four or five meters of copper wire to each end, and now, if I put the two next to each other, do you think there will be a discharge? ”

As he spoke, he didn't give everyone a chance to react, and quickly leaned the two ports of the connector together, without any suspense, the spark flashed again, and there was a crackling sound at the same time.

"Okay, now let's expand the association, what if the lines are longer? Fifty meters, 500 meters, or even 5,000 meters, will this phenomenon happen? ”

Zhao Zhenyu raised his eyebrows: "I understand what the adults mean, if the adult's idea can be established, only need to set up a switch at one end of this distance, you can control the discharge phenomenon at the other end......" Speaking of this, he suddenly stopped, got up and paced back and forth a few steps, and then stopped and said: "There is a spark, there is no spark, and then there is a spark, and then the control switch can at least cause these three phenomena, and then you get three symbols, there is, no, long, and then follow this line of thought, you can get again: there is none, there is no long, There is no long, there is no long, there is no long, there is no long...... My mind was a bit confused, and I couldn't count how many combinations there were, and each combination could correspond to a symbol...... It's just that we have so many Chinese characters, it seems that we still can't solve it......"

He paused again, deep in thought.

The rest of the people followed his train of thought, and they also fell into contemplation with an excited mentality, this time even Xu Wei was no exception, and he suddenly found that if Zhang You's hypothesis could be true, there was suddenly hope for instant messaging that Shi Cai still felt nonsense.

The wisdom of human beings is really unfathomable, Zhang You was moved, he actually can't remember the specific process of the invention of the telegraph, but he knows that the earliest invention of the telegraph was built after the discovery of such a thing as "electricity" by human beings, so he gave you an experiment with the attitude of giving it a try and explained the knowledge that is very basic for later generations.

Zhao Zhenyu's words suddenly reminded him that the invention of the telegraph seemed to be based on the principle that Zhao Zhenyu said, and a foreigner created a set of far-reaching Morse codes.

This Zhao Zhenyu is really a talent, drawing inferences from one another, it is really the luck of Daming that he was not hanged at the beginning.

He secretly sighed, and was about to mention them, when Xu Guangqi and Guo Zaoqing suddenly looked at him at the same time.

"My lord, do you remember that you seem to be able to speak English?"

"Zicheng, I remember Mary once said that the script of their country is made up of twenty-six basic letters?"

The two spoke at the same time, and then Zhao Zhenyu's eyes suddenly lit up, and he stroked his palms and said: "Yes, why didn't I think of it, I just need to find a way to make twenty-six combinations, and then someone understands English, won't this problem be solved, Lord Guo, Zixian, or you two are smart." ”

"Where, where, if you didn't come up with the setting switch first, what would it be if I and I came up with these first?"

"Yes, if you want to be smart, you have to be it."

Zhang You was both happy and helpless, and originally wanted to hang up for himself again, but people came up with it themselves, and they complimented each other, and they couldn't pretend to be forced if they wanted to.

"This problem is solved, and the next step is the most important part, don't forget, the methods we come up with now must have a foundation, and only Lord Zhang's idea can be realized." Zhao Shizhen's words brought the happy crowd back to reality.

Xu Wei said: "Yes, although the method is wonderful, how far this electric energy travels, and how fast it is still unknown, so ah, I advise everyone, or don't be happy too early, the greater the hope of the province, the greater the disappointment in the future." ”
