Three Kingdoms: I, Liu Adou, don’t need anyone to support me

For the confirmation of measurement, Huang Yueying felt that her knowledge was suddenly lacking, because measurement is something that has been used from the ancestors to this day. She couldn't overturn these things now.

However, isn't there still Liu Chan!

Since he can put forward such an idea, he must have a certain understanding of this kind of thing. Therefore, it is better to find Liu Chan for this matter.

So, Huang Yueying applied to enter the palace, and then met Liu Chan.

After Liu Chan heard about Huang Yueying's matter, he then pondered: "Actually, measuring this kind of thing is not something that can be formulated at will, but must be accurate enough. Now the smallest unit we use on a daily basis is one inch. But under an inch, how to distinguish it? So, make the tolerance of this unit of measurement smaller! Let's divide this inch into three points and three equal parts, and the life is one centimeter. A centimeter is divided into deciles, which is one millimeter. A millimeter is divided into decimal fractions, for one micron, and one micron is divided into decimal fractions, for one nanometer..."

When Liu Chan was distinguishing the scales, Huang Yueying on the side was full of shock.

An inch is divided into three, which is a very small measure.

And he not only divides it into three, but also makes it constantly distinguish downward, such as the millimeter, which may be visible to the naked eye. But what about a micron, can a person see clearly?

However, she didn't bother Liu Chan out of the loud, but listened to him continue: "After that, there are actually units of measurement, but I'm afraid that after a hundred years, we won't be able to find out." And upward, ten centimeters is a decimeter, then a meter, and then a kilometer. Isn't it okay to divide it like this? "

"But first, you have to make an extremely accurate original. Take the gear on your drive shaft, the error should be placed in the micron level, and at most less than 50, so that you can be sure that the gear accuracy on the gear is about 100. There is one more thing to do in this matter. You come with me, I'll show you what the microcosm is.! "

"Microcosm?"

Huang Yueying looked at Liu Chan in a daze, not understanding what kind of new word this was.

For Huang Yueying's reaction, Liu Chan has long been used to it.

He didn't explain, but took Huang Yueying into a room on the side.

Then, he polished himself and handed over the simple microscope he had made: "This is a microscope, you can see very small things. However, only some things can be magnified by about fifty times. You pluck a strand of hair and put it in the middle area to see. "

Huang Yueying plucked out a strand of hair according to Liu Chan's idea, and then carefully placed it in the center of the bottom.

When she saw through the microscope that his hair was magnified a lot, her heart was very different.

Moreover, she also saw that her hair was not a cylinder, and some parts were missing.

And this missing part is something that she can't see with the naked eye.

Seeing this, she seemed to have opened up a new world.

Just as she was about to speak, Liu Chan took out an extremely clear cup of tea and handed it to Huang Yueying.

"Do you think this cup of tea is clear?"

Huang Yueying nodded.

However, Liu Chan said: "You look carefully and see clearly, are there any other impurities?" "

Huang Yueying looked at it carefully this time, and then nodded and said, "It's very clear." "

Liu Chan smiled, and then he dipped a drop of tea with chopsticks, and then put it under the lens for Huang Yueying to continue watching.

At this look, Huang Yueying was shocked.

The tea looks clear, but in fact, there are many tiny items that cannot be seen by the naked eye. She looked up at Liu Chan and asked, "Your Majesty, this... This thing is so amazing, can you give it to me so that I can go back and study it? "

"It's good, this thing is very helpful to you. However, just one is obviously not enough. You can take the person who polished the microscope with you in an instant. He'll show you how to make it. However, you have to be careful about measuring, and you have to make a standard. What you can see every day is a meter, a decimeter, and a centimeter. You make these things, and then you polish the gears, and it's going to be a little bit more accurate. By the way, now that you've started the experimental phase, it's proven that this thing is almost complete, and you just need to improve it later. Now, I'll give you something else. That is, to use this liquid, for the combustible..."

Liu Chan said as he lit the extracted pure lamp oil and said, "This thing, after burning, will produce a lot of heat and gas. The principle is the same as water vapor, but when burned, it is in a confined space. Unlike the engines you're working on now, you need to constantly add firewood, or charcoal. Here's the principle and some drawings, so you guys should study it. "

After more than a year of searching, I have found an oil reservoir in Longxi. (Read violent novels, just go to Feilu Fiction Network!) ）

This kind of oil cannot be burned easily.

However, it is possible to distill this kind of thing. Depending on the temperature, many different substances are extracted.

Liu Chan didn't know about this thing, but he could send someone to experiment.

He has been in this era for so long, and he feels that the people of this era are actually not stupid, but in this era, they mainly study the Four Books and the Five Classics, and other skilled craftsmen have no status. That's why the development of science and technology is so slow.

But since he has begun to distinguish between these things, he will naturally not continue to study in this way.

Now, if you tell them how it works, they will have a lot of ideas.

Therefore, although it is very difficult to completely realize industrialization, Liu Chan believes that if the country supports it, it will only take 50 years to cross the initial level of industry.

Moreover, the usefulness of this microscope is not limited to industry, life science, medicine, and even biological evolution.

Only by completely opening up the microcosm and letting ordinary people see this. They will pursue more knowledge.

But Liu Chan found that he stuffed so many things from his previous life into the society at one time, can these people accept it?

But he can't take care of so much now, because if he doesn't do this, then many technologies will not be developed in a short time.

Like the existence of railroad tracks?

Now he lays the railroad tracks, all of which are made of wood.

First, it can be made from local materials, and second, it doesn't need to be transported too long distances.

It's convenient, and it's affordable.

Moreover, it can greatly improve efficiency!
