The twelfth year of Yuan Heng.

On the Liaodong side, Li Zhi also sent people to start according to Li Chong's plan to complete the search for warm currents and the determination of dimensions step by step.

In fact, it would be nice if you could make a clock.

Because if you can make a clock, by observing the time of the sun in the middle of the sky in the two places, you can probably determine the longitude of the person at this time.

dimension, mainly by stargazing.

This is also the reason why there is often an alarm clock on TV and movies, such as on a pirate ship or on a ship of officers and soldiers.

If you can get your own latitude and longitude, then no matter how vast the sea looks, the people on the ship will not be afraid at all.

At least......

They will be able to know where they are at the moment.

Even......

You can also calculate how long you have before you get to where you want to be.

All I can say is......

Li Chong's dean of the Academy of Sciences is worthy of being the president of the Academy of Sciences, if it were someone else, he would definitely not have thought of such a crazy idea.

The only problem now is that this direction is there.

But no one seems to have come up with a solution.

Especially this clock.

Divide the day into twenty-four hours, and then each hour is sixty minutes, and each minute is sixty seconds.

Let's be honest......

Even if they don't know the concept of hours, minutes, and seconds, it's not difficult to understand.

The hard part is that this thing is definitely made out of gears.

But how to design this gear.

Then let it move on its own.

It should be said that the difficulty is no easier than when designing a steam locomotive.

Li Chong drew a picture of a clock for them.

The numbers 12, 3, 6, and 9 are marked, as well as the hour, minute, and second hands.

The question is......

They can't just look at these superficial things.

It would be nice if you could draw how to do it inside!

If Li Chunfeng is still alive now, maybe with his strength, he will be able to do it.

It's a pity......

Li Chunfeng had already left them.

But don't be discouraged, anyway, Datang has talents.

As a result, after a year, my hair was almost bald, but Li Zhi still didn't do a good job here, so I had to see if there were any smart people on Datang's side in the Science Newspaper.

Science Newspaper is now a very important reading material in Datang, you can not read the book, but you can't help but read this newspaper.

On this day......

Li Chong got up early in the morning, drank white porridge, and read the newspaper at the same time.

Boy!

He asked Li Zhi to think about the problem, but as a result, Li Zhi returned and let the people on the Tang side think about it.

In fact......

It's not that he hasn't seen the internal structure of a clock at all.

Since Liaodong has been thinking about it for a year, but he can't think of it, then I'd better give them a little more hints.

Subsequently......

So he asked Xincheng to bring him a pen and paper.

Followed by......

Li Chong began to write and draw.

In the clock, in fact, the most important ones are the two mechanisms.

One of them, rolled into a bubblegum-like energy storage mechanism, is used as a power source for the clock.

The other is an escapement that allows the clock to move at a certain frequency.

As for the rest......

It's a question of how to control the number of turns for gears.

This question should not be difficult for them.

Of course!

Li Chong knows that there are two things, but how are these two things connected, cough!

It can only be said that the question ......

After all, he is not a professional clock repairer, and it is already very good for him to know that there is a yellow bullet and an escapement.

He didn't know how to take a look at it from the Internet.

I know that there is such a principle, there is such a thing.

That's probably the benefit of growing up in the 21st century.

In the era of information explosion, everyone can know things and know a wide range of things, but if you say that you are very professional and very refined, I am afraid that this is a bit difficult.

"And then ......"

Li Chong drank white porridge while trying to restore these two things.

Don't say it, Li Zhong still has some talent in mechanics.

With the way of thinking backwards, slowly, slowly, Li Chong seemed to have found a trace of feeling.

The so-called escapement mechanism is actually like a claw with two tentacles, which swings left and right, up and down, and then lets a gear move according to a certain law, and when the gear rotates, it must be stuck in order to move to the next tooth.

This is where the so-called grappling comes from.

Then, as long as he can restore this kind of left-right, left-right, one-on-one movement, then this mechanism should be able to be made.

If you think about it, you will continue to do it in this direction.

When the porridge was almost cold, during which he had to feed himself in Xincheng, Li Chong finally drew this thing.

As soon as this picture came out, although it was not said that 100% of the work was completed, no matter how it was, it could be regarded as at least half completed.

I'm a genius!

As soon as I was happy, I was also ravaged by holding the new city, so I happily asked people to send it to Liaodong.

Li Zhi's side......

It took less than ten days to receive the letter.

Otherwise, Li Chong is the dean of the Academy of Sciences, and it feels like nothing in this world can be difficult for him.

Of course!

Li Zhi is also very curious, since you know what to do, why don't you bring it up early in the morning.

Li Chong can only say......

That's how he is, he will only do something when he is interested, just like his homework will only be completed when he is almost back to school.

The craftsmen of Liaodong learned that there was such an institution.

And it was also done, and it was tried.

It worked, and I moved on to the next step.

Although this escapement has been made, they still have a lot of work to do.

For example......

How big this clock should be, as well as this lubrication, as well as accuracy.

These are all questions that they have to consider.

That is, it took about three months for this clock to finally have a qualitative breakthrough, and now, this clock has basically taken shape.

At this time, the ratio of the hand, minute hand, and second has also been set by them.

Of course!

Some people will definitely have questions, why is it 3,600 seconds, eh......

What to say about this question.

That's not easy to explain.

Anyway......

As long as it works.

It is regarded as a conventional rule, and the reason why it is divided into 3,600 seconds must be because such a gear ratio is easy to do.

In terms of clocks and latitudes, there are also special stargazers who use astronomical means to solve them, and now, there is basically no problem with positioning.

Next, it's up to the ships delivered in Yangzhou.
