Chapter 555: Making a telescope

In order to master the astronomical calendar, ancient China spared no effort to establish a special agency "Imperial Heaven Supervision" to observe the astronomical phenomena and write the calendar.

Telescope inventions, like most technological discoveries, were done unintentionally.

In the early 17th century, in order to check the quality of the grinded lenses, the owner of an eyeglass shop in a Dutch town lined a convex lens and a concave lens in a straight line. Looking through the lens, he was surprised to find that the spire of the church in the distance became larger and closer, and the secret of the telescope was revealed to the world.

Of course, the owner of this glasses shop is very smart and he applied for a patent.

Although there is patent protection, the development of telescopes cannot be prevented, because great scientist Galileo also joined the ranks of telescope production, and the telescopes developed are beyond the reach of the owner of the glasses shop.

Galileo used telescopes to conduct astronomy research and achieved fruitful results.

There are many famous telescopes in history, such as the Hubble Telescope, which are almost household names.

Different uses, the method of making telescopes is different. Of course, Li Yuanba would not be too ambitious and pursue such unattainable telescopes just to make telescopes that are almost the same as in our modern life.

Even if the quality is not as good as that of modern telescopes, it is much better than using flagstones. It is more powerful to observe the battle situation with the naked eye.

Telescopes are ultimately a problem of lens application. Can it be stumped by military monitoring if they have to be lenses?

When Li Yuanba asked, Ye Wanqing and the others laughed and pointed at Li Yuanba, "Your Highness, you are really scary. This thing is too simple, and this mold is easy to make."

It's really simple to say that lenses are really simple.

It's not difficult.

But.

With a lens.

With a telescope.

This has a very big impact.

Li Yuanba said seriously: "Master Ye.

Just talk about clairvoyance.

It's really simple.

Very easy to do.

Our military weapon supervisor will definitely do it.

but.

Do you know what the impact will be?"

"Isn't this...just see further and more clearly?

You can see clearly even from ten miles away."

Kou Yibing didn't know that the telescope that Li Yuanba said was just a drop of water in the sea.

Not at all concerned.

Li Yuanba thought to take advantage of their interest to explain the use of the telescope clearly.

Give them a clearer understanding.

After thinking for a moment, he said, "Master Kou.

You're right.

But not completely.

The use of clairvoyance is far more than these.

I want to.

If we create clairvoyance.

Give one to each general.

You want to.

They commanded the war.

Is it still so laborious?

How is the battle?

Just look at it and you will know..."

The words behind Ye Wanqing were interrupted: "Your Highness the Crown Prince."

This makes sense.

Can see ten miles away.

Generally, small-scale battles are clear at a glance.

only.

A battle dialect.

That's not enough."

The battlefield varies according to the terrain and target.

Even if the same number of troops start fighting.

It may not be a battlefield of the same size.

The Battle of Changping.

The entire battlefield runs for hundreds of miles.

The entire Shangdang area is a battlefield.

That's because it's mountainous.

The terrain is complex.

The Qin army is of the same number as the Zhao army.

Bai Qi could only use complex terrain to encircle the Zhao army.

Liang Shizhan fought.

After the Tang army crossed the Nujiang River.

There was no further progress.

One reason is that the landlord Dezuzan is right in front of you.

He must be defeated to advance.

Another reason.

It is a plain area with dozens of miles in radius on the south bank of Nujiang River.

It is suitable for large legion combat.

It's a good battlefield.

Therefore, the Tang army stopped here.

No further progress.

Kou Yibing smiled and said, "It's enough to be able to see ten miles."

Li Yuanba continued: "Types can be used in military affairs, but they are also very useful for our military weapon monitoring.

Master Ye, do you know what the world you live in is like?”

"This..." Ye Wanqing stopped asking, and was stunned for a while before saying, "What's there to ask about this?

There is food and drink, there is wind and sunshine."

Li Yuanba shook his head and said, "Master Ye, the world you live in is a world of dust. If you have a microscope with enough multiples, you can clearly see how terrible the environment you are in, and countless dusts wrap you.

A microscope is another way to use a look glass.”

Some people were so frustrated because they saw the environment they were in clearly that they were in. When I was in elementary school, a few classmates were like this, so worried that they couldn't even eat.

"No way?

dust?

Why can’t we see it?”

This is a fact, but Ye Wanqing and the others still don’t believe it.

"That's because our eyes cannot see it, and we can see it with a telescope."

Li Yuanba said with great certainty: "Even the water I drink contains countless insects.

Why is drinking raw water easy to make people sick, but drinking boiled water is fine?

This is the reason.”

"There are insects in the water?"
