In fact, even if Zhao Wei has a little optical foundation, he will know that not only did Zhao Youqin's telescope not make any mistakes, but the principles of the microscope are actually not that complicated.

The telescope used in later generations is indeed a combination of a convex lens and a concave lens. The principle is that the image of an object is focused through the convex lens, and then scattered into the human eye by the concave lens.

The scientific name of this telescope is Galileo Telescope.

Zhao Youqin's combination of two convex lenses can also serve as the purpose of a telescope. The principle is that the distance between the two convex lenses becomes longer. After the light is gathered through the first convex lens, it is scattered to the focus in the lens barrel and then scatters towards the second convex lens.

Because of the upside down light, the images you see after entering the eyes are reversed.

This is called the Kepler Telescope, and this is the monocular telescope of the Age of Discovery.

So the question is, Zhao Youqin's direction is not wrong, but why didn't he get the Kepler telescope?

Haha, because Comrade Lao Zhao put the two lenses in reverse.

If Zhao Wei or Zhao Youqin is not imprisoned by the single tube with a large head, he naturally thinks that he should look from the small head to the big head.

Anyone who has touched it has no hands, mischievously looks from the big head to the little head.

If Zhao Wei goes to junior high school for a few more days, he will not let Comrade Zhao almost bald in order to polish out a concave lens.

But it is precisely because Zhao Youqin installed two convex lenses with different refractive indexes in reverse that he got another combination of biconvex lenses - microscope!

Some things are so wonderful, with the pain of not getting what you want to plant flowers with your heart, and the blessing of planting willows without your heart.

Zhao Wei asked for a telescope to fight, but he found a microscope.

Not to mention, I was swearing to Old John the other second, "Microscope? Impossible!"

But the next second, Zhao Youqin entered the door with a microscope in his arms.

You said this is a coincidence?

No, Zhao Wei thinks, God is opening his eyes.

Don't underestimate such a thing that seems to be less practical than telescopes and has no major applications in this era.

It is hailed as one of the greatest inventions of scientific and technological development, and it is not unreasonable.

It can be applied to almost all fields and is a basic tool for almost all disciplines.

With it, John Old can really start studying blood types and then achieve blood transfusion.

With it, Wang Sheng can see microorganisms. Even if he can't see bacteria, he can fundamentally understand why surgery requires disinfection.

With it, Huang Daopo can directly observe the subtle structure of onshore cotton and improve textile technology.

With it, you can even see how many parasites are in the water, how wonderful it is in the teeth, and how many mites are on the face, which will change the drinking water and hygiene habits of this era.

With it, chemical talents like Liu Derou, and even blacksmiths, can directly see the microstructure of matter. At least you can know what the use of shark bones are, and you can also see why good steel is good from the structural arrangement of steel.

In the past few years since Zhao Wei came to the Song Dynasty, he realized the simplest truth:

The ancients never lacked wisdom and creativity. What they lacked was the way to understand the world and a broader vision.

Telescopes and microscopes, one can make people look up at the starry sky, and while knowing the universe, they can also wake up from the smallness.

The other is that people can bow their heads and explore the essence of this world and the origin of life.

And now, there is a microscope!

It's just a little regretful, can't you look up with your head facing up?
