As soon as I have knowledge that I can t see, or I can t remember where I saw it, I worry about what

Relax your mind and don't put too much pressure on yourself. If your emotions continue like this, it will also have a certain impact on your own physical health.

Sometimes, for example, when I read the newspaper, I think there is a passage that is particularly useful to me, but there are always various reasons at the time, and anyway, I just didn't write it down, and when I think about it later, I can't find it. I don't know what your job is, but if there is something that is relevant to your work, then you need to develop good work habits, such as sorting all the newspapers and magazines into categories, or cutting out useful ones. It's hard to put it in a special notebook and develop a good study habit, but if you think that you can do your job better and your boss will recognize you, then you can do it.

However, if this is just a hobby of yours and has nothing to do with your work, I advise you not to put too much pressure on yourself, the most important thing in a person's life is to be happy, and everything else is secondary.

In addition, you don't have to copy down the knowledge you said about what you saw on the Internet, you can copy it first, and then paste it into a document or a clipboard. Isn't that okay!

You go look online.

This sense of déjà vu has been discussed in the psychology community for a long time.

20 things that happen in one minute.

Every year, thousands of fortuitous events occur, and data is collected by researchers, scientists, and analysts. These numbers appear frequently – too large to be explained, but they are significant. To prove the "power" of some of these figures, here are 20 scaled-down estimates.

Lu You died and knew that everything was empty, but he was sad and did not see Kyushu.

Wang Shi set the Central Plains Day in the north, and the family sacrifice did not forget to tell Naiweng.

I knew that when a person died, there would be nothing. It's just sad that I didn't see the reunification of China with my own eyes. On the day when the imperial army regained the northern territories, do not forget to tell your father when you worship your ancestors at home.

1, Plane reflection and diffuse reflection, 2, Mirror refraction occurs, while ground glass is opaque and does not undergo refraction. 3. Imaging principle, mirror can be imaged, but ground glass cannot.

Specular reflection occurs in mirror glass; Ground glass is diffusely reflected.

Because the ground glass scatters the light, just like the reflection in the water is scattered!

Because ground glass is diffusely reflective.

You first see if you open the web page properly.

It is recommended that it is best to kill the poison first. If otherwise normal.

Uninstall this QQ first.,Then go to the QQ official to re-create a new one and install it.。

In fact, the knowledge you have learned is the result of the summing up of the predecessors in scientific practice, let us learn, you have learned, I have learned, there is no such thing as your knowledge being sucked away. We must all learn knowledge well and apply it to our scientific experiments and production practices, so as to produce more results and avoid detours.

The average person's lifetime use of the brain is only a few percent of the brain cells, and Einstein is only about 10 percent, and even if you memorize all the dictionaries, you can't fit your head.

You will forget something, and your fears and anxieties will increase, as the so-called "ignorant are fearless".

It is said that the human brain can hold the world's books, so it should not be mixed.

You're so studious, how cute! The brain volume of the family is very large, and there will be no problem.

The potential of the human brain is limitless relative to the exploitation of human beings today.

Even people who memorize dictionaries use less than 1% of their brain's storage at most.

So don't worry at all.

The mechanism is different.,It's not going to crash.,But it looks like a neurosis.。

When the human brain dies, the person will almost say goodbye.

Ahh

You see Einstein is fine, cold. Even if someone with too much knowledge suddenly falls ill, this is a pure accident.

If you feel like you have too much knowledge, you can chop off some of your heads! Ha ha.

I don't think so. At best, I forgot what I had learned.

The surface of ground glass is rough, and when the light is illuminated, a large amount is reflected, and a small amount is transmitted into it, but the second exit is a large number of reflections, so there is no light to reach the target object, and there is no light reflection to your eyes, so you can't see it. You can try to draw a simple diagram to illustrate, that would be more intuitive...

The basic thing upstairs says is correct, but the word refraction is used incorrectly, it should be reflection.

Because the surface of frosted glass is uneven, light does not pass through parallel when passing through the glass, but is refracted in all directions, so the object behind the ground glass is not visible.
