# Shock your eyes: what do you see when your skin magnifies 100 million times

We always think that our eyes can see any matter or object in the world, so some people have a stubborn idea that what they see through their eyes is real; what they can't see is not believed. Don't believe it if you can't see it. It sounds reasonable, but at a slightly higher level, it doesn't.

The development of modern science has confirmed this. Please see under the microscope to enlarge the human hand a little by 1-1016 (power) times. What can we see? Super shock!

1 meter

Wake up! I don't know if you've been peeped.

0.1M

One tenth of a meter, also called decimeter, is the scale that our hands can grasp. It is believed that most of the objects touched by human beings are in such an order of magnitude. Look around you, keyboard, mouse, mobile phone, cup, bowl & hellip; & hellip;

Take a closer look at this guy's hair. It's quite heavy, pure man!

1 cm

This is the detail of the wrinkles on his hand. Maybe you've magnified it, but you haven't seen him yet. We are ready to enter another unfamiliar field, the micro world.

1 mm

Pores in hands. But what about the hair? Dizzy!

100 microns

Ten times larger, the tissue structure of the skin can be seen vaguely.

10 microns

A cell's order of magnitude is 10 microns, which is just general. In a word, the biggest cell in the world is ostrich egg. It's a single egg cell. The order of magnitude is decimeter. It's powerful.

1 micron

It's suspected that the cell nuclear membrane of biology class.

0.1 micron

Hey! Look at the structure of such a high helix, it's a chromosome. According to the following foreign language, there are 23 pairs of chromosomes (46) in every human cell.

100 a

Angstrom is a unit of length, which means 10 to 10 meters. It is indicated by a small circle at the top of the letter 'a'. The order of 100 Angstroms can measure some organic macromolecular substances.

Seeing the equidistant double helix structure of this rule, I think you can blurt it out. Yes, this substance is called DNA, which is often called DNA. The molecular structure is clearly visible.

1nm

We call 10-9 square meters one nanometer. Now, nanotechnology, which is hot for material science, means that many materials will show many properties that cannot be shown in the conventional order of magnitude when they are refined to the nanometer level. In the order of nanometers, we can even count the atoms. Therefore, the nanometer level is also called the atomic level.

Here are the atoms that make up the DNA molecules, which combine with each other in covalent and hydrogen bonds to form large organic molecules. Life is embodied in this complex combination. Salute!

1 angstrom

You should know from middle school that atoms are made up of nuclei and electrons. The picture below shows a dense electron cloud. We can see that the electron cloud around the nucleus is relatively thick.

The so-called electron cloud, in fact, does not mean that an atom has innumerable electrons, which is like a cloud. Each atom has a fixed number of electrons, depending on the type of element. These electrons move in and out of the nucleus. One electron, countless Dharma bodies. We use the electronic cloud to describe the characteristics of these electrons. Closer to the core, the cloud is denser; closer to the core, the cloud is rarer.

10 PI meters

A dense cloud of electrons around the nucleus. As if to the boundless universe. In this way, every atom is like a small universe, and our world is like this, shivering & hellip; & hellip;

1 PIMI

Through the thickest electron cloud, it is found that the area closer to the nucleus is clean. It turns out that if you want to attract people when you are far away from them, you will also repel them when you are close to them. It's better to keep the best distance. (it's kind of like dating^_ ^

What? You say that the electron is negative, the nucleus is positive, and the opposite sex is attracted. The closer the nucleus is, the denser it is? Don't tease! The closer it is, the more it is attracted, the closer it is, and the electrons don't all hit the nucleus. At last, no one can move!

But why not? National secret! The spot in the box below is the nucleus.

0.1 PIMI

Come closer, this is the legendary nuclear. Ten to twelve square meters is called a PI meter. In the order of 0.1 PI meters, many spheres can be seen from the nucleus. They are positively charged protons and uncharged neutrons.

10 flying meters

Close up of the nucleus.

1 flying meter (10 to 15 square meters)

The details of protons (or neutrons) are a mess. Unknown structure, unknown domain

0.1 flying meter

The foreign language below the picture says: once we enter the next level, what will we see and what will we know? & hellip; & hellip;
