Chapter 145 Searching for Substances That Change the World (seeking subscription, first more)

There are many kinds of substances, but weird ones. Chen Fan's selection of big data comes from the natural world. What he chooses is actually some unsolved mysteries of the natural world.

In other words, it is actually a series of simple things.

But 80% of strange things are actually related to magnetic fields.

In physics writing, the magnetic field is simply taken out as the content of the explanation.

Putting it on, Chen Fan looked at the drawing and said, "I think, what you want is for people to walk in, and there will be no accidents, and they will be able to come out, right?"

Everyone nodded one after another.

The people in a boat need to be rescued.

Chen Fan thought for a while and said: "This is not difficult. In fact, as long as we ourselves have a huge magnetic field and form a cycle of the earth, we can walk."

"

How can this be done? It requires a lot of materials and energy..."

Everyone's words are general, and it stops, there is no shortage of materials, and no shortage of energy. Then, this can almost be done theoretically.

A group of big guys gathered in the laboratory, and Zhang Dongshan said: "How to raise, this laboratory is still possible."

Chen Fan nodded and said, "Those people are Mensa members? How do you feel stupid?"

"It was originally stupid, normal, but, I think, these people actually have no need to exist, and in the end, these people will actually be replaced."

"Oh, okay, don't you understand well, will you help me?"

"Can."

Chen Fan nodded and began to write about the subject of the experiment.

Magnetic field detection.

1. Preview requirements

1. What is Faraday's law of electromagnetic induction? 2. What is an electric dipole?

3. Understand the basic structure and characteristics of wire antennas

2. The purpose of the experiment

1. Understand the time-varying electromagnetic field, understand the principle and function of electromagnetic induction

2. Understand the characteristics and basic structure of the antenna through the design of electromagnetic induction device 3. Understand the principle of electromagnetic wave radiation

Three, experimental principle

The time-varying electric field must generate a magnetic field in space, and similarly, the time-varying magnetic field also generates an electric field in space. Electric and magnetic fields form two inseparable parts of a unified electromagnetic field. The device that can radiate electromagnetic waves is called an antenna, and the power signal generator is used as the emission source to generate electromagnetic waves through the transmitting antenna. If another antenna is placed in an electromagnetic wave, a high-frequency current can be induced on the antenna body. We can call it a receiving antenna. The closer the receiving antenna is to the transmitting antenna, the stronger the electromagnetic wave power and the greater the induced electromotive force. If a low-power incandescent bulb is used to connect to the antenna feed point, the incandescent lamp can emit light when the energy is sufficient. The receiving antenna and the incandescent lamp constitute a complete electromagnetic induction device.

Looking at these things that Chen Fan finished writing, Zhang Dongshan said: "You are, a theoretical experiment of magnetic field?"

"Yes, in the theoretical experiment of magnetic field detection, I need to know whether there is a magnetic field in it, and there is another point, why a circle is formed. This is an elegant question in itself. Why hasn't this topic become a millennium? Difficult problem?"

"Because there is no way to divide it into academia, everyone subconsciously thinks that these are in fact fantasy, not science, because it is too bizarre, and everyone can't estimate whether pure time stops or not."

After thinking for a while, Chen Fan nodded. Zhang Dongshan was telling the truth. People don't move. In fact, the theory can be achieved. The human body freezing technology is completely possible.

But it's just relatively immobile.

Just as Newton's law said at the beginning, motionlessness is the core.

Most of them are relative.

Start to assemble the equipment and perform a simple evaluation.

The robot was put in.

The first time, it failed.

After the robot entered, the signal disappeared.

If time does not move, then light will actually be swallowed.

Because light itself is a kind of matter, as long as it is matter, it can actually stop.

"Why does the first photo exist?"

"Because when it was discovered, his formation was still a rough idea."

"You mean, even if we don't do anything, these people can actually come out, right?"

"Yes, if there are many such phenomena, it has been reported long ago, but I think it was not reported because it was just a short pause. People's thinking and five senses have been paused. Then, the pause is also a normal thing. , It’s just that when they stepped out, everyone forgot about these things, or they didn’t form a memory."

Brother, are you making a movie?

No one can accept what Chen Fan is talking about, or that these are just theoretical physical data.

There is a difference between theory and reality.

Chen Fan didn't give up, and continued his new experiment.

Half-wave antenna, also known as half-wave oscillator, is one of the simplest modes of symmetrical antennas. A symmetrical antenna (or symmetrical oscillator) can be regarded as formed by a two-wire transmission line with an open end. This type of antenna is one of the most common antenna types and is also called a dipole antenna. The half-wave antenna is the most widely used antenna among symmetrical antennas. It has the advantages of simple structure and convenient feeding. The half-wave oscillator is named after its arm length is λ/4 and the full length is half the wavelength. The radiation field can be obtained by adding the radiation fields of two single-line standing wave antennas, so the far field strength of the half-wave oscillator (L=λ/4) has the following relationship: │E│=[60Imcos(πcosθ/2) )]/R. sinθ

=[60Im/R. ]│f(θ)│In the formula, f(θ) is the direction function. , The normalized direction function of the symmetrical oscillator is│F(θ)│=│f(θ)│/fmax=|cos(πcosθ/2)/sinθ| where fmax is the maximum value of f(θ).

After writing a little bit, Chen Fan started to design the equipment in his hand.

Handle it and put it in.

The screen is transferred back.

Everyone looked at the world inside, unconsciously meditating.

A bird stopped in the air.

The ripples on the water also stopped.

It's like the earth is really pressed, the pause button.

Is this science?

"This world..."

Chen Fan said: "I think what I need is right here. This is the most perfect and most naturally occurring magnetic field."

"I suggest, save people, but keep the magnetic field itself."

"Or, wait for the disappearance of the magnetic field, and then complete countless experiments."

Everyone looked at each other, it was a bit unacceptable,

"Save people first, how to deal with this place, I'll talk about it later."

"Oh, what do you mean, does this need to be divided into areas shared by the world?"

A man said, "I think this area belongs to you, right?"

Chen Fan gave an occasional cry and said, "There are no Chinese people in there, right?"

Some people looked at Chen Fan.

"Then I can't save it. I have a fart relationship with me. Don't talk about the three views with me. After I have studied the matter, the theory still has to belong to you. I have enough food and support?"

Old Yuan sighed and said, "Save it."

Chen Fan looked at the others stubbornly and said: "For the face of the old man, I will save it. You will wait for me. Some of you regret it."
