Find a theoretical physics teacher

Is mass-energy conversion also called perpetual motion machine? That's achievable, don't all nuclear power plants run all over the world? Personally, I think that as long as it does not cost the earth's resources, it can be called a perpetual motion machine. For example, solar cells, anyway, the sun is burning when you don't need it, so you don't need to use it in vain!

I can tell you a research direction: the use of molecular diffusion motion to create a perpetual motion machine (in essence, it does not violate the balance of energy, and molecular motion is still heat energy from the sun, as long as it does not freeze), it will diffuse).You are a junior high school student, of course, I remember that molecular diffusion in biology class causes hydraulic differences, and if you can design different types of semi-permeable membranes that can withstand different hydraulic differences (I understand that the hydraulic difference has nothing to do with membranes, but I have not understood it in detail), you can realize the repeated circulation of liquids.

The small height difference is not a problem, anyway, it can automatically flow up one level at a time, and theoretically it can flow up the Himalayas if the number of upper levels is enough. The amount of water is small, and the bottom area can be larger.

If it can be achieved that different kinds of semi-permeable membranes can withstand different hydraulic differences, then that"Perpetual motion machine"Theoretically, it is achievable. Of course, it is necessary to solve the problems of membrane pollution, membrane aging and so on.

This was actually the idea I had right away when I was experimenting with biological semipermeable membranes in junior high school. I always thought it would work at first, but I never practiced it. Later, I checked the books related to semi-permeable membranes in the library, and found that the poor hydraulic pressure seemed to have nothing to do with the membrane, so I didn't study it carefully.

If you have figured out that the hydraulic differential can be different membranes or other methods to achieve the flow of liquid without external energy circulation (the external temperature is actually energy input, but it does not matter if it does not consume the earth's resources), then you can build a hydroelectric power building next to each housing building.

The world environment is better from now on, and energy is not in crisis.

Students have time to study, and when you go to work and are forced by life, you don't have time to study! Ninety-nine percent of the Chinese's talents are buried by life. Foreign countries have developed science and technology, others have good social security, and Swedes live well without working and only studying their own self-built aircraft.

The Chinese are only concerned with making money to support their families. If you have research, don't hit it, I hope you succeed.

A perpetual motion machine of the first type is not possible because it violates the first law of thermodynamics.

The second type of perpetual motion machine is not possible because it violates the second law of thermodynamics.

As for your statement that you want to unify the theory of relativity and quantum theory, the idea is very good, and I don't want to hit you.

1 Advanced Mathematics

2 Linear Algebra

3 Thermodynamics and Statistical Physics

4 Theoretical Theory

5 Electrodynamics

6 Quantum Physics

7 Advanced Quantum Mechanics

That's it.

You say you have a university level, just explain a few simple questions to me:

1 The Lagrangian principle in analytical mechanics.

2 The relationship and difference between Boltzmann distribution, Fermi distribution and Bose distribution.

3 The Galilean principle of relativity and the basic principles of inadaptation and special relativity.

4 The five basic assumptions of quantum mechanics and the Baoli matrix.

--Personally, I don't think a perpetual motion machine exists (if you're talking about a machine that can generate energy out of thin air).

According to my logic (not necessarily true), if you want to invent a perpetual motion machine, you have to come up with theories that can prove that a perpetual motion machine is possible, and before you can prove that the theory that a perpetual motion machine doesn't exist is wrong. In that case, the college-level physics teacher you're looking for won't necessarily be able to help you, because he has to prove that 90 percent of what he's learned is rubbish.

In order to dispel the idea of a perpetual motion machine, you can read "Theoretical Mechanics" and "Basic Thermodynamics" first, and of course before that, advanced mathematics.

If you really want to get involved in the essence of relativity, and quantum mechanics, in addition to advanced mathematics, you must have linear algebra, matrix theory, field theory, advanced analytic geometry (including popular, Riemannian geometry, etc.), probability theory and other mathematical foundations, thermodynamics and electrodynamics and other physical foundations. No matter how talented you are after graduating from college, you can only learn the skin of the skin, the basic principles of the basic principles. String theory is not an orthodox theory, and I don't understand it, so I don't pretend to understand it.

I'm not in a position to judge any of your ideas, but if you insist that a perpetual motion machine is possible, I'm happy to convince you.

According to the principle of entropy increase and the principle of conservation of energy, a perpetual motion machine is not possible. The principle of conservation of energy applies to both the macroscopic and microscopic realms. You still have to focus on efficient study, and learn mathematics well, which is the foundation of all natural sciences, otherwise you will not have a high attainment in physics, and you should not think about other things for the time being, you will naturally understand when you grow up.

The energy masses of matter can be converted into each other, and as long as no information is generated, this total amount will not be reduced".

How to do it without generating information? The argument for this topic may be more difficult to achieve than the perpetual motion machine itself. The essence of your idea is to prove that entropy can be reduced, and if this is proven, your perpetual motion machine is just around the corner.

Hehe, work hard, and if you get it, you'll make a great contribution. I couldn't get it out, and we didn't lose anything.

It depends on your supplement, it's still classical physics, if mass is converted into energy, the atomic bomb and the hydrogen bomb are like this.

I feel like you're on the wrong track.

I tell you, don't insult human intelligence here, you are human anyway, not aliens. Full of utilitarianism. None of the basic physical ideas. That little bit of thing in junior high school is the fur of fur. Don't read "A Brief History of Time" and say that you have taught yourself something.

Let's go learn math first.

The purpose of learning knowledge is to enrich oneself and better benefit mankind, not to think about how to win awards and be full of utilitarianism.

You want to unify the theory of relativity just because you win an award in the city? You're still a junior high school student, you'd better understand what you should learn first, Einstein proposed the theory of relativity in his 20s, are you smarter than Einstein? Scold..

Be deep.

Alas, I am also a junior high school student.

I also want to unify the gravitational and magnetic fields.

What foundation do you have?

Unifying the gravitational and magnetic fields was Einstein's last wish.

It's good to have an idea, but think of an idea!

Using motivation is not in line with energy conservancy!

Perpetual motion machines do not conform to conservation of energy.

Other theories are derived from the phenomenon of electricity and various forces.

Hope to give you a hint.

I'm probably around the level of theory in college (I've been self-taught for a long time now)."

It's still a long way off...

Physics teacher] Somehow, today I suddenly remembered him, my physics teacher, physics teacher. Maybe a new chemistry major is about to be added, and the situation is similar to that of a year ago. A year ago, I was promoted to the second year of junior high school, so I added "physics" to the curriculum.

Since then, the situation of "the number of words is extraordinary, and the political and historical places are divided" has been completely broken.

Remember the first physics lesson. The first physics class representative was a martial arts fan, and before class, he wrote the name of the physics teacher - "Dragon and Phoenix" on the blackboard, and it was also in traditional Chinese, he said that this writing was more chivalrous. Also, his name is also quite martial arts.

After the class, I found that Mr. Long was a new teacher, and he did not have the burly and serious "natural image" of the physics teacher, and he was still very thin and short. After introducing himself, he talked about physics: "Some students say that physics is difficult, but it is not.

Physics is not 'unreasonable', and 'unreasonable' is also "everyone is in an uproar." Finally, he gave us our first physics assignment: to write a short essay entitled "Physics Caprice".

Caprice, we think of caprice is "think casually, write whatever you want". So I handed it over in a daze. A few days later, the assignment came down, and he said:

You class 8 are very interesting. ”

As we all know, people in the Bashu region are influenced by the Sichuan dialect, and they speak Mandarin with a mouthful of Sichuan flavor, which is called "Trump". Teacher Long was not originally from this place, and after coming here, he was affected, and his language was very funny, integrating three "essences" into one, called "miscellaneous", and the middle school students' essay "Physics Teacher".

The classmates in my class were very "active" in class, and Mr. Long definitely couldn't greet him, so he shouted: "If you make trouble again, if you make trouble again, you will stand on the 'box' board" Everyone was unknown, and then burst into laughter. If you catch a "typical", you will say:

Are you done?! Still laughing ......

After entering the study of electricity, the knowledge points become abstract and difficult to understand. Another unit exam, after getting the paper, many people can't understand ......As you can imagine, the class did not do well. When commenting on the papers, Mr. Long said:

There were a few failed exams in this exam. The crowd rejoices. "It's just in the case of ten.

The crowd hit ed by him"However, this exam is a competition, so it should only be a test practice," everyone was relieved.

However, Mr. Long is good at summarizing the difficult points of knowledge to memorize, what "things are near and far, like changing rulers, opening their eyes and holding large", "left hand force and right hand flow", in this way, the boring theorem is easily mastered.

Mr. Long is an interesting person, so he has a good relationship with his students. Not only can he ask him questions about math and physics, but even if he goes to the office to fiddle with those physics equipment, he will smile and laugh at it. He wasn't tall, but he often played basketball and table tennis with us.

It's really "mingling"!

The clouds on the horizon gathered and scattered, scattered and gathered. There are many interesting things about Mr. Long. It's been a long time, but I really miss him!

Physics Teacher [The fastest and most sure way to conquer your fears and build your self-confidence is to do what you are afraid of until you have a successful experience. 】

Work done: w=147*10*4=5880w

Useful work = 50*

The efficiency is = 4900 5880 =

When g=10, the efficiency is:

One of the factors: the ambient temperature is not too low (higher than 0), and the water vapor can be liquefied into dew; If the temperature of the ring trousers is low enough (less than 0), the water vapor can condense into frost;

Factor 2: There is enough water vapor.

Remove the anti-flutter glassware from the refrigerator compartment and the indoor environment has water beads forming (liquefaction) on the surface of the glassware

Remove the object from the freezer compartment of the refrigerator, and the water vapor in the indoor environment can condense into frost on the surface of the orange.

Water vapor is cold into dew when noisy in the morning, and quick freezing into frost.

Inspection: Energize the empty Luda refrigerator for two hours, the refrigerator is exposed, and the freezer is frosted.
