"Electricity is a renewable and clean energy ......"

"Report! May I ask your majesty, what is renewable? ”

"Renewable means something that can be generated repeatedly, such as hydropower, which we are going to study, as long as there is water in the river, it can continue to generate electricity."

"May I ask your majesty, what energy sources are non-renewable?"

"For example, the coal and oil we use for heating are not renewable energy, and if they are burned, they will be gone, and these substances will have to evolve over tens of millions of years, and it is impossible to produce coal and oil repeatedly."

"Oil? What is it? Your Majesty, please forgive Weichen for being lonely and unheard, I haven't heard of it. ”

"Huh! Oil is actually fierce fire oil, it can be burned to produce huge energy, is a precious non-renewable energy source in nature, such as Sakhalin Island has a large amount of oil. ”

……

In Yang Wenli's teaching class, it is often a new term that needs to be explained, otherwise everyone will not be able to understand it, so the teaching efficiency is not high, but it has finally begun scientific enlightenment.

He taught on the podium, and the students below took notes carefully, and everyone's enthusiasm for learning was very high, and they all asked questions bravely, after all, His Majesty personally taught, and they could be called real protégés of the Son of Heaven, which was a supreme honor.

Now it is a harsh winter, everyone sits in a warm room to class, it is not a waste of time, but Yang Wenli's task is very heavy, he not only has to teach, the most difficult thing is to write textbooks, basic physics, geometry, algebra, basic chemistry and other scientific knowledge, in this era, basically no, he has to write it out himself, he goes to class during the day, and has to write textbooks at night, living more tired than a dog.

But there is no way, this is related to whether his grand ideal can be realized, he must train a large number of qualified scientific assistants.

After two months of cramming education, Yang Wenli began to formally teach the basic knowledge of electricity, and also began to talk about the basic structure and principles of water turbines.

"In nature, metals as we know them are basically made up of atoms, which in turn are made up of tiny nuclei and electrons.

Because it is too small for us to see with the naked eye, we are reduced to the microcosm. In fact, it is also a world, and its counterpart is the huge planets and galaxies that we can see.

Taking the solar system as an example, the sun is a huge atomic nucleus, and our earth, metal, wood, water, fire, earth and other planets are electrons rotating around the sun at high speed.

The electrons in a metallic substance are constant electrons, which are fixed in an orbit that revolves around the nucleus of an atom and cannot escape, so the metal is not electric in normal times.

And the electrons that we produce by cutting the magnetic field are free electrons, which can move freely, and if we use metal as a carrier, then they accumulate at one end of the metal wire, and an electric potential is generated.

Potential is the accumulation of energy, electric potential is a very magical physical phenomenon, is an extremely microscopic phenomenon, we can not observe, so we can only boldly guess, the accumulation of a certain amount of free electrons to produce electric potential, it can squeeze out the constant electrons in the metal atoms, for substitution, one atom by one squeezing, it produces an electric current.

The process is very fast, almost equal to the speed of light, as long as the electric potential is large enough, almost a metal wire is connected, even if it is thousands of miles away, it is instantaneous, and we can get the same amount of electricity at the other end of the thousands of miles away.

It's a very remarkable physical phenomenon, and we can use this principle to do a lot of incredible things, such as transmitting energy, transmitting information.

This will increase our production efficiency and information efficiency by a thousandfold of all at once. ”

"The speed of light? Your Majesty, does light also have speed? ”

"Yes, light also has a speed, about 300,000 kilometers per second, light is not a substance, but an energy wave, in a vacuum, we can not see light, there is an infinite dead zone, there is no light and no sound, when the energy wave of light passes through our real world at high speed, the matter in the air is used as the carrier to emit visible light."

"The real world? Is there a non-real world? ”

"Yes, we usually refer to the matter that we can see and observe collectively as positive matter, and the matter that we cannot see or observe, but which really exists, is called antimatter.

In the vacuum environment in space, in fact, there are also a large number of substances, these substances, no matter what means we use, can not affect the slightest of them, because they are contrary to our real-world theories, and they are also separated by a heavy space, you feel that you exert force, but in fact, compared to them, you seem to be working hard through objects, and your efforts are completely in vain.

The space in which our human world is located is called the three-dimensional world, and the space dimension is a higher level of the world on top of the three-dimensional world, called the fairy world.

On top of the fairy world plus the time dimension is the god world, several great gods in our ancient mythology are gods, the so-called thirty-three days above, in fact, is the god world, immortals relative to us mortals have the power to penetrate the heavens and the earth, but they are not gods after all, and they also have the end of their life, they only have a lifetime of one epoch at the longest, which is 129,600 years.

An era is the longest time of a civilization, and when the time comes, there will be natural disasters that will destroy our civilization and the fairy world, most people and creatures cannot escape the disaster, but only some simple creatures can escape the catastrophe.

Of course, the god realm also has the misfortune of measuring calamities, and gods are not immortal, but their lifespans are too long, and they can live for a certain amount of tribulation, and a certain amount of tribulation is 50,000 yuanhui, or 6.48 billion years.

In fact, there is another realm above the divine realm, called the Founding God Realm, which is the founding god of our universe, whose lifespan is the same as that of the universe, which is 31.1 billion billion years. He has more life force than God, and any immortal god is alive and given by the founding god, so no immortal god can go against the will of the founding god, otherwise he can easily deprive you of your life. ”

Yang Wenli digressed as he spoke, he found that this world is not so simple, and scientific and technological civilization may have gone the wrong way, but he doesn't know the method of cultivating the truth and cultivating God, so he can only follow the honest Xiao Gui Cao and engage in scientific and technological farming.

But what he said was methodical, as if he was still above the founding god, and it really shocked the students below.

They are the real ancients, very much believe in the things of the gods, today listening to him, I really feel everything about the gods, I dream that one day I can fly to the world of immortals or gods, to be the immortals and gods who are infinitely free and have an infinite life.
