There are encyclopedias of explanations of the law of conservation of energy, so I won't say much about it. However, I have some doubts.

Where does it apply? Encyclopedia says it's a closed system. Are the bottles with the lid closed and the car with the doors closed in the airtight system really conserved in them?

In a non-shady place during the day, where heat does not get inside the system? At any time, neutrinos can penetrate objects.

And in the dark or in the dark, can't neutrinos penetrate the system? When a neutrino passes through, there is no change in energy?

Closed systems exist in theory, but do they exist in real life? After listening to me, what do you think?

Mizukawa is really bold enough to take the law of conservation of energy. If other people hear it, they don't think it's a civil science?

If you think about it, it's true. Do you think dark matter and dark energy are in separate closed systems?

When it comes to the law of conservation of energy, I think of the conservation of cosmic symmetry. Didn't previous physicists think that the conservation of cosmology was universal?

Later, wasn't it partially overturned by the non-conservation phenomenon in the weak interaction force? That being the case, the law of conservation of energy is not necessarily entirely correct.

Or, the kind of conservation of energy that people understand is wrong. When it comes to conservation of energy, we have to mention the perpetual motion machine.

Many people deny the perpetual motion machine and say that it does not conform to the conservation of energy. I wonder if you're mistaken?

Who says that a perpetual motion machine must be a closed system? If not, then it would be inappropriate for you to use energy conservation.

Liuzi Fenglai is still as unconventional as ever. What they mean is that there is not such a large energy source to provide energy for the perpetual motion machine.

Yes, absolute containment systems really do not exist. However, after ignoring the small energy changes, the energy of a closed system remains conserved.

Obviously, such a large energy source is not easy to find. Through shapes, I knew that physics is inseparable from mathematics.

If you want to understand perpetual motion machines, you need to understand that one concept is to make it truly continuous and indisseparable. Speaking of which, some would say that this is in conflict with the energy of quantum mechanics.

Am I ready to overthrow quantum mechanics? Here it is necessary to distinguish between the natural and the man-made. Indeed, energy comes in pieces.

However, this does not mean that energy cannot be turned continuous. How is it continuous? Like water, of course not.

How to understand it? Just as you can't write the decimal in the closed interval [2,3], the energy of a perpetual motion machine is continuous.

Because of this, the perpetual motion machine can move all the time. Dueñas was even more daring, going so far as to say that energy can be continuous.

It's an enhanced version of water. It seems that Mizukawa Mi's words really let them fly themselves. Einstein's mass-energy formula says that mass and energy are two sides of an object, but I would like to ask why the mass of a uranium atom is so small, why is there so much more energy than an object of the same mass?

The reason is that there is still a lot of energy in the object that has not been released, and maybe one apple can be used as several nuclear bombs in the future.

Margarita said a few words, and then she was ready to say nothing. And Mizukawa began to speak of him.

Water says: It is wrong to think indiscriminately without understanding the scope of application of a law, and we should understand physical concepts more deeply.

Regarding the law of conservation of energy, let's go back and think about it. Maybe we'll talk about it next time.
