Most people know that this is a derogatory term, but folk science does not refer to a folk scientist, a folk, a trained person, a teacher in an institution of higher learning, or a self-taught person. As long as he has scientific spirit, he can be considered a scientist, or at least a scientific man. However, folk science is not directly related to academic qualifications, status and education level. Folk science means that some people fabricate or denigrate scientific principles through their own imagination. Physics can be said to be the hardest hit area of folk science, because it is closely related to our lives and can attract people's attention most. For folk science, it is a subject that can be understood only by logical imagination without research.

In the field of mathematics, people's disciplines are usually invisible, because we just said that people's disciplines have no scientific spirit, so they will not conduct rigorous scientific research, and mathematics is the most accurate science, and people without a certain foundation cannot comment. Theoretically, it is difficult for us to fully understand folk science, so let's witness this magical world of folk science through those familiar folk science theories. A famous theory of civil science is that a huge magnet is installed in the front of the car, and then an iron arm is installed on the roof to extend to the front of the car, and a magnet is also installed to make the car move forward by itself under the attraction of the magnet, thus producing a perpetual motion machine. This is amazing.

If it is just imagination, it seems quite logical. But as long as you have some scientific knowledge, you will know that this is impossible. Because the role of magnets is mutual, and the magnets hanging on the front of the car are integrated with the vehicle itself, it is impossible to attract the vehicle to move forward. If the magnet is independent of the vehicle or installed at the rear of the front vehicle, it is also possible, but it is not a perpetual motion machine. People's subjects are particularly keen on studying perpetual motion machines, because perpetual motion machines look interesting and will become famous once they are invented. But the problem is that perpetual motion is absolutely impossible, as long as you have some common sense in physics, you can understand it. If he really made a perpetual motion machine, I believe no one in the world will thank him, because the whole physics system will collapse.

Folk science is a very interesting world. In the world of folk science, you will find that the world is full of miracles. In fact, it is a good thing to study and think about science, but it is not the right attitude to study science to stick to your own views seriously. Of course, not everyone is interested in science, but it doesn't matter if they are not interested. Delusion is wrong. A small amount of folk scientific theory can bring us joy, but if it is too much, it will also cause harm.
