Why do you move forward when rowing, the child asks how to explain it in scientific words!

This parent, first of all, understand what is called scientific method and what is called scientific proposition.

For example, the wise men of ancient times observed that the earth is the center of the solar system. 】

Is this the language of science? Most people say that it is nonsense. I can only laugh.

Get to a conclusion. Through their own observations, the ancients obtained information that the sun, moon and stars revolve around the earth, and then came to this conclusion without refuting the evidence. While we know this is wrong, the key to science is its process and attitude, not the outcome.

Another property of scientific propositions is falsifiability. In other words, all scientific rhetoric, in the end, will be proven wrong! Ancient science is falsified by modern science, and modern science will certainly be proven wrong in the future.

Einstein falsified Newton's law of gravitation, and Bohr falsified Einstein's strict law of cause and effect.

Here's another example: Some people say, I've seen a transparent dragon that no one else can see

Is this science? The answer is no. Because others can never prove that it is "fake".

Many people always say that many of the things that science says are wrong, and they have discovered many phenomena that science cannot explain. This is because our scientific atmosphere is really poor, and many people don't know what science is when they go to university. The purpose of science is to study the unknown and reach conclusions through objective and correct means, but not necessarily to get correct conclusions, and it is the charm of science to discover new areas in both success and error.

So: this is after the child asks you to explain in scientific words, you should give this task to the child. First tell him what phenomenon he saw when rowing, what people moved, how hard they worked, how the water moved, and then let the child push a wall, and ask him if the wall was pushing him when he pushed the wall.

The conclusion that the child himself summed up is a hundred times more precious than yours, and it doesn't matter if he is wrong. Finally, you can point out a little mistake in the child's theory (but don't point out all of them, let the child develop it himself), this is exactly the process of science, the child collects information, studies information, and reaches conclusions under the premise of objectivity rather than speculation, which is called science. If you prove the error of the child's theory, it is "falsification", which proves the inadequacy of the child's theory, and at the same time proves the correctness of the child's attitude throughout the process.

Therefore, don't instill a simple answer to your child, because that will lack the scientific attitude that should be taken correctly to a problem, and that kind of answer is worthless.

Child? Because the force is reciprocal, when you paddle backwards with the paddle you give the water a backward force, so the corresponding water will also give you a forward force to help your boat move forward...

professional explanations; Recoil, the person uses the oars to give the water backward momentum, and at the same time the boat receives the forward impulse, so the boat will move forward.

Action and reaction forces.

The slogan is: scientific and technological innovation, endless, explore mysteries, pursue truthHuman beings continue to move towards civilization because of scientific and technological innovation, development is inseparable from science and technology, and human beings and cities have an endless thirst for innovation; Human history, reality, and the future are full of mysteries, and "exploring mysteries" is human nature and the driving force for human development. The pursuit of objective truth and knowledge is the highest and eternal goal of man.

It is customary to link science and technology together, collectively referred to as "science and technology." In fact, the two are closely related, but also have important differences. Solve theoretical problems scientifically, and solve practical problems with technology.

The problem to be solved by science is to discover the relationship between conclusive facts and phenomena in nature, and to establish theories to link facts with phenomena.

The task of technology is to apply the results of science to practical problems. Science deals primarily with uncharted territory, and its progress, especially major breakthroughs, is unpredictable; Technology works in a relatively mature field and can be planned more accurately.

My grandmother will do this, every time I was scared when I was a child, my grandmother helped me call, and when I grew up, I began to learn, I was afraid that my grandmother's folk art would be lost, because no one in my father's generation wanted to learn. As far as I know, this doesn't seem to be scientific, maybe something we don't understand yet. But one hundred percent is sure that the effect is absolutely successful, my grandmother is kind to help and never charges, so there is no deception, it is indeed magical, continue to study and learn.

There's no scientific basis for it, but it's generally very useful.

This kind of thing is a custom.

How can it be explained scientifically ...

Startle is a phenomenon of autonomic nervous disorder, which can also be said to be the bioelectricity in our body, which is like a microcomputer in a car, controlling the functions of the whole body through nerve signals.

The principle is: when being called by others, it is a kind of normal person's mental adjustment to the disordered person, which includes a variety of factors such as guidance, care, thoughtfulness, spiritual comfort and biofield unity.

For example, when we meet several people fighting, we are disturbed, our hearts are very unbalanced, and we may even be angry or afraid. When we meet others who are elated, we are also happy.

In fact, it is none of our business, we are just disturbed by the biological field, and we are close to "unification" or "synchronization" with them.

Although this method is very simple and applicable, the success rate is not very high, because there are still many conditions that are not easy to achieve. For example, the closer the person to call, the higher the success rate, because the biological field between close people is easy to agree, when calling the heart will not be repulsed, easy to concentrate, if you change the outsider it is difficult to make a good job, in addition to the energy is not easy to concentrate, there is also the child's trust in the person who called, all have a great impact.

The child is frightened, so that he feels lonely and afraid, so crying, compared to the adult's betrayal, he can't express his feelings, and urgently needs the support of a partner, calling can make the child feel that you are always with the child, can feel his fear, understand him, although he doesn't understand what your name is, but he understands that he is not alone.

Believing in a daze is called superstition. Superstitious Buddha, Superstitious God, Superstitious Authority, Superstitious Expert, Superstitious Science, Superstitious Money, Superstitious Power, Superstitious .......

When a child is frightened, he has entered a state of fear, and screaming can make him return to a normal state from this state, and that's fine. I don't know if this explanation is the explanation of the scientific point you are talking about. But that's what it is, that's the reason.

There is no Amitabha Buddha in the south.

We also have this in Yancheng, Jiangsu, shouting souls! Some of them are pasted on the stove with Taoist charms, and some run out directly to shout, and the reason is incomprehensible.

You're a**, hehe, we have this method here too! There are eggs, there are embroidery needles, hehe! I can't explain this!

Soul calling. God knows how.

I wrote the story of Li Shizhen in the tone of a child, I hope it will be useful to you.

A long, long time ago, there was a child named Li Shizhen, who often collected herbs with his father and brother, and sometimes helped his father copy prescriptions and listen to his father explain pharmaceutical knowledge. When he grew up, he found that there were a lot of mistakes in the herbal books of the time. So, he decided to write a new Materia Medica.

He studied all kinds of books on the subject, and went to the deep mountains and old forests to collect medicinal materials, and through many years of hard work, he finally wrote the famous "Compendium of Materia Medica".

Edison liked to think of strange things, and he thought about it when he was in class. Discovered by the teacher and talking to his mother, his mother expressed her opinion of Edison, but the rigid teacher disagreed. When Edison found out, he decided to become a scientist.

Of course, the advantages of technological development outweigh the disadvantages.

The development of science and technology has brought about the application of electricity, which has enabled mankind to enter the age of electrical appliances and accelerated the pace of human progress. Otherwise, we're still lighting candles and water lamps.

The birth of communication equipment has made it possible for people to communicate without distance. The application of communication equipment in business, bringing about the rapid development of the economy, time is money, there is no communication equipment and only the efficiency of the flying pigeon book is really half a year can not do a business, how can the economy develop rapidly?

to computer and web applications. Needless to say, these two things were the greatest inventions of the 19th century. With these two things, complicated tasks in the past, especially data, can be easily completed on the computer. That's how efficiency improves.

In fact, *** also said that science and technology are the primary productive forces. I am absolutely convinced. In the last twenty or thirty years, that is, those of us born in the 70s and 80s can clearly witness the development of our hometown.

I believe that none of us dares to deny that it is not the benefits of technological development.

I think we sometimes produce"Whether the development of science and technology is good or bad"Such doubts may be because we sometimes feel that the richer the rich, the poorer the poor. People are rich, and we ourselves are still poor, and we can't afford better things, and we start to hate our own situation, and even start to hate our own parents for not being rich and complaining about God's injustice. And those who have the money go around squandering, even wasting.

In fact, if you want to go deeper, even if you go back to the ancient times when science and technology were not developed, it still appears"Zhumen's wine and meat stink, and there are frozen bones on the road"phenomenon. Who can be sure that there won't be their own inside the frozen bones?

Lida: Due to the backwardness of science and technology, the British and French forces will burn down the Old Summer Palace, and the Japanese will bully us for 8 years!!

Lida: The development of science and technology has extended the life expectancy of human beings a lot.

There is no doubt that it is a big disadvantage! Because even though the development of science and technology is quite rapid, every time science and technology develops, a large number of harmful gases and harmful substances will be discharged, which will have a considerable impact on human beings. Second, some people use advanced science and technology to spy on other people's privacy; If it is used internationally, it will have a greater impact, such as nuclear **, which will have a considerable impact.

Some people invent computers, some people make drugs, and some people check and kill drugs. They're just messing up Missy! ，

Benefit. Scientific development allows us to understand the world and ourselves, and improves work efficiency, quality of life, safety and health; and disaster prevention.
