I know that various authoritative organizations have given too many definitions and detailed explanations for the word "science". Here I just casually talk about my own thoughts. .

Since childhood, we have heard all kinds of words containing the word "science". For example, "What you are doing is unscientific. What I am doing is more scientific." "We must master scientific methods to do things." "We must develop scientific work and rest habits." These words must sound familiar to everyone. If we want to give examples of this kind of whispering, there must be many more. So what exactly is science?

My undergraduate major is physics, and physics is of course science. Later, I studied computer science in the postgraduate entrance examination, which of course is also a science. I have read books and learned knowledge for many years, but I am stuck in knowledge and can’t extricate myself. I rarely think about some essential questions: What is science? Why did we vigorously introduce science to China during the Republic of China? Why do everyone in modern society Talking about science, where does science come from and what impact does it have on us humans?

First of all, what I want to say is that science is by no means absolutely correct. Anyone who understands science as truth is wrong and does not truly understand the connotation of science. If we talk about absolute truth, then it may be religion or politics, but it is definitely not science. I think science is not a resultant thing, but a process and ideological thing. In other words, science is a way of thinking that understands and transforms the world. This way of thinking dares to admit one's ignorance. This kind of thinking The thinking method uses practice to promote one's own progress.

Why are the results of hundreds of thousands of years of human development before the Scientific Revolution not as fruitful as the results of the hundreds of years of development after the Scientific Revolution? The reason is that before the scientific revolution, humans thought they knew everything. Even if there were things they didn’t know, humans would not use practice to study or test them, but would use some of their own imagination to fill their ignorance. This is why humans With the advent of religion, there are various gods who are in charge of various affairs in the world. Later, the Europeans first discovered their ignorance and admitted that many observed and practical results were different from what they knew. Then they slowly transformed their previous cognitions into new ones that were more in line with the results of practical tests. Replacement with knowledge, this is the prototype of science. After the scientific revolution, because humans admitted their ignorance and tried their best to explore unknown things, all aspects have developed rapidly. Slowly, people discovered that as long as they mastered the rules, they could do anything, and the rules Proved that it can indeed be mastered.

Human beings have been self-righteous since ancient times and thought they knew everything. Europeans in the 15th century believed that the earth they lived on was the center of the universe. Even if someone observed some facts that were inconsistent with the geocentric theory, they turned a blind eye. People at that time believed that religion was infallible. You should believe unconditionally whatever religion tells you. Of course, in every era, someone discovers some new facts, but most of the time they discard these facts and continue to drift with the mainstream knowledge of the era. Now everyone knows that there was a great scientist in the 15th century - Copernicus. He observed many facts that were inconsistent with the geocentric theory. However, he did not turn a blind eye. Instead, he admitted human ignorance and believed that practice is the key to success. The only criterion for testing truth, so he boldly proposed the heliocentric theory. When everyone is moving in the wrong direction, it is very difficult for someone to move in a different direction than the wrong one. Not only can you not directly change other people's minds, but it will also offend the vital interests of many people, so Gebai Ni's heliocentric theory was not accepted at first. Scientific revolutions take a long time to bring about a shift in thinking.

The heliocentric theory proposed by Copernicus said that the sun is the center of the universe. Anyone with common sense in physics knows that the sun is not the center of the universe. We have not discovered the boundary of the universe yet, so where is the center? Therefore, Copernicus’ heliocentric theory is certainly not the truth. But why I call him a scientist is because his thinking is scientific thinking, which means he admits his ignorance and uses facts to improve his theory.

Science does not equal truth, and if it is science, it must be falsifiable. Falsification means that the theory can be proven to be false. Therefore, science has always been seeking the truth and getting closer to the truth.

We who have studied middle school physics all know Newton's three laws. Several laws proposed by Newton in 1666 laid the foundation of modern physics. However, classical Newtonian mechanics has long been proven to be incorrect. To be precise, it It is only close to the truth within a certain range, and beyond this range it is a fallacy. But no one can say that Newtonian mechanics is not science. In fact, it is the product of science.
