Ye Yu's words made many people stunned.

Ideas?

Methodology?

It's true that when thinking about real problems, you don't need to be very precise about some concepts, but an accurate and rigorous line of thought is necessary, otherwise you don't know how to go.

When researching and thinking about problems, ideas and methods are the most basic things.

Ye Yu's point of view is indeed reasonable.

It's just that...... How can this mind jump so big?!

What about economics, how did you suddenly jump to science?

Seeing that everyone was puzzled, Ye Yu asked rhetorically: "I see that everyone seems to be surprised, then, let me ask you - isn't economics science?" ”

There are many things in this world that are like this, and everyone usually doesn't think much about it, or even realize it, but once someone asks it back, it is difficult to refute it after thinking about it carefully, and the word "no" can't be said.

Can you say that economics is not science?

Intuition tells everyone that it doesn't seem like they should say that.

"Economics is science!" Ye Yu affirmed, "Just from the perspective of the discipline to which economics belongs, it is. Because it's a social science! Usually, when we talk about the word science, we all think of physics, chemistry, biology and other disciplines, but who dares to say that economics is not a science?

It's just not a natural science!

In the broad definition of science, economics is science!

Don't think that this perception is irrelevant. The word science represents not only one or several disciplines, but also a way of thinking!

Economics is science! When it comes to studying economic problems, one cannot consciously exclude them from science.

Because cognition influences the way of thinking!

Important things to say three times.

I have just said three times that 'economics is science', and I believe you have all memorized it.

Well, journalist, could you please answer the question I just asked -- what is science, in your opinion? ”

For a long time, in the subconscious mind of many people, science is physics, chemistry and biology, and they know more about it. It is also known that geology is also part of the narrow science.

But economics?

Is economics a science?

A lot of people don't have that kind of awareness.

Ye Yu can be regarded as justifying economics in front of them this time.

This awareness is important. As Ye Yu said, cognition affects the way of thinking!

If you don't think of economics as a science, how can you treat it the way you treat science?

Only if you clearly understand that economics is also a science will you not fall through the road in some places.

What is science?

Zheng Chengan sneered slightly.

From small to large. This question has been mentioned by countless teachers and countless textbooks, and he can answer it without using his brain!

That's a ridiculous question!

He doesn't need to push through the old and say his opinion, he just needs to say the most correct answer!

Because that's what everybody says.

"Science is truth, science is correct understanding!" Zheng Chengan smiled confidently. replied.

Standard answer.

This is the most standard answer that has been learned since childhood.

In another classroom, Zhang Qi, a professor at the School of Physics, was interested.

At first, he was not interested in Ye Yu's lectures, and he would listen to them, just because the classmates in the class wanted to listen to them.

He just joined in the fun and watched it with him.

After all, what can an 18-year-old say?

Besides, he's a physics professor. Those who can continue to study in the field of physics, which most people think is boring, are basically very passionate about physics.

He had little interest in economics.

However, what he didn't expect was this. At the beginning of the lecture, the first question Ye Yu asked was - what is science?

What is science?

Very few people think deeply about it.

It's like no one thinks about what a cat is, what a dog is, what the number 1 is.

Although physics is the most representative of many disciplines that can be called science, although Zhang Qi is a researcher in the field of scientific research, to be honest, he has never thought about this question - what is science?

Suddenly, he realized that this was basically enough to be used by many people. Including the problem that you have overlooked, it is likely to be a very important question!

"Science is truth, science is correct understanding!"

This is Zheng Chengan's statement, and this is also a view that is deeply rooted in everyone's hearts.

Zhang Qi heard it.

Now. He was looking forward to Ye Yu's answer and the purpose of his question.

If Ye Yu agrees, then he is probably just asking this question to sensationalize people, to attract people's attention, and to lead to the following.

This answer is really boring.

Wakaba objected. Then he probably really thought deeply about this problem.

Zhang Qi looked forward to his opinion, because those who think deeply about this issue, whether they agree with it or not, at least - are worthy of attention.

In the auditorium, after Zheng Chengan's answer was spoken, everyone fell silent.

Because, the vast majority of people have no objections.

Freshmen, in particular, have no other opinions.

From childhood to adulthood, elementary school, junior high school, high school, teachers teach this way, and they learn this way.

They believed that Ye Yu also saw it this way, and he asked this just to lead to the next topic.

However,

"Wrong! Science is not truth! Ye Yu denied it without hesitation.

Science is not truth!

Ye Yu said that science is not the truth!

It is contrary to popular perception.

For a while, except for a very small number of people who held the same opinion, the vast majority of people were stunned!

"Science is truth! Ye Yu, don't talk nonsense, say some strange remarks to sensationalize! In the silence, Zheng Chengan shouted.

He was full of confidence, how could science not be the truth?

If science is not truth, then what is?

Ye Yu smiled and asked rhetorically: "In ancient times, people believed that the sky was round and the sun revolved around the earth. But the result? The earth is round, and it also revolves around the sun. This was definitely scientific at the time. Later, it was proven to be wrong, is science the truth? ”

"That's because the ancients were ignorant and had a limited understanding of the world!" Zheng Chengan retorted.

"Oh? Let me give you a more recent example. That time was too long ago, and you didn't have a sense of substitution. "Ye Yudao." The three laws of mechanics, it's scientific, right? Three hundred years ago, after it was proposed, physicists at the time even felt that the end of the world had arrived, because there was nothing else to study in physics! But what? In the micro field. Is it the truth? Is it the right understanding? It simply does not hold true in the micro realm! ”

"The three laws of mechanics are in the macroscopic field, and the theory of relativity is in the microscopic field, that is science and truth!" Zheng Chengan sneered. This level of rhetoric wants to refute me?

Hearing this, many people in the auditorium and in front of the computer nodded.

That's right, the three laws of mechanics in the macroscopic field and the relativity theory in the microscopic field, isn't this science? Isn't that the truth?

"Hundreds of years later, when a new theory appeared in the field of physics, it could explain the phenomena explained by the three laws of mechanics. It can also explain the phenomena explained by the theory of relativity. At that time, will there still be people who say that the three laws of mechanics in the macroscopic field and the relativity theory in the microscopic field are true? If they are truths, then what is that new theory? Ye Yu asked, "Don't think this can't happen!" How did people in ancient times predict the existence of the solar system?! How could people three hundred years ago predict that the three laws of mechanics would not hold true in the microscopic field?! ”

Zheng Chengan opened his mouth, but he couldn't say anything to refute it.

That's true, but why are you still unreasonable?

"You are quite unreasonable when you say that! What may or may not happen in hundreds of years can also be used as an argument? ”

"Unreasonable? Hehe...... First of all, if there is truth in science. Then it is not possible, it may not happen, it is inevitable, because truth can never be constrained by the microcosm! Secondly. And most importantly, truth has one of the greatest qualities, and that is that it is eternal! And what about science? The path of scientific development has always been that one theory overthrows another, and the new theory overthrows the old one! One is eternal, the other is constantly changing! Science and truth are fundamentally two different things! Ye Yu asked. There is truth in this world, but truth in no way includes science! Not to mention scientific theories! Even, science is not a correct understanding! It's just the right explanation! And it's a correct interpretation under certain constraints! ”

Ye Yu asked again: "You said that the ancients were ignorant and had a limited understanding of the world, so is our understanding of the world enough?" Science has advanced by leaps and bounds in recent years to convince us that our knowledge of the world is not enough, and that the human mind never ends! Since our knowledge of the world is not sufficient, can what we call science be the truth? Will it be the right understanding? ”

Zheng Chengan was speechless.

This time, Ye Yu did not mention the events hundreds of years later, but analyzed them from the characteristics and development of the two.

How can something that is constantly pushing through the old and overturning the opinions of its predecessors be the truth? Moreover, how can a constantly changing view be considered a correct understanding?

At best, it's the right explanation.

A correct explanation with constraints and a shelf life!

At this moment, all the teachers and students present, as well as the audience watching the live video, were dumbfounded.

Just now, just now, Ye Yu and the reporter staged an argument.

Obviously, what Ye Yu said is more reasonable.

Science and truth are the exact opposite of each other! How can science be the truth?

For the vast majority of people, this is the first time, the first time that someone has pointed out to them so clearly and unequivocally that science is not truth at all!

Of all the scientific theories today, none of them are true!

Because sooner or later they will be replaced by new theories, which is the law of scientific development!

"The development of science is never about replacing the wrong theory with the right theory, but about replacing the theory with strong explanatory power with little explanatory power! The human mind can be unfathomable, and what you think is a good theory today may be replaced by a better theory tomorrow! Science is not truth, and even what science pursues is not truth! Ye Yu said again.

Silent.

The whole venue was silent.

Suddenly, a young voice sounded: "What is science after?" ”

He asked everyone's thoughts.

"That's a good question! Science is not about being right or wrong! What science asks for is 'it possible to be overturned by facts'! It can be disproved by facts, but not overturned, this is the science that has been proven! Here, the most important thing is that science needs to be 'possible to be disproved by facts'! Ye Yu said loudly.
