Ding Zhaozhong, a world-famous physicist and a Chinese American who won the Nobel Prize in Physics, once said "I don't know" about many questions when he was interviewed by CCTV's "Son of the East". In the previous stage, I heard that when he gave an academic report to teachers and students of China Southern Airlines, he was confronted with "three questions and three unknowns": "Do you think humans can find dark matter and antimatter in space?" I don't know. "Do you think the scientific experiment you are engaged in has any economic value?" I don't know. "Can you talk about the development direction of physics in less than 20 years?" "I don't know." I don't know if I ask three questions! This surprised all the students present, but soon won warm applause from the audience. Perhaps, when some people say "I don't know", they are often considered ignorant and ignorant. But Mr. Dante's "I don't know" embodies a kind of humility in life and a rigorous attitude of scientists in academic research, which can't help but make people respect.

Han Yu sharply criticized the bad habit of being ashamed to follow the teacher in the society at that time in Teacher's Theory: "If you don't follow the teacher, you will be confused, and you will eventually be incomprehensible." If you are confused and don't follow the teacher, the result is either confusion or ignorance.

This reminds me of what Confucius once said: "Knowing is knowing, not knowing is not knowing, but knowing is knowing." Confucius believes that learning is an honest thing, and admitting what you don't understand is itself an improvement of understanding. However, there are not a few people around us who either pretend to know or are self-righteous, too shy to ask. This kind of psychology and thought greatly inhibited our development, offset the talents and efforts of our classmates, and made their complacency more and more gloomy, so they lost their sense of ignorance and thirst for knowledge. If they don't know, they think they do. This is the most terrible thing.

However, those real scholars can always see their ignorance, because they know that there is no end to learning. Confucius once said, "I have nothing to do with what I don't know." Listen more, choose good and follow, see more and know, and know twice. "Confucius does not deny that he was born with knowledge, but he thinks he is not such a person. He has said many times that his achievements have benefited from being open-minded and eager to learn. Because of this, Confucius hated the behavior of pretending to understand and boasting.

There is an example: a young man was confused by Einstein, a famous scientist all over the world, and called himself "ignorant". So he asked Einstein this question. Einstein took out a piece of paper with a smile and drew two circles, one big and one small. Then pointed to the big circle and said, my knowledge circle is bigger than yours, and of course the contact surface of the unknown field is bigger than yours.

It can be seen that the more knowledge increases, the stronger the sense of ignorance, which is the common experience of great men and accomplished scholars. Descartes, a French mathematician, said: The more you study, the more you find your ignorance. So, now, we should understand the truth of learning. What reason do we have to "be confused and not follow the teacher"?

Opening the history of human progress, from ancient times to the present, and then to the future, is a process in which people's understanding of things around them has gradually improved from "ignorance" to "knowledge". This was the case in the past and will be the case in the future. Therefore, the development of human beings depends not only on understanding, but also on people with ignorant consciousness to explore.

Therefore, our generation of teenagers should sum up the lessons of their predecessors, ask when they have questions, ask consciously and have the courage to ask. Tagore painted such a picture for a self-righteous man: "Smoke boasted to the sky, and ash boasted to the earth, all of whom thought they were brothers of fire. Montaigne compared truly learned people to ears of wheat: "When they are still empty, they stand upright and disdain;" But at maturity, full of swollen wheat grains, they began to lower their heads and show no edge.
