Zhou Huabin s academic experience

When encountering difficulties, he will investigate and study, which is a habit that Tao Hongjing has developed in the course of decades of study. Here's a very vivid story. One day, he read "The Book of Songs: Xiaowan"."The moth has a child, the moth bears (ambition), teaches the child, and the formula is like a valley"A few words, I was very unimpressed.

The old commentary on the Book of Songs says that the moth (a kind of thin-rumped bee) has males and no females. To reproduce offspring, the male takes the larvae of the moth (green spider) back into the nest and makes the larva become his own appearance and become offspring. It just so happened that a friend also came to ask what was going on.

He first went to check the book, and the book said exactly the same as the old commentary on the Book of Songs. He thought: I copied all these books from you, and you copied mine, and you can't find anything famous when you check the books.

Why don't I go and see it for myself? So, Tao Hongjing came to the courtyard and found a nest of moths. After several careful observations, he finally discovered that the moth larvae were not used to turn into moths.

Instead, they are placed in the nest and serve as their own eggs when they hatch larvae"Grain"。Moths not only have females, but also have their own offspring. The mystery of the larvae of the moth was finally debunked by Tao Hongjing by means of investigation and research.

From this incident, he came to a conclusion: We should attach importance to investigation and research in the administration of science, and we should not follow what others say ourselves. This shows the rigor of his scholarship.

Tao Hongjing sorted out the medical books, respected the original work very much, never scribbled and changed, nor did he believe it, even if there were supplements, he also distinguished his own statement from the original book. If the 365 kinds of medicines collected are added to the "Shennong's Materia Medica", he will use them"Black"Write and use some words"Red"Lettering. So, posterity has"Materia Medica deficit"，"Materia Medica, black letters"called.

The deficit is the text of the scripture, and the black letter is added later. He pioneered this practice, and later commentators rushed to learn from it.

Tao Hongjing sorted out the medical books, careful, rigorous, thorough, practical, is a mirror for us to sort out the ancient books of Chinese medicine today, worthy of a generation of famous doctors, passed down through the ages.

The world-famous falling body experiment.

Before Galileo, Aristotle of ancient Greece believed that objects fell differently and slowly. The speed at which it falls is directly proportional to its weight, and the heavier the object, the faster it falls. For example, an object weighing 10 kg will fall 10 times faster than an object weighing 1 kg.

For more than 1,700 years, this doctrine, which is contrary to the laws of nature, has been regarded as an unquestionable truth. The young Galileo, reasoning from his own experience, boldly questioned the doctrine of Aristotle. After much deliberation, he decided to do a hands-on experiment.

He chose the Leaning Tower of Pisa as his testing ground. On this day, he brought two iron balls of the same size but different weights, one weighing 100 pounds and being solid; The other weighs 1 pound and is hollow. Galileo stands on top of the Leaning Tower of Pisa and looks down.

Aristotle's theory can't be wrong! The experiment began, and Galileo took an iron ball in each hand and shouted: "People below, you see clearly, the iron ball is about to fall."

With that, he opened both hands at the same time. It was seen that two iron balls fell parallel to each other, almost simultaneously on the ground. Everyone was dumbfounded.

Galangelio's experiments revealed the secret of the motion of the falling body and overthrew Aristotle's doctrine. This experiment is of epoch-making significance in the history of physics.

Does education mean education? It's nothing more than passing the exam. Ancient scientific examination, modern college entrance examination.

The original "three" included the following:

Three hearts: Chen Jingrun said that learning should have three hearts: one is confidence, the second is determination, and the third is perseverance.

Three natures: Lu Xun's reading method can be summed up as follows: one is purpose, the second is flexibility, and the third is extensiveness.

Three times: Gao Shiqi said: "The things that are learned, one time to see the life, the second time to see the familiar, the third time to become friends." ”

Three surplus: Dong Yu of the Three Kingdoms said that he should learn with three more: "The winter is more than the year, the night is the day, and the rainy is sunny." ”

Three passes: Wang Guowei said that those who achieve great things must go through three passes: last night the west wind withered the green trees, went up to the tall building alone, and looked at the end of the world; The belt gradually widened and did not regret it, and made people haggard for Yi; The crowd looked for her thousands, and suddenly looked back, but the person was in the dim light.

Three kinds of studiousness: Liu Xiang of the Western Han Dynasty summarized three kinds of studiousness: "Less and studious is like the sunrise sun; Strong and studious, like the light of the day; Old and studious, like a candle. ”

Three tasks: Lenin listed three tasks for the younger generation: study, study, and study again.

Three minds: Chekhov summed up that there are three minds in life: a mind that is born, a mind obtained in books, and a mind acquired in life.

Three keys: The French writer Victor Hugo said: "The wisdom of entry holds three keys, one to open the numbers, one to open the letters, and one to open the notes." Knowledge, ideals, and fantasies are among them. ”

This is a process of continuous improvement of the realm of experience, as long as more attentive, more thinking, multi-faceted and multi-channel understanding, in order to gradually accumulate good academic habits, cultivate the quality and sentiment that a scholar can have, in order to make oneself from a layman of knowledge to a student, to become a scholar, to become a mentor, to become a leader, to have wisdom and strength.
