Don t be such a scientist How to talk about content in the information age

Don't talk about science with scientists, just like don't talk about learning with college entrance examination students.

Both sides of the equation ax+by = r are simultaneously dealt with d=(a, b), resulting in (a d)x+(b d)y = r d

Because d is divisible by a, and d is divisible by b, d is divisible by the equation to the left, i.e., the left side of the equation is an integer;

So the right side of the equation is also an integer, so d must be divisible by r

Qian Weichang, the father of Chinese mechanics, scored 0 points in mathematics in the college entrance examination.

y=(2015-8x), you can find the derivative first, or you can use the derivative of the composite function to find the derivative as follows:

y′=3(2015-8x)²•2015-8x)′=3(2015-8x)²•8)= -24(2015-8x)²。

If you are not familiar with it, you can change the element first: let u=2015-8x, then y=u, y (x)=y (u) u (x)=3u (8) = -24(2015-8x).

First of all, it's unlikely that scientists will have a score of 0 in math.

There is the writer Qian Zhongshu.

Hungary seems to be barely good at math alone. So it is not said that Chinese scientists aspire to the possibility of this country.

This one. Chinese and foreign ones are different.

Qian Xuesen:

Patriotic feelings above all else.

Qian Xuesen is already a first-class rocket expert in a leading position in the United States, enjoying favorable treatment, and has the status, reputation, and comfortable life that many people dream of all their lives, but he has never been prepared to live in the United States for a long time, and always wants to return to the motherland and use the knowledge he has learned to serve the motherland. Professor Shi said.

In the narration of the content of "Success and Fame, the Motherland in the Heart", Professor Shi vividly displayed the image of a scientist who loves the motherland and pretends to be the people in his heart in front of the audience through some small examples: "After Qian Xuesen returned to China, he said that during his stay in the United States, some people asked him several times if he had saved insurance money, but he said that he did not save a single dollar. Because he is Chinese, he does not plan to live in the United States for the rest of his life.

In his early years, Qian Xuesen was engaged in the research of applying the principle of wind tunnels to windmill power generation in the United States, and in the example calculation, the selected altitude ranged from sea level to more than 8 kilometers above sea level, which is the natural condition of the motherland, and his patriotic enthusiasm can be seen. ”

On September 7, 1950, Qian Xuesen was unjustifiably arrested by the U.S. Department of Justice. made American journalists exclaim that it was not Qian Xuesen who was interrogated, but the prosecutor! In 1955, after many hardships, Qian Xuesen finally returned to his motherland.

Madame curie.

Newton: He made a great contribution to science, was hit by an apple, and invented gravity.
