It is said that science has no academic field. What can prove this?

Science really has no national boundaries, so why don't American space scientists come to us and help us build spaceships? Then why don't Russian aviation scientists come to us to help us build aircraft engines?

I don't know why Yang said such a stupid thing that even primary school students can find reasons to refute. The person in charge of such a big internationally renowned company said that it is really rare to have no common sense.

If this makes people laugh, it comes from the mouth of celebrity Yang. I really don't know how he will face the refutation and questioning of the world. I don't think you can become an ostrich just by talking and not practicing.

I remember watching the vibrato video of Zheng Qiang, a famous professor and deputy secretary of the Party Committee of Zhejiang University. In response to the debate about whether science has no borders, Professor Zheng said with indignation that some celebrities now advocate that science has no borders, which is a big joke! People who say such things are almost ignorant.

Indeed, if science really has no national boundaries, why do so many scientific research in the United States, whether aerospace, information communication or biotechnology, basically exclude us scientists? Even, many times, even Chinese Americans are forbidden to participate.

American science is so developed that its important scientific fields will not be disclosed to any country, nor will other countries.

At present, a few scientists go abroad and don't return home. Their scientific spirit serves their own interests. No matter which country has interests, they will go. There are national boundaries between serving one's own country and serving other countries, which depends on whether scientists are willing to make spiritual and ideological contributions to the interests of their own country and people.

Therefore, it's not how high your IQ is, but your feelings of home and country and your ideology and morality that make you a university professor.

The United States used state power to suppress Huawei in China and detained Meng, the daughter of Huawei President Ren, for no reason. Nothing more than Huawei's 5G technology threatened the United States, and the United States used despicable means to deal with Huawei. Chip maker Qualcomm cut off supplies, as did Google's Android system, even though the company didn't need it at home. It also threatened to intimidate its allies not to use Huawei products by various means.
