"Science without borders" has two meanings: one is that scientific achievements can be shared by all mankind without borders; Second, no matter whether a scientific discovery or technological invention originally belongs to eastern science or western science, the whole human scientific community can learn to follow suit without borders. That's all. Science has no borders, and it doesn't have the meaning of "the science of western paradigm is the only science" that most people understand.
"Scientists have their motherland" means that as a scientist, we should be loyal to our motherland and not betray our motherland because of science.
"Science has no national boundaries, and scientists have the motherland" Pasteur said when he refused to accept an award from Germany, which launched the war against France. This means that although science has no national boundaries and is the common property of human beings, as a French scientist, Pasteur cannot accept the prize awarded by the invaders.
