"Science without borders" has two meanings: first, 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 science community can learn to follow suit without borders. That's all. Science has no borders, and it doesn't have the meaning that "the science of western paradigm is the only science" that most people understand.
"Scientists have the motherland" means that as a scientist, we should be loyal to the motherland and not betray the motherland because of science.
"Science has no borders, and scientists have their motherland," Pasteur said when he refused to accept the prize awarded by Germany, which launched the war against France. This means that although science has no national boundaries and is the common property of mankind, as a French scientist, Pasteur cannot accept the awards awarded by the invaders.
