Chinese science achieved different insights than the Greeks, who focused more on objects isolated from their context. When Aristotle tried to explain why a stone would fall, he speculated that it had a property of “gravity.” The Chinese, by contrast, viewed everything as existing in a field of forces and achieved a deeper understanding of topics such as magnetism, acoustics, and gravity—recognizing, for example, that tides were caused by the influence of the moon, something that even Galileo could not explain.
