Engels once said: "In the Greeks it was genius intuition, and here we are strictly scientific experimental-based research results, so it has a much more defined and understandable form. " Indeed, whether ancient Greece or ancient China once created a brilliant civilization, but it is not a culture suitable for scientific experiments; it is conducive to the production of intuition, experience, insight, and reason, but it is not conducive to the use of mechanical design and experimental techniques Dig a secret from nature. From this, we know:. ['A civilization that is not conducive to the development of scientific experimental technology cannot be regarded as a truly brilliant civilization.', 'Through scientific experiments, we can obtain research results in a more certain form.', 'Strict scientific experiments are a better way to discover natural secrets than intuitive experience.', 'Compared to other peoples of the time, ancient Greece and ancient China created a more brilliant civilization.']
