现代科学技术突飞猛进、日新月异。对遥远庞大的天际,我们可以用万倍的望远镜去观察,对渺小幽闭的微观世界,我们也可以用显微镜去探索,唯独对我们--人类自己却难以用一样极其有效的工具去直接测量,这就是我们人类难于真正认识自己的原因。但是许多科学家和研究者依然十分执著,始终在研制一些量表,希望人们能够认识自己。 Modern science and technology by leaps and bounds, with each passing day. For the vast sky, we can observe with a thousand times the telescope. For the microscopic world of small claustrophies, we can also use the microscope to explore. Only for us, it is difficult for human beings to directly measure with extremely effective tools. This is why it is hard for human beings to truly recognize themselves. However, many scientists and researchers are still very persistent, always developing some scales, hoping people can know themselves.
