02 能量：文明的標(biāo)尺和鑰匙
作為科技史的重要線索之一，能量是衡量文明的標(biāo)尺（Ian Morris & Nikolai Kardashev）渊季，人類的發(fā)展歷程就是能量持續(xù)正循環(huán)的過程螃壤；個體的進步要看是否能放大自己進步的臺階（能量使用效率）赐劣，人類的進步則要靠能量總量的提升映九，效率和總量同等重要嫉到。
Energy is the core clue of technology history as it is the scale of our civilisation (Ian Morris & Nikolai Kardashev). The history of humankind is the history of positive energy cycle. As personal development depends upon magnifying every piece of our achievement, i.e. an energy efficiency issue, the evolvement of mankind extols the surge of total energy. In this case, efficiency and quantity have gained relatively equal importance.
