一个时期的公理的正确程度,取决于这个时期的科学水准。那么,这一时期的所有绝对物理量,都带有同公理相同水准的正确程度,虽然这些物理量的性质似乎可以由经验得到,但科学体系上不允许有这么多的经验。公理化要求我们用最少的公理,得到最完整的体系理论。经典力学是人类文明史上最早树立的里程碑,它直到现在,还是我们从事建筑业,制造业,科研等活动的基础科学。但在许多教材中,总喜欢在一开始便一口气拖出五六个绝对量出来,似乎它们都是经验,不用推敲,其实它们大多数是在一个经验公理的照耀下产生出 The correctness of the axiom of a period depends on the scientific standard of this period. Then all the absolute quantities of physics during this period are all at the same level of correctness as the axioms, and although the nature of these quantities appears to be empirically obtainable, so much experience is not allowed in the scientific system. Axiomatization requires us to use the least axioms to get the most complete system theory. Classical mechanics is the earliest milestone in the history of human civilization. Until now, it is still the basic science that we are engaged in in the fields of construction, manufacturing, scientific research and so on. However, in many textbooks, I always like to pull out the absolute amount of five or six breaths at the beginning, as if they are all experiences without scrutiny. In fact, most of them are produced under the influence of an empirical axiom
