伽利略物理学数学化哲学思想基础析论

The Analysis on Philosophy Foundation of Galileo's Mathematical Physics

伽利略物理学数学化有其哲学思想基础。自然之书是由数学语言写成的,天上的世界与地上的世界是统一的,为其奠定了本体论基础,表明数学可以应用于对物理对象的认识中。数学知识具有逻辑必然性,人类能够通过数学推理获得关于物理对象的确定性认识,是其认识论信念,表明物理学的数学化认识是真的、有价值的。着眼于认识事物的外在特征而非内在本质,区分事物的第一性质与第二性质且对第一性质加以测量,使用理想实验或思想实验,将事物的性质与数量的表达联系起来,是其方法论策略,表明物理学数学化是现实可行的。

There's philosophy thinking based on Galileo's mathematical physics.The thought,the book of nature is written in mathematical language and the world of heaven and earth is united,is the ontological foundation.It indicates that mathematics can be applied to the researching of physical objects.Mathematical knowledge has the feature of logical necessity.Determinacy knowledge about physical objects can be acquainted.It's the epistemological belief that shows the knowledge about mathematical physics is true and valuable.To separate thing's first and second properties,measure first property with concentration of external characteristic,instead of internal essence,furthermore,to contact with the expression of thing's quality and quantity with idea experiment or thought experiment,is methodological tactic.It demonstrates possibility about mathematical physics in practice.
