三物理学与数学海森伯和狄拉克的风格为什么如此不同?主要原因是他们所专注的物理学内涵不同。为了解释此点,请看图4所表示的物理学的3个部门和其中的关系:唯象理论(phenomenolohgical theory)(2)是介乎实验(1)和理论架构(3)之间的研究。(1)和(2)合起来是实验物理,(2)和(3)合起来是理论物理,而理论物理的语言是数学。物理学的发展通常自实验(1)开始,即自研究现象开始。关于这一发展过程,我们可以举很多大大小小的例子。先举牛顿力学的历史为例。布拉赫(T.Brahe,1546-1601)是实验天文物理学家,活动领域是(1)。他做了关于行星轨道的精密观测。后来开普勒(J.
Three physics and mathematics Heisenbo and Dirac’s style why so different? The main reason is that they focus on different connotations of physics. To illustrate this point, look at the three departments of physics and their relationships shown in Figure 4: phenomenolohgical theory (2) is a study between experiment (1) and theoretical framework (3) . (1) and (2) are experimental physics together, (2) and (3) are theoretical physics, and the theoretical physics is mathematics. The development of physics usually starts from experiment (1), ie starts from the research phenomenon. We can cite many examples, large and small, about this development process. Take the history of Newtonian mechanics as an example. T. Brahe (1546-1601) is an experimental astrophysicist whose field of activity is (1). He made precise observations of the orbit of the planet.
