从十分复杂的实验中所引导出来的一些 对称性，有高度的单纯与美丽。这些发展给 了物理学工作者鼓励与启示。他们渐渐了解 到自然现象有着美妙的规律，而且是他们可 以希望了解的规律

What?一定义和结果 1、什么是热分析动力学(KCE)?用热分析技术研究某种物理变化或化学反应(以下统称反应)的动力学 2、热分析动力学获得的信息是什么?判断反应遵循的机理、得到反应的动力学速率参数(活化能E和指前因子A等)。即动力学“三联体”(kinetic triplet)

薛定谔方程及其应用 微观粒子的基本属性不能用经典语言确切表达, “波粒二象性”借用经典语言进行互补性描述。 对微观客体的数学描述可以脱离日常生活经验,避免 借用经典语言引起的表观矛盾。 量子力学包含一套计算规则及对数学程式的物理解 释,是建立在基本假设之上的构造性理论,其正确 性由实践检验

Chapter 3 Kinematics I: rectilinear motion Motion implies change, and it is change make life-and physics-visible and interesting. Kinematics is the theory about the description of motion. Physical theories are creations of the human intellect; they must be invented rather than discovered
