粒子

If we could actually see the path described by a particle, such as a sand grain in the rock, it would be more like that of a bluebottle path described by a particle, such as a sand grain in the rock, it would be more like that of a bluebottle buzzing round the room; it would be up and down, to and fro and from side to side.

假如我们真能看到诸如岩石中一个沙粒子的运动轨迹，那就像一只嗡嗡叫的绿头苍蝇在屋内飞行的轨迹，呈现出上上下下、来来回回、左左右右3种性质的运动。

Week 14 Regular nature of hydrogen atomic spectrum and Bohr hydrogen atom theory, wave –particle dualism of matter and uncertainty relation

第14周氢原子光谱的规律性和玻尔的氢原子理论；实物粒子的波粒二象性和不确定关系。

Combining the idea of quantization and the semi-classical hydrogen model of Bohr, the structure of atom is described. Solving the Schrodinger equation, the deduced wave function is related to the probability of finding the electron in space, a particle in the potential well and in a box. The concept of atom is expanded to the molecular and the energy band theory of solid state physics.

经由波尔之半古典的氢原子模型，结合量子化的概念以解释原子结构，并引入薛丁格方程式所求得之波函数与电子之空间机率的关系描述粒子波动特性，进而探讨位能井与氢原子光谱模型。
