1913年，波尔提出了电子是按固 定轨道运行和电子只能处于一些 离散的稳定状态的假设。在此基 础上，他推动了新的原子理论的 发展。
Bohr
11
The word quantum derives from Latin, meaning “how great” or “how much”. In quantum mechanics, it refers to a discrete unit that quantum theory assigns to certain physical quantities. 量子这个词语来源于拉丁语，意思是“多大”或“多 少”。在量子力学中，它指一些不连续的物理量。
2
Is quantum mechanics far from us? 量子力学离我们真的很远吗？
No,it is just around us. 当然不是，它无处不在！
3
Laser 激光
4
Electron Microscope 电子显微镜
Scanning Picture 扫描图片
5
The theory of semiconductor based on quantum mechanics make information industry flourish. 基于量子力学的半导体理论，使信息产业蓬勃发展。
16
Until now , we know that both quantum mechanics and relativity theory are absolutely right . But there are some paradoxes between them ，which may be the origin of revolution theory . 迄今为止，我们知道量子力学与相对论都是非常正确的 理论。但是，它们之间还是存在一些不兼容的地方。这 些地方有可能成为未来革命性理论的起点。
• 1905年，爱因斯坦用普朗克 的量子假设成功地解释了光 电效应。
Einstein
10
In 1913，Bohr proposed that electrons travel only in certain orbits and that any atom could exist only in a discrete set of stable states，and developed a new theory of the atom.

Is quantum mechanics really complicated? 那么，量子力学真的那么复杂吗？ Absolutely not, it is very easy. 当然也不是，其实它是很简单的。

In 1900, Planck Put forward a hypothesis that energy is radiated and absorbed in discrete "quanta", or "energy elements", which successfully matched the observed patterns of black body radiation.
1900年，普朗克提出能量的发射和吸 收是按“一份一份”进行的假说 ，这 个假说成功的解释了黑体辐射模型。
Planck

In conclusion , there are two points: A . Quantum mechanics is founded by the hypothesis that energy is discrete . B . The core work of quantum mechanics is calculating the Schrödinger equation. So quantum mechanics is very easy. 总而言之，这儿有两点比较重要： A . 量子力学是以能量是不连续为假设建立的。 B . 量子力学的核心工作就是计算薛定谔方程。 所以说，量子力学是很简单的。

In 1926, Erwin Schrödinger formulated Schrödinger equation that describes how the quantum state of a physical system changes in time.
1926年，埃尔温·薛定谔提 出了薛定谔方程，这个方程 用来描述物理系统中量子态 是怎么样随时间变化的。
