标题Re: [问题] 定律 与 原理 的差异
时间Sat Sep 5 11:23:53 2009
※ 引述《euleramon (天佑台湾)》之铭言：
: 想请问一下
: 定律(law) 与 原理(principle) 的差异是什麽？？
: law有 Newton's laws of motion、snell's law、...
: principle有 Fermat's principle、Heisenberg uncertainty principle
: law 跟 principle 有什麽差别吗？ 还是本质上他们就是一样的东西？
: 感觉 law 的信服力会比 principle 高一点 orz"..
刚看到wiki有提到...
wiki内搜寻 Physical law：
By analogy, principles in other fields of study are sometimes loosely
referred to as "laws"
wiki内搜寻 Physics：
The principles of physics find applications throughout the other natural
sciences as some phenomena studied in physics, such as the conservation of
energy, are common to all material systems.
所以相较於law， principle 是可以应该在更多广泛的自然现象
