※ 引述《euleramon (天佑台灣)》之銘言：
: 想請問一下
: 定律(law) 與 原理(principle) 的差異是什麼？？
: law有 Newton's laws of motion、snell's law、...
: principle有 Fermat's principle、Heisenberg uncertainty principle
: law 跟 principle 有什麼差別嗎？ 還是本質上他們就是一樣的東西？
: 感覺 law 的信服力會比 principle 高一點 orz"..
剛看到wiki有提到...
wiki內搜尋 Physical law：
By analogy, principles in other fields of study are sometimes loosely
referred to as "laws"
wiki內搜尋 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.
所以相較於law， principle 是可以應該在更多廣泛的自然現象
