A fact is a simple statement that everyone believes. It is innocent, unless found guilty. A hypothesis is a novel suggestion that no one wants to believe. It is guilty, until found effective.
事實是每個人都相信的簡單陳述。它是無辜的，除非被證明有罪。假設(shè)是沒有人愿意相信的新穎建議。它是有罪的，直到被證明有效。
能量守恒定律不僅僅是一個抽象原則；它是已被無數(shù)實驗驗證的自然法則。
The beauty of physics lies in its ability to reveal the profound simplicity underlying the apparent complexity of the universe.
