能量守恆定律/Conservation of Energy

能量守恆定律/Conservation of Energy

-- Source Credit

The source mentioned "conservation of energy." After seeing this clip, my first thought was: shouldn't it be "conservation of mass" instead? As a second thought, since E=M*C^2 "conservation of energy is more precise."

This is why nuclear weapons are so powerful. During nuclear reactions, a little mass is transformed into energy.

圖源提到「能量守恆定律」。一開始覺得:不是「質量守恆定律」嗎?後來仔細一想:既然 E=M*C^2,質量、能量可以互換,因此,說是「能量守恆定律」其實比較準確。

核子彈的威力會那麼強大的原因就是在核子反應時,有一點點質量會轉變成能源。



The reason anti-matter is so freaking powerful is, when contacting with matter, combined mass, unlike only a tiny fraction of mass in a nuclear reaction, of both matters is transformed into energy completely.

電影天使與魔鬼裡的反物質炸彈會那麼臭屁的原因之一是:當反物質接觸到物質時,反物質與物質都會一起完全轉化為能量,比核子反應時,只有一點點物質會轉化為能量還強大多了。
