His famous equation, E =mc 2 , did not appear with the paper, but came in a brief supplement that followed a few months later. As you will recall from school days, E in the equation stands for energy, m for mass, and c 2 for the speed of light squared.
他著名的等式E=mc^2在這篇論文中沒有出現，但出現在幾個月以后的一篇短小的補充里。你可以回憶一下學校里學過的東西，等式中的E代表能量，m代表質量，c^2代表光速的平方。
In simplest terms, what the equation says is that mass and energy have an equivalence. They are two forms of the same thing: energy is liberated matter; matter is energy waiting to happen. Since c 2 (the speed of light times itself) is a truly enormous number, what the equation is saying is that there is a huge amount—a really huge amount—of energy bound up in every material thing.
用最簡單的話來說，這個等式的意思是：質量和能量是等價的。它們是同一東西的兩種形式：能量是獲釋的質量；質量是等待獲釋的能量。由于c^2（光速的平方）是個大得不得了的數字，這個等式意味著，每個物體里都包含著極其大量——真正極其大量——的能量。
