爱因斯坦写给女儿的信：爱是一切的答案！

This force explains everything and gives meaning to life. This is the variable that we have ignored for too long, maybe because we are afraid of love because it is the only energy in the universe that man has not learned to drive at will.
这个驱动力解释着一切，让我们的生命充满意义。这是一个我们已经忽略了太久的变量，也许因为我们害怕爱，因为这是宇宙中唯一的人类还无法随意驾驭的能量。
To give visibility to love, I made a simple substitution in my most famous equation. If instead of E = mc2 we accept that the energy to heal the world can be obtained through love multiplied by the speed of light squared, we arrive at the conclusion that love is the most powerful force there is, because it has no limits.
