通往力量的道路总是在建设中。

"Books are the mirrors of the soul."

The struggle for survival is the essence of life.

The total amount of suffering per year in the natural world is beyond all decent contemplation. During the minute that it takes me to compose this sentence, thousands of animals are being eaten alive, many others are running for their lives, whimpering with fear, others are slowly being devoured from within by rasping parasites, thousands of all kinds are dying of starvation, thirst, and disease.

物理系统的对称性反映在其能级的简并性上。

真相很少是纯粹的，也从来不是简单的。

追求卓越是一段永无止境的旅程。
