生命是一首用泪与笑写成的诗。
Life is a poem written in tears and laughter.
"The only way to deal with the world is to laugh at it."
我们越是深入量子世界,就越意识到我们不知道的东西有多少。
Well may the boldest fear and the wisest tremble when they contemplate the condition of our country.
当他们思考我们国家的状况时,最勇敢的人可能会害怕,最聪明的人可能会颤抖。
States are inherently aggressive and expansionist.
