Perfect as is the wing of a bird, it never could raise the bird up without resting on air. Facts are the air of science. Without them a man of science can never rise.
尽管鸟的翅膀是完美的，但如果没有空气的支撑，它永远无法将鸟托起。事实是科学的空气。没有它们，科学工作者永远无法腾飞。
We are all in the gutter, but some of us are looking at the stars.
你只有在热爱的事情上才能真正有所成就。不要把金钱当作目标，而是追求你热爱的事物，并做到让人们无法将目光从你身上移开。
I am not wise, but I have learned a great deal simply by staying alive.
Materials speak their own language; our job is to listen and interpret.
