正如几何学最自然的起点是数学点，在观察和自然历史中采用同样的方法也最真实、简单且富有教益。
As in geometry the most natural way of beginning is from a mathematical point, so is the same method in observations and natural history the most genuine, simple, and instructive.
你无法管理你无法衡量的东西。
I am God's vessel. But my greatest pain in life is that I will never be able to see myself perform live.
真相很少是纯粹的，也从不简单。
The future belongs to those who understand that doing good and doing well are not mutually exclusive.
