We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special.
The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.
Look up at the stars and not down at your feet. Try to make sense of what you see, and wonder about what makes the universe exist. Be curious.
仰望星空，而不是低头看脚。试着理解你所看到的，并思考是什么让宇宙存在。保持好奇心。
Intelligence is the ability to adapt to change.
