人们常只想到自己的需要，而没考虑自己的能力。王朔语录
The best designs solve problems you didn’t even know you had.
Engineering is about solving problems, not just making things look pretty.
Pleasure is the greatest good, and we should seek it and avoid pain.
The universe we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil, no good, nothing but blind, pitiless indifference.
