数学的本质在于它的自由。
千丈长堤,可能因为蝼蚁的洞穴而溃决;百尺高楼,可能因为烟囱的缝隙冒烟而焚毁。
Wherever you go, you take yourself with you.
I always try to push myself to do better.
The best ideas often come from the most unexpected places; keep your mind open.
"El silencio también es una forma de expresión."
Poverty is not the issue, but greed is.
