Freedom is the right to tell people what they do not want to hear.
History is not the past. It is the method we have evolved of organizing our ignorance of the past.
出自唐代诗人韦应物《寄李儋元锡》，梁羽生在《大唐游侠传》中引用
The best decisions are made when you listen to both data and intuition.
战斗越艰难，胜利就越甜蜜。
The history of mathematics is a history of human thought and progress.
