We teach a subject not to produce little living libraries on that subject, but rather to get a student to think mathematically for himself.
You can't just sit there and wait for people to give you that golden dream. You've got to get out there and make it happen for yourself.
唯一真正的发现之旅不在于寻找新的风景,而在于拥有新的眼光。
我长期以来认为独立是生活的最大祝福,是每一种美德的基础。
