The language of mathematics is universal, transcending cultural and linguistic barriers.
数学的语言是普遍的,超越了文化和语言的障碍。
I'm a true believer that if you stay ready, you don't have to get ready.
Don't wait until everything is just right. It will never be perfect. There will always be challenges, obstacles and less than perfect conditions. So what. Get started now. With each step you take, you will grow stronger and stronger, more and more skilled, more and more self-confident and more and more successful.
世界上充满了这样的人,他们心目中令人满意的未来,实际上是对理想化过去的回归。
The best way to find out if you can trust somebody is to trust them.
