生命是一首歌,用你的方式唱它。
Mathematics is not just about numbers, equations, computations, or algorithms: it is about understanding.
The test of our progress is not whether we add more to the abundance of those who have much; it is whether we provide enough for those who have too little.
It is when we act freely, for the sake of the action itself rather than for ulterior motives, that we learn to become more than what we were.
We are all experiments in progress.
