The concept of computational complexity is not just about how fast we can compute, but also about understanding the limits of what can be computed.
计算复杂性的概念不仅仅是我们能计算多快，还包括理解什么是可以计算的极限。
In mathematics, the journey of discovery is as important as the destination.
We search through historical data looking for anomalous patterns that we would not expect to occur at random. Our scheme is to analyze data and markets to test for statistical significance and consistency over time. Once we find one， we test it for statistical significance and consistency over time. After we determine its validity， weask， ‘Does this correspond to some aspect of behavior that seems reasonable？’
当你评判别人时，你不是在定义他们，而是在定义自己。
