The theory of computation provides a foundation for understanding what can and cannot be computed.
计算理论为理解什么可以计算、什么不能计算提供了基础。
In every line, there is a hidden truth.
端正其义而不谋求私利,阐明其道而不计较功利。
——〈在香港大学的演说〉(又名〈革命思想之产生〉),1923年2月19日
The beauty of mathematics is that it is both an art and a science.
The greatest art is found in the simplest moments of life.
写作是试图知道如果我们写作我们会写什么。
