What is a system? Here is my definition:
A system is a set of interrelated things that form a unified wholeI believe that reality is full of hidden systems and intellectuals should strive to understand these systems and make them clear. One example is the circulatory system of blood in the human body which was described in detail by William Harvey. Another important system is the structure of an atom which is studied by physicists. In my opinion, one of the most mysterious systems is the human brain.
