Recently, the new science paradigm of computational science is emerging. Moreover, there are other emerging scientific topics such as system science and complex systems.
How can we compare those three new science items compared with conventional science paradigm items. One of the measures can be to test whether the considered system is insightful or not. If the investing system is insightful, it can be considered as simple system. Otherwise, it can be considered complex systems. The complex system is not insightful because the system has too many control parameters and so various input arguments.
