There is an interesting display in New Asia College Library: I suppose it is a piece of arts; yet, it is highly scientific. When any one of the cogwheels is turned, all others will also turn at different time: sooner or later.

It implies the ‘butterfly effect’, where some small movements can lead to changes far far away. It also provide a complex network model, where the components are not connected through linear linkage. Furthermore, when we look at the cogwheels on the computer screen, they are somehow turning because of our visual illusion!

In my humble opinion, this piece of arts is a demonstration of the ‘fusion’ between arts and science; our society needs this kind of innovation to provide us with the driving force to move forward.
