Human beings, viewed as behaving systems, are quite simple. The apparent complexity of our behavior over time is largely a reflection of the complexity of the environment in which we find ourselves.
The sea is everything. It covers seven tenths of the terrestrial globe. Its breath is pure and healthy. It is an immense desert, where man is never lonely, for he feels life stirring on all sides.
The beauty of topological insulators lies in their robustness; their surface states are protected by symmetry and topology, making them immune to certain types of disorder.
The beauty of theoretical physics lies in its ability to describe the universe with a few simple equations, revealing the underlying simplicity beneath the apparent complexity.
