If you look broad enough, everything is encompassed in the natural sciences. Be it nanotechnology or economics; it comes under the broad definition of narrow sciences. When it comes to such a topic, one should study topics of a wide variety and stick to the basics.

Diverse knowledge of the basics will not only make a person more knowledgeable but also help him/her understand occurrences more easily as compared to a specialized person who has decided to stick to a single track.
