Research is formalized curiosity. It is poking and prying with a purpose. 

They are ill discoverers that think there is no land, when they can see nothing but sea.

The atavistic urge toward danger persists and its satisfaction is called adventure.

The discovery of a new dish does more for human happiness than the discovery of a star.

Appearances are a glimpse of the obscure.

I learned to make my mind large, as the universe is large, so that there is room for paradoxes.

The eternal mystery of the world is its comprehensibility.

How gloriously legible are the constellations of the heavens!

Science is a cemetery of dead ideas.

A man of genius makes no mistakes. His errors are volitional and are the portals of discovery.
