What one man can invent another can discover.

The eternal mystery of the world is its comprehensibility.

What one man can invent another can discover.

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

Nature has planted in our minds an insatiable desire to seek the truth.

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

Most new discoveries are suddenly-seen things that were always there.

How gloriously legible are the constellations of the heavens!

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.
