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

What one man can invent another can discover.

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

Appearances are a glimpse of the obscure.

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

The eternal mystery of the world is its comprehensibility.

Science is a cemetery of dead ideas.

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

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

How gloriously legible are the constellations of the heavens!
