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

There are truths that prove their discoverers witless.

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

Science is a cemetery of dead ideas.

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

True originality consists not in a new manner but in a new vision.

Appearances are a glimpse of the obscure.

How gloriously legible are the constellations of the heavens!

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

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