The eternal mystery of the world is its comprehensibility.

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

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.

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

What one man can invent another can discover.

One sees great things from the valley; only small things from the peak.

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

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

There are truths that prove their discoverers witless.
