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

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.

The eternal mystery of the world is its comprehensibility.

One doesn’t discover new lands without consenting to lose sight of the shore for a very long time.

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

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

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

The unknown is the largest need of the intellect.

There are truths that prove their discoverers witless.
