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

How gloriously legible are the constellations of the heavens!

The unknown is the largest need of the intellect.

Every man takes the limits of his own field of vision for the limits of the world.

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.

When they shout “Long live progress,” always ask, “Progress of what?”

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

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

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

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

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

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