Appearances are a glimpse of the obscure.

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

What one man can invent another can discover.

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

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

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

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

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

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

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

How gloriously legible are the constellations of the heavens!

New things are always ugly.

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