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

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

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.

New things are always ugly.

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

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

The unknown is the largest need of the intellect.

What one man can invent another can discover.

The eternal mystery of the world is its comprehensibility.
