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

What one man can invent another can discover.

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

What one man can invent another can discover.

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

Science is a cemetery of dead ideas.

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