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

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

Science is a cemetery of dead ideas.

The eternal mystery of the world is its comprehensibility.

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

There are truths that prove their discoverers witless.

What one man can invent another can discover.

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

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.
