“Normal science, the activity in which most scientists inevitably spend almost all their time, is predicated on the assumption that the scientific community knows what the world is like... [It] often suppresses fundamental novelties because they are necessarily subversive of its basic commitments. Nevertheless, so long as those commitments retain an element of the arbitrary, the very nature of normal research ensures that the novelty shall not be suppressed for very long... [N]ormal science repeatedly goes astray. And when it does—when, that is, the profession can no longer evade anomalies that subvert the existing tradition of scientific practice—then begin the extraordinary investigations that lead the profession at last to a new set of commitments, a new basis for the practice of science. The extraordinary episodes in which that shift of professional commitments occurs are the ones known in this essay as scientific revolutions. They are the tradition-shattering complements to the tradition-bound activity of normal science.”

“Simplicity is the ultimate sophistication.
When once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been, and there you will always long to return.
Learning never exhausts the mind.
Art is never finished, only abandoned.
Painting is poetry that is seen rather than felt, and poetry is painting that is felt rather than seen.
The human foot is a masterpiece of engineering and a work of art.
It had long since come to my attention that people of accomplishment rarely sat back and let things happen to them. They went out and happened to things.
I have been impressed with the urgency of doing. Knowing is not enough; we must apply. Being willing is not enough; we must do.
As a well-spent day brings happy sleep, so a life well spent brings happy death.
Water is the driving force of all nature.”
