The really happy person is the one who can enjoy the scenery, even when they have to take a detour.[make the best of what is necessary...if you can't have what you love, love what you have...as there are lovable or at least positive aspects in everything, because anything could be worse]

In this model, the sun is a very tiny speck of dust indeed-a speck less than a three-thousandth of an inch in diameter ... Think of the sun as something less than a speck of dust in a vast city, of the earth as less than a millionth part of such a speck of dust, and we have perhaps as vivid a picture as the mind can really grasp of the relation of our home in space to the rest of the universe.

We may as well cut out group theory. That is a subject that will never be of any use in physics.

Life exists in the universe only because the carbon atom possesses certain exceptional properties.

The plain fact is that there are no conclusions. If we must state a conclusion, it would be that many of the former conclusions of the nineteenth-century science on philosophical questions are once again in the melting-pot.

The motion of the stars over our heads is as much an illusion as that of the cows, trees and churches that flash past the windows of our train.

Sciences usually advances by a succession of small steps, through a fog in which even the most keen-sighted explorer can seldom see more than a few paces ahead. Occasionally the fog lifts, an eminence is gained, and a wider stretch of territory can be surveyed-sometimes with startling results. A whole science may then seem to undergo a kaleidoscopic rearrangement, fragments of knowledge sometimes being found to fit together in a hitherto unsuspected manner. Sometimes the shock of readjustment may spread to other sciences; sometimes it may divert the whole current of human thought.
