“Fifty years," I hackneyed, "is a long time."
"Not when you're looking back at them," she said. "You wonder how they vanished so quickly.”

“Don't you believe in flying saucers, they ask me? Don't you believe in telepathy? — in ancient astronauts? — in the Bermuda triangle? — in life after death?
No, I reply. No, no, no, no, and again no.
One person recently, goaded into desperation by the litany of unrelieved negation, burst out "Don't you believe in anything?"
Yes", I said. "I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers. I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be.”
― Isaac Asimov

“What we observe is not nature itself, but nature exposed to our method of questioning.”
― Werner Heisenberg, Physics and Philosophy: The Revolution in Modern Science

“Tell me why the stars do shine,
Tell me why the ivy twines,
Tell me what makes skies so blue,
And I'll tell you why I love you.

Nuclear fusion makes stars to shine,
Tropisms make the ivy twine,
Raleigh scattering make skies so blue,
Testicular hormones are why I love you. ”
― Isaac Asimov
