The feeling is constantly growing on me that I had been the first to hear the greeting of one planet to another.

There is no conflict between the ideal of religion and the ideal of science, but science is opposed to theological dogmas because science is founded on fact. To me, the universe is simply a great machine which never came into being and never will end. The human being is no exception to the natural order. Man, like the universe, is a machine.

There is no memory or retentive faculty based on lasting impression. What we designate as memory is but increased responsiveness to repeated stimuli.

Modern science says: 'The sun is the past, the earth is the present, the moon is the future.' From an incandescent mass we have originated, and into a frozen mass we shall turn. Merciless is the law of nature, and rapidly and irresistibly we are drawn to our doom.

When judging a product, we rarely have exhaustive scientific data to go by. As a result, if we are to form a complete picture, we must fill in the blanks, just as we must in our visual perception.

Nothing is less predictable than the development of an active scientific field.

Academically, I think things kicked off pretty late for me. I was kind of one of those kids who was in half honors, half regular. I was like a history/science kid, which was always weird. Around tenth grade or eleventh grade, everything started coming together.

I'm a science guy. I'm a geek. I love geology and botany and marine science. I thought maybe I'd be a professional guide, or maybe even a park ranger, working for the Department of Fish and Game.
