“[The ceremonial key to the city of Padua] is engraved with a quote from Galileo that is also on display at the physics department of the university...'I deem it of more value to find out a truth about however light a matter than to engage in long disputes about the greatest questions without achieving any truth.”

“I tell you about a fact and truth. In physical reality of matter, there's no such thing as an imaginary spirit nor spiritual ghost. They are also made of matter, but totally different in size andlaws of physics which rule their life and the way they interact.”

“I want the key", he said. "The key to the universe. To life. To the future and the past. To love and hate. Truth. God. It's there. Inside of us. In the genome. The answer to every question. If I can find it. That's what I want," he finished, softly. "I want the key.”

“The world of science lives fairly comfortably with paradox. We know that light is a wave, and also that light is a particle. The discoveries made in the infinitely small world of particle physics indicate randomness and chance, and I do not find it any more difficult to live with the paradox of a universe of randomness and chance and a universe of pattern and purpose than I do with light as a wave and light as a particle. Living with contradiction is nothing new to the human being.”

“The truth is, the more one knows about Art, the more one values Entertainment.”

“The average newspaper boy in Pittsburgh knows more about the universe than did Galileo, Aristotle, Leonardo, or any of those other guys who were so smart they only needed one name.”
