"The chemistry of genetics is primarily the chemistry and structure of the hereditary nucleic acid chains, DNA and RNA, and of the proteins whose structure they in turn control and the mechanism of this control."

"It is a curious thing that relatively little attention has been directed toward working out methods for keeping the peace in a disarmed world. The technological The technological developments of the last twenty years have made disarmament a major concern of most nations, for it has become apparent that war is no longer an effective means for settling disputes between the great powers."

"The world has become too dangerous for anything less than utopias."

"Can Intelligence Survive? Looking at this nonclassical evolution of intelligence, one even begins to wonder whether it is such a small Law after all, even from the sun's point of view. Men create lakes and can level mountains; their atomic explosions have already shaken the whole earth's magnetic field; and they send out visible satellites and sensors that now range the solar system. Will the evolution of these powers of go on increasing? Or must it finally run down, was the sun does by the great Second Law? f we think about this problem in the light of the physical and biological regularities of behavior that we now know, it seems to me that we are led to a further rather surprising conclusion: There is no thermodynamic reason why evolution should ever stop. What evolution leads to is the larger and larger control of environment by the organisms, first by genetic natural selection; then, with the growth of societies and language, by cultural natural selection; and finally by brains. And once we pass a certain threshold of brains and intelligence we begin to know how to insulate ourselves against all sorts of environmental changes."

"If this property of complexity could somehow be transformed into visible brightness so that it would stand forth more clearly to our senses, the biological world would become a walking field of light compared to the physical world. The sun with its great eruptions would fade to a pale simplicity compared to a rose bush, an earth worm would be a beacon, a dog a city of light, and human beings would stand out like blazing suns of complexity, flashing bursts of meaning to each other through the dull night of the physical world between. We would hurt each other‘s eyes. Look at the haloed heads of your rare and complex companions. Is it not so? (p.151)"

"To say that basic science is exciting may sound like a contradiction... But I would remind you that there are two intellectual excitements that are not tame at all and that we remember all our lives. One is the thrill of following out a chain of reasoning for yourself; the other is the pleasure of watching several strongly individualistic personalities argue about their deepest convictions. That is to say, the thrill of a detective story and the pleasure of watching a play by George Bernard Shaw."

"Today we preach that science is not science unless it is quantitative. We substitute correlations for causal studies, and physical equations for organic reasoning. Measurements and equations are supposed to sharpen thinking, but, in my observation, they more often tend to make the thinking noncausal and fuzzy. They tend to become the object of scientific manipulation instead of auxiliary tests of crucial inferences. Many - perhaps most - of the great issues of science are qualitative, not quantitative, even in physics and chemistry. Equations and measurements are useful when and only when they are related to proof; but proof or disproof comes first and is in fact strongest when it is absolutely convincing without any quantitative measurement. Or to say it another way, you can catch phenomena in a logical box or in a mathematical box. The logical box is coarse but strong. The mathematical box is fine-grained but flimsy. The mathematical box is a beautiful way of wrapping up a problem, but it will not hold the phenomena unless they have been caught in a logical box to begin with."

"Going to the moon is not a matter of physics but of economics."

"I had the good fortune of having my first and only heart attack last January ... I call it good fortune because it taught me that there's a limited amount of time left and I better concentrate on one thing: How come existence? How come the quantum? Maybe those questions sound too philosophical, but maybe philosophy is too important to be left to the philosophers."

"I like to think that someone will trace how the deepest thinking of India made its way to Greece and from there to the philosophy of our times."

"For all our everyday experience, the geometry of space is smooth and flat. But as we examine it more closely, it must show oscillations. And still more closely, it must show foam, a foam-like structure. And that means that down at the very smallest distances, this idea of before and after really lose their meaning."

"Time is nature's way to keep everything from happening all at once."

"The first time I met Wheeler was in 1961, I was an undergraduate... with a somewhat unorthodox academic record. ...The hope was that ...I would be admitted as a graduate student... At the time I was working as a plumber... I was completely enthralled. John was enthusiastically describing his vision of how space and time would become a wild, jittery, foamy world of s when viewed through a tremendously powerful microscope. He told me that the most profound and exciting problem of physics was to unify Einstein's two great theories—General Relativity and Quantum Mechanics. He explained that only at the Planck distance would elementary particles reveal their true nature, and it would be all about geometry—. To a young aspiring physicist, the stuffy businessman exterior had morphed into an idealistic visionary. I wanted more than anything to follow this man into battle."

"Some people think Wheeler's gotten crazy in his later years, but he's always been crazy."

"The late, great astrophysicist, philosopher and black hole evangelist John Archibald Wheeler, of Princeton, used to say that the past and the future are fiction, that they only exist in the artifacts and the imaginations of the present."

"If I had to confess, under torture, right now, what I think the simple idea is, I would say it's that we ourselves generate the world; the world is self-generated. But it may well be absolutely wrong."

"What we think of as smooth simple space is really a wiggly business."

"The best way to learn something is to have to teach it."

"We will first understand how simple the universe is when we realize how strange it is."

"There are many modes of thinking about the world around us and our place in it. I like to consider all the angles from which we might gain perspective on our amazing universe and the nature of existence."

"We live on an island surrounded by a sea of ignorance. As our island of knowledge grows, so does the shore of our ignorance."

"Of all obstacles to a thoroughly penetrating account of existence, none looms up more dismayingly than “time.” Explain time? Not without explaining existence. Explain existence? Not without explaining time. To uncover the deep and hidden connection between time and existence, to close on itself our quartet of questions, is a task for the future."

"It from bit symbolizes the idea that every item of the physical world has at bottom — at a very deep bottom, in most instances — an immaterial source and explanation; that which we call reality arises in the last analysis from the posing of yes-no questions and the registering of equipment-evoked responses; in short, that all things physical are information-theoretic in origin and that this is a participatory universe."

"Is the very mechanism for the universe to come into being meaningless or unworkable or both unless the universe is guaranteed to produce life, consciousness and observership somewhere and for some little time in its history-to-be? The quantum principle shows that there is a sense in which what the observer will do in the future defines what happens in the past—even in a past so remote that life did not then exist, and shows even more, that 'observership' is a prerequisite for any useful version of 'reality'."

"Of all heroes, Spinoza was Einstein's greatest. No one expressed more strongly than he a belief in the harmony, the beauty, and most of all the ultimate comprehensibility of nature."

"Space tells matter how to move Matter tells space how to curve"

"Spacetime tells matter how to move; matter tells spacetime how to curve."

"Today I think we are beginning to suspect that man is not a tiny cog that doesn’t really make much difference to the running of the huge machine, but rather that there is a much more intimate tie between man and the universe than we heretofore suspected…The physical world is in some deep sense tied to the human being."

"We are participators in bringing into being not only the near and here but the far away and long ago. We are in this sense, participators in bringing about something of the universe in the distant past and if we have one explanation for what's happening in the distant past why should we need more?"

"The question is—what is the question?"

"Therefore we can afford many mistakes in the search. The main thing is to make them as fast as possible."

"My sophomore year, we were in Tallahassee and I ran a reverse very early in the game, and I remember being nailed by Jack Youngblood. I remember watching the ball being pitched to me and thinking, when the ball was about halfway, that it was kind of race to see whether he was going to get to the ball first or me. He was foaming at the mouth. I still have nightmares from the hit he gave me."

"I'd love to watch Jack Youngblood play. His tan arms hanging out of his sleeveless jersey, he'd put those pipes on the ground, and even at 240 pounds, he would show great moves and natural strength for an undersized player. He was extremely quick, had underrated strength, and he got great leverage against the tackles."

"You learnt that, whatever you are doing in life, obstacles don't matter very much. Pain or other circumstances can be there, but if you want to do a job bad enough, you'll find a way to get it done."
