Freeman Dyson quotes - page 6
Younger people have so many opportunities. I don't see any pessimism among them.
Freeman Dyson
It's not going to be just humans colonizing space, it's going to be life moving out from the Earth, moving it into its kingdom. And the kingdom of life, of course, is going to be the universe.
Freeman Dyson
The fact that the climate is getting warmer doesn't scare me at all. There's no reason why one should be scared.
Freeman Dyson
I'm a mathematician, basically. What I do is look around for problems where I can find useful applications for mathematics. All I do, really, is the math, and other people have the ideas.
Freeman Dyson
The public has a distorted view of science, because children are taught in school that science is a collection of firmly established truths. In fact, science is not a collection of truths. It is a continuing exploration of mysteries.
Freeman Dyson
Thirty-one years ago [1948], Dick Feynman told me about his "sum over histories" version of quantum mechanics. "The electron does anything it likes," he said. "It just goes in any direction at any speed, forward or backward in time, however it likes, and then you add up the amplitudes and it gives you the wave-function." I said to him, "You're crazy." But he wasn't.
Freeman Dyson
I believe global warming is grossly exaggerated as a problem. It's a real problem, but it's nothing like as serious as people are led to believe. The idea that global warming is the most important problem facing the world is total nonsense and is doing a lot of harm. It distracts people's attention from much more serious problems.
Freeman Dyson
Science and religion are two human enterprises sharing many features. They share these features also with other enterprises such as art, literature and music. The most salient features of all these enterprises are discipline and diversity. Discipline to submerge the individual fantasy in a greater whole. Diversity to give scope to the infinite variety of human souls and temperaments. Without discipline there can be no greatness. Without diversity there can be no freedom. Greatness for the enterprise, freedom for the individual - these are the two themes, contrasting but not incompatible, that make up the history of science and the history of religion.
Freeman Dyson
Euclid... gave his famous definition of a point: "A point is that which has no parts, or which has no magnitude." ...A point has no existence by itself. It exists only as a part of the pattern of relationships which constitute the geometry of Euclid. This is what one means when one says that a point is a mathematical abstraction. The question, What is a point? has no satisfactory answer. Euclid's definition certainly does not answer it. The right way to ask the question is: How does the concept of a point fit into the logical structure of Euclid's geometry? ...It cannot be answered by a definition.
Freeman Dyson
I have five minutes left to give you a message to take home. The message is simple. "God forbid that we should give out a dream of our own imagination for a pattern of the world". This was said by Francis Bacon, one of the founding fathers of modern science, almost four hundred years ago. Bacon was the smartest man of his time, with the possible exception of William Shakespeare.
Freeman Dyson
Trouble arises when either science or religion claims universal jurisdiction, when either religious dogma or scientific dogma claims to be infallible. Religious creationists and scientific materialists are equally dogmatic and insensitive. By their arrogance they bring both science and religion into disrepute. The media exaggerate their numbers and importance. The media rarely mention the fact that the great majority of religious people belong to moderate denominations that treat science with respect, or the fact that the great majority of scientists treat religion with respect so long as religion does not claim jurisdiction over scientific questions.
Freeman Dyson
I have to clear away a few popular misconceptions about space as a habitat ... It is generally considered that planets are important. Except for Earth, they are not. Mars is waterless, and the others are, for various reasons, basically inhospitable to man. It is generally considered that beyond the sun's family of planets there is absolute emptiness extending for light-years until you come to another star. In fact, it is likely that the space around the solar system is populated by huge numbers of comets, small worlds a few miles in diameter, rich in water and the other chemicals essential to life.
Freeman Dyson
Human beings are so constituted that we take for granted the fact that a direct awareness of our past selves is preserved... We take for granted the durability of the individual self. ...But ...the preservation of memories ...is as great an exercise in magic as the transfer of memories from the dead to the living. ...How the magic works ...is still a dark mystery. ...When once the technology exists to read and write memories from one mind to another, the age of mental exploration will begin in earnest. ...[W]e will look at nature directly through the eyes of the elephant, the eagle and the whale. We will... feel in our own minds the pride of the peacock and the wrath of the lion. That magic is no greater than the magic that enables me to see the rocking horse through the eyes of the child who rode it sixty years ago.
