Freeman Dyson Quotes

I have felt it myself. The glitter of nuclear weapons. It is irresistible if you come to them as a scientist. To feel it's there in your hands, to release this energy that fuels the stars, to let it do your bidding. To perform these miracles, to lift a million tons of rock into the sky. It is something that gives people an illusion of illimitable power, and it is, in some ways, responsible for all our troubles — this, what you might call technical arrogance, that overcomes people when they see what they can do with their minds.

To talk about the end of science is just as foolish as to talk about the end of religion. Science and religion are both still close to their beginnings, with no ends in sight. Science and religion are both destined to grow and change in the millennia that lie ahead of us, perhaps solving some old mysteries, certainly discovering new mysteries of which we yet have no inkling.

In my opinion, the black hole is incomparably the most exciting and the most important consequence of general relativity. Black holes are the places in the universe where general relativity is decisive. But Einstein never acknowledged his brainchild. Einstein was not merely skeptical, he was actively hostile to the idea of black holes. He thought that the black hole solution was a blemish to be removed from his theory by a better mathematical formulation, not a consequence to be tested by observation. He never expressed the slightest enthusiasm for black holes, either as a concept or as a physical possibility. Oddly enough, Oppenheimer too in later life was uninterested in black holes, although in retrospect we can say that they were his most important contribution to science. The older Einstein and the older Oppenheimer were blind to the mathematical beauty of black holes, and indifferent to the question whether black boles actually exist.

How did this blindness and this indifference come about?

Robida in 1883 published cartoon pictures of flat television screens, test-tube babies, bomber airplanes, and chemical warfare. Robida understood, as Verne and Wells did not, that the twentieth would be the century of world wars.

The international community of scientists may help to abolish war by setting an example to the world of practical cooperation extending across barriers of nationality, language, and culture.

Around every large center of scientific research we find a swarm of craft industries. Silicon Valley grew around
Stanford, the Route 128 corridor around Harvard and MIT, the US1 corridor in New Jersey around Princeton and Rutgers.

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.

An awareness of our smallness may help to redeem us from the arrogance which is the besetting sin of the scientists.

Life had to invent death to evolve.

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.

The Yahuda collection gives us an intimate view of Newton's religious thinking, which was as intense and idiosyncratic as his thinking about alchemy and mathematical physics. He saw clearly that there is no firm basis in scripture for the orthodox Christian doctrine of the Trinity. He was a Unitarian, deducing from the evidence of scripture that God the Father reigns alone. There is one God and not three.

The seeds of Tolstoy's gospel of nonviolence fell mostly upon stony soil as they were carried all over the world, and nowhere was the soil stonier than in his native Russia.

In every civilization, the skilled artificer has an honored place beside the scribe and the shaman. Our own civilization is no exception.

The poorer half of humanity needs cheap housing, cheap health care, and cheap education, accessible to everybody, with high quality and high aesthetic standards. The fundamental problem for human society in the next century is the mismatch between the three new waves of technology and the three basic needs of poor people. The gap between technology and needs is wide and growing wider. If technology continues along its present course, ignoring the needs of the poor and showering benefits upon the rich, the poor will sooner or later rebel against the tyranny of technology and turn to irrational and violent remedies. In the future, as in the past, the revolt of the poor is likely to impoverish rich and poor together.

The primary difference between the classical layer and the quantum layer is that the classical layer deals with facts and the quantum layer deals with probabilities. In situations where classical laws are valid, we can predict the future by observing the past. In situations where quantum laws are valid, we can observe the past but we cannot predict the future. In the quantum layer, events are unpredictable.
