Freeman Dyson

Freeman Dyson
Freeman John Dyson FRSis an English-born American theoretical physicist and mathematician, known for his work in quantum electrodynamics, solid-state physics, astronomy and nuclear engineering. He is professor emeritus at the Institute for Advanced Study, a Visitor of Ralston College, and a member of the Board of Sponsors of the Bulletin of the Atomic Scientists...
kings cancer hands
Intelligence may indeed be a benign influence creating isolated groups of philosopher-kings far apart in the heavens... On the other hand, intelligence may be a cancer of purposeless technological exploitation, sweeping across a galaxy as irresistibly as it has swept across our own planet.
old-things entrepreneur tools
New directions in science are launched by new tools much more often than by new concepts. The effect of a concept-driven revolution is to explain old things in new ways. The effect of a tool-driven revolution is to discover new things that have to be explained.
heart thinking small-problems
For some days I quietly worked out in my own mind the metaphysics of Cosmic Unity. The more I thought about it, the more convinced I became that it was the living truth. It was logically incontrovertible. It provided for the first time a firm foundation for ethics. It offered mankind the radical change of heart and mind that was our only hope of peace at a time of desperate danger. Only one small problem remained. I must find a way to convert the world to my way of thinking.
order increase structure
The total disorder in the universe, as measured by the quantity that physicists call entropy, increases steadily over time. Also, the total order in the universe, as measured by the complexity and permanence of organized structures, also increases steadily over time.
bridges design essentials
The bottom line for mathematicians is that the architecture has to be right. In all the mathematics that I did, the essential point was to find the right architecture. It's like building a bridge. Once the main lines of the structure are right, then the details miraculously fit. The problem is the overall design.
divorce past facts
I am acutely aware of the fact that the marriage between mathematics and physics, which was so enormously fruitful in past centuries, has recently ended in divorce.
science imagination world
One factor that has remained constant through all the twists and turns of the history of physical science is the decisive importance of the mathematical imagination.
discovery heat thanks
Thanks to the discoveries of astronomers in the twentieth century, we now know that the heat death is a myth. The heat death can never happen, and there is no paradox.
philosophy philosophical one-direction
The progress of science requires the growth of understanding in both directions, downward from the whole to the parts and upward from the parts to the whole. A reductionist philosophy, arbitrarily proclaiming that the growth of understanding must go only in one direction, makes no scientific sense. Indeed, dogmatic philosophical beliefs of any kind have no place in science.
research doctrine tools
The great advances in science usually result from new tools rather than from new doctrines.
taken simplicity done
A model is done when nothing else can be taken out.
eye thinking hands
[On Richard P. Feynman's live demonstration of the rigidity of the O-rings when cold that doomed the space shuttle Challenger, killing seven astronauts:] The public saw with their own eyes how science is done, how a great scientist thinks with his hands, how nature gives a clear answer when a scientist asks her a clear question.
christian jesus good-luck
I had the good luck a few years ago to visit the archeological site of Zippori in Israel... I could see here displayed the Greek culture that Jesus decisively rejected, the same Greek culture that infiltrated the Christian religion soon after his death and has dominated Christianity ever since.
progress theory built
Progress in science is often built on wrong theories that are later corrected. It is better to be wrong than to be vague.
