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
Image
It's better to get mugged than to live a life of fear.
Freeman Dyson
Image
We cannot hope to either understand or to manage the carbon in the atmosphere unless we understand and manage the trees and the soil too.
Freeman Dyson
Image
As we look out into the Universe and identify the many accidents of physics and astronomy that have worked together to our benefit, it almost seems as if the Universe must in some sense have known that we were coming.
Freeman Dyson
Image
Now, as Mandelbrot points out, ... Nature has played a joke on the mathematicians. The 19th-century mathematicians may not have been lacking in imagination, but Nature was not. The same pathological structures that the mathematicians invented to break loose from 19th-century naturalism turn out to be inherent in familiar objects all around us.

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.

Plasma seems to have the kinds of properties one would like for life. It's somewhat like liquid water--unpredictable and thus able to behave in an enormously complex fashion. It could probably carry as much information as DNA does. It has at least the potential for organizing itself in interesting ways.
Freeman Dyson
Image
Everything in my life was luck. The key to having an interesting life is to always say yes to anything crazy.

Image
If women are doing a Ph.D., they have a conflict between raising a family or finishing the degree, which is just at the worst time - between the ages of 25 to 30 or whatever it is. It ruins the five years of their lives.
Freeman Dyson
Image
Mostly I'm just writing books for the public, and so I try to describe for the public what the choices are, what they might have to expect in the future and so by warning people ahead of time maybe you have an effect.
Freeman Dyson
Image
The world is just - it's wonderful when you look at all the detail. It's just amazing.
Freeman Dyson
Image
Mind and intelligence are woven into the fabric of our universe in a way that altogether surpasses our understanding.
Freeman Dyson
Image
All stable processes we shall predict. All unstable processes we shall control. Describing John von Neumann's aspiration for the application of computers sufficiently large to solve the problems of meteorology, despite the sensitivity of the weather to small perturbations.

The pain of childbirth is not remembered. It's the child that's remembered.

The technologies which have had the most profound effects on human life are usually simple.
Freeman Dyson
Image
A good cause can become bad if we fight for it with means that are indiscriminately murderous. A bad cause can become good if enough people fight for it in a spirit of comradeship and self-sacrifice. In the end it is how you fight, as much as why you fight, that makes your cause good or bad.

Just because you see pictures of glaciers falling into the ocean doesn't mean anything bad is happening. This is something that happens all the time. It's part of the natural cycle of things. We know from measurements that glaciers have been melting for 200 years at least.
Freeman Dyson

The technologies that raise the fewest ethical problems are those that work on a human scale, brightening the lives of individual people.
Freeman Dyson
Image
I have the freedom to do what I want... bright people to talk to every day.

That's, of course, the beautiful thing about science - that it's all about things we don't understand, not just the things we do understand.
