To me, mathematics is like playing the violin. Some people can do it - others can't. If you don't have it, then there's no point in pretending.
Freeman Dyson
Image
If we had a reliable way to label our toys good and bad, it would be easy to regulate technology wisely. But we can rarely see far enough ahead to know which road leads to damnation. Whoever concerns himself with big technology, either to push it forward or to stop it, is gambling in human lives.
Freeman Dyson
Image
The ground of science was littered with the corpses of dead unified theories.
Freeman Dyson
Image
I like people who are working on practical things and who are working in teams. It's not so important to get the glory. It's much more important to get something that works. It's a better way to live.
Freeman Dyson
Image
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
All the time worrying about pushing the children and getting them to be mathematically literate and all that stuff. It's terribly hard on the kids. It's also hard on the teachers. And I think it's totally useless.
Freeman Dyson
Image
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.

Unfortunately the global warming hysteria, as I see it, is driven by politics more than by science.

If you go to London now, not everything is beautiful, but it's amazingly better than it was. And the Thames is certainly a lot better: There are fish in the Thames.

Humanity looks to me like a magnificent beginning but not the final word.
Freeman Dyson
Image
I mean science was blamed for all the horrors of World War I, just as it's blamed today for nuclear weapons and quite rightly.

The seeds from Ramanujan's garden have been blowing on the wind and have been sprouting all over the landscape. [On the stimulating effects of Ramanujan's mathematical legacy.]

It's better to get mugged than to live a life of fear.

It makes very little sense to believe the output of the climate models.
Freeman Dyson
Image
I think we're doing pretty well. It's clear the media, of course, always gives you the bad news.
Freeman Dyson
Image
We do not know how much of the environmental change is due to human activities and how much [is due] to long-term natural processes over which we have no control.
Freeman Dyson
Image
We simply don't know yet what's going to happen to the carbon in the atmosphere.

Almost everything about the universe is astounding.
Freeman Dyson
Image
The reason why new concepts in any branch of science are hard to grasp is always the same contemporary scientists try to picture the new concept in terms of ideas which existed before.

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.
