A Quote by Freeman Dyson

...the computer models are very good at solving equations of fluid dynamics but very bad at describing the real world. The real world is full of things like clouds and vegetation and soil and dust which the models describe very poorly.

Conventional wisdom, fooled by our misleading "physical intuition", is that the real world is "continuous", and that discrete models are necessary evils for approximating the "real" world, due to the innate discreteness of the digital computer.

Doron Zeilberger

The climate-studies people who work with models always tend to overestimate their models. They come to believe models are real and forget they are only models.

Freeman Dyson

Until now, physical theories have been regarded as merely models with approximately describe the reality of nature. As the models improve, so the fit between theory and reality gets closer. Some physicists are now claiming that supergravity is the reality, that the model and the real world are in mathematically perfect accord.

Paul Davies

The best way to describe my work is comedy in a very, very real way. I'm not scared to look silly on camera. I take everyday situations we all go through and put a very real twist on it - things people can relate to.

Lilly Singh

Going back into the history of a word, very often into Latin, we come back pretty commonly to pictures or models of how things happen or are done. These models may be fairly sophisticated and recent, as is perhaps the case with 'motive' or 'impulse', but one of the commonest and most primitive types of model is one which is apt to baffle us through its very naturalness and simplicity.

J. L. Austin

Living is very serious, very real. It is also always a game. If we are wise, it is very real, very terrible, and very lovely, and a good deal of fun.

Eileen Wilks

Computer models of the climate....[are] a very dubious business if you don't have good inputs.

Freeman Dyson

There aren't very many good models of feminine rage - and the ones that we remember are ones where women take that anger internally and implode themselves in a real way, like Anna Karenina or Emma Bovary.

Lauren Groff

I can't live in a world where there are only, like, four kinds of women. Or where every woman is obsessed with cake. The very least I ask is that we have one female character in the world who likes savory things! I don't have any role models who like cheese!

Caitlin Moran

When I create characters, I create a world to inhabit and they begin to feel very real for me. I don't belong in a psych ward, I don't think, but they become very real, like my own family, and then I have to say goodbye, close the door, and work on other things.

Lois Lowry

Hume develops his arguments by a series of models. He doesn't call them models in the pretentious way in which we envelope, very often, pure banalities in this jargon

Lionel Robbins, Baron Robbins

You have this world of mathematics, which is very real and which contains all kinds of wonderful stuff. And then we also have the world of nature, which is real, too.

Freeman Dyson

I look at a show like 'Roseanne.' That's super influential on me. It's very funny, very real, with real problems. That was a big influence, and I don't know if you see that all the time in the network world.

Jonathan Krisel

I think I've owned all the models of iPods so far. And these days between my iPod, iPhone and my personal laptop computer, I'm someone who is very, very grateful for all the ways to listen to music and completely switch off from people around me and listen to the music in detail, which is very hard to do if you're in a room with other people.

Ian Anderson

One might think this means that imaginary numbers are just a mathematical game having nothing to do with the real world. From the viewpoint of positivist philosophy, however, one cannot determine what is real. All one can do is find which mathematical models describe the universe we live in. It turns out that a mathematical model involving imaginary time predicts not only effects we have already observed but also effects we have not been able to measure yet nevertheless believe in for other reasons. So what is real and what is imaginary? Is the distinction just in our minds?
