The Dell Theory of Conflict Prevention argues that no two countries that are both part of the same global supply chain will ever fight a war as long as they are each part of that supply chain.
Thomas Friedman
Why should we, however, in economics, have to plead ignorance of the sort of facts on which, in the case of a physical theory, a scientist would certainly be expected to give precise information?
Friedrich August von Hayek
My theory is that everything an actor does, from the way he looks at his watch to the way he moves across the stage, is in the service of advancing a story, and in that sense, it’s all writing. In that sense we, while acting, write.
Bernard Sahlins
I grow daily to honour facts more and more, and theory less and less. A fact, it seems to me, is a great thing; a sentence printed, if not by God, then at least by the Devil.
Thomas Carlyle
When we first started ‘The Big Bang Theory,’ I would get incredibly nervous because it’s such a big show and I was just out of graduate school. I’d come in and have this huge responsibility for the one line that everyone hopes will bring down the house.
Kunal Nayyar
My first ambition in life, I made up my mind I was going to become Miles Davis. I studied music, music theory. I played trumpet for nine years. One day, my mother explained, ‘You can’t be Miles Davis. There’s one, and he’s got that job.’
Chris Gardner
The idea that women were oppressed throughout history is an appalling theory.

James Tobin
Every theory presented as a scientific concept is just that; it’s a theory that tries to explain more about the world than previous theories have done. It is open to being challenged and to being proven incorrect.
Marvin Harris
I always argued against the auteur theory; films are a collaborative art form. I’ve had some fantastically good people help me make the movies.
Alan Parker
The nature of catastrophe is, after all, reasonably unvarying in the way it ruins, destroys, wounds and devastates. But if something can be learned from the event – not least something as profound as the theory of plate tectonics – then it somehow puts the ruination into a much more positive light.
Simon Winchester
I tend to gravitate toward conflicted characters, and a character who is exploring chaos theory and population control and the difficulties of love and family is pretty rich.
Ed Stoppard
In its first 30 years of existence, up to the mid 1970s, the practical applications of game theory were very limited, probably as a result of excessive preoccupation by game theorists with cooperative solution concepts.
John Harsanyi
Why has not anyone seen that fossils alone gave birth to a theory about the formation of the earth, that without them, no one would have ever dreamed that there were successive epochs in the formation of the globe.
Georges Cuvier
Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe?
Stephen Hawking
So long as we use a certain language, all questions that we can ask will have to be formulated in it and will thereby confirm the theory of the universe which is implied in the vocabulary and structure of the language.
Michael Polanyi
The ‘science’ for which the United States is respected has nothing to do with the unscientific and baseless theory of evolution.
Ray Comfort
Science doesn’t work by voting. Did people vote on the theory of relativity? No! It’s either right or it’s wrong. Do we vote on whether genetics is a good theory or not? Of course not.
Alan Stern
I started out working on supersymmetry. The theory predicts that for every particle we know about, there will be an additional particle.
Lisa Randall
My roommate at Yale University introduced me to the auteur theory of filmmaking. I soon became a big fan of the works of John Ford, Kenji Mizoguchi, Ernst Lubitsch, and Stan Brakhage. I then decided to make my own films!

Gary Wolf
My theory in anything you do is to keep exploring, keep digging deeper to find new stuff.
Blythe Danner
Most mental health professionals, including clinicians

Most mental health professionals, including clinicians and researchers, endorse the deficit theory. They’re convinced that we wage war simply because we don’t know how to make love. We desperately want loving, satisfying relationships but lack the skills we need to develop them.
David D. Burns
Most of the stuff I learned to play, I learned in high school. I had a band in high school, a jazz-fusion thing, and I was the keyboard player. I was interested in how the instruments worked and the theory behind playing with them.
Brian McKnight
I cannot help fearing that men may reach a point where they look on every new theory as a danger, every innovation as a toilsome trouble, every social advance as a first step toward revolution, and that they may absolutely refuse to move at all.
Alexis de Tocqueville
At its best, management theory is part of the democratic promise of America. It aims to replace the despotism of the old bosses with the rule of scientific law. It offers economic power to all who have the talent and energy to attain it.
Matthew Stewart
I got expelled from high school, and then did my exams from home. I decided, through that experience, that I was going to expediate my plan and didn’t go to university. Instead, I went to a community college and studied the theory and history of film with the idea that I wanted to write and direct.
Charlie Hunnam
When I was at primary school, we had this theory that if you ate an egg, it meant you’d get pregnant and give birth to a chicken or another egg. It was something we dared together. I avoided eggs for years, but now they’re my favourite food.
Erin O’Connor
As you say, the way string theory requires all these extra dimensions and this comes from certain consistency requirements about how string should behave and so on.
Roger Penrose
Science has authority, not because of white coats, or titles, but because of precision and transparency: you explain your theory, set out your evidence, and reference the studies that support your case.
Ben Goldacre
When I was in college, I was a semiotics major, which is this hopelessly pretentious body of French literary theory.

Kenneth R. Miller
My ‘Big Bang Theory’ costar Johnny Galecki went off the grid. He bought a huge ranch and goes there every weekend. He keeps telling me to do the same thing, but I don’t know if I’m that committed. The Valley is as far off the grid as I’m going to go.
Kaley Cuoco
To put it bluntly, there isn’t one economic theory that can single-handedly explain Singapore’s success; its economy combines extreme features of capitalism and socialism. All theories are partial; reality is complex.
Ha-Joon Chang
I should point out, however, that at first some difficulty was experienced in observing the phenomena predicted by the theory, owing to the extreme smallness of the variations in the period of oscillation.
Pieter Zeeman
It was very useful to learn the history, the theory, and the art of building from a practical background.
Mario Botta
But the nature of my main work in chemistry can be better represented by more than 280 English publications, of which roughly 200 concern the theory of chemical reactions and related subjects.

The full name of string theory is really superstring theory. The ‘super’ stands for this feature called supersymmetry, which, without getting into any details, predicts that for every known particle in the world, there should be a partner particle, the so-called supersymmetric partner.
Brian Greene
I’m not that well-versed in literary theory – I don’t know what it is.
Jim Crace
I write music that sounds complex but isn’t. I frankly never think in terms of theory.
Eric Whitacre
The most important single thing about string theory is that it’s a highly mathematical theory, and the mathematics holds together in a very tight and consistent way. It contains in its basic structure both quantum mechanics and the theory of gravity. That’s big news.
Leonard Susskind
Today, the theory of evolution is an accepted fact for everyone but a fundamentalist minority, whose objections are based not on reasoning but on doctrinaire adherence to religious principles.
James D. Watson
When I was at Berkeley, the framework of quantum field theory could calculate the dynamics of electromagnetism. It could roughly describe the motion of the weak nuclear force, radiation. But it hit a brick wall with the strong interaction, the binding force.
David Gross
