I have never believed in the Wizard of Oz theory of consulting, that I am all-knowing and all-seeing, and that everyone around me is kind of a backbencher.
The classical example of a successful research programme is Newton's gravitational theory: possibly the most successful research programme ever.
My theory about actors is we're all walking milk cartons. Expirations dates everywhere.
Since Einstein developed his theory of relativity, and Rutherford and Bohr revolutionised physics, our picture of the world has radically changed.
Scientists have no agreed theory of the origin of life - plenty of scenarios, conjectures and just-so stories, but nothing with solid experimental support.
Creationists make it sound as though a 'theory' is something you dreamt up after being drunk all night.
The whole theory of the universe is directed unerringly to one single individual.
Religion is essentially the art and the theory of the remaking of man. Man is not a finished creation.
There's the theory that nudity doesn't really make something sexy; the characters and their relationship make it sexy.
I have this theory about science fiction movies in that, when the space race sort of died, a lot of people sort of lost hope.
It is disturbing to discover in oneself these curious revelations of the validity of the Darwinian theory. If it is true that we have sprung from the ape, there are occasions when my own spring appears not to have been very far.
During my years at the synchrotron laboratory, I had become interested in the theory of quantum electrodynamics and had decided that what I would most like to do after completing my dissertation work was to probe the short-distance behavior of the electromagnetic interaction.
There is no falsification before the emergence of a better theory.
Playing music is not really susceptible to theory much. Circumstances affect it so much.
The Freudian theory is one of the most important foundation stones for an edifice to be built by future generations, the dwelling of a freer and wiser humanity.
I always have said from the beginning of my career that I was going for the 'Geek Trifecta' because I'm such a total geek. I want to be in everything that has to do with the things that I enjoyed when I was a kid, which was 'Battlestar Galactica,' and being in 'Big Bang Theory,' and being in video games.
I had become interested in economics, an interest that was transformed into a lifetime dedication when I met with the mathematical theory of general economic equilibrium.
I have a theory that the only original things we ever do are mistakes.
Indeed, the history of 20th century physics was in large measure about how to avoid the infinities that crop up in particle theory and cosmology. The idea of point particles is convenient but leads to profound, puzzling troubles.
I never had a policy about marriage. I got married very young in life and I always think in all relationships, I've always thought that it's counterproductive to have a theory on that.
As for everything else, so for a mathematical theory: beauty can be perceived but not explained.
When I was in film school, I was learning more theory than practice.
I chose to deal with the science of cryptography. Cryptography began in mathematics. Codes were developed, even from Caesar's time, based on number theory and mathematical principles. I decided to use those principles and designed a work that is encoded.
When I dealt with set theory, I could never make it be the music that I wanted.
It is also a good rule not to put overmuch confidence in the observational results that are put forward until they are confirmed by theory.
There's that old theory that humankind and this planet were seen as the centre of the universe. That was thrown away - how could we be so presumptuous? Well, I subscribe to that.
Isn't it interesting that markets are not just perfect? In business school and economic theory, you learn all about those perfect markets, and there's no such thing as a perfect market.
A universe with a God would look quite different from a universe without one. A physics, a biology where there is a God is bound to look different. So the most basic claims of religion are scientific. Religion is a scientific theory.
The triumph is that the waveform we measure is very well represented by solutions of these equations. Einstein is right in a regime where his theory has never been tested before.
Land: A part of the earth's surface, considered as property. The theory that land is property subject to private ownership and control is the foundation of modern society, and is eminently worthy of the superstructure.
A feeble execution is but another phrase for a bad execution; and a government ill executed, whatever may be its theory, must, in practice, be a bad government.
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.
You know very well that unless you're a scientist, it's much more important for a theory to be shapely, than for it to be true.
My theory is if you have a religion, it's a good one. Because some people don't have any at all.
String Theory describes energy and matter as being composed of tiny, wiggling strands of energy that look like strings. And the pitch of a string's vibration determines the nature of its effect.
In the absence of evidence, superstition. It's a Middle Ages thing. That's my theory anyway.
