Theory Quotes
-
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.
Joseph Story
-
If my theory of relativity is proven successful, Germany will claim me as a German and France will declare me a citizen of the world. Should my theory prove untrue, France will say that I am a German, and Germany will declare that I am a Jew.
Albert Einstein
-
In the first quarter of the nineteenth century the experimental proof for the interdependence of the composition and properties of chemical compounds resulted in the theory that they are mutually related, so that like composition governs like properties, and conversely.
Wilhelm Ostwald
-
It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing - a somewhat unfamiliar conception for the average mind. Furthermore, the equation E = mc², in which energy is put equal to mass, multiplied by the square of the velocity of light, showed that very small amounts of mass may be converted into a very large amount of energy and vice versa.
Albert Einstein
-
According to the kinetic theory of gases, the mean kinetic energy of a molecule is a measure of absolute temperature.
Wilhelm Wien
-
On quantum theory I use up more brain grease than on relativity.
Albert Einstein
-
Implication is thus the very texture of our web of belief, and logic is the theory that traces it.
Willard Van Orman Quine
-
The philosophy of reasoning, to be complete, ought to comprise the theory of bad as well as of good reasoning.
John Stuart Mill
-
No fairer destiny could be allotted to any physical theory than that it should of itself point out the way to the introduction of a more comprehensive theory, in which it lives on as a limiting case.
Albert Einstein
-
I started in 1921 to write on the foundations of an approach to international trade theory that was to some extent new and for which I received the inspiration during a stroll on the popular promenade Unter den Linden in Berlin in 1920.
Bertil Ohlin
-
You know, I have a theory about Charlie Haughey. If you give him enough rope, he'll hang you.
Charles Haughey
-
Had a theory that everyone has a relationship with words—whether they know it or not. It’s just that everybody’s relationship with words is different.
Benjamin Alire Saenz
-
I was an English major, so I love discussing possibilities and alternate theories.
William Mapother
-
Quantum mechanics is certainly imposing. But an inner voice tells me that this is not yet the real thing. The theory says a lot, but does not bring us any closer to the secrets of the "Old One." I, at any rate, am convinced that He is not playing at dice.
Albert Einstein
-
The man has a theory. The woman has hipbones. Here comes Death.
Anne Carson
-
Unfortunately for the good sense of mankind, the fact of their fallibility is far from carrying the weight in their practical judgement, which is always allowed to it in theory; for while every one well knows himself to be fallible, few think it necessary to take any precautions against their own fallibility.
John Stuart Mill
-
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? The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?
Stephen Hopkins
-
The unphilosophical majority among men are the ones most helplessly dependent on their era's dominant ideas. In times of crises these men need the guidance of some kind of theory; but, being unfamiliar with the field of ideas, they do not know that alternatives to the popular theories are possible. They know only what they have always been taught.
Leonard Peikoff
-
An ounce of practice is worth a pound of theory.
John Jacob Astor
-
The theory of the free press is not that the truth will be presented completely or perfectly in any one instance, but that the truth will emerge from free discussion
e. e. cummings
-
The power of a theory is exactly proportional to the diversity of situations it can explain.
Elinor Ostrom
-
Set theory in sheep's clothing.
Willard Van Orman Quine
-
In the theory of psycho-analysis we have no hesitation in assuming that the course taken by mental events is automatically regulated by the pleasure principle. We believe, that is to say, that the course of those events is invariably set in motion by an unpleasurable tension, and that it takes a direction such that its final outcome coincides with a lowering of that tension that is, with an avoidance of unpleasure or a production of pleasure.
Sigmund Freud
-
He's an amazing musician. He's from a totally musical background, not what I've come from at all; I'm completely self-taught. It probably shows in Jonny, he knows all the theory. But what's great about him is he's got that feel. I've never been interested in lead guitarists. He must be the only lead guitarist I like. I don't get Clapton. I don't get any of that stuff. But he's got an amazing feel, an amazing musicality.
