In scientific work, those who refuse to go beyond fact rarely get as far as fact. (Quote by - Thomas Huxley)

Many things difficult to design prove easy to performance. (Quote by - Samuel Johnson)

I can easily conceive, most Holy Father, that as soon as some people learn that in this book which I have written concerning the revolutions of the heavenly bodies, I ascribe certain motions to the Earth, they will cry out at once that I and my theory should be rejected. (Quote by - Nicolaus Copernicus)

Let us work without theorizing, 'Tis the only way to make life endurable. (Quote by - Voltaire)

It is on the acceptance or rejection of the theory of the Unity of all in Nature, in its ultimate Essence, that mainly rests the belief or unbelief in the existence around us of other conscious beings besides the Spirits of the Dead. (Quote by - H. P. Blavatsky)

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? (Quote by - Stephen Hawking)

Do not put too much confidence in experimental results until they have been confirmed by theory. (Quote by - Sir Arthur Eddington)

A theory is no more like a fact than a photograph is like a person. (Quote by - Edward W. Howe)

The absurd consequences of neglecting structure but using the concept of order just the same are evident if one examines the present terminology of information theory. (Quote by - Rudolf Arnheim)

Conjecture as to things useful, is good; but conjecture as to what it would be useless to know, is very idle. (Quote by - Samuel Johnson)

That is why one day I said my game will be like the Pythagorean Theorem - hard to figure out. A lot of people really don't know the Pythagorean Theory. They don't make them like me anymore. They don't want to make them like that anymore. (Quote by - Shaquille O'Neal)

A unified theory would put us at the doorstep of a vast universe of things that we could finally explore with precision. (Quote by - Brian Greene)

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. (Quote by - Jack Nicholson)

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. (Quote by - Richard Dawkins)

Beck said he didn't believe in the theory of a song coming through you as if you were an open vessel. I agree with him to a certain extent. (Quote by - Sheryl Crow)

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? (Quote by - Friedrich August von Hayek)

My theory of evolution is that Darwin was adopted. (Quote by - Steven Wright)

Entropy theory is indeed a first attempt to deal with global form; but it has not been dealing with structure. All it says is that a large sum of elements may have properties not found in a smaller sample of them. (Quote by - Rudolf Arnheim)

You cannot run a business, or anything else, on a theory. (Quote by - Harold S. Geneen)

We are all agreed that your theory is crazy. The question which divides us is whether it is crazy enough to have a chance of being correct. My own feeling is that it is not crazy enough. (Quote by - Niels Bohr)

I have a theory about the human mind. A brain is a lot like a computer. It will only take so many facts, and then it will go on overload and blow up. (Quote by - Erma Bombeck)

Your theory is crazy, but it's not crazy enough to be true. (Quote by - Niels Bohr)

My theory on housework is, if the item doesn't multiply, smell, catch fire, or block the refrigerator door, let it be. No one else cares. Why should you? (Quote by - Erma Bombeck)

Each pursues his own theory, little solicitous to correct or improve it by an attention to what is advanced by his opponents. (Quote by - Thomas Malthus)

Never worry about theory as long as the machinery does what it's supposed to do. (Quote by - Robert A. Heinlein)
