If your theory is found to be against the second law of theromodynamics, I give you no hope; there is nothing for it but to collapse in deepest humiliation.
Arthur Eddington

My theory is this; I'm not a political songwriter. I'm an honest songwriter.
Billy Bragg

Any theory intended to describe and analyze socio-historical reality cannot restrict itself to the human spirit and disregard the totality of human nature.
Wilhelm Dilthey

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

In the book, I make the point that here we have string theory and here we have twistor theory and we don't know if either one of them is the right approach to nature.
Roger Penrose

They didn't accept me theory - not a theory, but just a thought I had about this character. I noticed that this man only exists when the boy comes into the grocery.
Omar Sharif

This success led my theoretical group to the chemical reactivity theory, extending more and more widely the range of compound and reactions that were discussed.
Kenichi Fukui

Moreover, in the experimental sciences, the scientific fraternity must test a new theory to destruction, if possible.
Peter D. Mitchell

I have a theory that the secret of marital happiness is simple: drink in different pubs to your other half.
Jilly Cooper

The theory of undirected evolution is already dead, but the work of science continues.
Michael Behe

If even in science there is no a way of judging a theory but by assessing the number, faith and vocal energy of its supporters, then this must be even more so in the social sciences: truth lies in power.
Imre Lakatos

About seven years later I was given a book about the periodic table of the elements. For the first time I saw the elegance of scientific theory and its predictive power.
Sidney Altman

Songwriting is different from music, although I don't deny now that it would be nice to have a little more background in music theory.
Neil Diamond

Even before I came to Chicago, I had gotten interested in the existence of dispersion of prices under conditions which economic theory said would yield a single price.
George Stigler

The classical example of a successful research programme is Newton's gravitational theory: possibly the most successful research programme ever.
Imre Lakatos

The major novelty of my theory was its claim that the most rapid evolutionary change does not occur in widespread, populous species, as claimed by Most geneticists, but in small founder populations.
Ernst Mayr

The standard growth theory tells us that economic growth in per capita basis comes from mainly two sources: capital deepening and total factor productivity growth, or TFP growth.
Toshihiko Fukui

Believing that the power to destroy belongs to the Creator alone I affirm... that any theory which, when carried out, demands the annihilation of force, is necessarily erroneous.
James Prescott Joule

My interest in economics has always been in the whole corpus of economic theory, the interrelationships between the various fields of theory and their relevance for the formulation of economic policy.
James Meade

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.
Kenichi Fukui
