Theorists Quotes : pic 001167825
I'm a student of patterns. At heart, I'm a physicist. I look at everything in my life as trying to find the single equation, the theory of everything.

The love of theory is the root of all evil.
Theorists Quotes : pic 001273925

Theory now: concern for truth must not hobble our discussion.

The formal scientific definition of theory is quite different from the everyday meaning of the word. It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence.
Theorists Quotes : pic 001375251
Without clues, we search in the wrong directions. Without evidence, a theory is not reliable.
Theorists Quotes : pic 001668792
People with theories of life are, perhaps, the most relentless of their kind, for no time or place is sacred from their devastating elucidations.
Theorists Quotes : pic 000661620

Theorists Quotes : pic 000422369
For me, theory has always opened things up to where I can walk into a room and just by hearing something I know exactly where to go on the guitar. I have a better time playing because I have a variety of colors to bring to the table.
Theorists Quotes : pic 000773601
Theory is splendid but until put into practice, it is valueless.
Theorists Quotes : pic 000666515
Every hypothesis is a construction, and because of this it is an authentic theory.

I'm not a conspiracy theorist - I'm a conspiracy analyst.
Theorists Quotes : pic 001393213
We are dreamers, shapers, singers, and makers.We study the mysteries of laser and circuit, crystal and scanner, holographic demons and invocations of equations. These are the tools we employ and we know many things.
Theorists Quotes : pic 001869021

Theorists Quotes : pic 000798553
Theorists tend to peak at an early age; the creative juices tend to gush very early and start drying up past the age of fifteen-or so it seems. They need to know just enough; when they're young they haven't accumulated the intellectual baggage.
Theorists Quotes : pic 000028869
I'm a theorist, not an institutionalist.
Theorists Quotes : pic 000402362

Theorists Quotes : pic 000037013
A theory not only explains the world we see, it lets us imagine other worlds, and, even more significantly, lets us act to create those worlds. Developing everyday theories, like scientific theories, has allowed human beings to change the world.
Theorists Quotes : pic 000352904
Observation always involves theory.
Theorists Quotes : pic 001598716
Our minds are intricate. Our desires are complex. We are gorgeously contradictory in our epistemologies. We were not invented yesterday. Kathleen
Theorists Quotes : pic 001025405
People are experience-rich and theory-poor.
Theorists Quotes : pic 001203250
The theories and speculations of men concern us more than their puny accomplishment. It is with a certain coldness and languor that we loiter about the actual and so-called practical.
Theorists Quotes : pic 001330818
A metaphysician is one who, when you remark that twice two makes four, demands to know what you mean by twice, what by two, what by makes, and what by four. For asking such questions metaphysicians are supported in oriental luxury in the universities, and respected as educated and intelligent men.

Theorists Quotes : pic 000983937
Whoever has the mind stuffed with theories and more theories, suffers horribly because he is unable to realize nothing of what they have read..
Theorists Quotes : pic 000021954
The rhetoric of theory is always in a bind. It pronounces ideas and denounces failures to accept or grasp them while insisting that there are no grounds either for accepting or grasping ideas.
Theorists Quotes : pic 001863355
A theory is no more like a fact than a photograph is like a person.

Theorists Quotes : pic 001116562
I had the most beautiful set of theories you ever knew when I started out as a schoolma'am, but every one of them has failed me at some pinch or another.
Theorists Quotes : pic 001422096
Theories, for me, are just about freeing your mind. It doesn't mean the theory is going to work like a scientific theory works. It's about freeing your mind and making you think a different way.
Theorists Quotes : pic 000834884
Theory is knowledge that doesn't work. Practice is when everything works and you don't know why.
Theorists Quotes : pic 000689213
You are unaware of your theory-in-use. Part of what makes your theory-in-use so powerful is that it operates quickly, skillfully, and effortlessly.
Theorists Quotes : pic 001599948
You make experiments and I make theories. Do you know the difference? A theory is something nobody believes, except the person who made it. An experiment is something everybody believes, except the person who made it.

{Remark to scientist Herman Francis Mark}

Theory is good for the intellect, but action is good for the soul. It's also good for your mental health, your physical health, and your pocketbook.
Theorists Quotes : pic 000711455

Theorists Quotes : pic 000789354
Almost all the other fellows do not look from the facts to the theory but from the theory to the facts; they cannot get out of the network of already accepted concepts; instead, comically, they only wriggle about inside.
Theorists Quotes : pic 000485947
These terrible sociologists, who are the astrologers and alchemists of our twentieth century.
Theorists Quotes : pic 001014812
In chemistry, our theories are crutches; to show that they are valid, they must be used to walk ... A theory established with the help of twenty facts must explain thirty, and lead to the discovery of ten more.

Theorists Quotes : pic 000804080
I write music that sounds complex but isn't. I frankly never think in terms of theory.
Theorists Quotes : pic 000727045

Two polar groups: at one pole we have the literary intellectuals, at the other scientists, and as the most representative, the physical scientists. Between the two a gulf of mutual incomprehension.
Theorists Quotes : pic 000279824

Theorists Quotes : pic 001096475
