Theory Quotes
-
Social cognitive theory rejects the dichotomous conception of self as agent and self as object. Acting on the environment and acting on oneself entail shifting the perspective of the same agent rather than reifying different selves regulating each other or transforming the self from agent to object.
Albert Bandura
-
A correct theory is the first step towards improvement, by showing what we need and what we might accomplish.
William Stanley Jevons
-
When you have two competing theories that make exactly the same predictions, the simpler one is the better.
William of Occam
-
The whole theory of modern education is radically unsound. Fortunately in England, at any rate, education produces no effect whatsoever. If it did, it would prove a serious danger to the upper classes, and probably lead to acts of violence.
Oscar Wilde
-
However we select from nature a complex of phenomena using the criterion of simplicity, in no case will its theoretical treatment turn out to be forever appropriate (sufficient).... I do not doubt that the day will come when general relativity, too, will have to yield to another one, for reasons which at present we do not yet surmise. I believe that this process of deepening theory has no limits.
Albert Einstein
-
Whether you can observe a thing or not depends on the theory which you use. It is the theory which decides what can be observed.
Albert Einstein
-
The scientific theorist is not to be envied. For Nature, or more precisely experiment, is an exorable and not very friendly judge of his work. It never says "yes" to a theory. In the most favorable cases it says "Maybe," and in the great majority of cases simply "No." If an experiment agrees with a theory it means for the latter "Maybe," and if it does not agree it means "No." Probably every theory will some day experience its "No" - most theories, soon after conception.
Albert Einstein
-
Backlock, a poet blind from his birth, could describe visual objects with accuracy; Professor Sanderson, who was also blind, gave excellent lectures on color, and taught others the theory of ideas which they had and he had not. In the social sphere these gifted ones are mostly women; they can watch a world which they never saw, and estimate forces of which they have only heard. We call it intuition.
Thomas Hardy
-
A theory is something nobody believes, except the person who made it. An experiment is something everybody believes, except the person who made it.
Albert Einstein
-
Theory regards this opening as incorrect, but it is impossible to agree with this. Out of the five tournament games played by me with the King's Gambit, I have won all five.
David Bronstein
-
We're going to need a definitive quantum theory of gravity, which is part of a grand unified theory - it's the main missing piece.
Kip Thorne
-
Behavior is the theory of manners practically applied.
Bill Vaughan
-
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.
Nicolaus Copernicus
-
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
-
The gospel of Jesus is not a rational concept to be explained in a theory of salvation, but a story about God’s presence in Jesus’ solidarity with the oppressed, which led to his death on the cross. What is redemptive is the faith that God snatches victory out of defeat, life out of death, and hope out of despair.
James Hal Cone
-
On quantum theory I use up more brain grease than on relativity.
Albert Einstein
