Theory Vs Practical Quotes

If you find that youre spending almost all your time on theory, start turning some attention to practical things; it will improve your theories. If you find that youre spending almost all your time on practice, start turning some attention to theoretical things; it will improve your practice.
— Donald Knuth —

Choice Theory explains that, for all practical purposes, we choose everything we do.

— William Glasser

I really detest those people who like to draw practical conclusions from scholarly truths, who 'apply learning to real life', like engineers who turn to propositions of chemistry into insecticides for bedbugs. It translates, in Goethe's words, as: 'life is grey, but the golden tree of theory is always green'.

— Antal Szerb

The Astronomy theory paper on Wednesday morning went well enough. Harry was not convinced he had got the names of all Jupiter's moons right, but was at least confident that none of them was inhabited by mice. They had to wait until evening for their practical Astronomy; the afternoon was devoted instead to Divination.

— J.K. Rowling

In its first 30 years of existence, up to the mid 1970s, the practical applications of game theory were very limited, probably as a result of excessive preoccupation by game theorists with cooperative solution concepts.

— John Harsanyi

I believe what really happens in history is this: the old man is always wrong; and the young people are always wrong about what is wrong with him. The practical form it takes is this: that, while the old man may stand by some stupid custom, the young man always attacks it with some theory that turns out to be equally stupid.

— G.K. Chesterton

There are some people, nevertheless - and I am one of them - who think that the most practical and important thing about a man is still his view of the universe ... We think that for a general about to fight an enemy, it is important to know the enemy's numbers, but still more important to know the enemy's philosophy. We think the question is not whether the theory of the cosmos affects matters, but whether in the long run, anything else affects them.

— G.K. Chesterton

Pfuel was one of those theoreticians who so love their theory that they lose sight of the theory's object-its practical application. His love of theory made him hate everything practical, and he would not listen to it. He was even pleased by failures, for failures resulting from deviations in practice from the theory only proved to him the accuracy of his theory.

— Leo Tolstoy

His [Thomas Edison] method was inefficient in the extreme, for an immense ground had to be covered to get anything at all unless blind chance intervened and, at first, I was almost a sorry witness of his doings, knowing that just a little theory and calculation would have saved him 90 per cent of the labor. But he had a veritable contempt for book learning and mathematical knowledge, trusting himself entirely to his inventor's instinct and practical American sense. In view of this, the truly prodigious amount of his actual accomplishments is little short of a miracle.

— Nikola Tesla

Nothing is more practical than a good theory.

— Ludwig Boltzmann

The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation.

— Paul Dirac

The triumph of science has been mainly due to its practical utility, and there has been an attempt to divorce this aspect from that of theory, thus making science more and more a technique, and less and less a doctrine as to the nature of the world. The penetration of this point of view to philosophers is very recent.

— Bertrand Russell

I do not think much of the good luck theory of self-made men. It is worth but little attention and has no practical value.

— Frederick Douglass

All social life is essentially practical. All mysterious which lead theory to mysticism find their rational solution in human practice and in the comprehension of the practice.

— Karl Marx
