In a few decades of reconstruction, even the mathematical natural sciences, the ancient archetypes of theoretical perfection, have changed habit completely! Edmund Husserl
In specific circumstances the period of aging decline can set in earlier in a particular organ than in the organism as a whole which, in a certain general or theoretical sense, is left a cripple or invalid. Wilhelm Ostwald
It is probably safe to say that all the changes of factual knowledge which have led to the relativity theory, resulting in a very great theoretical development, are completely trivial from any point of view except their relevance to the structure of a theoretical system. Talcott Parsons
It is that of increasing knowledge of empirical fact, intimately combined with changing interpretations of this body of fact - hence changing general statements about it - and, not least, a changing a structure of the theoretical system. Talcott Parsons
It was at this moment that I wrote my first important paper in theoretical physics. I was 32 years old, 5 years beyond the alleged age of senility for theorists. Robert B. Laughlin
So instead of talking about theoretical ways of ending the war and violence, I say that we have to get rid of the individual asholes in each office and situation. Colin Quinn
Special emphasis should be laid on this intimate interrelation of general statements about empirical fact with the logical elements and structure of theoretical systems. Talcott Parsons
The amount of detailed information which an individual has at his command and his theoretical elaborations of the same are mutually dependent; they grow in and through each other. Hermann Ebbinghaus
The frontier orbital approach was further developed in various directions by my own group and many other scientists, both theoretical and experimental. Kenichi Fukui
The hypothesis may be put forward, to be tested by the s subsequent investigation, that this development has been in large part a matter of the reciprocal interaction of new factual insights and knowledge on the one hand with changes in the theoretical system on the other. Talcott Parsons
The line of least resistance in the progress of civilization is to make that theoretical postulate real by the continually increasing force of the world's public opinion. Elihu Root
The main concern of the study is with the outline of a theoretical system. Its minor variations from writer to writer are not a matter of concern to this analysis. Talcott Parsons
The methods of theoretical physics should be applicable to all those branches of thought in which the essential features are expressible with numbers. Paul Dirac
The theoretical understanding of the world, which is the aim of philosophy, is not a matter of great practical importance to animals, or to savages, or even to most civilised men. Bertrand Russell
The work requires a moderately large investment in technological and theoretical developments and long periods of time to carry them out, without the pressure to achieve quick or short term results. Aaron Klug
