Once we see, however, that the probability of life originating at random is so utterly miniscule as to make it absurd, it becomes sensible to think that the favorable properties of physics on which life depends are in every respect deliberate ... . It is therefore almost inevitable that our own measure of intelligence must reflect ... higher intelligences ... even to the limit of God ... such a theory is so obvious that one wonders why it is not widely accepted as being self-evident. The reasons are psychological rather than scientific.
We do not aim at « mathematical rigour » of exposition, which in theoretical Physics often amounts to self-deception."Quantum Mechanics: Non-relativistic Theory", together with L. D. Landau, translated by John Menzies (third edition 1991), p. xi
It is to be emphasized that no matter how many [amplitude] arrows we draw, add, or multiply, our objective is to calculate a single final arrow for the event . Mistakes are often made by Physics students at first because they do not keep this important point in mind. They work for so long analyzing events involving a single photon that they begin to think that the arrow is somehow associated with the photon [rather than with the event].richard feynman
Doing Physics is much more enjoyable than just learning it. Maybe 'doing it' is the right way of learning, at least as far as I am concerned.in his Nobel biography, edited by Tore Frängsmyr, Gösta Ekspong, Nobelstiftelsen (1993). Physics 1981-1990. World Scientific. p. 383. ISBN 9810207298.
On the contrary, it's because somebody knows something about it that we can't talk about Physics . It's the things that nobody knows anything about that we can discuss. We can talk about the weather; we can talk about social problems; we can talk about psychology; we can talk about international finance gold transfers we can't talk about, because those are understood so it's the subject that nobody knows anything about that we can all talk about!richard feynman
At present, when the prevailing forms of society have become hindrances to the free expression of human powers, it is precisely the abstract branches of science, mathematics and theoretical Physics, which ... offer a less distorted form of knowledge than other branches of science which are interwoven with the pattern of daily life, and the practicality of which seemingly testifies to their realistic character.max horkheimer
Pragmatism, in trying to turn experimental Physics into a prototype of all science and to model all spheres of intellectual life after the techniques of the laboratory, is the counterpart of modern industrialism, for which the factory is the prototype of human existence, and which models all branches of culture after production on the conveyor belt.max horkheimer
I think of Physics as the liberal arts of technology . You understand the fundamental aspects of Physics, and then you can learn the technology and understand how it relates to current world problems. I'm teaching the elementary Physics that is most useful for someone who is trying to live in a technological world, to contribute to that world, and to make correct decisions.Richard A. Muller as quoted by Devi Mathieu, in Physicist Richard Muller helps prepare tomorrow’s leaders for a technological world, The Berkeleyan, 26 February 2003.
?Machines which do not receive their motion from heat... can be studied even to their smallest details by the mechanical theory. ...A similar theory is evidently needed for heat-engines. We shall have it only when the laws of Physics shall be extended enough, generalized enough, to make known beforehand all of the effects of heat acting in a determined manner on any body.Nicolas Léonard Sadi Carnot, Reflections on the Motive Power of Heat and on Machines Fitted to Develop Power (1824)
Mathematical Physics is in the first place Physics and it could not exist without experimental investigations.Inaugural lecture for his professorship of mathematical physics at the University of Utrecht (1913), as quoted by Davies, Mansel. Peter Joseph Wilhelm Debye: 1884-1966. Biographical Memoirs of Fellows of The Royal Society, Vol. 16 (1970).
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
Hypothesis Of Molecular Vortices. In thermodynamics as well as in other branches of molecular Physics, the laws of phenomena have to a certain extent been anticipated, and their investigation facilitated, by the aid of hypotheses as to occult molecular structures and motions with which such phenomena are assumed to be connected. The hypothesis which has answered that purpose in the case of thermodynamics, is called that of "molecular vortices," or otherwise, the "centrifugal theory of elasticity. (On this subject, see the Edinburgh Philosophical Journal, 1849; Edinburgh Transactions, vol. xx.; and Philosophical Magazine, passim, especially for December, 1851, and November and December, 1855.)william john macquorn rankine
For all the sublimity of art, Physics, music, mathematics, and other manifestations of human genius, everything depends on the mundane, frustrating, often debased vocation known as politics (and its most exacting subspecialty – statecraft). Because if we don't get politics right, everything else risks extinction.charles krauthammer
The recognition of certain basic impossibilities has laid the foundations of some major principles of Physics and chemistry; similarly, recognition of the impossibility of understanding living things in terms of Physics and chemistry, far from setting limits to our understanding of life, will guide it in the right direction. And even if the demonstration of this impossibility should prove of no great advantage in the pursuit of discovery, such a demonstration would help to draw a truer image of life and man than that given us by the present basic concepts of biology.Michael Polanyi (1968) Life's irreducible structure
If Physics leads us today to a world view which is essentially mystical , it returns, in a way, to its beginning, 2,500 years ago. [...] This time, however, it is not only based on intuition, but also on experiments of great precision and sophistication, and on a rigorous and consistent mathematical formalism.Fritjof Capra (1975) The Tao of Physics. Ch. 1, Modern Physics, p. 19
Mathematical Physics represents the purest image that the view of nature may generate in the human mind; this image presents all the character of the product of art; it begets some unity, it is true and has the quality of sublimity; this image is to physical nature what music is to the thousand noises of which the air is full...Théophile de Donder as quoted by Ilya Prigogine in his Autobiography given at the occasion of Prigogine's 1977 Nobel Prize in Chemistry.
If one looks at the different problems of the integral calculus which arise naturally when one wishes to go deep into the different parts of Physics , it is impossible not to be struck by the analogies existing.Henri Poincare, in Popular Science Mar (1913)., p.215
