We do not aim at « mathematical rigour » of exposition, which in theoretical physics often amounts to self-deception.
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.fred hoyle
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
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
I regard Physics as that subset of magic that works fairly reliably. I regard magick, in the traditional sense, as a kind of Physics that we strive to understand and render more reliable. So it all comes down to the same thing, a quest to understand and manipulate the world with a self-consistent and coherent theory .peter j. carroll
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
Philosophy treats of Physics where a more careful knowledge is required because the problems which come under this head are numerous... So the reader of Ctesibius or Archimedes and the other writers of treatises of the same class will not be able to appreciate them unless he has been trained in these subjects by the philosophers.vitruvius
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
While the new Physics was developing in the twentieth century, the mechanistic Cartesian world view and the principles of Newtonian Physics maintained their strong influence on Western scientific thinking, and even today many scientists still hold to the mechanistic paradigm, although physicists themselves have gone beyond it.Fritjof Capra (1975) The Tao of Physics. p. 93
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
