Physics is at present a mass of partial theories which no man has yet been able to render truly and clearly consistent. It has been well said that the modern physicist is a quantum theorist on Monday, Wednesday, and Friday and a student of gravitational relativity theory on Tuesday, Thursday, and Saturday. On Sunday he is praying. . . that someone will find the reconciliation between the two views.Norbert Wiener
Physics and philosophy are at most a few thousand years old, but probably have lives of thousands of millions of years stretching away in front of them. They are only just beginning to get under way.James Jeans (1942) Physics and Philosophy, p. 217.
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.
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...as quoted by Ilya Prigogine in his Autobiography given at the occasion of Prigogine's 1977 Nobel Prize in Chemistry.
This elegant generalization is mathematically very appealing; but Physics means facing facts. You should take up case by case.One should not value elegant math above physical facts. As quoted by Sundaram, R. (December 10 1998). "K. S. Krishnan—the complete physicist". Current Science 75 (11): 1263-1265.
The beauty of Physics lies in the extent to which seemingly complex and unrelated phenomena can be explained and correlated through a high level of abstraction by a set of laws which are amazing in their simplicity.in Electromagnetism and Its Relation to Relativity, chapter 3 of his book Principles of electrodynamics. Courier Dover Publications. 1987. p. 105. ISBN 0486654931.
Is the purpose of theoretical Physics to be no more than a cataloging of all the things that can happen when particles interact with each other and seperate? Or is it to be an understanding at a deeper level in which there are things that are not directly observable (as the underlying quantized fields are) but in terms of which we shall have a more fundamental understanding?julian schwinger
If Physics is too difficult for the physicists, the nonphysicist may wonder whether he should try at all to grasp its complexities and ambiguities. It is undeniably an effort, but probably one worth making, for the basic questions are important and the new experimental results are often fascinating. And if the layman runs into serious perplexities, he can be consoled with the thought that the points which baffle him are more than likely the ones for which the professionals have not found satisfactory answers.edward condon
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
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
Whenever I teach my semiconductor device Physics course, one of the central messages I try to get across early is the importance of energy band diagrams. I often put this in the form of "Kroemer's Lemma of Proven Igorance": If, in discussing a semiconductor problem, you cannot draw an Energy Band Diagram, this shows that you don't know what you are talking about, with the corollary If you can draw one, but don't, then your audience won't know what you are talking about.herbert kroemer
The new coherent picture is not yet available. With all their immense empirical success, G(eneral)R(elativity) and Q(uantum)M(echanics) have left us with an understanding of the physical world which is unclear and badly fragmented. At the foundations of Physics there is today confusion and incoherence.carlo rovelli
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
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.
Somehow, the practice of astronomy, Physics, chemistry or biology normally fails to evoke the controversies over fundamentals that today seem endemic among, say, psychologists or sociologists. Attempting to discover the source of that difference led me to recognize the role in scientific research of what I have since called “paradigms.” These I take to be universally recognized scientific achievements that for a time provide model problems and solutions for a community of practitioners.Thomas Samuel Kuhn (1962) The Structure of Scientific Revolutions. p.48
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
With regard to this question modern Physics takes a definite stand against the materialism of Democritus and for Plato and the Pythagoreans . The elementary particles are certainly not eternal and indestructible units of matter, they can actually be transformed into each other. ... The elementary particles in Plato's Timaeus are finally not substance but mathematical forms.werner heisenberg
Following Korzybski , I put things in probabilities, not absolutes... My only originality lies in applying this zetetic attitude outside the hardest of the hard sciences, Physics, to softer sciences and then to non-sciences like politics, ideology, jury verdicts and, of course, conspiracy theory.Robert Anton Wilson, in an interview in High Times (2003)
I tend to approach things from a Physics framework. And Physics teaches you to reason from first principles rather than by analogy.Elon Musk, in Elon Musk’s Mission to Mars (21 October 2012)
