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].
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
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
The Physics of motion provides one of the clearest examples of the counter-intuitive and unexpected nature of science.Lewis Wolpert
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.
That is simple my friend: because politics is more difficult than Physics.Albert Einstein
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
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.
Our understanding of the four basic concepts of Physics -- space, time, matter and force -- has undergone radical change in the course of work on unification, starting with Maxwell's unification of electricity with magnetism, all the way to present day string theory. What started as four independent concepts, with space and time postulated and the possible forms of matter and force arbitrarily chosen, now appear as different aspects of a rich and novel dynamically determined structure.peter freund
The atomic hypothesis which had worked so splendidly in Physics breaks down in Psychics.john maynard keynes
Physics is mathematical not because we know so much about the physical world, but because we know so little: it is only its mathematical properties that we can discover.bertrand russell
It is now quite lawful for a Catholic woman to avoid pregnancy by a resort to mathematics, though she is still forbidden to resort to Physics and chemistry.'Minority Report'. Collected in Notebooks (1956).
Quantum Physics is no longer an abstract theory for specialists. We must now absolutely include it in our education and also in our culture.claude cohen-tannoudji
Good Physics can be done if we have a good shop. ... Given a good shop and good measurement equipment a sound physicist can do wonderful work.w. w. hansen
I think that modern Physics has definitely decided in favor of Plato. In fact the smallest units of matter are not physical objects in the ordinary sense; they are forms, ideas which can be expressed unambiguously only in mathematical language.werner heisenberg
I can't think that it would be terrible of me to say — and it is occasionally true — that I need Physics more than friends.j. robert oppenheimer
Chemistry has been termed by the physicist as the messy part of Physics, but that is no reason why the physicists should be permitted to make a mess of chemistry when they invade it.frederick soddy
...the ultimate objective of teaching Physics is promoting a sound physical thinking and not merely tackling a list of topics.On the Reform of Physics Education delivered 1912 at a general assembly of the Hungarian National Society of Secondary School Teachers.
There is nothing new to be discovered in Physics now; All that remains is more and more precise measurement.Lord Kelvin, allegedly speaking to the w:British Association for the Advancement of Science in 1900. The veracity of this attribution is disputed, and no contemporaneous documentation of the statement is known.
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
It is important to realize that in Physics today, we have no knowledge what energy is . We do not have a picture that energy comes in little blobs of a definite amount. It is not that way.richard feynman
The best that most of us can hope to achieve in Physics is simply to misunderstand at a deeper level.wolfgang pauli
Changi became my university instead of my prison. ... Among the inmates there were experts in all walks of life the high and the low roads. I studied and absorbed everything I could from Physics to counterfeiting, but most of all I learned the art of surviving.James Clavell, as quoted in "James Clavell, Best-Selling Storyteller of Far Eastern Epics, Is Dead at 69" by William Grimes in The New York Times (8 September 1994)
The most powerful influence exercised by the Arabs on general natural Physics was that directed to the advances of chemistry; a science for which this race created a new era.(...) Besides making laudatory mention of that which we owe to the natural science of the Arabs in both the terrestrial and celestial spheres, we must likewise allude to their contributions in separate paths of intellectual development to the general mass of mathematical science.alexander von humboldt
[An] example of the hubris of contemporary science is the rigorous banishment of the word "purpose" from its vocabulary. This is probably an aftermath of the reaction against the animism of Aristotelian Physics, where stones accelerated their fall because of their impatience to get home, and against a teleological world-view in which the purpose of the stars was to serve as chronometers for man's profit. From Galileo onward, "final causes" were relegated into the realm of superstition, mechanical causality reigned supreme. ...The mechanistic universe gradually disintegrated, but the mechanistic notion of causality survived until Heisenberg's indeterminacy principle proved its untenability.Arthur Koestler
It is important to realize that in Physics today, we have no knowledge what energy is . We do not have a picture that energy comes in little blobs of a definite amount.Richard Feynman, in The Feynman Lectures on Physics (1964) Volume I, 4-1
Mathematics is not something that you find lying around in your back yard. It’s produced by the human mind. Yet if we ask where mathematics works best, it is in areas like particle Physics and astroPhysics, areas of fundamental science that are very, very far removed from everyday affairs.Paul Davies, How Unique You Are!; Is There a Creator Who Cares About You?, published by Jehovah's Witnesses.
