[A] skyhook is ... an exception to the principle that all design, and apparent design, is ultimately the result of mindless, motiveless mechanicity. A crane, in contrast, is a subprocess or special feature of a design process that can be demonstrated to permit the local speeding up of the basic, slow process of natural selection, and that can be demonstrated to be itself the predictable (or retroactively explicable) product of the basic process. ... [T]he physicist Steven Weinberg, in Dreams of a Final Theory (1992) ... distinguishes between uncompromising reductionism (a bad thing) and compromising reductionism (which he ringingly endorses). Here is my own version. We must distinguish reductionism, which is in general a good thing, from greedy reductionism, which is not. The difference, in the context of Darwin's theory, is simple: greedy reductionists think that everything can be explained without cranes; good reductionists think that everything can be explained without skyhooks. (Daniel Dennett)
A Swedish physicist can not discuss his work with fifty people unless he goes abroad. A Swedish economist can get opinions and instructions in his native language from thousands upon thousands of his fellow citizens. View quote
George Stigler
Mankind has moved away from the heart of the world to the logic of the mind, and their belief is in the chemist, the physicist, and the mathematician. Science has proven to them that all this ancient belief in ceremony is simply ignorance. View quote
Drunvalo Melchizedek
My first degree came years before my second. I had wanted to be a physicist, but I flunked calculus. View quote
Elizabeth Moon
I wanted to become a mathematician, physicist or astronomer. View quote
Philip Emeagwali
Many applications of the coincidence method will therefore be found in the large field of nuclear physics, and we can say without exaggeration that the method is one of the essential tools of the modern nuclear physicist. View quote
Walther Bothe
Every physicist (naturally, this equally applies to other specialities, but I re- strict myself to physicists for definitiveness) should simultaneously know, apart from theoretical physics, a wealth of facts from different branches of physics and be familiar with the newest notable accomplishments.

Vitaly Ginzburg
I have seen the astrolabe called Zuraqi invented by Abu Sa'id Sijzi. I liked it very much and praised him a great deal, as it is based on the idea entertained by some to the effect that the motion we see is due to the Earth's movement and not to that of the sky. By my life, it is a problem difficult of solution and refutation. [...] For it is the same whether you take it that the Earth is in motion or the sky. For, in both cases, it does not affect the Astronomical Science. It is just for the physicist to see if it is possible to refute it. View quote
Al-Biruni
While it is never safe to affirm that the future of Physical Science has no marvels in store even more astonishing than those of the past, it seems probable that most of the grand underlying principles have been firmly established and that further advances are to be sought chiefly in the rigorous application of these principles to all the phenomena which come under our notice. It is here that the science of measurement shows its importance - where quantitative work is more to be desired than qualitative work. An eminent physicist remarked that the future truths of physical science are to be looked for in the sixth place of decimals. View quote
Albert Abraham Michelson
No one gets angry at a mathematician or a physicist whom he or she doesn't understand at all, or at someone who speaks a foreign language, but rather at someone who tampers with your own language, with this 'relation,' precisely, which is yours. View quote
Jacques Derrida
The social sciences building at the University of Chicago indeed still bears since it was built 40 years ago on its outside an inscription taken from the famous physicist Lord Kelvin: "When you cannot measure, your knowledge is meager and unsatisfactory." I will admit that that may be true, but it is certainly not scientific to insist on measurement where you don't know what your measurements mean. There are cases where measurements are not relevant. What has done much damage to microeconomics is striving for a pseudo-exactness by imitating methods of the physical sciences which have to deal with what are fundamentally much more simple phenomena. And the assumption that it is possible to ascertain all the relevant particular facts still completely dominates the alternative methods of dealing with our constitutional ignorance, which economists have tried to overcome. This of course, is what has come to be called macroeconomics as distinct from microeconomics. (Friedrich Hayek)
The word model is used as a noun, adjective, and verb, and in each instance it has a slightly different connotation. As a noun "model" is a representation in the sense in which an architect constructs a small-scale model of a building or a physicist a large-scale model of an atom. As an adjective "model" implies a degree or perfection or idealization, as in reference to a model home, a model student, or a model husband. As a verb "to model" means to demonstrate, to reveal, to show what a thing is like. View quote
Russell L. Ackoff
By asserting the objectivity of the physical world, naturalism identifies the existence and the conditions of existence of the physical world with existence and the conditions of existence in general. It forgets that the world of the physicist necessarily refers back, through its intrinsic meaning, through the subjective world which one tries to exclude from reality as being pure appearance, conditioned by the empirical nature of man, which is incapable of reaching directly to a world of things in themselves. But while the world of the physicist claims to go beyond naive experience, his world really exists only in relation to naive experience. View quote
Emmanuel Levinas
Physics is becoming so unbelievably complex that it is taking longer and longer to train a physicist. It is taking so long, in fact, to train a physicist to the place where he understands the nature of physical problems that he is already too old to solve them. View quote
E. P. Wigner
As a theoretical physicist, I feel at once proud and humble at the thought of the illustrious figures that have preceded me here to receive the greatest of all honors in science, the Nobel prize. View quote
Murray Gell-Mann
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. View quote
Norbert Wiener
The politics of reality,” Shevek repeated. He looked at Oiie and said, "That is a curious phrase for a physicist to use.” "Not at all. The politician and the physicist both deal with things as they are, with real forces, the basic laws of the world.” "You put your petty miserable ‘laws' to protect wealth, your ‘forces' of guns and bombs, in the same sentence with the law of entropy and the force of gravity? I had thought better of your mind, Demaere! View quote
Ursula K. Le Guin
...there is probably less difference between the positions of a mathematician and of a physicist than is generally supposed, [...] the mathematician is in much more direct contact with reality. This may seem a paradox, since it is the physicist who deals with the subject-matter usually described as ‘real', but [...] [a physicist] is trying to correlate the incoherent body of crude fact confronting him with some definite and orderly scheme of abstract relations, the kind of scheme he can borrow only from mathematics. View quote
G. H. Hardy
I went into physics to hang around with the bright kids. I wasn't doing anything else and I didn't want to look dumb, so I thought I'd pretend to be a physicist, just like the others. It was five or ten years after my Ph. D. before I realized I was pretty good. View quote
Leon M. Lederman
I don't think that any physicist would have been clever enough to have invented string theory on purpose... Luckily, it was invented by accident. View quote
Edward Witten
It is difficult for the matter-of-fact physicist to accept the view that the substratum of everything is of mental character. But no one can deny that mind is the first and most direct thing in our experience, and all else is remote inference - inference either intuitive or deliberate. (Arthur Eddington)
If to-day you ask a physicist what he has finally made out the æther or the electron to be, the answer will not be a description in terms of billiard balls or fly-wheels or anything concrete; he will point instead to a number of symbols and a set of mathematical equations which they satisfy. What do the symbols stand for? The mysterious reply is given that physics is indifferent to that; it has no means of probing beneath the symbolism. To understand the phenomena of the physical world it is necessary to know the equations which the symbols obey but not the nature of that which is being symbolised. ... this newer outlook has modified the challenge from the material to the spiritual world.

Arthur Eddington
[Experimental Physicist] Phys. I cannot imagine myself perceiving non-Euclidean space! Math. Look at the reflection of the room in a polished doorknob, and imagine yourself one of the actors in what you see going on there. View quote
Arthur Eddington
Our environment may and should mean something towards us which is not to be measured with the tools of the physicist or described by the metrical symbols of the mathematician. View quote
Arthur Eddington
Physical science comes nearest to that complete system of exact knowledge which all sciences have before them as an ideal. Some fall far short of it. The physicist who inveighs against the lack of coherence and the indefiniteness of theological theories, will probably speak not much less harshly of the theories of biology and psychology. They also fail to come up to his standard of methodology. On the other side of him stands an even superior being - the pure mathematician - who has no high opinion of the methods of deduction used in physics, and does not hide his disapproval of the laxity of what is accepted as proof in physical science. And yet somehow knowledge grows in all these branches. Wherever a way opens we are impelled to seek by the only methods that can be devised for that particular opening, not over-rating the security of our finding, but conscious that in this activity of mind we are obeying the light that is in our nature.
