At any one time there is a natural tendency among physicists to believe that we already know the essential ingredients of a comprehensive theory. But each time a new frontier of observation is broached we inevitably discover new phenomena which force us to modify substantially our previous conceptions. I believe this process to be unending, that the delights and challenges of unexpected discovery will continue always.
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
... still many physicists are convinced to "see" the particle in a cloud chamber or on a scintillation screen, therefore accepting classical particle coordinates as pieces of reality. But what one concludes to see depends on the chosen model of reality, and this model can only be judged by its success in consistently and economically describing the observations (therefore interpolating between them).h. dieter zeh
I decided to get Ph.D. in experimental physics because experimental physicists have their own room in the Institute where they can hang their coat, whereas theoretical physicists have to hang their coat at the entrance.george gamow
I am obliged to interpolate some remarks on a very difficult subject: proof and its importance in mathematics. All physicists, and a good many quite respectable mathematicians, are contemptuous about proof. I have heard Professor Eddington, for example, maintain that proof, as pure mathematicians understand it, is really quite uninteresting and unimportant, and that no one who is really certain that he has found something good should waste his time looking for proof.g. h. hardy
Despite the vision and farseeing wisdom of our wartime heads of state, the physicists have felt the peculiarly intimate responsibility for suggesting, for supporting, and in the end, in large measure, for achieving the realization of atomic weapons. Nor can we forget that these weapons as they were in fact used dramatized so mercilessly the inhumanity and evil of modern war. In some sort of crude sense which no vulgarity, no humor, no overstatement can quite extinguish, the physicists have known sin; and this is a knowledge which they cannot lose.j. robert oppenheimer
The mathematicians know a great deal about very little and the physicists very little about a great deal.stanislaw ulam
Our relationships as experimentalists with theoretical physicists should be like those with a beautiful woman – we should accept with gratitude any favours she offers, but we should not expect too much nor believe all that is said.lev artsimovich
Theoretical physicists live in a classical world, looking out into a quantum-mechanical world. The latter we describe only subjectively, in terms of procedures and results in our classical domain.john stewart bell
For those who want some proof that physicists are human, the proof is in the idiocy of all the different units which they use for measuring energy .richard feynman
While in the ?rst quarter of this century physicists and cosmologists were forced to revise the basic notions that govern the natural sciences, in the last quarter of this century biologists will force a revision of the basic notions that govern science itself. After that “?rst revolution” it was clear that the classical concept of an “ultimate science”, that is an objective description of the world in which there are no subjects (a “subjectless universe”), contains contradictions.heinz von foerster
Physics is too difficult for physicists!david hilbert
Today, like the elusive planet Vulcan in the nineteenth century, dark matter is accepted by the majority of astronomers and physicists as actually existing. Dark matter, although it has never been seen, is part of the generally accepted standard model of physics and cosmology, which also includes the big bang beginning of the universe.john moffat
To physicists such as myself, the huge amount of invisible dark matter needed to make Einstein's theory fit the astrophysical data is reason enough for exploring modified gravity theories.john moffat

It has now become clear that the exploration of the Universe, as conducted by physicists, astronomers and cosmologists, is one of the greatest intellectual adventures of the mid-twentieth century.dennis sciama
It is true that physicists hope to look behind the ‘big bang,’ and possibly to explain the origin of our universe as, for example, a type of fluctuation. But then, of what is it a fluctuation and how did this in turn begin to exist? In my view, the question of origin seems always left unanswered if we explore from a scientific view alone.

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.

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.
We must be physicists in order to be creative since so far codes of values and ideals have been constructed in ignorance of physics or even in contradiction to physics.friedrich nietzsche
Physics is, hopefully, simple. physicists are not.Edward Teller
physicists continue to debate whether Bell's theorem is airtight or not. However, the real question is not whether Bell can prove beyond doubt that reality is non-local, but whether the world is in fact non-local.
physicists use the wave theory on Mondays, Wednesdays and Fridays and the particle theory on Tuesdays, Thursdays and Saturdays
