Physicist Quotes - page 3
Boscovich's ideas exerted a deep influence on the work on the next following generation of physicist ... Our esteem for the purposefulness of Boscovich's great scientific work, and the inspiration behind it, increases the more as we realize the sctent to which it served to pave the way for the later developments.
Roger Joseph Boscovich
There are street artists. Street musicians. Street actors. But there are no street physicists. A little known secret is that a physicist is one of the most employable people in the marketplace - a physicist is a trained problem solver. How many times have you heard a person in a workplace say, "I wasn't trained for this!" That's an impossible reaction from a physicist, who would say, instead, "Cool. A problem I've never seen before. Let's see how I can figure out how to solve it!"
Neil deGrasse Tyson
There you have, then, a theoretical physics which is neither the theory of a believer nor that of a nonbeliever, but merely and simply a theory of a physicist; admirably suited to classify the laws studied by the experimenter, it is incapable of opposing any assertion whatever of metaphysics or of religious dogma, and is equally incapable of lending effective support to any such assertion.
Pierre Duhem
Surely, after 62 years, we should have an exact formulation of some serious part of quantum mechanics? By 'exact' I do not of course mean 'exactly true'. I mean only that the theory should be fully formulated in mathematical terms, with nothing left to the discretion of the theoretical physicist... until workable approximations are needed in applications. By 'serious' I mean that some substantial fragment of physics should be covered. Nonrelativistic 'particle' quantum mechanics, perhaps with the inclusion of the electromagnetic field and a cut-off interaction, is serious enough.
John Stewart Bell
The physicist needs a facility in looking at problems from several points of view. The exact analysis of real physical problems is usually quite complicated, and any particular physical situation may be too complicated to analyze directly by solving the differential equation. But one can still get a very good idea of the behavior of a system if one has some feel for the character of the solution in different circumstances. Ideas such as the field lines, capacitance, resistance, and inductance are, for such purposes, very useful. ... On the other hand, none of the heuristic models, such as field lines, is really adequate and accurate for all situations. There is only one precise way of presenting the laws, and that is by means of differential equations. They have the advantage of being fundamental and, so far as we know, precise. If you have learned the differential equations you can always go back to them. There is nothing to unlearn.
Richard Feynman
I was reminded of a quotation by the famous American physicist Steven Weinberg, Nobel Prize-winning theoretical physicist. Weinberg said: "Religion is an insult to human dignity. Without it, you'd have good people doing good things, and evil people doing evil things. But for good people to do evil things, it takes religion."
Richard Dawkins
Maxwell's equations... originally consisted of eight equations. These equations are not "beautiful." They do not possess much symmetry. In their original form, they are ugly.... However, when rewritten using time as the fourth dimension, this rather awkward set of eight equations collapses into a single tensor equation. This is what a physicist calls "beauty," because both criteria are now satisfied.
Michio Kaku
He was one of the few judges who could occasionally poke fun at himself. He told me that once he was sitting at a dinner at the Cambridge University where a number of distinguished persons had been invited. Next to him was an elderly gentleman whose identity he did not know. There was some discussion about the theory of relativity and he aired his own views with a certain measure of authority. His neighbour told him that his views were interesting and invited him for a cup of tea in the next two or three days. Later on he found out that he had been talking to the world renowned physicist Sir Arthur Eddington who was reputed as one of the few persons apart from Einstein who understood the theory of relativity. He never picked up the courage to go for that cup of tea and face Sir Arthur Eddington.

When the physicist poses the question, "What does it mean to do physics?" or "What is research in physics?" - his question is a preliminary question. Clearly, when you ask a question like that, and try to answer it, you are not "doing physics." Or rather you are no longer doing physics. But when you ask yourself, "What does it mean to do philosophy?" then you actually are "doing philosophy" - this is not at all a "preliminary" question but a truly philosophical one: you are right at the heart of the business.
