A Quote by Paul Dirac

A book on the new physics, if not purely descriptive of experimental work, must essentially be mathematical.

Mathematical physics is in the first place physics and it could not exist without experimental investigations.

Peter Debye

Psychology, as the behaviorist views it, is a purely objective, experimental branch of natural science which needs introspection as little as do the sciences of chemistry and physics.... The position is taken here that the behavior of man and the behavior of animals must be considered in the same plane.

John B. Watson

There are a whole other range of sciences that must deal with the narrative reconstruction of the inordinately complex events of history that can occur but once in their detailed glory. And for those kinds of sciences, be it cosmology, or evolutionary biology, or geology, or palaeontology, the experimental methods, simplification, quantification, prediction and repetition of the experimental sciences don't always work. You have to go with the narrative, the descriptive methods of what? Of historians.

Richard Lewontin

To do any important work in physics a very good mathematical ability and aptitude are required. Some work in applications can be done without this, but it will not be very inspired. If you must satisfy your "personal curiosity concerning the mysteries of nature" what will happen if these mysteries turn out to be laws expressed in mathematical terms (as they do turn out to be)? You cannot understand the physical world in any deep or satisfying way without using mathematical reasoning with facility.

Richard P. Feynman

One thing they don't tell you about doing experimental physics is that sometimes you must work under adverse conditions... like a state of sheer terror.

William Kenneth Hartmann

I do not think the division of the subject into two parts - into applied mathematics and experimental physics a good one, for natural philosophy without experiment is merely mathematical exercise, while experiment without mathematics will neither sufficiently discipline the mind or sufficiently extend our knowledge in a subject like physics.

Balfour Stewart

The great problem of today is, how to subject all physical phenomena to dynamical laws. With all the experimental devices, and all the mathematical appliances of this generation, the human mind has been baffled in its attempts to construct a universal science of physics.

Joseph Lovering

It seems that every practitioner of physics has had to wonder at some point why mathematics and physics have come to be so closely entwined. Opinions vary on the answer. ..Bertrand Russell acknowledged..'Physics is mathematical not because we know so much about the physical world, but because we know so little.' ..Mathematics may be indispensable to physics, but it obviously does not constitute physics.

Etienne Klein

The mere formulation of a problem is far more essential than its solution, which may be merely a matter of mathematical or experimental skills. To raise new questions, new possibilities, to regard old problems from a new angle requires creative imagination and marks real advances in science.

Albert Einstein

The emphasis on mathematical methods seems to be shifted more towards combinatorics and set theory - and away from the algorithm of differential equations which dominates mathematical physics.

John von Neumann

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

[On Cantor's work:] The finest product of mathematical genius and one of the supreme achievements of purely intellectual human activity.

David Hilbert

I love to read and teach experimental fiction but yes, neither this work nor my first novel is really that experimental. It uses some experimental techniques but in the end, I would not say that it is experimental. I'm not sure why. I do a lot of writing on my own, and I have always just written this way.

Porochista Khakpour

But in spite of the obvious effectiveness of mathematics in physics, I have never heard of a good a prioriargument that the world must be organised to mathematical principles.

Lee Smolin

Physics was the first of the natural sciences to become fully modern and highly mathematical.Chemistry followed in the wake of physics, but biology, the retarded child, lagged far behind.

Michael Crichton

Now these two questions Does there exist a material reality distinct from sensible appearances? and What is the nature of reality? do not have their source in experimental method, which is acquainted only with sensible appearances and can discover nothing beyond them. The resolution of these questions transcends the methods used by physics; it is the object of metaphysics. Therefore, if the aim of physical theories is to explain experimental laws, theoretical physics is not an autonomous science; it is subordinate to metaphysics.
