  Mathematical Physics - Wikipedia, the free encyclopedia
Mathematical physics is the scientific discipline concerned with "the application of mathematics to problems in physics and the development of mathematical methods suitable for such applications and for the formulation of physical theories"
Revolutionary mathematical physicists at the turn of the 20th century included the mathematician David Hilbert who devised the theory of Hilbert spaces for integral equations which would find a major application in quantum mechanics.
The term 'mathematical' physics is also sometimes used in a special sense, to distinguish research aimed at studying and solving problems inspired by physics within a mathematically rigorous framework.

Most contributors, however, begin with mathematical, historical and sociological considerations that also include the prospective effects of new ways of communication and publishing, which might threaten mathematical rigour. Yet a philosophical analysis of the debate and a classification of the various opinions is still lacking.
But if mathematics is to rejuvenate itself and break new ground it will have to allow for the exploration of new ideas and techniques which, in their creative phase, are likely to be dubious as in some of the great eras of the past.
Indeed mathematics is acquitted of one important element of physical theory, to wit, the approximation of physical facts by a mathematical model.

Mathematical physicist Roger Penrose, on the nature of physical theory: "It is clear that a great deal has been learnt, and also that we should not be too complacent that the pictures that we have formed at any one time are not to be overturned by some later and deeper view."
Other physicists tend to think that a pre-existing 'independence' of the laws is speculative, is in fact beyond the purvey of science, and describe the laws as having been initiated at the time of the bang, perhaps prescribed by some mysterious aspect of the so-called "superforce" of Grand Unification Theory.
Some physicists believe that a concise and complete description of the physical universe is "the end of physics" and "the ultimate triumph of the human intellect" and that such a description is possible, even near.

 Towards a philosophy of real mathematics
In this ambitious study, David Corfield attacks the widely held view that it is the nature of mathematical knowledge which has shaped the way in which mathematics is treated philosophically, and claims that contingent factors have brought us to the present thematically limited discipline.
In other words there is just "one" mathematical world, whose exploration is the task of all mathematicians and they are all in the same boat somehow.

Rather there is mathematics and there is physics, and their cyclical relationship enjoys periods of cooperation interspersed with periods of mutual indifference.
We invited physicists who were working on soliton-instanton questions, and we listened to Atiyah explain how his index theorem with Singer counts instanton zero modes, and how their spectral-flow theorem with V. Patodi is relevant to Fractional charge.
For example, physicists wanted very much to combine internal and spacetime symmetries in a nontrivial fashion and were not daunted by a proven "impossibility theorem." Rather the "theorem" was circumvented by the simple device of replacing commutators with anticommutators and by grading the algebra.

 Science News Magazine Editor's Picks - The Stability of Matter
Freeman J. Dyson, a mathematical physicist at the Institute for Advanced Study in Princeton, N.J., became enchanted with the question.
He and physicist Walter Thirring of the University of Vienna found a simpler proof of matter's stability than the one put forth by Dyson and Lenard, using mathematical techniques that relied more heavily on physical intuition.
Moreover, by clarifying mathematically the conditions under which matter does remain stable, Lieb and his colleagues may help to shed light on those in which it doesn't, such as the conditions believed to be present in stars headed for collapse and explosion.

He is also the founder of mathematical intuitionism, and a key player in the debate on foundations of mathematics that raged for a brief decade in the 1920s, and then subsided.
But so prevalent within their mathematical training was the dismissal of this debate as a dead end in the philosophy of mathematics that they, too, subscribed to the prevailing wisdom that it was a non-issue, a cul-de-sac not worth exploring.
The separation between mathematics and mathematical language is the first of the two "acts" in the development of intuitionism.

 AMS Prize - Leonard Eisenbud Prize for Mathematics and Physics
This prize was established in 2006 in memory of the mathematical physicist, Leonard Eisenbud (1913-2004), by his son and daughter-in-law, David and Monika Eisenbud.
In later years he became interested in the foundations of quantum mechanics and in the interaction of physics with culture and politics, teaching courses on the anti-science movement.
Thus, for example, the prize might be given for a contribution to mathematics inspired by modern developments in physics or for the development of a physical theory exploiting modern mathematics in a novel way.

Thus in his essay Faddeev, who has considered himself a mathematical physicist for 40 years, regards mathematical physics as a subject that grew out of what was called theoretical physics 100 years ago, but became more mathematical with the books by Courant and Hilbert and Sobolev.
In his view, the beauty of mathematics, being accessible only to a few, is not enough, and so most mathematicians 'should turn to the original sources in their work, that is, to the applications of mathematics.'

Basing his own study and research on that of Faraday, he developed the theory of the electromagnetic field on a mathematical basis and made possible a much greater understanding of the phenomena in this field.
He was led to the conclusion that electric and magnetic energy travel in transverse waves that propagate at a speed equal to that of light; light is thus only one type of

 James Clerk Maxwell (1831-1879)
James Clerk Maxwell (1831-1879), Scottish physicist, widely considered by twentieth and twenty-first century physicists to have been one of the most significant figures of the nineteenth century.
Thus encouraged by his father and the natural philosopher James Forbes (1809-1868), the fourteen year old Maxwell produced his first publication: a paper describing a simple mechanical means of drawing mathematical curves with a piece of string.(2) This combination of algebraic mathematics with elements of geometry would remain a distinctive feature of Maxwell's work.
These were not of a particularly mathematical nature - Faraday having had little formal training and having approached the subject from a strongly experimental, rather than theoretical point of view.
