The target of this booklet is to show the reader to the vital function that mathematics---often very abstract---plays in glossy physics. beginning with the inspiration of vector areas, the 1st 1/2 the publication develops subject matters as assorted as algebras, classical orthogonal polynomials, Fourier research, complicated research, differential and necessary equations, operator idea, and multi-dimensional Green's features. the second one half the ebook introduces teams, manifolds, Lie teams and their representations, Clifford algebras and their representations, and fiber bundles and their functions to differential geometry and gauge theories.

 This moment variation is a considerable revision of the 1st one with a whole rewriting of many chapters and the addition of latest ones, together with chapters on algebras, illustration of Clifford algebras and spinors, fiber bundles, and gauge theories. The spirit of the 1st version, specifically the stability among rigor and actual program, has been maintained, as is the abundance of ancient notes and labored out examples that show the "unreasonable effectiveness of arithmetic" in smooth physics.

Einstein has famously acknowledged, "The so much incomprehensible factor approximately nature is that it truly is comprehensible." What he had in brain used to be reiterated in one other one among his well-known fees about the query of the way " ... arithmetic, being finally a manufactured from human notion, is so admirably acceptable to the items of reality." it's a query that involves everyone's brain while encountering the hugely summary arithmetic required for a deep realizing of recent physics. it's the adventure that Eugene Wigner so profoundly defined as "the unreasonable effectiveness of arithmetic within the normal sciences."

Some compliment for the former edition:

PAGEOPH [Pure and utilized Geophysics]

 Review by way of Daniel Wojcik, college of Maryland

 "This quantity might be a great addition to any assortment. The ebook is definitely written and factors are typically transparent. Lives of well-known mathematicians and physicists are scattered in the e-book. they're relatively prolonged, frequently fun, making great interludes. a number of workouts support the coed perform the tools brought. … i've got lately been utilizing this publication for a longer time and purchased a liking for it. between the entire to be had books treating mathematical tools of physics this one definitely stands proud and elegantly it'll go well with the desires of many physics readers."

 

ZENTRALBLATT MATH

 Review by way of G.Roepstorff, collage of Aachen, Germany

 "… in contrast to such a lot latest texts with an identical emphasis and viewers, that are simply collections of evidence and formulation, the current booklet is extra systematic, self-contained, with a degree of presentation that has a tendency to be extra formal and summary. This involves proving numerous theorems, lemmas, and corollaries, deferring lots of the functions that physics scholars could be drawn to to the instance sections in details. certainly, there are 350 worked-out examples and approximately 850 difficulties. … a really great function is the way in which the writer intertwines the formalism with the existence tales and anecdotes of a few mathematicians and physicists, top at their occasions. As is usually the case, the historic view element is helping to appreciate and delight in the guidelines awarded within the textual content. … For the physics pupil in the midst of his education, it's going to definitely end up to be super useful." 

THE PHYSICIST 

Review by means of Paul Davies, Orion Productions, Adelaide, Australia

 "I am happy to have such a lot of issues accumulated in one quantity. the entire methods are there after all, yet supported by means of adequate rigour and substantiation to make the committed mathematical physicist sigh with delight."

EMS [EUROPEAN MATHEMATICAL SOCIETY] NEWSLETTER

 "This publication is a condensed exposition of the maths that's met in so much components of physics. The presentation attains an exceptional stability among the formal creation of recommendations, theorems and proofs on one hand, and the utilized technique at the different, with many examples, absolutely or partly solved difficulties, and old feedback. a powerful quantity of arithmetic is roofed. … This booklet will be warmly instructed as a simple resource for the examine of arithmetic for complicated undergraduates or starting graduate scholars in physics and utilized arithmetic, and in addition as a reference ebook for all operating mathematicians and physicists ."
