Mathematica in Theoretical Physics illustrates how Mathematica can be utilized to solve physical problems and deal with theoretical concepts. A translation of the highly successful German language book published by Springer-Verlag in 1993, this title includes over one hundred new pages containing more examples in classical mechanics. Non-trivial examples in electrodynamics, quantum mechanics, and general relativity are also provided. The author also includes the derivation of scaling solutions in non-linear physics and has added an introduction to Mathematica specifically designed for physicists and engineers - expanding and strengthening the original work. The diskette contains program code in Mathematica Notebook format.
