The middle class is often viewed as the heart of American society, the key to the country's democracy and prosperity. Most Americans believe they belong to this group, and few politicians can hope to be elected without promising to serve the middle class. Yet today the American middle class is increasingly seen as under threat. In The American Middle Class: A Cultural History, Lawrence R. Samuel charts the rise and fall of this most definitive American population, from its triumphant emergence in the post-World War II years to the struggles of the present day.

Each chapter first provides an overview of the basic physical principles which are the basis for the numerical and mathematical modeling on the respective length-scale. The book includes the micro-scale, the meso-scale and the macro-scale, and the chapters follow this classification. The book explains in detail many tricks of the trade of some of the most important methods and techniques that are used to simulate materials on the perspective levels of spatial and temporal resolution. Case studies are included to further illustrate some methods or theoretical considerations. Example applications for all techniques are provided, some of which are from the author?s own contributions to some of the research areas. The second edition has been expanded by new sections in computational models on meso/macroscopic scales for ocean and atmosphere dynamics. Numerous applications in environmental physics and geophysics had been added. 606 $aPhysics 606 $aMaterials science 606 $aComputer science$xMathematics 606 $aApplied mathematics 606 $aEngineering mathematics 606 $aGeophysics 606 $aNumerical and Computational Physics, Simulation$3https://scigraph.springernature.com/ontologies/product-market-codes/P19021 606 $aCharacterization and Evaluation of Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/Z17000 606 $aComputational Mathematics and Numerical Analysis$3https://scigraph.springernature.com/ontologies/product-market-codes/M1400X 606 $aMathematical and Computational Engineering$3https://scigraph.springernature.com/ontologies/product-market-codes/T11006 606 $aGeophysics and Environmental Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P32000 615 0$aPhysics. 615 0$aMaterials science. 615 0$aComputer science$xMathematics. 615 0$aApplied mathematics. 615 0$aEngineering mathematics. 615 0$aGeophysics. 615 14$aNumerical and Computational Physics, Simulation. 615 24$aCharacterization and Evaluation of Materials. 615 24$aComputational Mathematics and Numerical Analysis. 615 24$aMathematical and Computational Engineering. 615 24$aGeophysics and Environmental Physics. 676 $a530.1 700 $aSteinhauser$b Martin Oliver$4aut$4http://id.loc.gov/vocabulary/relators/aut$0916045 906 $aBOOK 912 $a9910155328003321 996 $aComputational Multiscale Modeling of Fluids and Solids$92053553 997 $aUNINA
