Nuestra casa está ardiendo: Una familia y de un planeta en crisis
by Varios Autores Greta ThunbergEsta es la historia de una familia que afronta su propia crisis enfrentándose a una crisis aún mayor: la de nuestro planeta #HuelgaPorElClima «Quiero que actúen como si nuestra casa estuviera ardiendo. Porque así es.» Con estas palabras cerraba Greta Thunberg su discurso en el foro de Davos el 25 de enero de 2019, cinco meses después de iniciar su huelga por el clima. Desde entonces, la activista ha sumado a millones de personas a su lucha para salvar el planeta. Pero ¿qué llevó a una adolescente de quince años a tomar la decisión de plantarse en solitario ante el Parlamento de su país y desde allí intentar cambiar el mundo? Esta historia, escrita por la familia Thunberg y narrada por la voz de la madre, la cantante de ópera Malena Ernman, comienza cuando la pequeña Greta cae en una depresión severa y deja de comer por el impacto de un documental sobre el cambio climático. Sus padres emprenden una batalla feroz por su salud hasta que le diagnostican síndrome de Asperger, autismo de alto funcionamiento y TOC. Al poco tiempo, la hija menor, Beata, muestra signos de trastornos similares. Este es el grito de auxilio de una niña para convencer, primero a los suyos y luego al mundo, de que la sociedad está tan enferma como el planeta y de que es urgente que reaccione. Una narración sobrecogedora de una familia moderna que supera su propia crisis desafiando una crisis global. La crítica ha dicho...«Esta época necesita gente como Greta. Las ideas están en el aire y hace falta alguien que las formule.»Svetlana Alexiévich «Escuchemos a Greta. Tal vez todavía estemos a tiempo.»J. M. G. Le Clézio «El relato extraordinario de cómo una familia logra erguirse, con gran lucidez moral, ante la tremenda responsabilidad de estar vivos en el momento en que nuestras decisiones colectivas inmediatas están determinando el futuro de la vida en la Tierra. [...] Greta Thunberg ya ha inspirado un hito global: este libro guarda la esencia de cómo ganaremos.»Naomi Klein «La historia de Greta es sorprendente y emocionante. [...] No creo que exista un precedente similar en toda la historia: que una adolescente [...] lidere un movimiento de millones de personas.»David Wallace-Wells (autor de El planeta inhóspito), El País «Greta arde de autenticidad, es un puro aullido de desesperación y de incredulidad ante nuestra ceguera.»Rosa Montero «La familia Thunberg-Ernman narra de manera amena y con una sinceridad apabullante su paso devastador por los infiernos.»Eva Stegen, The Friday «Una lectura poderosa y convincente, distópica y optimista, personal y objetiva.»Marie Pettersson, Sydsvenskan «Un grito [...], un testimonio escrito ahora que el presagio de un desastre avanza. La propia crisis de una familia es, en realidad, una prueba de su inteligencia.»Sverker Sörlin, Dagens Nyheter «Un libro conmovedor.»Arno Widmann, Berliner Zeitung «Una mirada sorprendente e introspectiva de una familia que vive adaptándose a los reveses del destino.»Steffen Trumpf, dpa «Valiente y tenaz.»Anna Hellgren, Expressen «Una historia extraordinaria y emocionante.»Alexandra von Poschinger, Passauer Neue Presse

Numerical Approximation Methods: π ≈ 355/113
by Harold CohenThis book presents numerical and other approximation techniques for solving various types of mathematical problems that cannot be solved analytically. In addition to well known methods, it contains some non-standard approximation techniques that are now formally collected as well as original methods developed by the author that do not appear in the literature. This book contains an extensive treatment of approximate solutions to various types of integral equations, a topic that is not often discussed in detail. There are detailed analyses of ordinary and partial differential equations and descriptions of methods for estimating the values of integrals that are presented in a level of detail that will suggest techniques that will be useful for developing methods for approximating solutions to problems outside of this text. The book is intended for researchers who must approximate solutions to problems that cannot be solved analytically. It is also appropriate for students taking courses in numerical approximation techniques.
Numerical Approximation of Hyperbolic Systems of Conservation Laws (Applied Mathematical Sciences #118)
by Edwige Godlewski Pierre-Arnaud RaviartThis monograph is devoted to the theory and approximation by finite volume methods of nonlinear hyperbolic systems of conservation laws in one or two space variables. It follows directly a previous publication on hyperbolic systems of conservation laws by the same authors.

This new edition includes more examples such as MHD and shallow water, with an insight on multiphase flows. Additionally, the text includes source terms and well-balanced/asymptotic preserving schemes, introducing relaxation schemes and addressing problems related to resonance and discontinuous fluxes while adding details on the low Mach number situation.

Numerical Exploration of Isolated GaAs-AlGaAs Quantum Well (Synthesis Lectures on Engineering, Science, and Technology)
by Sujaul Chowdhury Urmi TalukderThis book begins with the eigenvalue equation of energy and presents calculation of the energy spectrum of GaAs-AlGaAs Quantum Well using finite difference method and knowledge of potential energy profile, without using expressions for eigenfunctions, continuity of eigenfunctions, or their spatial derivatives at the two abrupt potential steps. The authors find that the results are almost the same as those obtained by solving numerically using regula falsi method, and transcendental equations that are obeyed by the energy levels, where the transcendental equations are obtained by requiring continuity of eigenfunctions and of their spatial derivatives at the two potential steps. Thus, this book confirms that it is possible to numerically calculate the energy spectrum of Quantum Well by the finite difference method when it is not correct or when it is not possible to use continuity of eigenfunctions and their spatial derivatives at the two abrupt potential steps. The authors also showthat it is possible to use the finite difference method in cases where the potential steps are non-abrupt. The book demonstrates this by calculating the energy spectrum of isolated parabolic Quantum Well of finite depth using finite difference method.

Numerical Methods for Metamaterial Design
by Kenneth DiestThis book describes a relatively new approach for the design of electromagnetic metamaterials. Numerical optimization routines are combined with electromagnetic simulations to tailor the broadband optical properties of a metamaterial to have predetermined responses at predetermined wavelengths. After a review of both the major efforts within the field of metamaterials and the field of mathematical optimization, chapters covering both gradient-based and derivative-free design methods are considered. Selected topics including surrogate-base optimization, adaptive mesh search, and genetic algorithms are shown to be effective, gradient-free optimization strategies. Additionally, new techniques for representing dielectric distributions in two dimensions, including level sets, are demonstrated as effective methods for gradient-based optimization. Each chapter begins with a rigorous review of the optimization strategy used, and is followed by numerous examples that combine the strategy with either electromagnetic simulations or analytical solutions of the scattering problem. Throughout the text, we address the strengths and limitations of each method, as well as which numerical methods are best suited for different types of metamaterial designs. This book is intended to provide a detailed enough treatment of the mathematical methods used, along with sufficient examples and additional references, that senior level undergraduates or graduate students who are new to the fields of plasmonics, metamaterials, or optimization methods; have an understanding of which approaches are best-suited for their work and how to implement the methods themselves.
