Es hora de acostarse (Time for Bed)

Of all the different areas in computational chemistry, density functional theory (DFT) enjoys the most rapid development. Even at the level of the local density approximation (LDA), which is computationally less demanding, DFT can usually provide better answers than Hartree-Fock formalism for large systems such as clusters and solids. For atoms and molecules, the results from DFT often rival those obtained by ab initio quantum chemistry, partly because larger basis sets can be used. Such encouraging results have in turn stimulated workers to further investigate the formal theory as well as...

Obra destinada no sólo a los especialistas sino a todos los interesados por el conocimiento del último período frío, denominado Pequeña Edad del Hielo (s. XIII-XIX), con especial referencia al análisis y reconstrucción del avance glaciar histórico en los Picos de Europa y su posterior proceso de deglaciación, lo que nos conduce hasta la actualidad, permitiéndonos dilucidar la evolución del modelado de las montañas como respuesta a los cambios climáticos

Making knowledge about evolution available to everyone, this simple and entertaining book offers answers to the most frequently asked questions. Throughout the text, the reader is reminded of the importance of understanding evolutionary processes in order to approach present day human behavior, including social conduct, as well as the difficulty of trying to decipher the nature of modern human beings without going back to their zoological origin. Divided into two sections, the first one builds the foundation for the latter, which explains the evolution of life, beginning at the physical...
