On a trip to outer space, Ms. Fizzle and the gang learn all about shooting stars, meteorites, and other space rocks. Full color.

The book compiles case studies regarding the biodiversity research and monitoring program of Andean species and habitats carefully chosen as indicators to assess the short- and long-term effects of a linear disturbance: the PERU LNG pipeline. Set in a scientifically unexplored region of the Andes, Monitoring Biodiversity clearly articulates the Smithsonian-led conceptual framework for the implementation in the field by scientists. It addresses scientific and conservation questions addressed by the research protocols, the experimental design, and data gathering. Moreover, the book covers a gap ...

Solo quiero referir a una opinion de Einstein, este magnifico matematico y hombre de bien. Se le pregunto por que la mayoria de los estudiantes se les dificultaba el estudio de las matematicas. Einstein se concreto a decir "La dificultad de las mentes juveniles para entender la matematica estriba en que no han sido suficientemente educadas en el sentimiento del ritmo" Ciertamente, las matematicas, llevan un ritmo interior, el mas profundo que solo la vision del universo puede entregar a la mente y a la contemplacion del intelecto. El arte ornamental siempre se ha proyectado hacia fuera, en...

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...
