The First Galaxies in the Universe

This book is about plants, but it is not a treatise on botany. Through its pages, you will learn how plants have influenced our culture, how they feed, how they live, how they relate, how they reproduce and what mechanisms they have to defend themselves or adapt to the environment.

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...

Humanity's understanding of the physical world is full of gaps. Not tiny little gaps you can safely ignore -- there are huge yawning voids in our basic notions of how the world works. Jorge Cham and Daniel Whiteson team up to explore everything we don't know about the universe, and while introducing the biggest mysteries in physics, they also helpfully demystify many complicated things we do know. And although the universe is full of weird things that don't make any sense, Cham and Whiteson make a case that the questions we can't answer are as interesting as the ones we can, and they invite...

No es cierto que usamos únicamente el 10% del cerebro, que en luna llena nazcan más criaturas, que las avestruces escondan la cabeza bajo tierra o que el agua de la pila gire al revés en el hemisferio sur. Todas estas afirmaciones son mitos decorados con apariencia de verdades científicas. Como todos los mitos, pueden tener gracia y resultar estimulantes para la imaginación, pero siempre es importante saber distinguir entre mito y realidad. En este libro podemos descubrir lo que hay detrás de cien de estos mitos.
