Dormir es uno de los aspectos más importantes pero menos comprendidos de nuestra vida. Hasta hace muy poco, la ciencia no tenía respuesta a la pregunta de por qué dormimos, a qué servía o por qué sufrimos consecuencias tan devastadoras para la salud cuando está ausente. En comparación con los otros impulsos básicos de la vida (comer, beber y reproducir), el propósito del sueño sigue siendo más difícil de descifrar. Matthew Walker ofrece una exploración revolucionaria del sueño, examinando cómo afecta cada aspecto de nuestro bienestar físico y mental.
Esta obra está dirigida al primer curso de las carreras pertenecientes al área de Ciencias de la Vida y de la Salud (Biología, Bioquímica, Biotecnología, Ciencia y Tecnología de los Alimentos, Ciencias Ambientales, Ciencias del Mar, Enfermería, Farmacia, Fisioterapia, Ingeniería Agrícola, Óptica y Optometría, Medicina y Veterinaria). Prácticamente todos los programas de Física de estas carreras están recogidos en esta obra, por lo que puede servir de libro de texto en cualquiera de ellas. El énfasis se sitúa en la explicación física de los principales fenómenos y órganos biológicos, así como de las técnicas instrumentales más importantes utilizadas en las ciencias de la salud y en la investigación biológica. El libro tiene en cuenta el nivel con el que acceden a la universidad la mayoría de los estudiantes de estas carreras, que no suelen haber escogido física en segundo de bachillerato. Por este motivo, el manual está pensado para aportar todos los contenidos necesarios de forma clara, didáctica y concisa, por lo que no se necesitan conceptos previos de física para poder seguir el curso con normalidad. La obra está pensada para que, además de como libro de texto, sirva como libro de referencia, ya que aborda temas más avanzados, como la física del impulso nervioso o de la visión o la resonancia magnética nuclear, de enorme interés para las ciencias de la vida.

En el corazón del Universo se encierra un secreto matemático y la clave para desentrañarlo es la Teoría del Todo, una propuesta única y global que explique las leyes de la naturaleza y de la cual pueda derivarse con lógica irrefutable el conocimiento de todas las cosas que nos rodean. En este libro, escrito con un estilo y una claridad inusuales, John D. Barrow, uno de los cosmólogos más reconocidos del mundo, conduce al lector hacia un apasionante viaje desde la creación de los viejos mitos hasta las últimas teorías sobre el big bang, las supercuerdas, los agujeros de gusano, los universos bebé y el misterio cuántico del tiempo.

Este ensayo explica, de manera amena y clara, cuestiones que afectan a nuestras vidas, como la herencia codificada en el ADN, la evolución por medio de la selección natural, la conservación de la energía y el razonamiento matemático. Un libro asequible pensado para ser consultado por un público amplio.

Decía Pitágoras que los números son la esencia de todo lo que es. Y hay motivos de sobra para pensar que no andaba descaminado aquel genial pensador. De hecho, la historia de los números es fascinante, con sus teoremas profundos, sus descubrimientos a veces revolucionarios y sus enigmas lógicos y aritméticos. Este libro, de un excepcional, profundo y creativo matemático español, Antonio Córdoba, presenta la saga de los números, desde los naturales hasta los hipercomplejos, describiendo con especial cuidado algunos parajes de interés, tales como la distribución de los primos, las ecuaciones diofánticas o la no numerabilidad de los reales. Y lo hace poniendo un énfasis especial en cuestiones lindantes con la lógica, como pueden ser el axioma de elección, los ordinales, los cardinales, las paradojas de la teoría ingenua de conjuntos, los sistemas axiomáticos y la imposibilidad ?que se desprende de esa joya del espíritu que es el teorema de Gödel? de una teoría matemática del todo. Lejos de ser un tratado de teoría de números, ni mucho menos de lógica matemática, La saga de los números muestra el arte de las demostraciones rigurosas conduciéndonos a través de algunos de los más bellos y asequibles jardines de la matemática, para así ilustrar los modos de pensar, de demostrar y de escribir esta varias veces milenaria disciplina.
