Max Tegmark leads us on an astonishing journey through past, present and future, and through the physics, astronomy and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate multiverse. In a dazzling combination of both popular and groundbreaking science, he not only helps us grasp his often mind-boggling theories, but he also shares with us some of the often surprising triumphs and disappointments that have shaped his life as a scientist. Fascinating from first to last—this is a book that has already prompted the attention and admiration of some of the most prominent scientists and mathematicians.

Mi ayer, al que me referiré en este libro, es 1947, año en el que me gradué. En ese entonces, ser médico significaba haber adquirido los conocimientos teóricos en la facultad y los prácticos en los hospitales. El conocimiento médico avanzaba de a pie y con paso de paseo. Los médicos podían ser clínicos y cirujanos, y abarcar varias especialidades. Ser médico hoy es muy diferente. A la responsabilidad ética de antaño hacia la propia conciencia, se ha sumado la responsabilidad legal respecto de pacientes muchas veces hostiles y estimulados por abogados poco escrupulosos. Mañana (un mañana que ya es hoy) se le añadirá todavía la responsabilidad económica, exigida por quienes gerencian los sistemas de salud. Así, cualquier clínico, además de enfrentar problemas activos de un paciente concreto, deberá enfrentar –ya lo hace hoy–problemas probabilísticos. Ayer, hoy y mañana no son sólo cambios cronológicos, sino también variaciones de pautas culturales. Sabemos que no podemos detener el tiempo; aun así, podemos defender de la erosión las pautas culturales que creemos dignas. Hasta hace algunas décadas, el médico vivía la pauta cultural de la entrega generosa y la sabiduría, que hoy debe cambiar por la de la efectividad y la eficiencia. El esfuerzo debe apuntar, entonces, a conciliar ambas culturas; el desafío es cómo hacerlo. Alberto Agrest Sus escritos, que deberían ser de lectura obligada para quienes se dedican a la medicina y más aún para las nuevas generaciones que planean hacerlo, lo han convertido ya en un clásico de la reflexión sobre el destino de la medicina contemporánea.

In 2975, the orphan Yatima is grown from a randomly mutated digital mind seed in the conceptory of Konishi polis. Yatima explores the Coalition of Polises, the network of computers where most life in the solar system now resides, and joins a friend, Inoshiro, to borrow an abandoned robot body and meet a thriving community of “fleshers” in the enclave of Atlanta. Twenty-one years later, news arrives from a lunar observatory: gravitational waves from Lac G-1, a nearby pair of neutron stars, show that the Earth is about to be bathed in a gamma-ray flash created by the stars’ collision — an event that was not expected to take place for seven million years. Yatima and Inoshiro return to Atlanta to try to warn the fleshers, but meet suspicion and disbelief. Some lives are saved, but the Earth is ravaged. In the aftermath of the disaster, the survivors resolve to discover the cause of the neutron stars’ premature collision, and they launch a thousand polises into interstellar space in search of answers. This diaspora eventually reaches a planet subtly transformed to encode a message from an older group of travellers: a greater danger than Lac G-1 is imminent, and the only escape route leads beyond the visible universe.

From the bestselling author of the acclaimed Chaos and Genius comes a thoughtful and provocative exploration of the big ideas of the modern era: Information, communication, and information theory. Acclaimed science writer James Gleick presents an eye-opening vision of how our relationship to information has transformed the very nature of human consciousness. A fascinating intellectual journey through the history of communication and information, from the language of Africa’s talking drums to the invention of written alphabets; from the electronic transmission of code to the origins of information theory, into the new information age and the current deluge of news, tweets, images, and blogs. Along the way, Gleick profiles key innovators, including Charles Babbage, Ada Lovelace, Samuel Morse, and Claude Shannon, and reveals how our understanding of information is transforming not only how we look at the world, but how we live.

'Implicit cognition', describes the fascinating learning, memory, and performance processes which take place without the subject's 'explicit' awareness. A well known example is patients under anaesthetic who, without being able to verbally recall the surgeons' conversation, do show someretention of the conversation. Researchers disagree widely over the importance, and even the existence, of implicit cognition as an issue in human psychology. This book brings together several internationally known authors with conflicting views on the subject, providing a lively and informativeoverview of this controversial area.

The world has changed radically since 1989, when the General Assembly declared the period from 1990 to 1999 as the United Nations Decade of International Law. During that time, the international community claimed some major achievements as reflected by the adoption of conventions and treaties. This publication presents a collection of essays from legal advisers of States and international organizations, all of whom are among those committed to promoting respect for international law. Their contribution provides a practical perspective on international law, viewed from the standpoint of those involved in its formation, application and administration.
