John Gribbin

Este libro nos plantea las bases de lo que será la fascinante ciencia de la Física en el próximo siglo XXI. Se describen los últimos desarrollos que han revolucionado la ciencia moderna. Desde el asombroso mundo de los Quarks la teoria de la relatividad hasta los primeros descubrimientos cientificos sobre el nacimiento del cosmos. Los autores se plantean la necesidad de un cambio de paradigma para entender los nuevos descubrimientos sobre agujeros negros cuerdas cosmicas y la teoria del caos...y como los conceptos sobre el tiempo el espacio y la materia muestran una vision basada en un Universo interconectado.

Time travel is a familiar theme of science fiction but is it really possible Surprisingly time travel is not forbidden by the laws of physics and John Gribbin argues that if it is not impossible then it must be possible Gribbin brilliantly illustrates the possibilities of time travel by comparing familiar themes from science fiction with their real world scientific counterparts including Einstein s theories of relativity black holes quantum physics and the multiverse illuminated by examples from the fictional tales of Robert Heinlein Larry Niven Carl Sagan and others The result is an entertaining guide to some deep mysteries of the Universe which may leave you wondering whether time actually passes at all and if it does whether we are moving forwards or backwards A must read for science fiction fans and anyone intrigued by deep science

The revolution is here In breakthrough after breakthrough pioneering physicists are unlocking a new quantum universe which provides a better representation of reality than our everyday experiences and common sense ever could The birth of quantum computers which like Schrodinger s famous dead and alive cat rely on entities like electrons existing in a mixture of states is starting to turn the computing world on its head In his fascinating study of this cutting edge technology first published as Computing with Quantum Cats and now featuring a new foreword John Gribbin updates his previous views on the nature of quantum reality arguing for a universe of many parallel worlds where everything is real Looking back to Alan Turing s work on the Enigma machine and the first electronic computer Gribbin explains how quantum theory developed to make quantum computers work in practice as well as in principle He takes us beyond the arena of theoretical physics to explore their practical applications from machines which learn through intuition and trial and error to unhackable laptops and smartphones And he investigates the potential for this extraordinary science to allow communication faster than light and even teleportation as we step into a world of

Galaxies are the building blocks of the Universe standing like islands in space each is made up of many hundreds of millions of stars in which the chemical elements are made around which planets form and where on at least one of those planets intelligent life has emerged Our own galaxy the Milky Way is just one of several hundred million other galaxies that we can now observe through our telescopes Yet it was only in the 1920s that we realised that there is more to the Universe than the Milky Way and that there were in fact other islands out there In many ways modern astronomy began with this discovery and the story of galaxies is therefore the story of modern astronomy Since then many exciting discoveries have been made about our own galaxy and about those beyond how a supermassive black hole lurks at the centre of every galaxy for example how enormous forces are released when galaxies collide how distant galaxies provide a window on the early Universe and what the formation of young galaxies can tell us about the mysteries of Cold Dark Matter In this Very Short Introduction renowned science writer John Gribbin describes the extraordinary things that astronomers are learning about galaxies and explains how this can shed light on the origins a

Time travel is a familiar theme of science fiction, but is it really possible?Surprisingly, time travel is not forbidden by the laws of physics - and John Gribbin argues that if it is not impossible then it must be possible.Gribbin brilliantly illustrates the possibilities of time travel by comparing familiar themes from science fiction with their real-world scientific counterparts, including Einstein's theories of relativity, black holes, quantum physics, and the multiverse, illuminated by examples from the fictional tales of Robert Heinlein, Larry Niven, Carl Sagan and others.The result is an entertaining guide to some deep mysteries of the Universe which may leave you wondering whether time actually passes at all, and if it does, whether we are moving forwards or backwards. A must-read for science fiction fans and anyone intrigued by deep science.

En esta obra se analiza detalladamente y con un lenguaje libre de tecnicismos innecesarios, las razones físicas para que tenga lugar el «big crunch» y el universo acabe de un modo análogo a como empe

Excelente y asequible historia de la creación de nuestro universo en la que Gribbin, a través de la narración apasionada de todos los acontecimientos astrofísicos que han originado la aparición de vida en la Tierra, refuta cualquier posibilidad de existencia de civilización inteligente en otros planetas. Una reivindicación científica del valor extraordinario que tiene la vida en nuestro planeta.
