Paul Halpern

A rich and rewarding history of one of the most astounding ideas in physics and astronomy (Marcia Bartusiak) that the universe we know isnt the only one Our books, our moviesour imaginationsare obsessed with extra dimensions, alternate timelines, and the sense that all we see might not be all there is. In short, we cant stop thinking about the multiverse. As it turns out, physicists are similarly captivated. In The Allure of the Multiverse, physicist Paul Halpern tells the epic story of how science became besotted with the multiverse, and the controversies that ensued. The questions that brought scientists to this point are big and deep: Is reality such that anything can happen, must happen? How does quantum mechanics choose the outcomes of its apparently random processes? And why is the universe habitable? Each question quickly leads to the multiverse. Drawing on centuries of disputation and deep vision, from luminaries like Nietzsche, Einstein, and the creators of the Marvel Cinematic Universe, Halpern reveals the multiplicity of multiverses that scientists have imagined to make sense of our reality. Whether we live in one of many different possible universes, or simply the only one there is, might never be certain. But Halpern shows one thing for sure: how stimulating it can be to try to find out.

The story of the unlikely friendship between the two physicists who fundamentally recast the notion of time and history In 1939, Richard Feynman, a brilliant graduate of MIT, arrived in John Wheelers Princeton office to report for duty as his teaching assistant. A lifelong friendship and enormously productive collaboration was born, despite sharp differences in personality. The soft-spoken Wheeler, though conservative in appearance, was a raging nonconformist full of wild ideas about the universe. The boisterous Feynman was a cautious physicist who believed only what could be tested. Yet they were complementary spirits. Their collaboration led to a complete rethinking of the nature of time and reality. It enabled Feynman to show how quantum reality is a combination of alternative, contradictory possibilities, and inspired Wheeler to develop his landmark concept of wormholes, portals to the future and past. Together, Feynman and Wheeler made sure that quantum physics would never be the same again.

A respected physics professor and author breaks down the great debate over the Big Bang and the continuing quest to understand the fate of the universe. Today, the Big Bang is so entrenched in our understanding of the cosmos that to doubt it would seem crazy. But as Paul Halpern shows in Flashes of Creation, just decades ago its mere mention caused sparks to fly. At the center of the debate were Russian American physicist George Gamow and British astrophysicist Fred Hoyle. Gamow insisted that a fiery explosion explained how the elements of the universe were created. Attacking the idea as half-baked, Hoyle countered that the universe was engaged in a never-ending process of creation. The battle was fierce. In the end, Gamow turned out to be right -- mostly -- and Hoyle, along with his many achievements, is remembered for giving the theory the silliest possible name: "The Big Bang." Halpern captures the brilliance of both thinkers and reminds us that even those proved wrong have much to teach us about boldness, imagination, and the universe itself.

From Aristotles Physics to quantum teleportation, learn about the scientific pursuit of instantaneous connections in this insightful examination of our world. For millennia, scientists have puzzled over a simple question: Does the universe have a speed limit? If not, some effects could happen at the same instant as the actions that caused them -- and some effects, ludicrously, might even happen before their causes. By one hundred years ago, it seemed clear that the speed of light was the fastest possible speed. Causality was safe. And then quantum mechanics happened, introducing spooky connections that seemed to circumvent the law of cause and effect. Inspired by the new physics, psychologist Carl Jung and physicist Wolfgang Pauli explored a concept called synchronicity, a weird phenomenon they thought could link events without causes. Synchronicity tells that sprawling tale of insight and creativity, and asks where these ideas -- some plain crazy, and others crazy powerful -- are taking the human story next.

El tiempo es la única riqueza que no se puede acumular. El libro nos muestra los diferentes caminos para llegar a entender qué es y qué significa el tiempo en nuestra vida. De forma accesible y fácil de comprender por el publico en general se examinan los diferentes puntos de vista de filosofos historiadores teologos literatos o fisicos: desde Aristoteles a Nietzsche de los griegos a Borges o de Einstein al mismisimo Stephen Hawking. Un libro que acerca al gran publico un tema que parecia exclusivo de fisicos y hombres de ciencia.

Durante las primeras décadas del siglo xx, la física vivió una de sus transformaciones más profundas. La mecánica cuántica desbarató el modelo clásico del universo y colocó la incertidumbre en el centro mismo de la realidad. Paradojicamente, algunos de sus arquitectos mas destacados Albert Einstein y Erwin Schrodinger no aceptaron del todo las consecuencias de la teoria que ayudaron a fundar.Einstein nunca se resigno a que el azar gobernara el comportamiento de la naturaleza. Su celebre declaracion Dios no juega a los dados con el universo condensa su rechazo al caracter probabilistico de la nueva fisica. Schrodinger, por su parte, concibio su famoso experimento mental del gato no como una defensa, sino como una denuncia del sinsentido que veia en la interpretacion dominante.Este libro reconstruye el largo y complejo trayecto de ambos cientificos en su intento por reformular la teoria cuantica. Paul Halpern, fisico teorico y reconocido divulgador, rastrea su evolucion intelectual, desde la busqueda compartida de una explicacion mas profunda hasta la divergencia de caminos y enfoques. No se trata solo de una disputa cientifica: es tambien una historia de ideales enfrentados, de resistencia ante lo incomprensible y de una voluntad tenaz por encontrar orden en el caos.Un retrato minucioso y absorbente de dos mentes brillantes que desafiaron las reglas de su tiempo en nombre de una verdad mas coherente.

"A fascinating and thought-provoking story, one that sheds light on the origins of . . . the current challenging situation in physics." -- Wall Street Journal When the fuzzy indeterminacy of quantum mechanics overthrew the orderly world of Isaac Newton, Albert Einstein and Erwin Schrger were at the forefront of the revolution. Neither man was ever satisfied with the standard interpretation of quantum mechanics, however, and both rebelled against what they considered the most preposterous aspect of quantum mechanics: its randomness. Einstein famously quipped that God does not play dice with the universe, and Schrger constructed his famous fable of a cat that was neither alive nor dead not to explain quantum mechanics but to highlight the apparent absurdity of a theory gone wrong. But these two giants did more than just criticize: they fought back, seeking a Theory of Everything that would make the universe seem sensible again. In Einsteins Dice and Schrgers Cat, physicist Paul Halpern tells the little-known story of how Einstein and Schrger searched, first as collaborators and then as competitors, for a theory that transcended quantum weirdness. This story of their quest-which ultimately failed-provides readers with new insights into the history of physics and the lives and work of two scientists whose obsessions drove its progress. Today, much of modern physics remains focused on the search for a Theory of Everything. As Halpern explains, the recent discovery of the Higgs Boson makes the Standard Model-the closest thing we have to a unified theory- nearly complete. And while Einstein and Schrger failed in their attempt to explain everything in the cosmos through pure geometry, the development of string theory has, in its own quantum way, brought this idea back into vogue. As in so many things, even when they were wrong, Einstein and Schrger couldnt help but get a great deal right.
