Paul Halpern Livres

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 Wheeler's 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.

Physicist Paul Halpern tells the little-known story of how Einstein and Schrödinger 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. --Publisher's description

The great debate over the Big Bang and the 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.

The concept of multiple unperceived dimensions in the universe is one of the hottest topics in contemporary physics. It is essential to current attempts to explain gravity and the underlying structure of the universe. The Great Beyond begins with Einstein’s famous quarrel with Heisenberg and Bohr, whose theories of uncertainty threatened the order Einstein believed was essential to the universe, and it was his rejection of uncertainty that drove him to ponder the existence of a fifth dimension. Beginning with this famous disagreement and culminating with an explanation of the newest ""brane"" approach, author Paul Halpern shows how current debates about the nature of reality began as age-old controversies, and addresses how the possibility of higher dimensions has influenced culture over the past one hundred years.

From Aristotle's Physics to quantum teleportation, the story of the pursuit of causes that happen faster than the speed of light

The long history of one of physics' most enticing ideas: that the universe we know isn't the only one Our books, our movies--our imaginations--are obsessed with extra dimensions, alternate timelines, and the sense that all we see might not be all there is. In short, we can't 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.

George Gamow żył tak, jak uprawiał fizykę. „Zdejmijcie go z motocykla”, mówiono. „Jeśli się zabije, cofnie fizykę o dwadzieścia lat”. Fredowi Hoyle’owi również nie brakowało fantazji, a jego nagłe zniknięcie z pewnością spowolniłoby rozwój nauki o dekadę lub dwie. Obaj byli żądnymi przygód, ekscentrycznymi samotnikami. Obaj chadzali własnymi ścieżkami. Obaj konwenansów nienawidzili równie mocno, jak mocno kochali proces odkrywania. Obaj też uwielbiali snuć fantastyczne opowieści naukowe, promieniujące daleko poza świat akademicki. W czasach, gdy Wielki Wybuch był zaledwie mglistą teorią, a astrofizyka znajdowała się w impasie, działali niczym dwa odpychające się magnesy. Reprezentując skrajnie różne poglądy – prowokowali do dyskusji. Przeplatająca wątki obu wybitnych kosmologów podwójna biografia autorstwa Paula Halperna jest czymś więcej niż sumą prostą składników. Jest kroniką intelektualnego pojedynku, w którym rodził się nowy, współczesny obraz genezy i losów Wszechświata.

Žijeme v období, ktoré je z hľadiska výskumu stavby vesmíru naozaj vzrušujúce. Na jednej strane sme sa v posledných rokoch všeličo dozvedeli o hviezdach, galaxiách a iných astronomických objektoch, ale zdá sa, že Hubblov vesmírny teleskop takmer každých niekoľko týždňov prináša nové objavy. Na druhej strane aj sebaistí vedci sa bezradne škrabú po hlave nad takými problémami, ako je otázka veku kozmu, dilema tmavej hmoty, záhada veľkého atraktora či osud vesmíru...
