Download or read book Light in the Darkness written by Heino Falcke and published by HarperCollins. This book was released on 2021-05-04 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Bestseller On April 10, 2019, award-winning astrophysicist Heino Falcke presented the first image ever captured of a black hole at an international press conference—a turning point in astronomy that Science magazine called the scientific breakthrough of the year. That photo was captured with the unthinkable commitment of an intercontinental team of astronomers who transformed the world into a global telescope. While this image achieved Falcke’s goal in making a black hole “visible” for the first time, he recognizes that the photo itself asks more questions for humanity than it answers. Light in the Darkness takes us on Falcke’s extraordinary journey to the darkest corners of the universe. From the first humans looking up at the night sky to modern astrophysics, from the study of black holes to the still-unsolved mysteries of the universe, Falcke asks, in even the greatest triumphs of science, is there room for doubts, faith, and a God? A plea for curiosity and humility, Light in the Darkness sees one of the great minds shaping the world today as he ponders the big, pressing questions that present themselves when we look up at the stars.

Download or read book La luz en la oscuridad written by Heino Falcke and published by DEBATE. This book was released on 2021-02-18 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Un viaje extraordinario a los límites del tiempo, el espacio y la mente humana, de la mano de Heino Falcke, galardonado con la Medalla Henry Draper 2021. El 10 de abril de 2019 un equipo internacional de astrónomos liderados por el profesor Heino Falcke maravilló al mundo publicando la primera imagen de un agujero negro. Por fin la comunidad científica conseguía la prueba irrefutable de lo que Einstein había predicho en su teoría de la relatividad acerca de estos fenómenos hacía más de cien años. Sin embargo, las implicaciones de este hallazgo van más allá: si bien son objetos relativamente simples de definir, los agujeros negros plantean algunos de los interrogantes más complejos sobre la naturaleza del espacio, del tiempo, y, por último, de nuestra existencia. En este libro, Falcke no solo nos narra la emocionante historia de esta proeza científica, sino que da un paso más intentando responder a las grandes preguntas filosóficas que este hito plantea: ¿existe algo más allá de la nada?,¿puede la ciencia explicar lo inexplicable?, ¿cuál es el origen de nuestra existencia y qué sentido tiene nuestro paso por el mundo? Para Heino Falcke, la astrofísica y la metafísica, la razón y la fe, no tienen por qué excluirse mutuamente. La luz en la oscuridad esun poderoso alegato a favor de la ciencia que nos habla de lo que sabemos pero también de los misterios que quedan por resolver.

Available in PDF, EPUB and Kindle. Book excerpt: ¿En qué se basan los estudiosos del tema del fin del mundo para advertirnos y apurarnos a que tomemos precauciones? Los creyentes reconocemos que es posible el fin del mundo como lo conocemos porque las señales que la Biblia y los Mensajes Marianos dicen que lo anunciarán... ya las estamos viviendo. Otras culturas antiguas y videntes de todas las épocas también predijeron lo mismo y, sorprendentemente, se han venido realizando sus predicciones. Pero si Ud. es de los que no creen en nada de lo anterior, permítame decirle que, en la realidad actual, con estudios científicos y pruebas de ellos, se ha señalado que existen varias amenazas potenciales para la humanidad y que, de concretarse, efectivamente ACABARÍAN CON EL MUNDO COMO LO CONOCEMOS.

Download or read book 2 0 1 2 written by Hugo Enrique Reyes Devesa and published by Palibrio. This book was released on 2012-03 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: En diversos documentales que han circulado por los medios informativos e inclusive en la Internet, el 2012 aparece el año del Juicio Final o el "Hunab-Ku", según las profecías de los mayas, mencionado que la raza humana y nuestro planeta sufrirán una catástrofe de proporciones inimaginables. Estos hechos se ven vinculados a un fenómeno cósmico que ocurre cada 25, 800 años y que tendrá lugar en el solsticio de invierno del 2012, cuando la Tierra se encuentre alineada con el Sol y el centro de nuestra galaxia, la vía Láctea, donde existe un agujero negro ocasionando alteraciones en el manto terrestre y por consiguiente, en la superficie de nuestro planeta. A raíz de estos augurios que vaticinan un peligro inminente a la Tierra y a sus pobladores, los protagonistas de esta increíble aventura, se hacen a la tarea de iniciar una investigación científica que les proporcionara una información más exacta de la realidad, del peligro que estaba a punto de desatarse, y esto era a la vuelta de la esquina ya que, de ocurrir esta catástrofe, ocurriría en tan solo dos años. El resultado de dicha investigación hace que uno de ellos exponga una hipótesis aterradora y descabellada, la "supe-marea del manto terrestre" ejercida por las fuerzas gravitacionales del Sol y el agujero negro. Con la ayuda de dos geofísicos estadounidenses emprenden una odisea que inicia con la búsqueda de un lugar seguro y la creación de un refugio que pueda contener los embates apocalípticos de dicho efecto gravitacional cósmico. Sin embargo, los eventos dan inicio mucho antes de lo esperado por lo que se ven obligados a adelantar sus planes de huída y de sobrevivencia, viéndose envueltos en una serie de controversias ante las decisiones que tienen que tomar con respecto a cuántos y quiénes debían acudir a San Pedro y lo que tenían que llevar consigo. "Todo lo que inicia tiene un fin". Desde que el ser humano existe, y de acuerdo con la historia que nos habla de Oráculos y profetas, siempre ha esperado con temor el día en que llegue éste final. ¿Ficción o una realidad? ¿El año 2012 pondrá fin a la existencia del ser humano sobre la faz de la Tierra? ¿Podrá soportar nuestro planeta, y nosotros mismo, seremos capaces de sobrevivir a esta devastadora ecuación cósmica? Hugo Enrique Reyes Devesa

Download or read book A Madman Dreams of Turing Machines written by Janna Levin and published by Anchor. This book was released on 2009-02-19 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kurt Gödel’s Incompleteness Theorems sent shivers through Vienna’s intellectual circles and directly challenged Ludwig Wittgenstein’s dominant philosophy. Alan Turing’s mathematical genius helped him break the Nazi Enigma Code during WWII. Though they never met, their lives strangely mirrored one another—both were brilliant, and both met with tragic ends. Here, a mysterious narrator intertwines these parallel lives into a double helix of genius and anguish, wonderfully capturing not only two radiant, fragile minds but also the zeitgeist of the era.

Download or read book Black Hole Blues and Other Songs from Outer Space written by Janna Levin and published by Anchor. This book was released on 2016-03-29 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authoritative story of the headline-making discovery of gravitational waves—by an eminent theoretical astrophysicist and award-winning writer. From the author of How the Universe Got Its Spots and A Madman Dreams of Turing Machines, the epic story of the scientific campaign to record the soundtrack of our universe. Black holes are dark. That is their essence. When black holes collide, they will do so unilluminated. Yet the black hole collision is an event more powerful than any since the origin of the universe. The profusion of energy will emanate as waves in the shape of spacetime: gravitational waves. No telescope will ever record the event; instead, the only evidence would be the sound of spacetime ringing. In 1916, Einstein predicted the existence of gravitational waves, his top priority after he proposed his theory of curved spacetime. One century later, we are recording the first sounds from space, the soundtrack to accompany astronomy’s silent movie. In Black Hole Blues and Other Songs from Outer Space, Janna Levin recounts the fascinating story of the obsessions, the aspirations, and the trials of the scientists who embarked on an arduous, fifty-year endeavor to capture these elusive waves. An experimental ambition that began as an amusing thought experiment, a mad idea, became the object of fixation for the original architects—Rai Weiss, Kip Thorne, and Ron Drever. Striving to make the ambition a reality, the original three gradually accumulated an international team of hundreds. As this book was written, two massive instruments of remarkably delicate sensitivity were brought to advanced capability. As the book draws to a close, five decades after the experimental ambition began, the team races to intercept a wisp of a sound with two colossal machines, hoping to succeed in time for the centenary of Einstein’s most radical idea. Janna Levin’s absorbing account of the surprises, disappointments, achievements, and risks in this unfolding story offers a portrait of modern science that is unlike anything we’ve seen before.

Download or read book 100 Facts About General Relativity and Its Applications written by Science-Based Language Learning Lab and published by eBookIt.com. This book was released on 2024-07-16 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to the 100 Somethings Language Learning Series Welcome to an innovative approach to language learning! This series of books is crafted to help you master a new language (Spanish) through engaging with topics that captivate your interest (General Relativity and Its Applications). Each book is centered around a theme–whether it's art, science, history, or another subject–and presents 100 carefully selected facts, each a gem of knowledge in both English and the target language. Here's how our unique format works: each fact is introduced in the target language where you do your best to interpret the fact. On the next page, the fact is shown in English, and then repeated in the target language where you can start making sense of any unfamiliar terms. This method is not only repetitive to aid memorization but also concise, ensuring that learning is streamlined with no excess verbiage. The second half of the book presents the content in English, then in the target language, and finally in English again, giving you the chance to translate in both directions and demonstrate true mastery of the material. The benefits of this approach are manifold: - Concise Learning: By focusing on simple, one-sentence facts, the learning process is distilled to its essence. This conciseness ensures that every word you learn is impactful and directly related to your interests, making the information easier to remember. - Reinforcement of Learning: Alternating between English and the target language with each fact helps reinforce your new vocabulary and grammatical structures naturally. It bridges the gap between the two languages, solidifying your learning through constant, practical application. - Contextual and Engaged Learning: Associating each new word with a fact about a topic you are passionate about not only makes the vocabulary stickier but also keeps your learning process dynamic and engaging. This method not only teaches you a new language but does so through the lens of your personal passions. - Dual Knowledge Acquisition: As you navigate through these 100 facts, you're not just learning a new language; you're also deepening your knowledge about a specific subject. This dual focus not only enhances the language learning experience but also enriches your understanding of your chosen topic. Designed for learners who thrive on clear, targeted information, this series promises a learning experience that is both educational and enjoyable. Whether you're a curious beginner or looking to broaden your linguistic skills, these books are tailored to make your educational journey as effective and engaging as possible. Embrace this journey of 100 facts, and let your passions fuel your progress in mastering a new language!
