Carl Sagan Libros

¿Estamos al borde de una nueva edad oscura de irracionalismo y superstición? En este libro conmovedor el incomparable Carl Sagan demuestra con brillantez que el pensamiento científico es necesario para salvaguardar nuestras instituciones democráticas y nuestra civilización técnica. El mundo y sus demonios es el libro más personal de Sagan, y está lleno de historias humanas entrañables y reveladoras. El autor, con las experiencias de su propia infancia y la apsionante historia de los descubrimientos de la ciencia, muestra cómo el método del pensamiento racional puede superar prejucios y supersticiones para dejar al descubierto la verdad, con frecuencia, resulta sorprendente.

Un magnífico repaso del pasado, presente y futuro del conocimiento científico. El autor, planteando preguntas provocativas, une la ciencia y la filosofía en un modelo coherente y convincente de comprensión del mundo. El cosmos es una historia sobre el largo viaje de descubrimiento de la humanidad y sobre aquellos que han tenido un impacto significativo en la ciencia contemporánea. Carl Sagan, desde una perspectiva cósmica, observa nuestro planeta, un brillante joya azul, habitado por seres que apenas comienzan a comprender el sentido de la unidad con el mundo que les rodea y se embarcan en el vasto océano del cosmos. Gracias a su asombrosa habilidad para presentar temas científicos de manera comprensible y emocionante, se crea una narrativa clara sobre la ciencia y cómo han evolucionado simultáneamente la ciencia y la civilización. El autor discute, entre otros temas, la antigua Biblioteca de Alejandría, el origen de la vida y la materia, las estrellas y los planetas, los fundamentos de la teoría de la evolución y las misiones de sondas espaciales. También reflexiona sobre los últimos descubrimientos relacionados con la vida más allá de la Tierra y las posibles formas de comunicarse con seres de otros planetas.

Carl Sagan's prophetic vision of the tragic resurgence of fundamentalism and the hope-filled potential of the next great development in human spirituality. The late great astronomer and astrophysicist describes his personal search to understand the nature of the sacred in the vastness of the cosmos. Exhibiting a breadth of intellect nothing short of astounding, Sagan presents his views on a wide range of topics, including the likelihood of intelligent life on other planets, creationism and so-called intelligent design, and a new concept of science as informed worship. Originally presented at the centennial celebration of the famous Gifford Lectures in Scotland in 1985 but never published, this book offers a unique encounter with one of the most remarkable minds of the twentieth century.

A visit to a pancake shop leads to an unexpected May-December romance that breathes life into the monotonous routine of an older salaryman.

'Careful scientific argument laced with a dash of speculation. It is a heady mixture . . . Sagan and Shklovskii have explored, with great verve and absorbing detail, what could lie outside us'. JOHN DAVY/THE OBSERVER This book, the product of a unique collaboration between a world-famous Russian astronomer and a leading American space scientist, is the first popular and modern discussion of the entire panorama of natural evolution. It covers the origins of the universe, the evolution of stars and planets, the beginnings of life on earth, and the development of intelligence and technical civilisations among galactic communities. While acknowledgedly speculative in many place — in, for example, the detailed discussions of interstellar contact — it is an outstanding summary of the present state of scientific knowledge and philosophical interest in these arresting areas of contemporary research. 'I am overjoyed . . . The brotherhood of science is a vital aspect of contemporary life and may offer one road to safety amid the dangers that press upon us. There mere existence of this book by two such authors under today's conditions is a triumph for those of us who cling to this hope'. ISAAC ASIMOV 'A unique collaboration' NEWSWEEK

Además de proporcionarnos un ameno y, en ocasiones, divertido repaso de la historia de las Ciencias Físicas, Stephen Hawking formula en este libro una de las más atrevidas y brillantes propuestas científicas de las últimas décadas: unificar la teoría de la relatividad y la mecánica cuántica para crear una teoría cuántica de la gravedad que puede resumirse en que el Universo no necesita tener un principio ni un final, sería un universo eterno, finito pero sin fronteras y totalmente independiente.

“The scientific discoveries described in this book may turn out . . . to have been the most important research findings in the long history of science.” ―Lewis Thomas, from the Foreward The Cold and the Dark is the record of the Conference on the Long-Term Worldwide Biological Consequences of Nuclear War, held in Washington, D.C., on October 31 to November 1, 1983. The conference involved over 200 scientists from many nations and drew together the best available scientific information. Its central finding was the phenomenon of nuclear winter: a much more profound and long-lasting devastation of the earth and atmosphere than had been believed possible before. In the two principal papers, Carl Sagan presents the atmospheric and climatic consequences of nuclear war and Paul Ehrlich summarizes its biological implications. Also included is the text of the “Moscow Link” ―a dialogue between Soviet and American scientists on nuclear winter―and the technical papers providing the scientific evidence for the book’s conclusions.

Carl Sagan sinnt über die gegenwärtige Lage des wissenschaftlichen Denkens nach, was ihm wunderbar Gelegenheit bietet, uns mit seinen eigenen Kindheitserfahrungen, Pressearchiven, UFO-Geschichten und dem vielfältigen Strandgut der Pseudowissenschaft zu unterhalten. Zwischendurch entlarvt er Entführungen durch Außerirdische, Gesundbeterei und Channeling als Nonsens; er widerlegt die Behauptung, daß die Wissenschaft die Spiritualität zerstört, und bietet ein "Quatsch-Erkennungs-Kit" für das gründliche Durchdenken von politischen, gesellschaftlichen, religiösen und anderen Fragen.

Slavný americký astrofyzik – profesor astronomie a vesmírných věd Carl Sagan (1934–1996), hrál zásadní roli v americkém vesmírném programu. V této sérii přednášek, zaznamenaných z pozůstalosti, se zamýšlí nad existencí mimozemského inteligentního života i nad původem vzniku života obecně. Kniha je doprovázena unikátními fotografiemi vesmíru mimo jiné ze zdrojů NASA.

Jak se máme inteligentně rozhodovat ve světě stále více ovládaném technologiemi, když nechápeme rozdíl mezi pseudovědeckými mýty a ověřitelnými vědeckými hypotézami? Carl Sagan, laureát Pulitzerovy ceny a významný astronom, zastává názor, že vědecké myšlení je kritické nejen pro hledání pravdy, ale i pro dobro našich demokratických institucí.Sagan komentuje naši historii a kulturu, zkoumá a s podloženými fakty vyvrací klamy z dob minulých jako je čarodějnictví, léčení vírou, démoni i UFO. Přes to všechno se v dnešním takzvaném věku informací až znepokojivě daří pseudovědám s příběhy o mimozemských únosech, vyvolávání zemřelých a společných halucinacích, které si vyžadují pozornost a respekt. Jak Sagan jasně a výmluvně dokazuje, zpěv Sirén nerozumu není jen nesprávnou odbočkou naší společnosti, ale nebezpečný pád do temnoty, která může ohrozit naše základní svobody.

Vo svojej vizionárskej knihe Draci z raja jedinečným spôsobom prepája antropológiu, evolučnú biológiu a psychológiu. V roku 1978 za ňu získal Pulitzerovu cenu. Legendárny astronóm a polyhistor v knihe kombinuje poznatky o tom, ako sa vyvíjali ľudské gény a mozog od praveku až po súčasnosť a ako funguje naše myslenie a vnímanie v porovnaní so zvieratami. Text, ktorý od svojho vzniku nestratil nič na aktuálnosti, odhaľuje, ako náš mozog funguje v porovnaní s počítačmi, prečo spíme a snívame alebo ako sa nám ukladajú spomienky. Venuje sa nadčasovým témam ako AI, definícii života a smrti, nášmu vzťahu k prírode, civilizáciám na iných planétach, a vedecké zistenia z rôznych disciplín prepája s mýtmi a legendami, ktoré tvoria súčasť našich dejín a kultúry.
