Carl Sagan’s: Cosmos Part 8 – Travels in space and time

admin — Tue, 08 May 2012 14:47:16 +0000

Ideas about time and space are explored in the changes that constellations undergo over time, the redshift and blue shift measured in interstellar objects, time dilation in Albert Einstein’s theory of relativity, the designs of both Leonardo da Vinci and spacecraft that could travel near light speed, time travel and its hypothetical effects on human history, the origins of the Solar System, the history of life, and the immensity of space. In Cosmos Update, the idea of faster-than-light travel by wormholes (researched by Kip Thorne and shown in Sagan’s novel Contact) is discussed.

Carl Sagan’s: Cosmos Part 3 – Harmony of the Worlds

admin — Tue, 17 Apr 2012 15:02:32 +0000

Beginning with the separation of the fuzzy thinking and pious fraud of astrology from the careful observations of astronomy, Sagan follows the development of astronomical observation. Beginning with constellations and ceremonial calendars (such as those of the Anasazi), the story moves to the debate between Earth and Sun-centered models: Ptolemy and the geocentric worldview, Copernicus’ theory, the data-gathering of Tycho Brahe, and the achievements of Johannes Kepler (Kepler’s laws of planetary motion and the first science-fiction novel).

Carl Sagan’s: Cosmos Part 7 – The Backbone of Night

admin — Tue, 03 Apr 2012 15:04:12 +0000

Carl Sagan teaches students in a classroom in his childhood home in Brooklyn, New York, which leads into a history of the different mythologies about stars and the gradual revelation of their true nature. In ancient Greece, some philosophers (Aristarchus of Samos, Thales of Miletus, Anaximander, Theodorus of Samos, Empedocles, Democritus) freely pursue scientific knowledge, while others (Plato, Aristotle, and the Pythagoreans) advocate slavery and epistemic secrecy.

Carl Sagan’s: Cosmos Part 4 – Heaven and Hell

admin — Tue, 20 Mar 2012 15:14:52 +0000

Sagan discusses comets and asteroids as planetary impactors, giving recent examples of the Tunguska event and a lunar impact described by Canterbury monks in 1178. It moves to a description of the environment of Venus, from the previous fantastic theories of people such as Immanuel Velikovsky to the information gained by the Venera landers and its implications for Earth’s greenhouse effect. The Cosmos Update highlights the connection to global warming.

Sagan reflects on the future of humanity and the question of “who speaks for Earth?” when meeting extraterrestrials. He discusses the very different meetings of the Tlingit people and explorer Jean-François de La Pérouse with the destruction of the Aztecs by Spanish conquistadors, the looming threat of nuclear warfare, and the threats shown by destruction of the Library of Alexandria and the murder of Hypatia. The episode ends with a overview of the beginning of the universe, the evolution of life, and the accomplishments of humanity and makes a plea to for mankind to cherish life and continue its journey in the cosmos. The Cosmos Update notes the preliminary reconnaissance of planets with spacecraft, the fall of the Berlin Wall and the end of apartheid in South Africa, and measures towards the reduction of nuclear weapons.
