PBS · 1980 · Presenter: Carl Sagan
Cosmos: A Personal Voyage is a thirteen-part television series that covers a wide range of scientific subjects, including the origin of life and a perspective of our place in the universe.
I turned 16 while this series aired, and was completely captivated by it. My father had been a fan of Bronowski's Ascent of Man and Burke's Connections. Those were outstanding series in their own rights. But I was all about astronomy, and Sagan's journey resonated with me.
Sagan's Cosmos aged very well and is still regarded as among the best science miniseries ever produced. And as WIRED noted, Sagan's still right all these years later.
The way I used Cosmos was as a "chill day" between units in Physics. For my students, and for me. We all needed it. I kept their question sets after each episode. At the end of the year, I'd give them their sets back and they could use them on a "Cosmos Unit Test". Easy with the completed question sets; challenging without. Definitely among my longest "delayed gratification" activities.
Carl Sagan opens the program with a description of the cosmos and a "Ship of the Imagination" (shaped like a dandelion seed). The ship journeys through the universe's hundred billion galaxies, the Local Group, the Andromeda Galaxy, the Milky Way, the Orion Nebula, our Solar System, and finally the planet Earth. Eratosthenes' successful calculation of the circumference of Earth leads to a description of the ancient Library of Alexandria. Finally, the "Ages of Science" are described, before pulling back to the full span of the Cosmic Calendar. Note: the revised version of the series adds an introduction by Ann Druyan to this episode, recorded after Sagan's death, in which she discusses some of the changes that occurred in the years after its broadcast.This episode emphasizes astronomy: from the universe to the round Earth.
