While I love this 13-part PBS series that came out in 1980 - the most expensive ever by that network up to that time - which I watched in my 9th grade biology class, could a science teacher still use it today? carlsagan.com (click on "books and dvd") FYI: the dvds also contain updates to the science in the original program - I think the boxset came out in 2001. Youtube has at least one of the 1 hour episodes: #1: "On The Shores Of The Cosmic Ocean".* If you're a science teacher or just a history + science hobbyist, IMO you owe it to youself to watch this awesome series. Sagan is great at taking very ethereal or downright difficult subjects & explaining them in ways us normal people can understand but without talking down to anyone either & fortunately, not in that irritating cutesy or "hip" style that so many modern science programs use now that just distract rather than help inform. :unsure: The money PBS spent is very obvious and while some of CG effects are a bit dated most still look good to great. And the live action historical re-creation sequences are very nicely done. But it's how Sagan takes science and mixes it with society & humanity that makes this series so interesting to me (my much-viewed VHS tapes are almost unwatchable now!). I have seen no other program do it so well. The Big Ideas he describes really made an impression on me back then and still do actually. * that haunting opening theme is by Vangelis; much of the rest of the series uses classical music to help create a great mood for those Big Ideas he discusses.
