I saw the 4th episode last night but was disappointed.
Why do they keep showing science that has already been shown by others many years ago and most people should know by now?
They should show some of the new sciences and possibilities that are new to us and not treat us like schoolboys or schoolgirls.
Specifically because many people...DON"T know this science that 'everyone' should know by now, even the basic principals. (what was it, 20-some percent of Americans still think the sun revolves around the earth? I mean come on.....grade-school level stuff and 1 in 5 people don't know this?!?!)
Cosmos is not a science show for the hard-core science geeks (come on....it airs first on Fox).....it's a science show to get non-science or general-science people more interested in science. Or introduce them to ideas that they didn't know.
After the first episode.....I heard a lot of people where I work saying "Wow! That Cosmic calendar thing was cool!" And I work in an office with lots of science/engineering based people. They hadn't been exposed to thinking about time, and our place in time on a grand scale.
