Lead. That was the subject of last night's episode. Who'd have thought that a scientist (actually, an assistant, IIRC) trying to figure out the age of the earth would eventually lead (say: leed) to the reduction of lead (say: led) in the country. Couldn't even test without getting messed-up results until creating a clean room that has NO lead anywhere. Very interesting show.
I really liked this past one (was that Marlee Matlin as the voice of the female astronomer?), with some mythology, some history, some star science.
Really liked this one: ice ages, continental drift, extinctions. By the end of it, the "mystery" of the as-yet named next wing of the Hall of Extinctions seems interesting.
True, but NDT's point was would we cause it or actually be it? Sadly, I'd vote for both.
I think I've posted it before, but this most recent one may be my favorite episode (so far). Early scientist put down by a jealous lesser who happens to be more notable at the time, who doesn't understand "the math" but still gets people to understand concepts.
No surprise, but this week's was a "climate change is real" episode. Handled well, IMHO, but some may take it as somewhat defensive. I really liked how they interspersed Venus' climate details. I did NOT know that Russia landed a probe on Venus' surface to take photos before it melted in the heat.
Next week: last episode, AND the Blu-Ray/DVD comes out Tue. 6/10. I am pretty sure I'll pick up the season, but will FOX or Nat. Geo. do the same for future years?
