The internet is the greatest invention of mankind. Instanteous access to near infinite current knowledge. It's incredible.
TV is great for consuming your information by watching it, and I do it frequently. I loved
Planet Earth, I've only seen a few episodes of
Life, but it's pretty amazing (visually spectacular, just like
Planet Earth is). I haven't made it through
The Universe yet, but I've been busy. Whenever I see a special on the History Channel or its derivatives (the Military Channel is fun for me), Discovery, etc, I love to watch them.
I tend to do tons of reading online though, where it's easier to fact check. Can't do that on TV, but I hope the producers did their homework.
I think my favorite has been
Planet Earth so far, but
Life is really growing on me. I don't think I've ever seen any of the NOVA series on TV, despite being a huge fan of Neil DeGrasse Tyson (I'm facebook friends with him!)
I enjoy watching TED talks though from
TED: Ideas worth spreading. Brilliant people with brilliant ideas, and a couple of rants now and again. Lets me see what other people are thinking.
