About a year and a half ago, I was introduced to Cosmos: A Spacetime Odyssey right before it was about to start airing. The first episode blew my mind. The next few months were spent getting all of my errands out of the way and dinner cooked on Sundays in time to turn the TV on and learn about the universe.
It always baffled me how few people at work had heard of, let alone watched, Cosmos. And when I told them about it, I was stunned still to see their complete lack of reaction.
