Began reading this around Thanksgiving and wrapped up this week. I watched a few episodes of the show and have always wanted to read one of Tyson's books. I have another sitting on the nightstand and will probably spend 2015 reading through his work the way I did Malcolm Gladwell's last year. There were a few "dosing off in science class" moments, but those moments were few. It's not good for me to spend a lot of time thinking of the vast universe because I get depressed easily, but Tyson leads you to believe it's not something to be afraid of.
