I've seen De Grasse Tyson on tv before and always found him a bit of a blow hard. Funny at times but basically just spews scientific facts showing off his vast knowledge but to little end. I got the book thinking that perhaps his writing would have more of a point to it but alas it seemed like more of the same. A lot of facts and he does have a good way of explaining things in layman terms. However, most of it seemed disorganized and rambling. The Tao of Physics by Fritjof Capra was much better read for me personally.
