In what way is it not rigorous? I've never read it but it definitely seems interesting to have a "good" but non-rigorous science book. Does it just hand-wave over some things to get to other important topics?
I didn’t think so, but it’s the text I used as an undergrad, so I don’t have a basis for comparison. I just have seen that criticism pop up on HN when this topic has arisen in the past.
