excellent non-mathematical text
I bought the 2012 edition, custom printed for a particular university, which turns out to be in 3-ring binder format. I'm getting back into astronomy and wanted a review, it's been 40 years since I took it as an undergrad. This text is very readable, paper is thin but print quality excellent. I was expecting a treatment with more mathematical rigor, but as a result this is more of a fun read. This is a non-science major's text. It is very well written and better yet, written in an interesting fashion with good historical side notes. That makes it fun to read as well as comprehensible. Very little science or math background is assumed or necessary. There are extensive illustrations, generally very well done.
