Query: Too dumbed down

I do not enjoy giving a book low ratings, but I cannot recommend this book. However I will acknowledge some of you may find it a good read and I urge you to try it if you have reason to think so.Descriptions and explanations appear to be designed to include readers who have NO math knowledge. The author actually apologizes when he mentions that gravity decreases with the inverse square of distance.In my opinion, the time-gravity examples that are more difficult and less interesting ideas than the more famous examples that are usually covered. I think the author felt these example required too much math understanding which he was avoiding, but I strongly disagree.The author seems to think ANY math is too much. But he does not set the stage by explaining the elementary ideas of velocity, acceleration, or Newton's laws.There are much more compelling (and enjoyable) treatments available than this one.
