A Few Stars Short of a Constellation . I recently purchased this book and was somewhat disappointed when I sat down to read it. The subtitle is &quot;Games &amp; Puzzles to Stimulate Your Creativity &amp; Imagination&quot;. Actually, there are only some  thirty such puzzles and many of them are 'old chestnuts'. However, my  biggest complaint is the lack of accuracy. The very first puzzle (p. 20)  has a mistake in it. Then in 'Mental Counting' (p. 161), the author claims  that the letters O and U are not symmetrical about the vertical axis. As  for 'Three-dimesional Dots' (p. 199) the text states &quot;Below is a  collection of random dots.&quot; Unfortunately, the random dots have been  omitted. So much for &quot;something remarkable&quot; happening as the  author claims. And how's this for one of the three (yup, only three)  lateral thinking puzzles? What common word begins with IS, ends with ND,  and has LA in the middle? I bet that really stretched your brain, didn't  it? Sorry, but Mr. Wujec's editor should be fired. These glaring mistakes  and omissions have scuttled any enjoyment I may have expected from this  book. I suspect the author was motivated by the commercial success of his  previous book. He should have waited until he had something of value before  publishing this schlock

What we know about constraints on population growth . Obviously, the population of the world has been growing dramatically for the past few centuries.  How high can it go?  At how high a level can it be maintained?   What restrictions are placed by the available resources, such as food and water?      This book asks many of the right questions.  And it admits that we don't have all the answers.  But it does give some clues about where we may be headed.    Cohen shows that basically, if we want to support people indefinitely on 3500 kilocalories per day from wheat energy, with 9000 cubic kilometers of annual fresh water supply, well, we can support only 5 billion people.  We're already beyond that.  Right now, we're using up resources at an incredible rate.  And while the Earth could support 10 billion people in theory, it is hard to see how it could do that for long in practice.    The author thinks that we'll never get to the absolute maximum that the Earth can support.  Most people would all be right on the edge of starvation, and we'd simply be unable and unwilling to stay in that state indefinitely.  But I did realize after reading this book that we could stay at about 5 billion people for a very long time if we put our minds to it.  Standards of living would not be high, but they would be tolerable for the majority, and the ones who found such a life acceptable would keep having children who found it acceptable.    Those of us who have political views ought to wonder if time is on our side or not.  And that is why I think it makes sense to try to imagine what options are available for our mutual future.  That's why I think this book is worth reading

Incredible series! . All the Enchanted Forest Chronicles are so much fun!  Definitely at my top of Harry Potter fan recommendations.  They're just such an amusing read; I even teach with them.  Don't forget to read "The Frying Pan of Doom.
