This is a great BOOK!!!!-I bought it for my son and he loved it!!Shows kids exactly how to build some really neat things. We won't go wrong with buying this books!!

This book gives a very detailed description along with detailed instructions and hints in order for any person to begin constructing a model railroad. Very interesting to read, never thought this subject could interest me, but after reading it I would like to build a model railroad as a hobby. Captivates you with all the little extra fun things you can do when building a railroad and make it so realistic. Very interesting book. If you're thinking of building a model railroad or have ever thought of building one you must first read this book.

An impressive collection of papers by experts in archeology, cultural geography, history, geophysics, paleoclimatology, etc. on the possible roll of significant climate changes in the roughly simultaneous collapse of the Akkadian Empire, the Old Kingdom in Egypt, the Harappan civilization and various places inbetween. I am not an expert in any of the disciplines listed, but I still found many of the papers interesting. The overall conclusion - that sudden climate change was the explanation for the collapse of civilizations from Anatolia to the Indus - appears to be well supported. I have two reservations. First, if you don't know anything about Bronze Age history, you will be lost starting at page 1. Second, most of the papers are written by experts for experts, and a reader without prior knowledge of rather arcane scientific specialties will have difficulty following some of the papers.
