We LOVE this book!
The world of quality science books for very young children is sadly lacking. Mudpies to Magnets definitely fills a huge void. The book is detailed, clear, accurate, and age appropriate. Don't think this book is strictly for young children, older ones enjoy it as well. It really helped reinforce concepts in a real, fun way. If your kids are struggling with science or think its 'boring' you definitely need this book.

I love this book! It is a great introduction to science for young kids, beginning with pre-school age. Sensible focus on asking questions, observing and measuring phenomena. Uses a child's natural curiosity about the world all around and harnesses it to encourage the systematic thought on which science is based. I will be teaching a science class for my daughter's Montessori class every two weeks and will take many (most?) of my lessons from this book!

This book and the original Mudpies to Magnets are my best choices for simple, one-page science activities. These science books and experiments were clearly written with the parent or teacher in mind. Although the books contain a wealth of knowledge and experiments, none of the material is overwhelming for the adult participant. The experiments themselves require only inexpensive, household materials. And each of the experiments that we have tried are fun. One caveat: Ignore the age rankings as a wide variety of children (up to age 10) can enjoy all the experiments in these books...from The Science Spiders(TM) Newsletter.

_Greek and Roman Technology: A Sourcebook_ by Humphrey, Oleson and Sherwood is a fascinating and yet accessible examination of ancient technology in all its aspects. The sourcebook format is particularly well suited to such a diverse topic, and brings the reader closer to the Greeks and Romans in letting us read their own writings about technology. The authors have amassed a spectacular collection of passages from ancient authors on all aspects of ancient technology: the rise of technology and civilization (including some mythical sources), sources of energy and basic mechanical devices, agriculture, food processing, mining, metallurgy, construction engineering, hydraulic engineering, household crafts and workshop production (metals, wood, ceramics, textiles, etc.), transport and trade, record-keeping, and military technology. The final chapter on "Attitudes towards labour, innovation, and technology" is particularly interesting in light of modern issues. The passages themselves are well translated into readable English and are prefaced by short yet very informative introductions on the subject at hand. There seem to be no missing categories I could think of. A short introduction explains the approach of the book, the sources, and contains an essay on "society and technology in antiquity." There are several thorough indices, which make it a handy reference book and source for further study. Anyone who is genuinely interested in the ancient world or the history of science and technology should enjoy this book. It is eminently dippable and can easily be read a few pages at a time. It would make a great present for a well read friend.

Overall, it is easy book to read but you could really tell that each chapter was written by a different person. Some chapters are good but others are really poor. The end of the chapter tests were way too easy compared to the actual test. It has an incredible number of mistakes and typos especially in the calculation of subnet masking. I went round in circles and wasted so much time trying to figure out why I could never get a question correct. I think this book has a second edition that I hope is better. Avoid this book and you will be a much happier person.

OK! I know there are a lot of mistakes...especially for the beginner like me...I am really confused by this book because of its unnecessary mistakes...but, I really like the chapter 2...it's very easy to understand the ARP...IP or ICMP..However, I got confused on the chapter 5 with the wrong route table...Man, I hope it would be better when it come to the second edition!

I am using this book to upgrade my TCP/IP 3.5 to TCP/IP 4.0. I am already a CNE, NCIP, and MCSE. I'm working towards my MCSE+I. This book is a first print (or close to) of a TECHNICAL book. It will have errors! On New Riders' web site, they have a page with corrections which you can print out. I used these corrections as I went through the book. The CONTENT of this book is great and on target. I give four stars because I know from my past education, experience and my knowledge of what is expected on the exam that is book is key! Minus one star for the errors which DON'T affect the content due to the corrections page, but hopefully will be gone in the next print. MCP Magazine also did ratings on the best TCP/IP study book and THIS BOOK WON!
