""This wonderful book, which is part of the Ponderables history series from Shelter Harbor Press, explores one hundred technological achievements that have changed history, starting with stone technology and ending with solar power. It seems ideal for advanced readers, and I'd probably recommend it for teens to adults...Wonderful, full-color illustrations and side-bar notations enhance the reader's understanding of the material...This fascinating book covers everything from taming fire and irrigation to the Great Wall of China and robots. It's truly a remarkable read. It makes a lovely coffee table book to share with guests, and it's a great conversation starter. It's also one that I reach for when I just have a few minutes to relax and want to read about something stimulating and interesting. I found myself sharing tidbits of information with my children that fascinated them as much as it did me. My high school senior also found it a wonderful book to read at his leisure. I highly recommend it, and I have no doubt you'll enjoy it as much as I have."" - The Old Schoolhouse Magazine(R), LLC, Kelly Burgess
