'An up-close, inside look at how things work'. Nobody does this type of book better than Dorling Kindersley. It takes a fascinating look into some of the wonders of our modern age, and many less modern marvels too. Glowsticks, barcodes, lava lamps, fireworks, thermal imaging, wind turbines..these are just a few of the inventions covered. Each is clearly described, with the science behind it explained and an explanation of how it is used given. Although I have identified the book as being for 7 - 11 year olds, it will appeal to anyone with a curiosity for the world around us. Attractive layout and a multitude of photos and diagrams help us all to appreciate the wonderful discoveries and the world around us.
