Shows the Ways, But Not Much of the Means
on February 28, 2013
The first chapters of this book give a very basic understanding of how information is impressed onto energy waves and transmitted. But after that, most of the chapters just show the paths along which information waves are routed.
The book consists of beautiful, glossy illustrations, with most of the text being simply captions to these illustrations. But the illustrations don’t provide any real understanding of how the process works. Again, you’ll see the paths that the waves are made to follow, but you won’t see any of the inner workings of the different components of the process. You’ll see waves radiating from a glossy colored cell phone – traveling to a brown box representing a gateway – from there to a gray box representing a relay station – and so forth into the glossy colored illustration of the receiving cell phone. If you are looking for some enlightenment about what goes on electronically in each of these way stations – you won’t find much of that here. You’ll also have to wend your own way along a course of a lot of acronyms – from EMF to IPO.
However, there is a good glossary at the end of the book where you can find definitions of basic terms and where you can be reminded of what all the acronyms represent.
This book would provide a good, eye-catching overview for youngsters, or for adults who just want an introduction to the paths information follows in getting from place to place.
