The Geek Atlas strives to highlight sites where you can connect with science and technology. I think it mostly succeeds. Each chapter treats one site, explaining its significance, and includes a sidebar that discusses a scientific principle connected with the site.
For example, the chapter on the museum holding the Spruce Goose talks about the museum and the plane. The sidebar discusses the ground effect. Ground effect increases the lift of a wing flying near the ground, and some experts have argued that the Spruce Goose was only able to lift off because of the ground effect.
I certainly got excited about many of the sites in the book. One example is an astronomical observatory from the 18th century built in India. It was amazing to read about all the things observable using just carvings, pinholes, and sundials. Many chapters similarly highlighted other sites that have a fascinating connection to science and technology.
Some of the other chapters didn't really seem to fit the description of "Places where Science and Technology Come Alive." For instance, Akihabara in Tokyo, which is basically an electronics bazaar, and the Apple headquarters in California, where you can only visit the gift shop.
Entries for Shockley Semiconductor, Fairchild Semiconductor, and the HP garage could be forgiven. Although the first two don't exist anymore and the last can't be entered, still they are places where seminal advances in electronics happened. The statue of Alan Turing sure seems out of place, however, since his achievements could have been included in one of the chapters at Bletchley Park.
One of my other issues with this book is the fact that he wrote multiple chapters for the same site. Bletchley Park has two chapters (one for code breaking, the other for a computing museum) as does White Sands, New Mexico. In some cases, I think he did this to justify the sidebars (probably why the Turing statue is included) and still keep with the overall format of the book. I would have put them in subsections of the same chapter, and still included the sidebars.
Overall, a very enjoyable book, that got me excited about science, deepened my knowledge about some subjects outside my own field, and added a few places to my want to see list.
