The revised version is also great. Most of the content is still the same, a nuclear reactor works just the same way as it did in 1995. But most of the IT topics are updated. Instead of a ball mouse you'll find an optical one, instead of the CRT they explain LCD screens etc.

There's also a "new"(2016) book in the same style but for science instead of technology. It's just as good as you'd expect it to be.
