An electrician I talked with several years ago told me he'd never run out of work. There are enough engineers here to keep him busy for years. These engineers try to rewire their homes and can't figure out what to do. They lack the practical experience to actually wire basic household circuits and make them work. Perhaps they do better at designing ICs or writing code.

Like me, you may attempt few of the projects, but it's worth seeing that amateurs can still do real, hands-on science. Cahners Business Information , a division of Reed Elsevier . All rights reserved.
