About ten years ago, I decided to try to learn electronics so I could build my own amps. I bought a book called Electronics Made Simple. A week later, I had to buy a book called Mathematics Made Simple. It seemed I couldn't learn electronics without mastering some math concepts. Woe to a misspent youth! If I could have bought Kenn Amdahl's book There Are No Electrons: Electronics for Earthlings, I would have known that an amateur can understand electronics better than a pro-without doing a single calculation. When someone suggested that I review a book where the tireless "need to party" of imaginary beings called "little greenies'' represented voltage, I thought I was hitting a premature journalistic bottom. To my surprise, I learned an amazing amount rethinking what I already knew, things that I had learned the hard way. It works like this: the chicks buy the kegs of beer and turn up their radios. The brothers hear that rock and roll, get in their little green cars, and motivate toward the music. That's current.
