h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

"The Design of Everyday Things" is a fun-to-read book with serious insights into design. Mr. Norman is all over that business of pulling on a "push" door handle. There's an amazing story about someone getting stuck in a city building between two sets of inner and outer doors. The doors were all unlocked, and others were going in and out of nearby doors in same entryway at the time. The problem was the modern-look doors gave no indication of which side to push and which side the hinges were.

I second that recommendation. It's a wonderful book that will cause you to never look at a door or a stove or a computer or a telephone the same way again. You can also find it under the title "The Psychology of Everyday Things" which is a more appropriate title, but his publisher made him change it.
