Colophon

Colophon

Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects.

The image on the cover of Nokia Smartphone Hacks is tin cans and string. A tin can telephone is probably one of the great joys of youth. It is fairly easy to construct one. It works through the basic physics of sound. When the speaker holds his end of the phone—his can—in front of his mouth and speaks into the can’s open end, the sound waves travel into the can, causing the can to vibrate, which in turn causes the connecting string to vibrate. And so the sound waves travel along the string to the other can. The second can vibrates, and the sound comes out of the can. Simple, yet perfect!
