“Also of Interest” for April 23, 2012

Each week, the editor of Planet Analog finds technical items of interest and highlights them in this “Also of Interest” feature. In addition, we also provide an archive of recent weekly Planet Analog Newsletters, viewable as pdf files; see the list at the very bottom.

The “Also of Interest” listing is the embodiment of our belief that engineers are interested in exploring topics which are not directly related to their jobs, but which will broaden their knowledge and sometimes spur further innovative and creative approaches.

Among the publications we check are IEEE Spectrum , Machine Design , Design News , Laser Focus World , Photonics Spectra , NASA Tech Briefs (in its various manifestations), Microwave Journal , RF & Microwaves , and Physics Today —and there are others, as well.

Consider these items as online “extras”, and worth a look and a few minutes of your time. (Please note: there are also links to the past weeks' editions of this feature, in the “Navigate” box to the right.)
