1 The Society for Experimental Mechanics maintains a series of downloadable articles on its Web site. The articles include titles devoted to strain gauges, dynamic strain measurement, automotive applications, modal analysis, and structural integrity, among others.

All are available as PDFs. Check out the site and brush up on your experimental know-how. load.asp

2 Sure, you could visit or Weather Underground or other sites to get your weather info, but why not go to the source, the National Weather Service? The site is extremely well laid out and has so much wonderful information! You can view current weather alerts, radar maps, as well as your local climate conditions. If you click on your state from the national map on the home page you can view detailed wind conditions, cloud cover, dew point, snow, and current forecast. Did I mention the historical weather data also available? Wow.

3 I think we've established that I (a.) love the Web and (b.) have a lamentably twisted sense of humor. Now, I have added a new arrow in my quiver of Web-based trivia skills: the ability to say "My God! I have an axe in my head!" in 112 languages ranging from the basic (Spanish, French, various German dialects) through the obscure (Ancient Egyptian hieroglyphics, Basque, Cree, Hausa), all the way to the manufactured (Klingon and Sauron's Black Speech of Mordor). There's even an axe-in-head smiley! k:-O

Foundations of Analog and Digital Electronic Circuits

Authors: Anant Agarwal and Jeffrey H. Lang

Publisher: Morgan Kaufmann Publishers, an imprint of Elsevier

ISBN: 1-55860-735-8

Field-tested on MIT's sophomores in electrical engineering and computer science, this softcover book blends circuit analysis and basic electronic circuits, putting the circuit networks discussed into practical context.

The book is divided into sixteen chapters and four appendices. The chapters include material on circuit representation and abstraction, resistive networks, network theorems, analysis of nonlinear circuits, digital circuit representation and abstraction, small-signal discipline (restricting signals to small perturbations about an operating point so that the circuit's response to the perturbations is linear), energy storage elements, energy and power in digital circuits, transients in second-order circuits, impedance and frequency response, resonance, op amps, and diodes.
