Warren, no joking about not having a full bookshelf anymore for research. I entered the field just before the web arrived, and remember getting data sheets the old fashion way. Want to learn about some new product? Oh, you need to look up the manufacture in the Thomas Register (aka "Big Green Books")....
And writing code, especially for Microsoft products? What was a time consuming and difficult process, is now complimented by being able to grab tons of examples off of the internet, along with the reference material right from Microsoft.
Let's see, I also remember using modems to dial into customer machines, sending FAXes to order stuff, etc.
Sometimes I miss being able to use the "I'm compiling right now" excuse.
And since I am a pack rat, I do still have one full set of brand new, still in the box, Texas Instrument logic books (the yellow ones with the blue stripe).... :)
I was particularly intrigued by the simple, yet very effective pinch valves. I was able to go to the site from the link in the author's sig line and learn even more.
Unfortunately, searching on that same site for more information on the Quik-Lok produced no results at all. While I believe that I have a fair idea of how this type of quick disconnect works, it would have been much more informative if the author's website provided that information.
I think it is great the communications we have now. I used to have a shelf FULL of transistor and IC books. Now I have the web and no books. I read Design News, Electronic Products, EDN, etc. and find all sorts of useful things.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
