eFunda stands for engineering Fundamentals. Its mission is to create an online destination for the engineering community, where working professionals can quickly find concise and reliable information to meet the majority of their daily reference needs.
eFunda is all about the basics, for most part, that means college level material covered in engineering schools. If you practice engineering, more often than not you would find yourself searching for something you knew but could not quite remember. eFunda wants to be your reminder of these formulas. Not only that, eFunda wants to tell you exactly under what conditions those formulas apply, so you don't have to read an entire chapter of the good old textbook.
The engineering world is full of formulas. This is a dangerous thing. Most of us are so used to using a certain formula to solve a familiar problem that we forget that each formula has its limitations. Often neglected are the assumptions taken when the formula was derived in the first place. In engineering, mis-applying a formula sometimes is much worse than not knowing any formula at all. As experienced engineers, the staff of eFunda recognizes this danger and strives to provide the most precise technical information that anyone could find on the web.
Our obsessions are accuracy and simplicity. If we can't summarize a topic in a few pages with the information that you can readily apply to your project at hand, you may as well read a book. Our goal is to save our audience precious time. When we started eFunda in early 1999, such resource was not available. Today, eFunda-like sites are still hard to come across, especially when it comes to quality and coverage. We ask for your approval, and please do not hesitate to write to us for suggestions. Or, if you prefer, you can call us toll-free at 1-800-398-5968. We look forward to hearing from you!
