Welcome to our Blog

More than a Blog, A Place to Learn, Share, and Laugh a Bit

We started an email newsletter back in 2002 as “The Focus.”  We kept that up for some time and then made the plunge into blogging around 2008. Over the years, thousands of students and engineers from around the world have told us that our blog is an invaluable tool to them. If you can’t find what you are looking for, don’t hesitate to contact us.
