NOTICE: IN 2015 this site will get a complete makeover.  You will have to go to directly in order to see new directory.

Teachers who are using any part this site for teaching a class please email me at address below, and I will contact you when I have completed my new site.  If you wish to include URL of page or pages that you use, than I will restore them ASAP for your benefit.  







My shops are really a small selection of Amazon Products that I feel would be of interest to viewers of my sites.  Select any item that you even have a slight interest in and you will be linked to an Amazon page with the item and a wider variety of models and related products.  Anything you buy at Amazon even music CD's will result in a small commission all of which will help support my free online eBooks.  





New! ( Fall 2007) Get Bill's Free book Force Fields.  A E&M physics primer for electronics students. Download Zipped PDF file: Click Here!
