From Cartoons based on cartoon by: Glenn & Gary McCoy

Over the years, many people have used results from the author's website at no cost and have linked to his pages in blogs, Usenet forums, university forums, personal pages, and books, which you can see by looking at the author's Links section.

All the author's products - except for papers for which the copyright has been transferred to the corresponding journals have been free.

If you are scientifically inclined and find these pages useful in any way, you are welcome to make a donation securely via the PayPal donation button, below. A small donation of €4-5 helps pay rent and the bills.

Alternatively, if you don't feel like donating, you can help by buying any of the products listed in the Amazon ads below my pages, from which, if sold, I get a tiny commission.
