I am back from my sojourn in Hawai’i. It was a great year. I enjoyed being back in the classroom and working with the kids. My wife and I had a whale of a good time. I decided to freshen up the look of the blog with a new format. I have some new post coming in a few days. Meanwhile – or maybe after your vacation – please continue to use the blog. I’ve had over 100,000 hits so far. If you find it helpful, please tell you friends and students (whom I hope are also your friends) about it.
As always, I appreciate your input. Please ask questions and click the “Like” button. I would especially like to know if there is any topic or concept you would like me to discuss or expand on. In the column on the right are various ways of finding what you are looking for. Use the search box or the Posts by Topic list to get started.
