For a book, the Preface is roughly equivalent to the About page for a Website or Blog. And since this site is being organized a bit like a book I am calling this page the Preface.
Although this site does have a blog component that records thoughts as they occur (and displays them in the usual reverse chronological order), the main body of its content here will be organized by topic and accessible via the menu on the left.
So, what’s it for?
Well, it’s just where I’ll be collecting various materials and links that I wrote or collected in my thirty odd years of teaching mathematics – and which I hope may be useful to others (especially in times when face-to-face instruction has been disrupted – forcing many people to maybe need additional resources in order to catch up).
