I've kept a site called "Technical Tutoring" up for more than 20 years, as an homage to the years I spent tutoring individual people. I think it is time to celebrate this site, as it has helped a lot of people "get" math, chemistry and computers, quickly.
Here is the basic map to the site. There are some broken links that I am fixing as rapidly as I can.
Most of these pages are directed at college students, since those were the vast majority of people I worked with. Gradually, I am working my way down to more basic levels of STEM education.
