Thanks for dropping by.
I make infrequent contributions, as time and interest permit. My areas of expertise are in physics, mathematics, and technology (more old than new). I'm also privileged to have received a good, solid liberal-arts education, so I've done a fair amount of editing of technical articles, cleaning up their grammar, etc.
Feel free to contact me, if you think there's a page that could benefit from my attention, or just to get in touch with a kindred spirit.
Otherwise, keep up the good work and I'll do the same.
