The purpose of this blog is to document my scientific activities - including some speculations and some results. These writings are at a variety of levels - basic to moderately advanced. I enjoy kids' science, and home school a couple of youngsters in science. I'm a student myself, taking part time university courses, and am retired from a technical career in computers. So whatever catches my fancy might show up in this blog. Perhaps some of it will be enjoyable or helpful to others.
