A little about this site

Who?

Colin Leach. I’m a former scientist (PhD in organic chemisty, career in medical research).

Since retirement I’ve been using the free time to learn more about other branches of science and technology, particularly astrophysics and computer science.

Native of Lancashire, UK citizen, resident of sunny Tucson, Arizona.

Why?

This is all stuff I put together for my own use while learning. It may or may not be interesting to other people, but there seems to be no harm in making it publicly readable.

What next?

Whatever I think of and find time to implement. There is no master plan.
