A publisher asked me today whether I had "any previous publications". There's not much in the way of books, but I was surprised to find that my popular articles in print, on paper, must number around four million copies. That's judging by the number of articles sold, and the circulation of the magazines concerned. It would be a lot higher if one were to include other media. Here are some of my "covers" (pictured) in the electronics press. OBSERVATION: I have been journal published in four fields: electronics, gnomonics, theology, and philosophy.
