James Bowery left a comment on my blog and opened a thread in the Yahoo! group devoted to discussing the mathematics of George Spencer Brown’s Laws of Form. I’ve been meaning to join that discussion as soon as I could work up the time and concentration to think about it — at long last I think I can do that now. I’ll use the above heading to blog any bits from my side of the conversation I think might serve a wider audience.
It’s been a long time since I joined a new discussion group so I thought I’d start by posting a bit of the old-fashioned self-intro.
