Subject: For top list From: "Ronnie Brown" Date: Mon, 19 Mar 2007 21:34:14 -0000 My article Out of Line, Royal Institution Proceedings, 64 (1992) 207-243. of a presentation for a general audience is not so easily available, so we have made it into a web article: http://www.bangor.ac.uk/r.brown/outofline/out-home.html The title reflects the idea of Higher Dimensional Algebra and also the general status of this area of research, at least at the time. Referees of grant proposals wrote that this area was `irrelevant to mainstream algebraic topology' , whereas we judged we were constructing a new channel from the intuitive sources of the subject, and the article is intended to show these sources. In any case, we all know that `mainstream' flaps around like a sail on a yacht (to mix metaphors a bit). Ronnie Brown
