A listing of publications where I have authored or I am mentioned or have images of my works, with books, articles and newspapers. Although I have written extensively on the web, the converse is true on the more traditional media, as above. This essentially reflects my nature, of beginning something, and then taking the project to a near state of completion for publication, before essentially becoming distracted by new studies, with the newness or novelty aspect thus gaining traction, resulting in the old being put aside. The delight of the web is of eternal revision, and of which I thus take the opportunity when appropriate. Incomplete, or partial research grates on me. I certainly do not favour publish or perish! Instead, I follow the maxim of the renowned mathematician Carl Gauss, ‘pauca sed matura’ (few, but ripe), and he didn't do too badly for himself! Not that for one moment do I imply our respective works are of equal value; that would be risible! Further, Gauss summarized his views on the pursuit of knowledge in a letter to Farkas Bolyai dated 2 September 1808, and of which I very much concur:

It is not knowledge, but the act of learning, not possession but the act of getting there, which grants the greatest enjoyment. When I have clarified and exhausted a subject, then I turn away from it, in order to go into darkness again. The never-satisfied man is so strange; if he has completed a structure, then it is not in order to dwell in it peacefully, but in order to begin another. I imagine the world conqueror must feel thus, who, after one kingdom is scarcely conquered, stretches out his arms for others.

In short, it's the thrill of the chase that excites me and not the kill, hence the lack of publications. That said, I do have articles nearing completion, on the Cairo tiling (after 30 years of study!), Cluster Puzzles and Houndstooth. And then there’s ‘The Book’, with text taken from my numerous essays where I set out my thoughts (with ultimately publication in mind). However, whether this will ever appear is in doubt. No publisher is beating a path to my door. If it does appear, it will probably be of a vanity project. 

Although I have so far favoured the web, this to me is just an intermediary stage before publication in print. Print has stood the test of time, the defining standard of writing, whereas websites come and go, in effect the blink of an eye. Indeed, as this one surely will one day, in just a few years, upon my demise with the ending of paying web hosting fees. Articles and books, at the age of 60, I really should get on with it!

An art and design book for 11-16 age children. Features my bird and fish tessellation, p. 85. The text (including Magritte’s Decalcomania), accompanying my piece is Freaker and Parsons' own, which is not made explicit, of which I do not entirely agree with, and of which I had no input. Specifically, this involves ‘The Bailey image also (alluding to Magritte) presents an impossible situation’. Admittedly, the (tessellation) situation is highly unlikely, in more ways than one, but not impossible! I’d have preferred ‘highly unlikely’ or a similar expression.

Name check, with a mention of my Penrose thick and thin rhombi page in the References, p. 264, although I am at a loss as to why! Although Le uses the thick and thin rhombi in his article, there is no other linkage between my more ‘correct’ usage of tessellation as an Escher-like tiling and his much ‘decorative’ looser space-filling use.
