The book is going well I think, like a good string quartet. I want to make a good job of the chapter on photon mass because that was the first major consequence to physics of B(3). Even in the very unlikely event of WS / Imperial breaking contract the book can be published open source, and is sure to attract a very large readership. In fact it can be published open source on www.aias.us alongside the published book format. By experience it has been found that one does not harm the other, provided the publisher has the distribution power. Small presses simply don’t have the power or captive library market. AIAS is the most powerful of all in the relevant field.
