The first release of Our Undiscovered Universe occurred on nullphysics.com on August 6, 2007. I had put off reading any of the copies from the big print run, concerned that I would find a bunch of tiny changes I wanted to make. But I read a copy, and was surprised to discover that after the three years of editing that produced this final copy, I was finally out of edits. No font changes, spacing changes, graph label modifications, or word substitutions were needed. Now all I had to do is wait to see if anybody else liked it.
