tl;dr version: delete.
Long version: Alright, this book has been around for quite a while now. I never really knew what to do with it because it's just unfixable. I got tired of seeing it today, so I'm proposing that we send it to book hell.
First, there's a ton of cleanup to do. That in itself is not particularly a problem, but then you get cornered by the scope of the book. There's no way you can give a coherent structure to the book, its scope is just way too large. Basically it's a book about "everything".
For the mathematics of particle physics, one would be better served by a book dedicated to them (aka Book:Representation Theory of Lie Groups & Lie Algebras or Book:Quantum Mechanics or similar). The "matter" part of the universe is already covered by Book:Matter, or if one feels like digging deeper Book:Hadronic Matter or Book:Particles of the Standard Model. For the universe in general, we have Book:Universe (it's not a particularly good book at the moment, but WP:SOFIXIT). This book is basically a badly-ordered mashup of all these books. We currently lack books on say Book:General Relativity, or Book:Cosmology but it's just a matter of time before someone creates them.
So since you can't fix this book, let's just be done with it. Headbomb { talk / contribs / physics / books} 07:07, 26 July 2011 (UTC)
