Categorists: I just delivered the raw manuscript for my book "Mathematical Mechanics: From Particle to Muscle" to World Scientific. The editor assigned to the project replied, "Please solicit comments from your contacts, but please send us the amendments in the next month or so, before we rapidly move to press." The book offers to high school mathematical science teachers a categorical, diagram-oriented ground and foundation for mathematics directed towards biological research on muscle contraction. A central part of the book is a new algebraic framework for chemical thermodynamics. For example, Hess' Law is a monoidal functor. Adjoint functors are not explicitly treated, but key examples are relevant, such as the construction of the free category on a directed graph. My approach to physics is partly inspired by the work of Christopher Isham et al on the topos-theoretic foundations of physics. Although it is not explicitly stated, all calculations and proofs are meant to be understood in that spirit. The manuscript is available for download at http://www.distancedrawing.com/MathMech.110102a.pdf http://www.distancedrawing.com/MathMech.110102a.ps and I solicit your comments. Note that Adobe Reader X allows commenting with "Sticky Notes," but any means to provide feedback that you care to employ might help me avoid abominable errors of omission or commission. Many thanks, Ellis D. Cooper [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
