Werner R. Loewenstein

By applying today's information theory to molecular biology, an internationally prominent biologist investigates the sources of nature's organization, from the smallest cell to the human brain, revealing the intricate communication that transpires among cells. UP.

The Touchstone of Life

Though there is a paucity of equations, particularly on the information theoretic side, Loewenstein does a fantastic job of discussing the theory and philosophy of what is going on in the overlapping fields of information theory and microbiology. (I will note that it is commonly held wisdom within publishing, particularly for books for the broader public, that the number of equations in a text is inversely proportional to the number of sales and I'm sure this is the reason for the lack of mathematical substantiation which he could easily have supplied.) 

This is a much more specific and therefore much better - in my mind - book than John Avery's "Information Theory and Evolution" which covers some similar ground. Loewenstein has a much better and more specific grasp of the material in my opinion. Those who feel overwhelmed by Loewenstein may prefer to take a step back to Avery's more facile presentation. 

Loewenstein has a deft ability to describe what is going on and give both an up-close view with many examples as well as a spectacular view of the broader picture - something which is often missing in general science books of this sort. Readers with no mathematical or microbiology background can benefit from it as much as those with more experience.

One thing which sets it apart from much of its competition, even in the broader general science area of non-fiction, is that the author has a quirky - but adept - ability to add some flowery language and analogy to clarify his points. Though many will find this off-putting, it really does add some additional flavor to what might be dry and dull explication to many. His range of background knowledge, philosophy and vocabulary are second only (and possibly even on par or exceeding in some cases) that of Simon Winchester.

I'd highly recommend this book to people prior to their academic studies of biochemistry or molecular cell biology or to budding biomedical engineers prior to their junior year of study. I truly wish I had read this in 1994 myself, but alas it didn't exist until a few years after. I lament that I hadn't picked it up and been able to read it thoroughly until now. 

For my part, his drastically differing viewpoint of the way in which biology should be viewed moving forward, is spot on. I am firmly a member of this new "school". His final chapter on this concept is truly illuminating from a philosophical and theoretical view and I encourage people to read it first instead of last.

I'll also note briefly that I've seen some reviews of this book which make mention of creationism or intelligent design and whether or not proponents of those philosophies feel that Loewenstein's work here supports them or not, particularly since Loewenstein appeared on a panel with Dembski once. I will state for those who take a purely scientific viewpoint of things, that this book is written in full support of evolution and microbiology and doesn't use the concept of "information" to muddy the waters the way many ID arguments are typically made.
