From Clocks to Chaos: The Rhythms of Life

This book is a good introduction for those who would like to learn more about how the rythms of the different processes in our organism work. It requires a good knowledge of mathematics (calculus) but has many examples described in pure text. The analysis focuses mainly in the systemic cycles (heart beat, breathing, etc.) but the same theory can be used to gene regulation and enzime activities. At the end of the book there's an appendix with some basic notions of the math used through out the book but it'll be useful only for those who have some knowledge of calculus.
