ABSTRACT

For the science of biology, the relevant observations and measurements exclusively concern organisms that are currently living or have once lived on planet Earth. This narrow and perhaps introspective topical focus separates physical biology from many other domains of physics. Humans have been fascinated by the workings of the living world since the dawn of consciousness. Throughout much of the history of human investigation into biological phenomena, the kinds of observations that could be used to develop “views” in the Darwinian sense were limited by difficulty of observation. Even a casual inspection of the biological literature reveals that the results of biological experimentation are often presented in form of graphs that reveal the kind of quantitative functional linkages among different variables that are the lifeblood of physics. The chapter also presents some closing thoughts on the key concepts discussed in the preceding chapters of this book.
