Living organisms are distinct from inanimate matter in their unique ability to produce purposeful, directed movement.  I will present data from optical and force microscopy studies of the motions produced by single proteins, networks of proteins and whole cells.  Using an ultra-stable optical trapping instrument capable of measuring angstrom-level translocations in three-dimensions, we have been able to study a variety of biological systems in unprecedented detail.  These fascinating systems lie at the interface between biology, chemistry and physics and their study requires the development of a new set of tools that can be readily combined with traditional techniques.
