Physics is the study of the basic laws that govern matter. Physics covers the science of the very large, and includes the study of bodies in motion, forces, heat and ...

Study the tiny molecular motors that cells use to produce force and motion in human cells. To break symmetry, all cells polarize making one part of the cell structurally, functionally, or ...
