Phenomena unfold on their own appropriate scales of space and time and may be invisible in our myopic world of dimensions assessed by comparison with human height and times metered by human lifespans. So much of accumulating importance at earthly scales […] is invisible by the measuring rod of a human life. So much that matters to particles in the microscopic world of molecules […] either averages out to stability at our scale or simply stands below our limits of perception.stephen jay gould
