Good stuff - Bad stuff

The universe is composed of uncountable numbers of discrete masses of
material matter: We are taught early in life that some of these things
are very bad for us, and some are very good for us; or else we start to
learn the hard way, by ourselves; empirically.

The uncountable masses are all in motion relative to each other, and we
are taught and learn to keep out of harms way; that some motion is
good, and some is bad: We can make and control motion that helps us to
accomplish our tasks, and we can make violent motion that is very
destructive.

Mechanics is the science of matter in motion, and we will do well to
study, and understand all we can about it; to examine, measure and
interprete the data furnished by natu Keeping in mind that nature's
secrets aren't easily devulged, and sometimes are misleading.
