The Grind

The grind never stops until the force of friction stops it. This in no way means hustling as some may try to define it as. This is a component of physics.

The grind of the rusty cogwheels did not stop until the the force of friction overwhelmed motion.

grind

Used to describe two alternating states common to students and professionals in technical fields: the state of "grinding" for a work/school deadline and the state of "grinding" on the dance floor following completion of said academic/professional responsibilities. This connotation is most often applied to graduate students in doctoral programs, particularly in fields that involve intense computer programming and/or rigorous technical calculations, in which case it is referred to as "the research grind".
