We Revolve

Revolution comes from the Latin verb revolvere meaning to revolve. Revolution was originally applied to the motions of planets.

Revolution was fundamental to Copernicus' world-changing heliocentric model of planetary movement. Copernican heliocentrism was outlined in Copernicus' treatise On the Revolutions of the Heavenly Spheres (De revolutionibus orbium coelestium), published in 1543.

Copernicus' model is noteworthy because it displaced Earth from the center of the uni­verse and offered an alternative to Ptolemy's geocentric model proposed in the 2nd century AD.

That revolution is now the mental hook in the advertising vinyl wrap on the light rail car I'm about to board shouldn't discourage us from revolution.
