Clockwise & Counterclockwise Sundial Shadows: Part II

Below are a few more videos that portray the clockwise and counterclockwise dynamics of the Earth and of the sundial's shadow. [Link to Part I] The first shows the Earth rotating and orbiting counterclockwise (looking down upon the North Pole). The second video shows the arc of a sundial shadow (in the Northern Hemisphere) moving clockwise. The third is a more historical look at time and at how it is measured. The fourth is another look at the sundial's moving shadow, using a person as the gnomon (the part of a sundial that casts the shadow).
