Of no apparent relevance to evolution or creation, but anyway:
Musings on the relations between a planets revolving speed (around the sun), it's rotationial speed (around it's own axis) and the length of a day.
Fundimental definitions:
1 year = time it takes planet to complete 1 revolution (360 degrees) around the sun.
The panets year is essentially constant as time passes.
1 day = time it takes a planet to rotate, such that a given point on the planet cycles from facing directly toward the sun, to once again facing directly towards the sun (not necesarily 360 degrees of rotation).
Hypothetical model: The earth, and assuming a slowing rotationial rate (measured in degrees per time, with "days" not being a valid unit of time, since the length of a day is changing) for the earth (which is an accepted concept by mainstream science).
Currently, the earth has a year of essentially 365.25 days, or conversely, an earth day is 1/365.25 years.
In other words, the earth's rotation rate is 365.25 times it's revolvution rate. In one day the earth rotates:
earth day = 360 degrees +
