Pierre Simon de Laplace proposed in 1796 that the solar system was derived from a contracting dust cloud. As the cloud contracts the angular velocity of some particles increases until the centripetal force matches the sun's gravitational attraction. In this way particles of similar angular velocities are concentrated in rings where they soon form into separate planets with circular sidereal orbits. Tidal attraction with the sun causes the proto planets to have the same face always pointing inwards. Subsequent tectonic events provide the planets with their various solar rotations and elliptical orbits around the sun.
	The original dust clouds, and coagulating planets, are near absolute zero temperature at about 3degK. The planets start to heat through radio activity, fission, gravitation effects and the sun's rays. The question is; "How does this rising temperature regime translate into solar rotation"?
