Shape of earths gravity field is found from satellite orbits. Attraction of
earths non-spherical gravity on a satellite is not toward its center:
This non-spherical gravity field produces effects on satellite orbits:
These 3-D shapes are called spherical
Kepler first described how the intensity of light diminishes by
the inverse-square of distance from the source.
The speed of light was first determined by Danish astronomer

CLASS TIME, LOCATION: Mon. - Thu. 2:30-4:25 PM, DRL Room A4
INSTRUCTOR: Dr. M. Struble, DRL 2C5, Office Hours: Mon., Wed. 4:30-5:30 PM, & by appointment.
Ideas of earth attracting objects can be traced to the Greeks, as well as celestial objects
acting as multiple centers of gravity; Archimedes attributed the spherical shape of earth,
moon and sun to their own separate gravities.
