	Elliptical Galaxies (Site not responding. Last check: 2007-11-07)
		Elliptical galaxies constitute approximately 10% of observed galaxies.
		Some other examples of elliptical galaxies include M32, which is an E2 dwarf elliptical near the Andromeda Galaxy, and the E6 elliptical galaxy M110, another satellite of the Andromeda Galaxy.
		Elliptical galaxies exhibit far less evidence for young stars, gas, or dust than do spiral galaxies, and have larger random motion of stars than in spiral galaxies where the motion is a more ordered rotation.

	Elliptical Trainers
		Elliptical trainers combine the natural stride treadmill and the simplicity of a stair climber.
		In its most rudimentary form, Elliptical Technology consists of a crank arm (similar to the crank of a bicycle) that revolves around an axis at one end and that is attached to a bar at the other.
		The exercise experienced on elliptical machines is weight bearing (versus exercise bikes) which has ramification in the inhibition of the onset of osteoporosis.

		The velocity ratio resulting from elliptical gears varies between 1/K and K during one cycle of speed change, where K is the maximum gear ratio.
		In appropriate situations, elliptical gears may be cascaded to obtain varying speed-change characteristics, giving an effective ratio of from 1 to K^2.
