Abstract This paper covers the following topics: what are supernovae; the history of the supernovae; supernovae in our Galaxy: how they are formed; nomenclature; how they affect us.
From the Paper " A supernova is the cataclysmic explosion of a big mass star, which releases a huge quantity of light instantaneously, occurring approximately twice per century. Astronomers have been observing supernovae in our skies since the times of Christian Huygens, Simon Marius, Messier, Brache and Kepler. Fritz Zwicky was the first to use the term supernova to describe lights that were much brighter than any other star or planetary body visible in the sky. "

From the Paper "This is accomplished by demonstrating that a sphere of mass m suspended on a ramp at a height h will have a gravitational potential energy Ug = mgh and that energy will be equal to the total kinetic energy EK = 7/10mv2, where v equals the final velocity of the sphere as it leaves the ramp. Therefore, the law of conservation of mass will be verified by demonstrating the following equation: Ug = mgh = EK = 7/10mv2.
The lab is an original comprehensive work with a full theoretical background of derived equations, and tables and graphs displaying all pertinent experimental data. Several illustrations are also used to convey the details of the experimental method."

Velocity Experiment Using a Thin-Walled Cylinder, 2000. A report on an experiment designed to demonstrate that the radius r of a thin-walled, rigid-body cylinder, when neglecting friction, has no effect upon the velocity of the center of mass vcm of the cylinder down an inclined plane of constant angle q. 1,700 words (approx. 6.8 pages), 2 sources, $ 55.95 »
Click here to show/hide summary
From the Paper "This is accomplished by showing that vcm of the cylinder is a function of gravity g down an inclined plane and the height h of the inclined plane, unaffected by the radius of the cylinder as given in the equation
vcm = (gh)1/2
The lab is an original comprehensive work with a full theoretical background of derived equations, and tables and graphs displaying all pertinent experimental data. "

The Theory of Eliminative Materialism v. Dualism, 2000. This paper attempts to answer major questions pertaining to minds, bodies and existence from the dualist's standpoint and the eliminative materialist's stand point simultaneously. 1,790 words (approx. 7.2 pages), 3 sources, $ 57.95 »
Click here to show/hide summary
From the Paper "The theory of Eliminative Materialism attempts to prove more about the physical world than dualism, and answers more fully questions of metaphysics concerning the point to human existence. The questions of cognitive sciences are general and particular questions addressing issues such as existence and what sorts of things can exist. Then there are the more particular questions like; Is there a soul?, What is the relationship of the soul and the human body, or the mind to the body? I will go over the major questions pertaining to minds, bodies and existence from the dualist?s standpoint and the eliminative materialist?s stand point simultaneously."
