See generally Laura W. Morgan, Child Support Guidelines: Interpretation and Application Â§ 4.05 (Supp. 1999). Many states rewrote their emancipation statutes in the 1970s and 1980s to provide that a parent is released from a child support obligation when the child is 19 or graduates from high school. [See Table below.] Emancipation may also come before the age or event stated in the above Table.
The Law of Conservation of Mass (or Matter) in a chemical reaction can be stated thus: In a chemical reaction, matter is neither created nor destroyed. It was discovered by Antoine Laurent Lavoisier (1743-94) [15K GIF] about 1785.
Galileo discovered the law during the first decade of the seventeenth century, but in fact he did not understand the law in the general way we have formulated it here. The general formulation of the law of inertia was devised by Galileo's pupils and by Descartes-a French philosopher, mathematician and physicist. This law is also the first of Newton's three laws. Up to the time of Galileo, it was thought that one must exert force in order to cause and preserve motion, as claimed by the physics of Aristotle. Indeed, when we look at the world surrounding us, we see that in order to continue movement we must exert force.
