Centuries ago the mathmatics to describe the effect of gravity on an object were developed.You are attempting to tell us what the effect of a minimum wage law is in the US in 2010 by referring to a document 15 years old. Not only that, it is not a peer reviewed document, but a document put out by politicians with an axe to grind. The question is:Are you interested in the truth or are you just pushing an agenda?
Perhaps we no longer have an understanding of gravity since our information is centuries old.
Perhaps somewhere along the way objects started falling up and to the side.
Or perhaps some people are attempting to hide behind an overly specific (and ultimately meaningless) question.
