Spring 2008 Conference of the Mathematical Association of America Seaway Section, hosted by the Syracuse University Mathematics Department, April 11-12, 2008.
The set of Hyperreals *R is known to be an ordered field which is Dedekind incomplete, but how is this incompleteness manifested analytically? The purpose of this presentation is to explore this and other properties of *R and provide some interesting and counter-intuitive results deriving from it. Examples will include the demonstration of holes in *R, as well as proving its failure to be closed under countable additivity.
