Origin of Net ViewDate: 05/14/2002 at 11:38:18 From: Elizabeth Haverstick Subject: Net View of Pyramids Hi Dr. Math - I am student teaching in a 7th grade classroom and we are studying the volume of pyramids and my students were interested as to why the "exploded" look at the pyramid was called the net view - I was also curious as to where the name came from - whether it had any history or origin. Thanks! Date: 05/14/2002 at 12:13:28 From: Doctor Sarah Subject: Re: Net View of Pyramids Hi Elizabeth - thanks for writing to Dr. Math. In his book _The Words of Mathematics, An Etymological Dictionary of Mathematical Terms Used in English_ (Mathematical Association of America), Steven Schwartzman says: net (noun): a native English word, from the Indo-European root ned- "to bind, to tie." In mathematics a net is a two-dimensional fold-up model of a polyhedron. The faces of the polyhedron appear as connected (= bound) polygons in the net. Each face meets another along a common edge. - Doctor Sarah, The Math Forum http://mathforum.org/dr.math/ |
