"Our NSF grant to integrate mathematics and physics continues to uncover =
new and exciting groung." And very exciting groung it is! If we look =
at a flat Mercator projection of the Earth with the longitude lines =
parallel then we would see our planet as a cylinder. As a three =
dimensional globe, it is of course a cylinder with the top and bottom =
very rounded. We must be very careful to use the correct values for Pi =
because, as those of us who attended the Oregon Trail Band concert at =
the AMATYC Conference learned, rounding can lead to a disastrous gap =
when circling the wagons.

Our NSF grant to integrate mathematics and physics continues
to uncover new and exciting groung. We just learned that
the value of pi squared is roughly equal to the gravitational
constant (average) for the earth (in metric units).
(pi)^2 .=3D. 9.8 m/sec^2

Now we all know many of the relationships between pi and=20
geometry, so we wondered if this relationships shows that
the earth is roughly cylindrical?
