Dence, Thomas P.; Heath, Steven – Mathematics and Computer Education, 2005
The number Pi has a rich and colorful history. The origin of Pi dates back to when Greek mathematicians realized that the ratio of the circumference to the diameter is the same for all circles. One is most familiar with many of its applications to geometry, analysis, probability, and number theory. This paper demonstrates several examples of how…

On the Beauty of Mathematics as Exemplified by a Problem in Combinatorics.
Peer reviewed Peer reviewed
Dence, Thomas P. – Mathematics and Computer Education, 1982
The beauty of discovering some simple yet elegant proof either to something new or to an already established fact is discussed. A combinatorial problem that deals with covering a checkerboard with dominoes is presented as a starting point for individual investigation of similar problems. (MP)
