The Washington D.C. area Mathematica Special Interest Group will meet Friday, 6 March 2009, 7:30 to 9:30 a.m. at the SAIC Enterprise Center building in Tysons Corner (see directions below).

Early risers meet before 7:00 in the morning for admission at the front desk, then we have a Dutch treat breakfast downstairs.  By about 7:30 we have moved to one of the classrooms.  Meetings consist of prepared talks, informal discussion about Mathematica programming and applications, general questions, and new business. 

1.  Prepared Talks:  

A.  Program Evaluation and Review Technique, by Bruce Colletti

Abstract.  PERT is widely used to plan, track, and manage projects, helping to keep these on-time and on-budget (unless the project controls its masters).    After briefly reviewing PERT and the Critical Path Method, we'll discuss familiar ways to estimate project duration.  We'll then examine a new method that overcomes the weaknesses of the old ones.    

B.  A Rotating Plane Exercise, by Dan Martinez.  This presents techniques for basic 3D programming, something we can never know enough about.

C.  Dynamic Horizontal Bar Graph.  Also by Dan, this talk presents a unique view of the terms of office of all US Presidents (President Obama, you have an open invitation to attend our meetings). A general technique for dynamic plotting of time-series data will be illustrated.

Bruce Colletti will present "MathGroup Corner", a summary of the month's highlighted traffic in MathGroup, a forum for Mathematica users (  

To inquire about attending, e-mail Dan Martinez (dmartinez at or Bruce Colletti (bcolletti at  In your e-mail subject line, please include 'Mathematica SIG.'
