Mathematica SIG (Washington DC Area)

  • Subject: [mg86957] Mathematica SIG (Washington DC Area)
  • From: Bruce Colletti <vze269bv at>

The Washington D.C. area Mathematica Special Interest Group will meet Friday, 28 March, 7:30 to 9:00 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 projector rooms. Meetings consist of a prepared talk, informal discussion about Mathematica programming and applications, general questions, and new business. 
1.  Talks:

In "Group Theory and Confidence Intervals", Bruce Colletti uses group theory to build a confidence interval for the mean of a random variable that is symmetric about its mean but whose distribution is unknown.  The underlying random sample need not be large.

Dave Vasholz will present "Puzzles and Mathematica: From Ancient Greeks to Modern Geeks."  

Mel Friedman will give a "Mystery Presentation" taken from:

- Reading information into Mathematica from Excel
- Using Mathematica to compute convolution and correlation integrals
- Using Mathematica to compute Fourier Transforms
- Using Mathematica to integrate numerically-defined functions
- Using Mathematica for non-linear least squares
Dan Martinez will showcase his "dial programming hustle" that demonstrates an analog depiction of multiple time-series data sets.  What we'll see should be in our Mathematica repertoire.

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.' 

DIRECTIONS to 8301 Greensboro Drive, McLean VA (tall, boxy and white SAIC Enterprise Building at the corner of Westpark Drive and Greensboro Drive):  From the Beltway, go northwest on Route 7 (Leesburg Pike) and proceed past Route 123 (Chain Bridge Road).  Turn right onto Westpark Drive (Gosnell Road in the other direction).  Turn right  at the next light onto Greensboro Drive and then right into the parking lot. Visitor's Parking is adjacent to Westpark Drive.   

A SIG representative will meet you in the lobby. 

Please arrive no later than ten minutes to seven if you wish to join us for breakfast, and no later than twenty after seven to attend the meeting only.  The desk officer will ask for a driver's license before issuing a visitor's badge.
