The Washington D.C. area Mathematica Special Interest Group will meet Friday, 31 October, 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. The prepared talks are: "Eigenvalues and Eigenvectors Associated with Waveguides" by Mel Friedman. The frequencies that are propagated by a rectangular waveguide and the associated modes are explored analytically and numerically with Mathematica. The frequencies that propagate through the waveguide and the associated mode shapes are related to eigenvalues and eigenvectors found using Mathematica. Although not done here, the numerical approach could be extended to other geometries where analytical calculations are not possible. This example illustrates a finite difference technique that can be used to explore the properties of waveguides. "DynamicModule Tricks" by Dan Martinez. Our local Mathematica magician will take us Trick 'o Treating through Mathematica's frightful swamp of dynamic programming. Bruce Colletti will present "MathGroup Corner", a summary of the month's highlighted traffic in MathGroup, a forum for Mathematica users (groups.google.com/group/comp.soft-sys.math.mathematica). Bruce and Dan will recap last week's International Mathematica User Conference. You can also read the Champaign News-Gazette story "Expansion Ahead" about Wolfram Research: www.news-gazette.com/business/2008/10/26/wolfram_research_founder_projects_further_growth To inquire about attending, e-mail Dan Martinez (dmartinez at sprintmail.com) or Bruce Colletti (bcolletti at compuserve.com). In your e-mail subject line, please include 'Mathematica SIG.' The SIG-site is http://web.mac.com/hrbishop.pmsi/DCSIG.m/DCSIG.html 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.
