 Subject: [Lisp] Lisp Meeting: Nov 10th 7:00 at Trinity

 Join us Tuesday, Nov 10th from 7:00 - 9:00 at Trinity Lutheran for 
 Gershom Bazerman's presentation:

 Simple Scheme for Tricky Differentials

 Gershom Bazerman demonstrates an novel and elegant approach to modeling 
 differential equations in functional languages.

 Lazy splines can provide a clean way of expressing ordinary differential 
 equations and deriving numeric solutions.  Unlike standard solvers, 
 equations can be expressed simply and declaratively, as first class data 
 in the target language (Scheme, Lisp, Haskell, etc.).  Differential 
 equations can thus be turned directly into  easily readable and 
 maintainable programs.

 Differential equations have wide applicability -- from finance to 
 physics to computer games. This presentation will be of interest to 
 those who deal with calculus every day, as well as those who haven't 
 seen an integral since high school. A short primer/review of 
 differential equations will be included, as well as a discussion of the 
 power of lazy evaluation and infinite streams in general.

 Gershom is a Haskell developer in New York City, working in the finance 

 Directions to Trinity:

   Trinity Lutheran
   602 E. 9th St. & Ave B., on Tompkins Square Park

   From N,R,Q,W (8th Street NYU Stop) and the 4,5 (Astor Street Stop):
     Walk East 4 blocks on St. Marks, cross Tompkins Square Park.

   From F&V (2nd Ave Stop):
     Walk E one or two blocks, turn north for 8 short blocks

   From L (1st Ave Stop):
     Walk E one block, turn sounth for 5 short blocks

   The M9 bus line drops you off at the doorstep and the M15 is near get
   off on St. Marks & 1st)

   To get there by car, take the FDR (East River Drive) to Houston then
   go NW till you're at 9th & B.  Week-night parking isn't bad at all,
   but if you're paranoid about your Caddy or in a hurry, there is a
   parking garage on 9th between 1st and 3rd Ave.
