Date: Tue, 03 Nov 2009 10:40:32 -0500 From: heow To: LISP NYC 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 sector. http://en.wikipedia.org/wiki/Ordinary_differential_equation Directions to Trinity: Trinity Lutheran 602 E. 9th St. & Ave B., on Tompkins Square Park http://trinitylowereastside.org/ 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. _______________________________________________ Lisp mailing list Lisp@lispnyc.org http://www.lispnyc.org:8080/mailman/listinfo/lisp
