An LKL Maths-Art Seminar

by Kate Mackrell

Tuesday 13 April, 6.00 – 7.30pm

The connections between art and static geometry are rich, diverse, and

well known. Less well known are the possibilities that can arise when

representations of geometric objects are set in motion. Dynamic geometry

software, widely used to facilitate geometry learning in schools, is a

powerful means to achieve this. Even starting from simple initial

situations, beautiful objects emerge, evolve, and transform, and not

only in cases where this might be expected, such as wallpaper patterns,

or stellations, but also in cases, such as truncated polyhedra, where

nothing new is expected, or in solving loci problems or modeling

physical phenomena. The mathematics to create the objects ranges from

quite straightforward, to approximately A level. The mathematics to

understand the objects – well, that’s another story. The software that I

use is Cabri II Plus, Geometer’s Sketchpad, Cabri 3D, and Cinderella.

[See www.lkl.ac.uk/events/maths-art for links to examples of dynamic

art.]

KATE MACKRELL has been playing with geometrical objects ever since her

brothers got their first Lego, and with computers ever since the days

when programs lived on punch cards. After a Master’s degree in general

relativity, she did computer programming before becoming a secondary

school teacher and then working in secondary teacher education. She is

currently doing an M.Phil in mathematics education at the Institute of

Education, exploring ways to facilitate early secondary students in

using Cabri 3D to do creative mathematics.

TIME: 6.00 – 7.30pm, Tuesday 13 April 2010

PLACE: London Knowledge Lab, 23-29 Emerald St, London, WC1N 3QS

The current “De Stijl” exhibition at Tate Modern in London has a 2000 computer video reconstruction of Bauhaus artist Ludwig Hirschfield-Mack’s “Farben-Licht-Spiele” (Colour-Light-Play) from 1923-4. Hirschfield-Mack invented apparatus to display simple 2D geometric shapes (triangles, circles, etc) in different colours slowly shrinking, expanding and changing colours over time. The computer reconstruction is very powerful and hypnotic.
