CIRCLES: PACKINGS AND MIRRORS
An LKL Maths-Art Seminar
by
Alan Sutcliffe and John Sharp
Tuesday 9 March, 6.00 - 7.30pm
This month's seminar is a two-parter on different aspects of circle geometry.
Alan Sutcliffe 'Hexlets: when circles collide' A hexlet is a
configuration of six touching circles surrounding a seventh central one.
After a brief history of hexlets, including their role in some Doyle
spiral circle packings, two sub-types are described where circles in a
hexlet collide although they are not neighbours. This leads to other
forms of circle packing which are presented with a little maths, and
their behaviour shown in simple animations. I will use these hexlets to
make some graphics and a small work of animated art.
John Sharp 'Inversion: the circle as a mirror' There is a well known
transformation which maps the outside of a circle to the inside and vice
versa. Lines map to circles. I will review the geometry of inversion and
show some ways inversion has been used in mathematical art, including
the work of John Pickering. Finally I will present some recent work on
how a specially shaped inverting mirror can create anamorphic images
(that is, 'secret' distorted images which are revealed by reflection in
a mirror surface).
ALAN SUTCLIFFE has been a key figure in computer art and computer music
since the 1960s; he was a founding member of the Computer Arts Society
( www.computer-arts-society.org ). JOHN SHARP is a researcher, writer
and teacher on mathematics and art, and is well-known for the sculptural
forms known as sliceforms and D-forms, and for anamorphosis.
