Exhibitions:

ICIAM July 2003 Sydney, New South Wales, Australia at the Harbour Convention Centre

Provenance:

I gave a negative gaussian curvature (anti-clastic form) carving workshop at COFA/UNSW, the College of Fine Arts at the University of New South Wales. This was attended by very keen students and faculty and was hosted by Professor Bonita Ely and Dean Ian Howard. Three of these brilliant students of negative curvature who completed their own mostly negative curvature carvings were Paul Harris, Francois Limondin, and Noelene Lucas. This piece was featured with a photo of my head in the middle of the piece; this appeared in the Sydney Morning Herald, Tuesday, July 8, 2003, article by Richard Macey.

Special engraving:

sin(tan(t))/(tan(t)), gnamma holes inside the base plane with spirals and connecting lines.

Dimensions:

3" x 3½" x 2½"

Weight:

3 lbs

Materials:

white styrofoam

Price:

available for casting in silicon bronze

The sinc function was the logo for ICIAM Sydney 2003; ICIAM is held every four years, the next one is in Zurich 2007, the International Congress of Industrial and Applied Mathematics. This piece embodies the sinc interpolatory function and cnvolves it with some natural features of the Australasian continent, its geology and marsupials--parabolic trajectories, inselbergs, and gnammas.

A quote from Richard Macey's article in the Sydney Morning Herald, Tuesday, July 8, 2003: " One of his works on show at the maths congress, at the Convention Centre, is an endless circle, an " umbilical torus ". A torus, he explained, was a " a thing with a hole in it. All us mammals are a torus because you eat something and, well . . . People can relate to a torus." Another shape drawing crowds is his "sinc ring". Said Dr. Ferguson: " The sinc function, ubiquitous in industrial and applied mathematics, has infinitely many bumps". He had " organized this infinity of bumps into the since circle, butttressed by a corresponding infinity of parabolic arcs, the trajectory of jumping critters, if you like" ".
