New Paradigms for Spiral Tiling . . . .

Waldman Parquet Tilings


This paper introduces spiral tilings possibly never seen before.  In the animation notice the spiral arms can be discontinuous in spite of the fact that they were created in the same way as many other spirals.  They are unique.

A Waldman Parquet Demo



Parquet, or parallelogram substitution, tiling is a new paradigm for radial and spiral tiling.  It is inspired by, but decidedly different than rhombus substitution tiling. We describe the tiles that are suitable for this tiling and how to create them. We demonstrate how to produce radial and spiral tilings with the Goldberg shift.

Historical Sketch

From the legendary Delian problem in antiquity to modern freeway construction, spirals have attracted great mathematical talent.  Among the more famous are Archimedes, Descartes, Bernoulli, Euler, and Fermat, but there are many more whose work has enormously influenced pure mathematics, science and engineering.

The name spiral, where a curve winds outward from a fixed point,  has been extended to curves where the tracing point moves alternately toward and away from the pole, the so-called sinusoidal type.    We find Cayley's Sextic, Tschirnhausen's Cubic, and Lituus' shepherd's (or a bishop's) crook.  Maclaurin, best known for his work on series, discusses spirals in Harmonia Mensurarum (1722).  We find parabolic spirals.  In architecture there is the Ionic capital on a column.  In nature, the spiraled chambered nautilus is associated with the Golden Ratio, which again is associated with the Fibonacci Sequence.
