Spirals, Ferns, and Universal Unfolding Motifs

Thursday, 1 December 2022 by Bruce Rawles

While I try not to obsess about geometric forms, I do observe when certain motifs appear more frequently in various locales. When we visited San Miguel de Allende, Mexico earlier this year, I noticed an abundance of small stellated dodecahedra (and similar shapes) particularly evident in metal lamps, yet also in other art forms as well; each pentagonal pyramidal stellation arm encodes the golden ratio. …

Having just returned from a second visit to New Zealand, it seemed that one of the most ubiquitous geometric shapes we saw on this trip was the spiral, which appears in Maori jewelry, carving, tattoos, art, and culture, connecting the natural world with the art of the indigenous people of Aotearoa. Below I made a mirrored tiling pattern from an image of an unfurling silver fern frond which exhibits an excellent example of fractal geometry.

Wikipedia says “The koru is a spiral shape based on the appearance of a new unfurling silver fern frond. It is an integral symbol in Māori art, carving, and tattooing, where it symbolizes new life, growth, strength, and peace.”

Reflecting intuitively on our spiral “journey” through life like the homeward trajectory Dorothy embarks upon in the Wizard of Oz when she follows the yellow brick road, we find context in the cyclical, yet ever-evolving, ever-unfolding awareness with each revolution of the spiral. In three dimensions, we have the double helix of the DNA molecule in everything we typically call life in this world, embodying the golden ratio in each pentagonal molecule appendaged to the helix and also in the (Fibonacci proportion) 34/21 Angstrom ratio of each complete turn of the helix. Every year, each season has familiar patterns and signs, yet there is a much larger progression we discover when we “zoom out” a bit from our myopic, provincial perspectives. The Chambered Nautilus shell has a pleasing uniformity as one spins the shell around, since each accretion uses the same angular template as the preceding one, and builds upon the strength of sameness throughout.

Here are a few more spirals from our most recent NZ trip; enjoy!

2023 Martineau Solar System Calendars available now

Friday, 23 September 2022 by Bruce Rawles

Once again this perennial calendar is available! These timeless images portray amazingly accurate geometric representations of the planetary orbits in our very own solar system – now available in printed calendar form with dates for 2023!

Martineau Solar System Calendars

These 12 images are highly accurate geometric models of our solar system; details here. They were inspired by the remarkable work of John Martineau (publisher of Wooden Books), who wrote “A Little Book of Coincidence”. Tiled images of planetary surfaces and related images form the backgrounds. Images are two or more orbits defined by simple 2D (circles, triangles, squares, pentagons, hexagons, octagons) or 3D geometries (e.g. tetrahedron, icosahedron, dodecahedron) typically with 99.9% or greater accuracy. The work picks up where Johannes Kepler’s mystical exploration left off. A newly revised calendar (which is updated every year) with images from the Martineau Solar System is again available for 2022.

High Resolution Imaging Science Experiment (HiRISE) camera photos

I suppose one might say that these amazing images are more about geography than geometry, but I imagine that you might also notice that the abstract and seemingly amorphous shapes in these stunning images have some rather interesting geometric attributes, too! Some exhibit fractal patterns one might see flying over USA’s desert southwest and all show the profound intricacies of natural forces sculpting these desolate landscapes. These are all from NASA’s High-Resolution Imaging Science Experiment (HiRISE) camera on the surface of Mars. There are plenty of details on the NASA website that I won’t replicate here.

Of course, if you haven’t already checked out images from the newly celebrated James Web Space Telescope, check out those, too!

Thanks to fellow geometer, Dave Van Dyke – whose art, animation, and music I’ve featured on my personal blog – for alerting me to these artistic images from our cool, neighboring planet.

TurboSquid 3D geometric models

Tuesday, 31 May 2022 by Bruce Rawles

Fellow geometer, 3D animator, techno-nerd, mystic, and life-long friend, Dave Van Dyke alerted me to some examples of very cool 3-dimensional models using TurboSquid (3D Models for Professionals) a couple of days ago. The links below connect with a small set of the many examples of 3-d geometric models – some free, others inexpensive – all gems, especially considering the “labor of love” efforts put into these detailed models! Going beyond geometric constraints, you have orders of magnitude more to explore! They can be downloaded and adapted wherever your imagination might lead! Here are some samples to pique your interest!

SMAs in SMA (SMA-ll stellated dodecahedra in San Miguel de Allende)

Thursday, 5 May 2022 by Bruce Rawles

¡Feliz Cinco de Mayo! Last week, my wife Nancy and I enjoyed a long-overdue, much-needed getaway/vacation and chose San Miguel de Allende, Mexico, a place we’d heard great things about for decades from numerous sources. We very much enjoyed our immersion into the culture, cuisine, and art that this historic city is known for. In addition to world-class dining, lots of “heart decor” and so much more, I was amazed at how many 3D geometric stars were present in this lovely city, both in numerous shops and even in permanent street art! Since artsy stars, wings, and hearts are here in abundance, there are plenty of stellated polyhedra, but the predominant variety seemed to be one of my favorite shapes, the small stellated dodecahedron (one of the four Kepler–Poinsot polyhedra) which I’ve featured in numerous places on this website. I mentioned (in my broken Spanish, resurrected from high school classes a half-century ago) to a few of the shopkeepers that a foldup version that would fit in a tourist’s suitcase might afford more sales, since shipping these lovely fabrications is probably a bit expensive.

If you want to make your own (I suggest trying in cardboard first) here’s a foldup pattern from page 219 of Sacred Geometry Design Sourcebook; you’ll want to make 6 copies of this page. Join the two edges labeled 1 and also join the two edges labeled 2. If you fold together just one copy of this page, you’ll get a double pentagonal pyramid, which is another interesting shape. However, if you fold up the 2 pentagonal pyramid halves, crease the middle shared edge, and fold the other direction, you’ll have 1/6 of what you need to make this classic shape. MC Escher fans will probably recall this classic image.
