Solar System Geometry (per Martineau) Wall Calendars for 2027

Friday, 28 August 2026 by Bruce Rawles

This perennial wall calendar is now available for 2027! It has a dozen high-resolution planetary art images representing very accurate models of geometric relationships between planetary orbits in our solar system. This timeless monthly calendar now has 2027 dates.

Martineau Solar System Calendars

Martineau solar system calendar -12 months

These 12 images are highly accurate geometric models of our solar system; details are 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.

Encyclopedia of Polyhedra By George W. Hart … and other geometric gems

Sunday, 16 March 2025 by Bruce Rawles

Apples and Oranges by George W. Hart https://www.georgehart.com/Applorng.html
Apples and Oranges by George W. Hart

It’s time to revisit the work of other polyhedra enthusiasts. Of particular note (having crossed my digital path again recently) is George W. Hart who has shared some excellent resources along these lines (faces, vertices, etc.) for decades. Here’s one gold mine to explore: Virtual Polyhedra: The Encyclopedia of Polyhedra By George W. Hart. Here is part of the table of contents and highly recommended if you want to explore the genres and categories of polyhedra; lots of great imagery, rotatable 3D models (rotate them with your mouse), facts and details:

  • Platonic Solids (Regular Convex Polyhedra) Background List of models
  • Kepler-Poinsot Polyhedra (Regular NonConvex Polyhedra)Background List of models
  • Archimedean Polyhedra (Semi-Regular Convex Polyhedra) Background List of models
  • Prisms and Anti-Prisms Background List of models
  • Archimedean Duals Background List of models
  • Quasi-Regular Polyhedra Background List of Models
  • Johnson Solids (the remaining convex polyhedra with regular faces) Background List of models
  • Pyramids, Dipyramids, and Trapezohedra Background List of models
  • Compound Polyhedra — Introduction Background List of models
  • Stellated Polyhedra — Introduction Background List of models
  • Compounds of Cubes Background List of models
  • Convex Deltahedra Background List of models
  • Zonohedra Background List of models
  • Uniform Polyhedra Background List of models
  • Uniform Compounds of Uniform Polyhedra Background List of models
  • Stellations of the Icosahedron Background List of models
  • Stellations of the Rhombic Triacontahedron Background List of models

Perhaps the most well-known and ubiquitous polyhedral shapes have fold-up models (and related patterns) for the first 3 categories above in Sacred Geometry Design Sourcebook (SGDS pages 196-220) and also on this website for the 5 Platonic Solids and 13 Archimedean Solids as well as Illustrations of Platonic And Archimedean Solids, Math Tables for Platonic And Archimedean Solids (and much more about polyhedra on this website.

If you exhaust this generous resource (or somehow overlook a few gems) here are more of his contributions – the videos are particularly helpful if you want to replicate his constructions:

  • The Pavilion of Polyhedreality
  • George’s Instagram page with some excellent 3D geometric sculptures
  • Mathematical Impressions: The Golden Ratio (short video)
  • Hyperboloids (short video)
  • Little Zonohedral Library (short video; my favorite of these which also features our mutual friend Russell Towle who showed me his 3D zonohedral models (such as Rhombic Spirallohedra)
    years ago in Dutch Flat, California)
  • Ceci n’est pas une lampe (fun, clever, short video)
  • Birdland (another clever short video)
  • Seven Slide-Together Constructions (another interesting short video)
  • … and MANY more!
