The centrepiece of McAllister building, which houses the math department at Penn State, is the Octacube, designed by Adrian Ocneanu.

alt text

There's a bit of a description of the mathematics behind the Octacube on the Penn State website, but unfortunately, that's the most material that I can find online. There are all kinds of animations set up to display on a computer terminal in McAllister building, but they don't seem to be available online anymore.

Very briefly, the mathematics of the sculpture is as follows: consider the four-dimensional regular convex polytope whose vertex set is the union of the vertex sets for the four-dimensional cube {(±1,±1,±1,±1)} and the four-dimensional octahedron {(±2,0,0,0), (0,±2,0,0), (0,0,±2,0), (0,0,0,±2)}. Consider the 1-skeleton of this polytope (vertices and edges), and project radially to S3 ⊂ ℝ4. Project the resulting "inflated polytope" stereographically to ℝ3, and "fatten" the edges so that a cross-section of an edge is no longer just a point, but a Y-shape (see the corners of the sculpture). What you get is the sculpture shown.

Permutahedron sundial

3-D Permutahedron Sundial by Stefano Buonsignori (16th century) in the Medici collection presented by Museo Galileo. The 3-D permutahedron:

(The combinatorics underlying the geometry of the permutahedra are related to multiplicative inversion and, consequently, to Koszul duality and the formalism of Appell sequences and associated matrices, so I find this particular jewel at the juncture of art, engineering, geometry, combinatorics, and analysis particularly exciting. If only he had done one for the associahedron!)

Eversion of a sphere: Models in resin made by Stewart Dickson of clay models made by Bernard Morin (a blind topologist!) of different stages of the eversion of a sphere. The resin models were presented at the Maubeuge symposium "Arts et Mathématiques." (Photo by John Sullivan.)

Excerpt (p. 146) from "Poincare's Prize" by G Szipiro:

(Smale) proved a theorem that showed it is possible to evert the sphere. But the procedure implicit in his theorem was so complicated that nobody could visualize it. Smale, and others who tried, wanted to see with their own eyes how the sphere would evert. For once, the ability to visualize may actually have been a handicap. It was left to the blind mathematician Bernard Morin to devise a procedure to turn a sphere inside out that could actually be implemented (if the membrane is able to pass through itself, that is.)

Isometric transformation between a catenoid and helicoid

Presented at the 2019 Mathematical Art Exhibition held at the AMS Joint Mathematical Meetings in Baltimore, MD. (30 x 25 x 25 cm, paper, mdf, steel, magnet, 2018.)

To the left is a paper-crafted catenoid, and to the right, a helicoid. These surfaces can be transformed isometrically into each other, i.e., without any strain, because the first fundamental form of the surfaces are identical.

I made this model by weaving together paper strips whose shapes were obtained by minimizing the strain energy defined on a Riemannian manifold. The optimization problem was solved numerically using NURBS-based isogeometric analysis.

Gates to the Center for Mathematical Studies at Cambridge

From "What is ... a Skein Module" by Lickorish:

Mathematical Gates. The main entrance to the Centre for Mathematical Sciences in Cambridge is sealed by iron gates. Medallions in these gates show the only two knots with at most eleven crossings, other than the unknot, that have trivial Alexander polynomial. One gate shows the knot studied by S. Kinoshita and H. Terasaka, whilst the other gate shows the knot discovered by J. H. Conway in his classification of eleven-crossing knots. Related as they are by one of Conway’s mutations they cannot be distinguished by any invariant based on skein theory. The medallions were created by John Robinson and donated by Damon de Laszlo and Robert Hefner III.

Dodecahedron

Dodecahedron at Burning Man

From Satayan L. Devadoss:

UNFOLDING HUMANITY: BURNING MAN (2018)

A two-ton metal, wood, and acrylic interactive sculpture, showcasing unsolved problems of mathematics, came to life in the middle of the Nevada desert. Rising 12 feet tall with an 18-foot wingspan, the unfolding dodecahedron was externally skinned with black panels containing 2240 acrylic windows, illuminated by over 16,000 LEDs which were programmed and driven by 20 controllers. The interior, large enough to hold 15 people, was fully lined with a massive mirror over each of the twelve pentagonal faces.

Our motivating question asks, what could it look like for vibrant and unsolved mathematics to be made embodied and physical, to engage the general public? And so, this sculpture deals with two unsolved questions: the unknown possibility of unfolding any convex polyhedra (motivated by 500-year-old works of Albrecht Dürer) and the shape of our universe (from WMAP cosmic microwave background radiation data and the Poincaré dodecahedral space). enter image description here

See See Figs. 3.14 on pg. 76 and 7.28 on pg. 241 of Discrete and Computational Geometry by Devadoss and O'Rourke. "The vertices of this polytope correspond to all ways of triangulating the regular seven-gon, and the edges connect two such triangulations related by a flip."--Devadoss at link above.

A Seifert Surface Bordered by Borromean Rings

The sculptures of Morton C Bradley are not so widely known. He was originally an art conservator in Boston, but he also explored geometric shapes and color to create many sculptures. They are "a reflection of his fascination with the science of color, his admiration for traditional patterns, his exploration of mathematical designs." (Quote from web site below.) He never sold a single piece of work. At his death he donated his entire estate to Indiana University. The IU Art Museum is cataloging his work and arranging exhibits. They've created a web site http://www.iub.edu/~iuam/online_modules/bradley/ that discusses and displays some of his work. In comparison with other work already mentioned here, perhaps the most significant thing is his deep exploration of color in his sculptures.

This sculpture is made of 30 interlocking pieces and requires many hands to assemble or disassemble.

This sprinkler illustrates a theorem that a 3d solid can be constructed to cast any desired set of silhouettes (also illustrated on the cover of Gödel, Escher, Bach).

The gömböc—as, for example, in this image—is a homogeneous convex solid with one stable, one unstable, and no neutral point of equilibrium on a horizontal plane. Its existence was conjectured by Vladimir Arnol'd in 1995 proved in 2006 by Gábor Domokos and Péter Várkonyi. Its manufacture requires great precision, and true gömböcs are not hand-made by individual artists.

$\endgroup$

  • $\begingroup$ (Just checking: did you intend to write that true gömböcök are not hand-made by artists? It kind-of makes sense, though the opposite statement would also make sense, so this could be an oversight. I shy away from changing this, of course, and will only correct the spelling.) $\endgroup$ Mar 5, 2018 at 8:34

    $\begingroup$ @PeterHeinig: (1) In English, it is normal to anglicize the spelling, pronunciation, and grammatical declension of foreign words. My preferred spellings of gomboc and its plural form gombocs were both edited to gömböc; but in your comment the plural is distinguished as gömböcök. (2) The manufacturing tolerance is one part per thousand over a convex shape defined by complicated mathematical formulas. So the gomboc is well suited to computer-guided machining and would be very difficult, if possible at all, for a human sculptor to make. $\endgroup$ Mar 5, 2018 at 10:12
  • $\begingroup$ Thanks. I am sorry, the missing 's' after the second 'gömböc' was simply my mistake. I'll correct it. The umlaut seems very usual even in the English literature on the subject, though, so I'll keep the umlaut. Thanks for clarifying that gömböcök are usually not manufactured by individuals. $\endgroup$ Mar 5, 2018 at 10:39
