This document summarizes a talk about teaching a course on mathematics in art and architecture. It discusses using polyhedral models, frieze and wallpaper patterns, and perspective in paintings to teach mathematical concepts. Specifically, it provides instructions for making paper and plastic models of polyhedra for teaching purposes. It also analyzes symmetry patterns in Ming pottery and discusses the mathematical techniques artists like Vermeer may have used, such as a camera obscura, and challenges in reconstructing their techniques. The talk aims to demonstrate how mathematics appears throughout art and how these topics can be taught to enrich students' lives.
Taipei teaching a course on mathematics in art and architecture
- 1. Teaching a course on Mathematics in Art and Architecture Helmer Aslaksen
- 2. What’s the goal of this talk? • I used to teach two General Education Modules at the National University of Singapore • Heavenly Mathematics & Cultural Astronomy • Mathematics in Art and Architecture
- 3. Content of art course • Tilings and polyhedra • Symmetry • Frieze and wallpaper patterns • Perspective in painting
- 4. Polyhedra • There is a lot of interesting mathematics regarding polyhedra • It is fun to make polyhedral models
- 5. What is the best way to make models?
- 6. There is no best way! • All the methods have advantages and disadvantages. • My goal is to help you make the choice that is right for you.
- 7. Why make polyhedral models?
- 9. They are fun to make!
- 10. They are great for learning!
- 11. They are great for teaching!
- 12. They are great for your department!
- 13. How to make polyhedral models? • Paper • Plastic
- 14. Paper Models
- 15. Platonic and Archimedean solids • Several web pages have nets for the Platonic and Archimedean solids. • Build your own Polyhedra • Paper Models of Polyhedra • douglas zongker polyhedra models.
- 17. Plastic Model Kits • Zome Tool • Polydron • Jovo
- 18. Zome Tool
- 19. Polydron
- 21. Jovo
- 22. Face or edge? Polydron/Frameworks and Jovo are face based Zome is edge based
- 23. Advantages of Polydron and Jovo • Easier to assemble. • Green struts in Zome require some practice. • Makes more sense for non-convex models. • Colored faces. • Models are smaller, especially with Jovo. • Tilings.
- 24. Advantages of Zome • Unlimited possibilities. • Nested models.
- 25. Zome possibilities • Zome Geometry: Hands on Learning With Zome Models by George W. Hart and Henri Picciotto. • Soap bubbles.
- 26. Which Platonic/Archimedean solids can you make? • Zome: All except the snub cube and snub dodecahedron. The struts can only be pointed in certain directions. • Polydron: All except the truncated dodecahedron and the great rhombicosidodecahedron. No decagon. • Jovo: The basic set only contain triangle, square and pentagon. Hexagon in an additional package.
- 27. Jovo models • Basic Jovo can only make six of the 13 Archimedean solids. With hexagons we can make three more. But truncated cube and great rhombicuboctahedron require octagons.
- 28. What are your needs? • Do you need to quickly make some models for demonstration purposes or simple student activities? • Do you or the students want to explore further? • Do you have a large class or a small group? • What is your budget?

- 54. Perspective in painting • Perspective in painting and photographs has many applications to the world around us
- 55. Giotto, The Flight into Egypt, c1313 • Notice how the trees are the same size
- 56. Lorenzetti, The Presentation in the Temple, c1342 • Notice how the tiles get smaller
- 57. Masaccio, Trinity, 1427 • One of the first perspective pictures
- 58. Side Vanishing Points • One of the basic results in inverse projective geometry is that the distance between the central vanishing point and side vanishing point of a square is equal to the distance between the observer (camera) and the picture plane
- 59. Side Vanishing Points 2
- 60. Where’s the best view point? • 174cm above, 770cm away
- 61. False viewpoints • Pozzo’s ceiling (1694) and cupola (1685) in St. Ignazio, Rome

- 64. What does a sphere look like?
- 65. What’s going on here?
- 66. Vermeer (1632—1675) The Music Lesson (1662-5) Royal Collection, London
- 67. Did Vermeer use Optical Aids? • This was suggested already in 1891 by the photographer Joseph Pennell • Some of his paintings “look like photographs”, including sections that seem to be out of focus or use counterintuitive perspective
- 68. Counterintuitive Perspective Compare The Procuress by van Honthorst and Officer and Laughing Girl by Vermeer Many art historians accept that Vermeer used a camera obscura (pinhole camera)
- 69. Girl with a Pearl Earring • He is seen using a camera obscura in the movie Girl with a Pearl Earring
- 70. Vermeer’s Studio • Several of his paintings appear to have been painted in the same studio • We see similar windows on the left wall, wooden joists in the ceiling and tiles on the floor
- 71. Lady Standing at the Virginals (1670-3), National Gallery, London
- 72. Steadman’s Reconstruction • Philip Steadman did a 1/6 scale model reconstruction of The Music Lesson in a BBC TV program in 1989
- 73. Vermeer’s Camera • More details are given in his book Vermeer’s Camera (2001)
- 74. What is Special about The Music Lesson?
- 75. Inverse Projective Geometry • Several people have studied the problem of reconstructing 3D information from 2D images • Criminisi: Accurate Visual Metrology from Single and Multiple Uncalibrated Images • Byers, Henle: Where the Camera Was, Mathematics Magazine • Crannell: Where the Camera Was, Take Two, Mathematics Magazine
- 76. Student Work • Inverse projective geometry is suitable for student work at many different levels • From simple measurements and computation to literature surveys and software implementation • Unfortunately, serious applications require serious applied math/engineering skills
- 77. The Mystery of the Mirror • The mirror is central to all mathematical analysis of this paper, but instead of solving our problems, it reveals a slew of questions • Why would anybody hang a mirror there? • Is it for the lady to look at herself, or for us to look at her? • Is it for the artist to give us a glimpse into his secrets?
- 78. The Angel and the Shadow • In Steadman’s reconstruction, almost everything looks perfect, except for the angle of the mirror and its shadow on the wall • He had to increase the angle of the mirror to make us see the lady in the mirror • He could not make the lady and her mirror image line up • What did Vermeer do?
- 79. Future work • Gothic architecture • Salsa dance
- 80. Gothic vaults
- 81. More vaults
- 82. Mathematics of Salsa dancing • How to remember dance moves • Leg work is easy, arm work is hard • Construct a language to describe moves
- 83. Some contrarian thoughts • Can I convince my department chair and dean that this is math? • Can I convince the director of an art museum that this is art? • Can I convince your students that this class will enrich their life?
- 84. What is Mathematics and Art? • I sometimes find it useful to think of the following four categories • Mathematics in art • Mathematical art • Mathematics as art • Mathematics is art
- 85. Mathematics in Art • Topics like perspective in painting, symmetry in ornamental art and musical scales. • Material that even the most anti-scientific art connoisseur will appreciate. • You can approach any art museum with an offer of a public lecture on such topics.
- 86. Mathematical Art • Escher and other mathematically inclined artists. • Worshiped by mathematicians, frowned upon or ignored by the art community. • Strict “no Escher” policy at the Singapore Art Museum. • An offer to an art museum of a public lecture about Escher may not necessarily be accepted.
- 87. Mathematics as Art • Computers allow us to create beautiful visual mathematics. • How many art museums would be interested in a public lecture about the Mandelbrot set?
- 88. Mathematics is Art • Many mathematicians believe that mathematics is an art, not a science. • No art museum would be interested in a public lecture on Euclid’s axioms.
- 89. Have fun designing your own course! • Good luck and thank you!
