Mathematical Art & Play
The MLC believes that students and staff should not just learn and use maths, but also enjoy it. So we engage in a lot of mathematical art and play.
To find out more about any of these activities, please contact us.
One Hundred Factorial is a gathering of staff, students and friends to solve puzzles and play mathematical games together, both online and face-to-face. We have face-to-face games and puzzle sessions on campus regularly during teaching weeks, and monthly at other times. You can also follow our puzzle-solving on social media.

MLC lecturer David occasionally blogs about the puzzles we do at One Hundred Factorial on his blog. Check out these posts at the link below:
You can join in with the conversation on Twitter by using the hashtag #100factorial.
MLC Lecturer David Butler creates mathematical artworks, usually of a collaborative constructive nature. See photos of past artwork here, and find out more about each below.
This artwork is being constructed across 2016 and 2017, and features the 3D shape called a "silver rhombic dodecahedron". They are built from an origami unit folded from A4 paper. To find out more, follow the link to the Space-Filling/Mind-Filling page.
My Piece of Pi
This is a collaborative artwork designed by David K Butler (one of the MLC lecturers). We plan to draw more than 1000 digits of the number pi on the North Terrace campus of the University of Adelaide Adelaide on International Pi Approximation Day 22nd of July. To find out more, follow the link to the My Piece of Pi page.
Used AdelaideMetro public transport tickets were be glued together according to simple rules to construct a random cellular automaton, creating tree-like patterns as more tickets are added. To find out more, follow the link to the Random Journeys Page
The Sierpinski Sponge
Several thousand paper pyramids were made and stuck together to build a model of a 3D fractal known as the Sieprinski Sponge, in 2011 and in 2015. To find out more, follow the link to the Sierpinski Sponge Page
The MLC lecturers like to create and collect puzzles and games. Here are some that you might find interesting:
- 16 Sudokus -- a set of 16 sudoku puzzles with a connection
- Quarter the Cross -- an open-ended puzzle with a creative flair (also check out the Twitter hashtag #QuarterTheCross)
- 4-Dimensional Noughts and Crosses -- a two-player game that requires spatial thinking in four dimensions
- Which Number Where -- a two-player game that is a bit like battleships and a bit like Guess Who.
Occasionally, the MLC lecturers give seminars on maths or maths-related topics, where the focus is on the fun or interest of the maths. Find out more about the past seminars here.
Secrets of Alice in Wonderland
This live streaming show was presented by David Butler and Cobi Smith at the Royal Institution of Australia as part of Science Week 2012 and the Great Big Science Read project. To find out more about the show, check out the page on the RiAus website

⌊ n!/e ⌉
This seminar will be given by David Butler as part of the School of Mathematical Sciences Undergraduate Seminar Series in September 2014.
Date: Tue 9 Sep 2014
Time: 2:10 pm
Place: Inkgarni Wardli 715 Conference Room
What is this formula? Why does it use those strangely mismatched brackets, and why does it use both factorial and the number e? What is it supposed to calculate? And why would someone love it so much that they put it on a t-shirt? In this seminar you will find out the answers to all of these questions, and also find out what derangements have to do with Taylor's theorem.

Eigenvalue Magic Tricks
This seminar was given by David Butler as part of the School of Mathematical Sciences Undergraduate Seminar Series in August 2013.
Eigenvalues are awesome, but students rarely get the chance to see just how supremely awesome they are. In this talk I’ll tell you some awesome truths about eigenvalues that you don’t get to see in first year, and show you their proofs, which happen to contain some of the most clever magic tricks in the whole of maths.
