Adjunct Senior Lecturer
Mr Tim S Roberts
I run Maths Tuition Australia, an organisation devoted to helping kids and adults of all ages and backgrounds, and bringing the joy of mathematics to all. I'm currently looking for tutors across Australia. If you are interested in part-time work as a mathematics tutor, and love mathematics, please contact me!

In 2003 I was fortunate enough to find two previously-unknown magic knight's tours, the first new tours found since 1988, and the first irregular tours found since 1936. The discovery was reported in the April, 2003 issue of Australasian Science. For background theory on the subject, and a comprehensive bibliography, the definitive web site is George Jelliss' History of Magic Knight's Tours.
I'm currently looking at the perfect cuboid problem, and attempting to find such a cuboid with a space diagonal larger than 2,000,000,000,000. The attempt will probably fail, as there may be no such cuboids. However, no-one has as yet managed to find a proof of their non-existence.
