somEthiNg to thiNk aBoUt another item from Mathematical Recreation and Essays… the Könisberg bridge Problem An elemental plan of Könisberg is given below. It shows an island in the river Pregel. The river has two branches as shown. There are seven bridges in all. The problem is to define a walk such that it crosses every bridge once and only once, and returns to its start point. Clearly, this is not possible. However, it could be possible if one or more additional bridges were built. Where would this (or they) be built?

Photos From thE BraNch agm aNd diNNEr FEBrUary 26, 2011

The curious photo featured in NB160 is that of the Irvine Road Burner (also known as the Irvine Travelling Furnace). This is a great example of an Australian innovation. Production began in 1927 and only two were made. These machines literally burnt black soil to create a ceramic surface about five inches thick and was used for road-making in the Eastern Darling Downs. The machine in the photo was transported by ship to Brisbane in 1932 and did trials between Grantham and Gatton before being moved into the Darling Downs. It finished work before World War II and was never fired up again. It lay silent in the one location for 63 years until it was moved to the Jondaryan Woolshed in May 1999.
