№ 220/2012 from Aug 10, 2012
Mathematics students from Freie Universität Berlin are building a model of five nested cubes, the largest ever such model built in Germany. The complex geometric object "Five Cubes without Corners" will consist of 22,000 individual parts, will be three feet tall, and can be walked on. The model is being built in the toy department of a downtown department store, KaDeWe, where it will be on display until August 27.
In their public "geometry lesson" the students will be using the construction toy Zometool. Employees of the company will be on hand to offer support. Zometool is suitable for the construction of large models such as Platonic solids or hypercubes in the fourth dimension.
Math students from Freie Universität undertook a similar project in July 2011, when they put together the largest model of a Platonic solid in four-dimensional space. It had 20,000 components.
