Students, faculty, staff, and other interested parties are invited to the science and destruction of the Menger Sponge currently on display in Cole Library. The Menger Sponge—a three-dimensional fractal formed by successively removing the middles of cubes—is constructed out of pieces of paper the size of business cards, with over 65,000 individual pieces of paper. Built in May 2006 by members of the Math Club, the Menger Sponge is now showing signs of old age. As the sponge is too large to fit through the doors of Cole Library, and repair would involve essentially rebuilding it from the ground up, the sponge has graciously willed its body to science and charity. The department of physics will demonstrate how to measure the moment of inertia of the Menger Sponge on Friday, Nov. 6, at 3:30 p.m. in Cole Library. At the completion of the science, anyone interested in taking a wack at the spinning sponge may do so by making a contribution to Cole Library. Contact Jim Freeman with questions.
