One fine day I was going about my business when I heard that the Maths Tower at Manchester University was to be demolished. I was shocked. To me it was an inspirational icon of learning, the thing that put the campus on the skyline, on the map, and on the picture postcards. I used to sit on the seventeenth floor in a class, learning about gates and induction from the likes of Tom Kilburn, godfather of Computer Science. I listened intently with the cityscape before me and Jodrell Bank behind. I learned a lot in that Maths Tower. It shaped my life, it was my beacon. And now it’s gone.
