About

Some mathematics of straight lines. Why are electricity pylons made of triangular patterns of struts? Rigid shapes and flexible shapes. What is the smallest number of attendants you need to watch all the paintings on the wall of an art gallery of any shape with straight walls, and any number of rooms? What if the attendants move around? What is the smallest number of cameras you need to watch the outside walls of a prison? What is the smallest number of spotlights needed to illuminate a stage of any size?
