David Wees @davidwees.bsky.social · 12/05/2025Asking the UK mathematicians on BlueSky. What is your definition of a face? In North America, we use this definition in English: "a face is a flat surface (a planar region) that forms part of the boundary of a solid object." So for a cylinder, the two ends of the cylinder are faces. #ukmath #maths 120
