Abstract: In principle, the surface of a donut--called a torus--can be obtained by gluing the opposite edges of a rectangle to each other. So, what about in practice? Is it possible to literally bend/fold/roll a flat piece of paper and tape the opposite edges together? What about other surfaces? We'll explore these questions and illustrate with 3D models some of the mathematical concepts that underlie them.
