The Shape of Space

Associate Professor John Stillwell


Mathematics knows many different spaces, but which is the space we live in? Is it finite or infinite? And if it is finite, how might we tell? This talk is an introduction to the possible forms of 3-dimensional space and what they look like from the inside. In particular, we will look at 3-dimensional spaces analogous to the 2-dimensional surfaces of the sphere, cylinder and torus, and some other, weirder, possibilities. Those who have seen the book "The Shape of Space" by Jeff Weeks will notice some overlap with this talk, but not too much.
