Even on its laziest days, the figure-eight knot keeps climbers from falling and a boat's sails in place better than the measly trefoil overhand knot (totally inferior knot). Does the figure-eight save lives? Many would say so. We will discuss the topology and geometry of this life-saving knot, which is the unique 4-crossing and the simplest hyperbolic knot. Our friend the figure-eight knot will guide us as we introduce some important classical concepts and techniques in the fields of knot theory and low-dimensional topology. This is a BYOR (Bring Your Own Rope) event due to COVID-19.
