Putting a spin on light: twisting, tangling and topology in waves

The flow of light or other waves is similar to water flowing in a river. Although it tends to travel in a particular direction, it can also flow in whirls and eddies.  Professor Dennis will describe some examples of tangled waves, some application to optical imaging, and how to tie laser beams in knots.
