Harry and Rafe continue the discussion around coming to understand the nature of light.  In this episode they discuss the properties of waves (interferences and such) and how the nature of light is like the nature of sound except for the fact that light waves seem to be able to travel without any medium to support them.  In the end, our friend Albert Michelson will again show up to finally put the ether to rest setting the stage another Albert to come to the front with Special Relativity.

In true Buf fashion, the conversation drifts to things like the teaching of mathematics in high schools and to donuts; the more things change, the more they stay the same.
