Bobby finished his galaxy poster today. And a fine job it was. He still had the labels of the various portrayed objects to glue onto the poster, and as I laid them out on the table (he had prepared them in our last class) Bobby remembered so well which object was which. This was not a requirement, for I'm more concerned with the underlying science, but it was amazing to see what an excellent memory Bobby has with respect to these astronomical objects (he also remembered the names of the nebulae when we worked on his previous project).
