I had a very interesting and wonderful day today. It began with a pleasant breakfast and stroll about Cambridge with Andrew Grumet and Dave Winer. We spoke of many things, of shoes and ships and sealing wax, of cabbages and kings. I next spent several hours walking around "Harvard Yard"; the Harvard campus itself, and the delightful area which surrounds it. Among other things, it is great for shopping, and people watching, and thinking. I then met up with my friend and colleague Ul Balis, his wife Jennifer, and sons John and Hyke, and the five of us toured the fabulous Boston Museum of Science, finishing up with dinner at an Afghan restaurant. Terrific.
