In 2005 I attended a colloquium on "Building the Scientific Mind" sponsored by the Learning Development Institute and held at the Institute for Social Studies in The Hague, Netherlands. It was a very interesting meeting of scholars from around the world. Afterward I was able to spend several days enjoying the sites in Amsterdam.
In April 2006 I attended the Fuschl Conversation of the International Federation for Systems Research, held in Fuschl Am See, Austria. In these conversations, small groups of scholars from around the world engage in a dialog on a topic of their choice. It is a far richer experience than most academic or professional conferences.
In summer 2006 I visited friends in Maine, then stopped for some hiking in the White Mountains of New Hampshire.
