Steven Johnson was the guest on KUOW Weekday today. Ironically I found his TED video last week. I absolutely love his ideas, and believe that new ideas emerge only in interaction and relationship with other concepts and ideas. When I taught my FIG at the UW for CHID 110. I used to open all the windows and encourage the students to wander off in thought and look out the window during class. The idea being that the more outside stimulus, the more new ideas will form.
