I am putting together material for a discussion of Tom Friedman’s "flatteners", including the fall of the Berlin wall, and found this excellent personal account, by Andreas Ramos, of what happened. I didn’t get to see this myself, but my parents went to Berlin for New Year’s 1989 and told stories of thousands of people – some in suit and tie – chipping down the wall by hand. And I remember a German systems developer we had working for us, who sat all day by the radio with tears streaming down his cheeks.

What a day, what a moment.
