We're Back

And you never thought there'd be a second one. Well, I guess you were wrong, huh?

The slogan at the top of this column, the one about "Some things are impossible to know..." comes from the wall of the Infinite corridor at MIT. For a brief period during 1970-71, to cut down graffiti, white paper was placed on the walls of that hallway. That one caught my eye. It was the slogan of this column in its first incarnation, and it brought some luck that time, so it's back.
