I remember the good ol'
blackboard as being a soothing influence on me at school - perhaps subconsciously I was thankful there was a tangible presence in the room that could be responsible for, or at least sympathetic to, my vacuous stares. Any academic failings in subjects such as algebra, english or geography (surely not!) were all absorbed by an inky infinite abyss in the same way a black-hole nebula sucks in light. Fast forward to today >> in a digital world of information over-load, and one could be forgiven for assuming that there is now no need for an oldskool blackboard. But if there is still merit in pondering what one does not know (?) (including what one does not know about the
world, the
globe or even
nz), a blackboard conduit, i think, represents a better metaphor for our imperfections and our awe than the ugly false-omniscience of the internet or indeed the sterile blankness of a whiteboard.
