When I photographed these rulers up close, I realised how different the 'Ocm' measurement mark is. I came to the conclusion that zero can't be described in the measurement of cm, 'nothing' cannot be measured. But if nothing is something... zero, then there must be some kind of measurement for it? For our crit I put up these pictures of blown-up rulers to show the difference in the zero line..
I need to work out how I'm going to properly visualise what I've found out and what to do with it now!
