How do you know that the line you draw is really straight? What defines straightness? If you look down the line and you don't see wobbling, is it straight? Can you transfer that line to a piece of metal, cut it out and use that metal as a straightedge for drawings? More fundamentally, how do we come to trust our empirical work? When a really complicated gadget like a particle accelerator is running, how much error is there? Henry Choy choy@cs.usask.ca
