This is something I've been wondering about since a long time. Although we can
make a circle as precise as we want, I think we cannot make a really
precise straight line - every straight line is made from another one or from a tool
that has been made using some older straight lines - so it all comes down to
copying a line that has been made thousands years ago. Although we have precise
instruments and tools, we can only make better and better lines (so that eventually
the error is less than an atom, and we are there), but IMHO there is no
process to create a straight line directly. Or is it?
