With a Good Ruler All Things are Possible

When I was little, my grandfather was an engineer working at NASA.  He used to give me rulers and templates to play with and I would sit near him as he worked at his drafting table.  I would draw endlessly, creating long elegant lines, perfectly round circles or shapes and marking off radius and diameter before I even knew what they were called.  The paper I worked on was made from the back of his blueprints and often I would turn it over to trace his drafting lines.  I even got to use the good pencils and erasers!  He would continue to give me rulers throughout my school days — wooden T-squares he made himself, sharp metal-edged rulers, wooden fold-out rulers, and for my high school graduation — a slide rule!  Even now I can’t resist the urge to draw lines in repetition to see what happens.  I think this work from this morning has given me a few different ideas, which should work up nicely.
