text: a perimeter of a circle can be found from 2 phi and radius. phi=22/7 or 3.14..from where does this point come?   in 1537, copernicus decided that by finding pi, (22/7 or 3.14) you could find the perimeter of a circle by simply using his formula 2*3.14=r*r ... therefore creating the theory of numeric revolution.  davinci understood this and then created the "code" and by that time, dan brown published his book and the catholics lost their damn mind by allowing their priests to molest young boys.  hope that answered your question young lady.
