Stonehenge and Golden Rectangle

Stonehenge builders had geometry skills to rival Pythagoras. Five years of detailed research, carried out by the Oxford University landscape archaeologist Anthony Johnson, claims that Stonehenge was designed and built using advanced geometry. "The surveyors started by using a rope to create a circle, then laid out the four corners of a square on its circumference, before laying out a second similar square, thus creating an inner octagon..."
