The prolific Greek mathematician and geographer Eratosthenes came to understand that the world wasn’t flat when he calculated the circumference of the earth in the third century BC. Portuguese explorer, Ferdinand Magellan – 1,800 years later - again reminded us that the earth was not flat when his fleet successfully circumnavigated the globe in 1522 AD. Awareness that the earth is not flat has existed for centuries, yet we continue to constrain our engineering design efforts to two dimensions.
