Leonardo da Vinci said, “Man is the model of the world.” The Vitruvian Man by da Vinci is a study of the proportions present in the human body. The Golden Ratio or Divine Proportion is ubiquitous throughout the Vitruvian Man.
The Golden Ratio (also known as the Golden Mean and the Divine Ratio), in my opinion is more significant that the otherwise known Most Important Number — Pi.
Fibonacci de Pisa was the most influential 12th century western mathematician. His father was an important Italian merchant or trader of goods. On a trip to Egypt around 1200AD, Fibonacci was introduced to Arabic numerals (0,1,2,3,4,5,6,7,8,9….) formerly unknown to Europe where the system of numbers were Roman (I,II,III,IV,V,VI,VII,VIII,IX,X…..).
After exploring the relative sizes of the planets in our solar system last week, we explored another key geographical misconception. The current map of the seven continents on planet Earth was created by an Euro-centric Flemish cartographer named Gerardus Mercator in 1569.
Mathematicians and all persons of reason are taught to question everything. And yet, from the time I was a child fascinated with the stars and planets in our solar system, I assumed that the pictures in all of the books were accurate. That couldn’t have been further from the truth. Not a single picture I every saw had a disclaimer that said, “not drawn to scale.”
