Intelligent'Er Re'Development is an international think tank that uses digital intelligence to rethink global development challenges with a decentralised citizen-centric perspective.
Our approach to challenges is systemic and holistic and, in an attempt to square the development circle, we run The Collaboratory, a community of experts to promote intelligent and proportional development.

The Vitruvian Man (Le Proporzioni del Corpo Humano secondo Vitruvio) is a drawing by the architect Leonardo Da Vinci from 1490 in which he uses the description of human proportions made by Vitruvio in his architectural treaty (De Architectura, Book III, 15 BC) to draw his own body. Leonardo uses the Divine Proportion (or Golden Ratio) to fit his body in a circle and a square at the same time.. However, geometrical studies prove that the different body parts of Leonardo's Vitruvian Man only aproximate the Golden Ratio, but totally correspond with Vitruvio's modulor, which divides Golden Ratio into parts to make it more usable as a standard for architecture and urban planning.

Using only a compass and a straightedge it is geometrically impossible to draw a square that has the same area as its closest circle. This mathematical problem was solved by the ancient geometricians by using the Divine Proportion or Golden Ratio, which is mathematically expressed by the Φ (phi) number. The circle can be squared if its radius is elevated to the second power and multiplied by Φ. The area of this circle will equal the area of a square, base per height, The height of the Vitruvian man is the height of the square and the distance between his navel and the bottom is the radius of the circle.

At Intelligent'Er we work to find intelligent proportions for global development the same way the ancient geometricians worked to find the φ number to square the circle
