The Fifth Axiom of Geometry

For centuries Eucledian Geometry was the only known geometry. It was based on 5 basic assumptions called axioms. From these and the rules of logic mathematicians derived all the theorems of geometry, and built a complete model of the world. In the 18th Century, curious mathematicians began to question the Fifth Axiom. The results were two new types of geometry called Hyperbolic Geometry and Elliptic  Geometry, which yielded great new ways to understand the world. Our name pays homage to a great principle of understanding: To Challenge Assumptions. We believe that the great developments in our social life, in culture, literature, science, mathematics and business have been ignited by a challenge to an assumption. This is our approach to business, we look at problems in new ways, by building new systems using different axioms.
