The topic of questioning fundamental assumptions is taken to a level deeper with the example of Euclidâs fifth postulate and hyperbolic geometry, illustrated with [https://mathstat.slu.edu/escher/index.php/Circle_Limit_Exploration M.C. Escherâs Circle limit I]. The notion that all the black and white fish near the boundary are equal in âsizeâ to the fish near the center starts the section with an interesting point of confusion between our visual perception of Euclidean geometry and the hyperbolic representation. | The topic of questioning fundamental assumptions is taken to a level deeper with the example of Euclidâs fifth postulate and hyperbolic geometry, illustrated with [https://mathstat.slu.edu/escher/index.php/Circle_Limit_Exploration M.C.
