Knowledge of the World- World of Knowledge - Mathematical models and artistic mapping: Installation - Ballyhaunis , Co. Mayo , Ireland

Maps and data visualisation are frequent obsessions of Ralf Sander, and the intersection of both.

Pioneers across cartography, information design, and other disciplines that have historically shaped our understanding of space and spatial relations, alongside bleeding-edge projects across data visualization
From the ancient maps of Ptolemy to the seminal work of information design pioneer Edward Tufte, cognitive mapping pioneer Kevin Lynch, and Riemann`s mapping theorem https://en.wikipedia.org/wiki/Riemann_mapping_theorem, Sander searches for techniques, appropriate for the interconnected, dimensional complexity of maps as living organisms in an artistic form.
Sander evaluated forms of map projections from the mercator projection, Peters projection, Mollweide projection to the Pointcare conjecture for his project.
Conversations with Prof Jorge Kohanoff, School of Mathematics and Physics, Queens University inspired the idea for the shape of the globe derived from a mathematical Riemann (Georg Friedrich Bernard Rieman 1826-1866) Figure.
A Riemann surface is a type of mathematical object that is used to represent the complex structure of a function with multiple valued outputs. It is a two-dimensional surface that is locally similar to the complex plane, but which may have a more complicated global structure due to the presence of branch points or other singularities.

Sander started this research in the context of his John Steward Bell memorial (Football and Physics, 2018) where he developed an infinite football pitch based on a mobius figure. A public art project at Ballyhaunis school in Ireland, Co. Mayo enabled him to make a large-scale objects based on his sculptural models.
