Sažetak
In this article we will construct plastic number in a heuristic way, explaining its relation to human perception in three-dimensional space through architectural style of Dom Hans van der Laan. Furthermore, it will be shown that the plastic number and the golden ratio special cases of more general definition. Finally, we will explain how van der Laan’s discovery relates to perception in pitch space, how to define and tune Padovan intervals and, subsequently, how to construct chromatic scale temperament using the plastic number.
