Description
This geometric model was constructed by Richard P. Baker in the early twentieth century when he was Associate Professor of Mathematics at the University of Iowa. Baker believed that models were essential for the teaching of many parts of mathematics and physics, and over 100 of his models are in the museum collections.
This painted metal and wire structure has a tag that reads: No. 435 (/) Displacement; angle Bisector. It has a wooden base painted black, a painted metal wire extending up for the base, and a metal representation of a bisecting plane between two planes. The metal piece is presently not joined to the supporting wire.
Baker built nine models to correspond to figures described by the German mathematician Eduard Study in a book on the geometry of dynamics (shortened by Baker to Dynamen). This model is one of them, which he described in his 1931 catalog as representing the “Construction of proper angle bisector for two planes which are transforms [sic] by a screw.”
