Mathematical Models
The models shown here were ordered from the German company Martin Schilling in the early 1900s by J E A Steggall, the University's first Professor of Mathematics. Most are plaster but some are wire or paper. They represent the three-dimensional appearance of various mathematical equations - some more complex than others!
