Mathematics: Some assembly needed
Ian Stewart1
Abstract
Origami, the ancient Japanese art of paper folding, is mathematically deeper than it looks. Delving into its complexities allows the construction of elaborate and useful structures from simple, flat templates.
Saving space is an imperative in commerce, engineering and the structure of living creatures. Furniture and garden equipment come in flat-packs to save storage space in the warehouse and the delivery van — and, it must be said, to make the purchaser do all that time-consuming work of assembly.
- Ian Stewart is at the Warwick Mathematics Institute, Zeeman Building, University of Warwick, Coventry CV4 7AL, UK.
