Geometric Dissections Now Swing and Twist
Purdue University Annual Weekend class (School of Science)
Instructor: Greg N. Frederickson,
Professor of Computer Science
A geometric dissection is a cutting of one geometric figure into pieces
that can be rearranged to form another figure. Some dissections can be
connected with hinges so that the pieces form one figure when swung one
way, and like magic, form the other figure when swung another way.
This course will explore ways to design hinged dissections,
emphasizing their underlying patterns, symmetry, and beauty.
The instructor, who is the author of the recent book
Hinged Dissections: Swinging & Twisting,
will also present dissections whose pieces twist from one figure to another.
