Arnold Tubis received B.S. and Ph.D. degrees in physics from MIT. He was a member of the faculty of Purdue University from 1960 to 2000 (including nine years as a department head) and is the author or co-author of over a hundred research papers. He now lives in Carlsbad, California, where he is a visiting fellow at the University of California, San Diego in La Jolla and a consultant in the areas of auditory biophysics and the use of origami in K-12 mathematics education. He is currently working on a pilot origami-mathematics project in the Long Beach, California, school district. As an origami enthusiast since the early 1960s, Arnold has given many origami presentations and workshops focused on both the arts and mathematics, and has had his models on display in exhibitions in the United States, Europe, and Japan. His other interests include travel, playing the piano, and collecting and playing "strange" musical instruments.
