When many of us view a great building, we are struck by the majesty and artistry that spring from its form, function and materials. University of Notre Dame mathematician Alexander J. Hahn sees all this, but also something more. He sees the mathematics that lies at the heart of great buildings and finds in it a beauty of its own.

Hahn examines the mathematics at work in great buildings in a compelling and richly illustrated new book "Mathematical Excursions to the World's Greatest Buildings," published by Princeton University Press.

"The Mathematical Excursions" discuss the pyramids of Egypt, the Parthenon in Athens, the Colosseum and Pantheon in Rome, the Hagia Sophia, historic mosques, great Romanesque, Gothic and Renaissance cathedrals, some of Palladio's villas, the US Capitol, and three icons of the 20th century: the Sydney Opera House, Gateway Arch in St. Louis and the Guggenheim Museum in Bilbao.

"The mathematics provides insights that verbal descriptions or even sets if images cannot convey."

The idea for the book grew out of Hahn's longstanding interest in architecture, especially European architecture, and the many informative conversations he had had over the years with his friends and colleagues in Notre Dame's School of Architecture.

"The book intertwines two stories, one architectural, one mathematical, into an interlaced fabric," Hahn said. "On the one hand, mathematics enhances the understanding of architecture; on the other, the architecture is an attractive stage that makes basic abstract mathematics visible.

"It is not the aim of this narrative to provide a comprehensive study of these famous structures but only to describe them sufficiently so that their geometric features, such as symmetry and proportion as well as structural features, such as thrusts, loads, tensions, compressions and reactions can be analyzed mathematically."

In order to make the book as accessible as possible, Hahn keeps the mathematics simple. The focus is on mathematics that is central to the basic college curriculum: geometry, trigonometry, properties of vectors, coordinate geometry in two and three dimensions and, at the very end, basic calculus.

Hahn's book has received a number of highly favorable reviews, including one in the New York Times Book Review that read, "In examining the crucial interaction between architectural design and his own field on study, Hahn conducts an opulent historical and geographic tour."

For many years, Hahn's research has had a focus on algebraic concerns, in particular on classical matrix groups over fields and number theoretic domains, and on related structures such as quadratic forms and Clifford algebras. More recently, he has been exploring the history of mathematics and science and has authored "Basic Calculus: From Archimedes to Newton to Its Role in Science" and "The Pendulum Swings Again: A Mathematical Reassessment of Galileo's Experiments with Inclined Planes."
