Inka Engineering Symposium 4: Suspension Bridge Technology
Description:
In Part 4 of Engineering the Inka Empire: A Symposium on Sustainability and Ancient Technologies, John Ochsendorf presents Engineering in the Andes: Indigenous Suspension Bridge Technology. The Inka Empire relied on an extensive network of roads and bridges to connect the various regions under Inka control. Though the Inka road system has been studied in some detail, scholars have largely neglected the role of bridges. These functional works enabled the expansion of the Inka Empire and often dictated the location of roads, tambos, and other Inka sites. The role of bridges in Andean history raises important questions and demands greater attention from historians of the built environment. Due to the detailed chronicles of the construction process, suspension bridges provide a unique opportunity for understanding the organization of construction in the Inka Empire. This presentation draws on primary source material from chroniclers' descriptions of the bridges to identify important Inka bridges, explore their origins, and pose questions for future research in Inka engineering. John Ochsendorf has been on the faculty at the Massachusetts Institute of Technology since 2002, and is the Class of 1942 Professor of Architecture and Civil and Environmental Engineering. He earned his Bachelor of Science in structural engineering and archaeology from Cornell University, where his undergraduate thesis carried out the first technical study of Andean suspension bridges. Ochsendorf earned a Master of Science in Civil and Environmental Engineering from Princeton University and a PhD in structural engineering from the University of Cambridge. He is a founding partner of Ochsendorf DeJong and Block LLC, a consulting firm specializing in historical structures. He has won numerous awards for research in structural engineering and architecture, including a Graduate Research Fellowship from the National Science Foundation, a Fulbright Pre-Doctoral Scholarship from the J. William Fulbright Foundation, a Rome Prize from the American Academy in Rome, and a MacArthur Fellowship from the John D. and Catherine T. MacArthur Foundation. This symposium was webcast on November 14, 2013 from the Rasmuson Theater at the National Museum of the American Indian in Washington, D.C.

Inka Engineering Symposium 6: Road Construction Technologies
Description:
In Part 6 of Engineering the Inka Empire: A Symposium on Sustainability and Ancient Technologies, Christine Fiori and Cliff Schexnayder present Road Construction Technology in the High Cordillera. The engineers of the Inka Empire had a unique consciousness of nature, with construction skills founded in lessons learned from careful observation of the power of nature. The Inka Road demonstrates the superior Inka understanding of nature. Built without the use of iron, the wheel, or stock animals, it represents important milestones in the development of civil engineering knowledge. The road's creators understood the fundamental laws of nature and employed impressive engineering strategies in response to the challenges presented by the aggressive physical geography of western South America. The Inka Road, or Qhapaq √Ďan, in scale alone is one of man's monumental engineering achievements. This engineering masterpiece rests on careful attention to the power of water, the energy expended by the users of the road (man and llama), and the energy required to construct the road. Keeping these concepts in mind, with the support of the University of Piura, Peru, and the assistance of Professor Luis Gerardo Chang Recavarren, the researchers investigated the construction techniques employed by the Inkas in the building of the road. Ground penetrating radar technology was employed to assess the subsurface structure of the road, slopes were measured, and grade and width were verified to understand the construction methods utilized. The investigation of the various methods to control water and erosion helped in developing an understanding of why the road has endured for centuries. Christine Fiori is the Associate Director of the Myers-Lawson School of Construction at Virginia Tech. She received her PhD in Civil Engineering with a concentration in Geotechnical Engineering from Drexel University in 1997. Her interest in ancient construction led to a National Science Foundation grant to explore the construction techniques of the Inka, specifically the Inka road throughout Peru. Fiori leads the Construction Engineering and Management program and also facilitates the service learning programs for the Myers-Lawson School of Construction. She has led diverse groups of student teams to Vietnam, Kenya, Belize, Haiti, and Guatemala to complete construction projects and community engagement programs. Currently her work is focused in Haiti and Belize. Cliff Schexnayder (Choctaw) is the Emeritus Eminent Scholar, Del E. Webb School of Construction, Arizona State University. He holds Civil Engineering BS and MS degrees from Georgia Institute of Technology and a PhD from Purdue University. Before entering academia he worked with major heavy/highway construction contractors as field engineer, estimator, and corporate Chief Engineer. In South America he has taught construction engineering at the Universidad de Piura and Ricardo Palma Universidad in Peru. Schexnayder is a member of the National Academy of Construction, the Academia Panamericana de Ingenier√≠a, and is a Distinguished Member of the American Society of Civil Engineers (ASCE). He served as chairman of the ASCE's Construction Division and the Transportation Research Board's Construction Section. This symposium was webcast on November 14, 2013 from the Rasmuson Theater at the National Museum of the American Indian in Washington, D.C.

A History of Pop-up and Movable Books: 700 Years of Paper Engineering (2010) - Ellen G. K. Rubin
Description:
Ellen G. K. Rubin discovered pop-up and movable books when she began reading them to her sons over 25 years ago. Today, she has more than 6,500 books and thousands of uncataloged movable ephemera. While at Yale Medical School's Physican Associate program in 1987, she attended the Sterling Library's exhibition on the history of movable books. It was there that she learned about the scholarly dimensions of her passion. Ellen now lectures and writes about her books, conducts workshops, and curates exhibitions. In 2000, she co-curated Brooklyn Pops Up! The History and Art of the Movable Book at the Brooklyn Public Library. She is a charter member of the Movable Book Society and writes for their newsletter and is a member of the Grolier Club. Ellen hosts her website, The Pop-Up Lady. to disseminate information on the subject.
