This book presents a systematic design methodology for decoding the interior structure of the Antikythera mechanism, an astronomical device from ancient Greece. The historical background, surviving evidence and reconstructions of the mechanism are introduced, and the historical development of astronomical achievements and various astronomical instruments are investigated. Pursuing an approach based on the conceptual design of modern mechanisms and bearing in mind the standards of science and technology at the time, all feasible designs of the six lost/incomplete/unclear subsystems are synthesized as illustrated examples, and 48 feasible designs of the complete interior structure are presented. This approach provides not only a logical tool for applying modern mechanical engineering knowledge to the reconstruction of the Antikythera mechanism, but also an innovative research direction for identifying the original structures of the mechanism in the future. In short, the book offers valuable new insights for all readers who are interested in the Antikythera mechanism.

These proceedings collect the latest research results in mechanism and machine science, intended to reinforce and improve the role of mechanical systems in a variety of applications in daily life and industry. Gathering more than 120 academic papers, it addresses topics including: Computational kinematics, Machine elements, Actuators, Gearing and transmissions, Linkages and cams, Mechanism design, Dynamics of machinery, Tribology, Vehicle mechanisms, dynamics and design, Reliability, Experimental methods in mechanisms, Robotics and mechatronics, Biomechanics, Micro/nano mechanisms and machines, Medical/welfare devices, Nature and machines, Design methodology, Reconfigurable mechanisms and reconfigurable manipulators, and Origami mechanisms. This is the fourth installment in the IFToMM Asian conference series on Mechanism and Machine Science (ASIAN MMS 2016). The ASIAN MMS conference initiative was launched to provide a forum mainly for the Asian community working in Mechanism and Machine Science, in order to facilitate collaboration and improve the visibility of activities in the field. The series started in 2010 and the previous ASIAN MMS events were successfully held in Taipei, China (2010), Tokyo, Japan (2012), and Tianjin, China (2014). ASIAN MMS 2016 was held in Guangzhou, China, from 15 to 17 December 2016, and was organized by the South China University under the patronage of the IFToMM and the Chinese Mechanical Engineering Society (CMES). The aim of the Conference was to bring together researchers, industry professionals and students from the broad range of disciplines connected to Mechanism Science in a collegial and stimulating environment. The ASIAN MMS 2016 Conference provided a platform allowing scientists to exchange notes on their scientific achievements and establish new national and international collaborations concerning the mechanism science field and its applications, mainly but not exclusively in Asian contexts.

Completely revised and updated, this new edition provides a readable, beautifully illustrated journey through world cultures and the vibrant array of sky mythology, creation stories, models of the universe, temples and skyscrapers that each culture has created to celebrate and respond to the power of the night sky. Sections on the archaeoastronomy of South Asia and South East Asia have been expanded, with original photography and new research on temple alignments in Southern India, and new material describing the astronomical practices of Indonesia, Malaysia and other Southeast Asian countries. Beautiful photographs of temples in India and Asia have been added, as well as new diagrams explaining the alignment of these structures and the astronomical underpinnings of temples within the Pallava and Chola cultures. From new fieldwork in the Four Corners region of North America, Dr. Penprase has included accounts of Pueblo skywatching and photographs of ceremonial kivas that help elucidate the rich astronomical knowledge of the Pueblo people. The popular “Archaeoastronomy of Skyscrapers” section of the book has been updated as well, with new interpretations of skyscrapers in Indonesia, Taiwan and China.With the rapid pace of discovery in astronomy and astrophysics, entirely new perspectives are emerging about dark matter, inflation and the future of the universe. The Power of Stars puts these discoveries in context and describes how they fit into the modern perspective of cosmology, which has arisen from the universal human response to the sky that has inspired both ancient and modern cultures.

In 1900 a group of sponge divers blown off course in the Mediterranean discovered an Ancient Greek shipwreck dating from around 70 BC. Lying unnoticed for months amongst their hard-won haul was what appeared to be a formless lump of corroded rock, which turned out to be the most stunning scientific artefact we have from antiquity. For more than a century this 'Antikythera mechanism' puzzled academics, but now, more than 2000 years after the device was lost at sea, scientists have pieced together its intricate workings. In Decoding the Heavens, Jo Marchant tells for the first time the story of the 100-year quest to understand this ancient computer. Along the way she unearths a diverse cast of remarkable characters - ranging from Archimedes to Jacques Cousteau - and explores the deep roots of modern technology not only in Ancient Greece, the Islamic world and medieval Europe.

Unmatched in complexity for 1000 years, it was able to predict eclipses and track the paths of the Sun and the Moon through the zodiac, and probably even showed ancient astronomers the movements of the five known planets. In Decoding the Heavens, Jo Marchant tells for the first time the story of the 100-year quest to understand this ancient computer.

At heart an epic adventure story, it is a book that challenges our assumption
