Was the purpose of an Iron Age hillfort to defend people and resources or was it there to show the power of the community and its leaders? Was the Middle Iron Age trend to large complex ‘defences’ a response to developing tactics of assault or did the huge amounts of construction work serve the purpose of building community identity through shared labour? The name ‘hillfort’ implies a defensive purpose, but in recent decades alternative interpretations have gained favour, based on analyses suggesting that hillforts are poorly suited to military purposes and on views of Iron Age society that emphasise the importance of boundaries, symbolic display and communitybuilding. Excavations of hillfort interiors reveal they were sites for many activities; large caches of stones suggest that sling warfare was one. This book reports an investigation of these issues. Sling accuracy at a hillfort was measured for the first time, in a controlled experiment comparing attack and defence across single and developed ramparts. Tactical scenarios modelled from the results showed that hillfort development gave defenders increased advantage. These results support defence as the explanation for the features of the enclosing works of hillforts. Full details of the method and analyses are included.

The evolution of Australian radio astronomy from 1945 to 1960 has been studied in detail by numerous historians of science in recent years. This Open Access book is the first to present an overview of this remarkable chapter in Australian science. The book begins in the post-war period, as the Radiophysics Laboratory in Sydney switched from secret wartime research on radar to peacetime applications of this new technology. Next follows the detection of radio waves from space and the ensuing transformation of this fledgling science into the dominant research program at the Radiophysics Lab. Drawing from this history, the book shows how by 1960 the Radiophysics Lab had become the largest and most successful radio astronomy group in the world. The final chapter presents an overview of Australian radio astronomy from 1960 to the present day, as Australia prepares to co-host the multi-national, multi-billion-dollar Square Kilometre Array.Nearly 300 high-quality images complement the text, drawn from a wide range of sources including the extensive collection held by the CSIRO Radio Astronomy Image Archive. The book will be an essential reference for readers interested in the scientific and cultural development of radio astronomy.This book is published open access under a CC BY 4.0 license.

Photochemical reactions play a major role in the environment including a wide range of reactions in the atmosphere, natural waters, soil and living organisms. This new volume on Environmental Photochemistry up-dates the previous edition with chapters on basic aspects including concepts of photochemical transformations and mechanistic photochemical processes in the atmosphere and water. In addition a range of applications are also detailed such as advanced photochemical oxidation processes for water and air treatment as well as applications of photocatalysis for surface treatment and nuclear fuel reprocessing. The new edition provides a critical up to date overview of the most important research in the field of environmental photochemistry.
