The Powerhouse Museum, Sydney attracts over one million visitors annually to exhibitions that stimulate, challenge, inform and entertain. The heart of the museum is its important, wide-ranging and varied collection of objects tracing the history of design and technology. In this book, Terence Measham, former Director of the Powerhouse Museum, presents a selection of treasures from the fascinating collection. His lively analysis of the historical, social, scientific, industrial and artistic significance of these objects and their connections with one another is engaging and thought-provoking. This is a book about champions - past and present - whose inventions and developments have represented huge strides in science and technology; whose designs have changed our way of living and seeing; whose exploration and endeavour have caused us to know our world better; and whose courage and deeds have served to make the world a better place. Lavishly illustrated in full colour throughout, this book presents a tantalizing glimpse into the vast collection of the Powerhouse Museum.
