    She and her husband packed their bags and their children, and headed for Dublin.When Caroline first started in medicine, being an unmarried mother was frowned on, cane toads were used for pregnancy tests, and giving birth was much riskier than it is today. Her funny and poignant stories of bringing babies into the world show that, while much has changed, women still work hard and it remains a bloody business. A birth plan is no guarantee of a normal birth (whatever that is). Men have always wanted to control women's bodies, and Caroline has been instrumental in giving Australian women of all backgrounds the opportunity to resist, and to choose when and how they have babies. Her behind-the-scenes stories reveal it's often the little things that win a campaign.

    In a time of uncertainty, the country chose in 2019 to turn to a man with no obvious beliefs, no clear purpose and no famous talents. That we wanted Scott Morrison was the secret we did not know about ourselves. What precisely that secret is forms the subject of this book.In The Game, Sean Kelly gives us a portrait of a man, the shallow political culture that allowed him to succeed and the country that crowned him.Morrison understands – in a way that no other recent politician has – how politics has become a game. He also understands something essential about Australia – something many of us are unwilling to admit, even to ourselves.But there are things Scott Morrison does not understand. This is the story of those failures, too – and the way that, as his prime ministership continues, Morrison’s failure to think about politics as anything other than a game has become a dangerous liability, both to him and to us. ‘An engrossing, illuminating and often disquieting study of Scott Morrison. Sean Kelly’s forensic analysis of the man he describes as the “symbolic perfection of a certain version of Australia ” compels us all to consider our complicity in his creation.’—Niki Savva‘It’s been almost impossible to get a handle on Scott Morrison. Until now. Sean Kelly has done it, comprehensively.’ —Barrie Cassidy‘Sean Kelly exposes Morrison with wit and righteous precision. After reading this insightful, funny and absolutely maddening dissection of the man, I can now clearly see him for what he is.’ —Tom Ballard

    Starting with Ptolemy, "father of modern geography," and ending with satellite cartography, A History of the World in 12 Maps brings maps from classical Greece, Renaissance Europe, and the Islamic and Buddhist worlds to life and reveals their influence on how we—literally—look at our present world. As Brotton shows, the long road to our present geographical reality was rife with controversy, manipulation, and special interests trumping science. Through the centuries maps have been wielded to promote any number of imperial, religious, and economic agendas, and have represented the idiosyncratic and uneasy fusion of science and subjectivity. Brotton also conjures the worlds that produced these notable works of cartography and tells the stories of those who created, used, and misused them for their own ends.

    In a society obsessed with natural history and the discovery of new species, the birdman’s wife was at its glittering epicentre. Her artistry breathed life into hundreds of exotic finds, from her husband’s celebrated collections to Charles Darwin’s famous Galapagos finches.Fired by Darwin’s discoveries, in 1838 Elizabeth defied convention by joining John on a trailblazing expedition to the untamed wilderness of Van Diemen’s Land and New South Wales to collect and illustrate Australia’s ‘curious’ birdlife.From a naïve and uncertain young girl to a bold adventurer determined to find her own voice and place in the world, The Birdman’s Wife paints an indelible portrait of an extraordinary woman overlooked by history, until now.

    In this simple pattern beginning with two ones, each succeeding number is the sum of the two numbers immediately preceding it (1, 1, 2, 3, 5, 8, 13, 21, ad infinitum). Far from being just a curiosity, this sequence recurs in structures found throughout nature - from the arrangement of whorls on a pinecone to the branches of certain plant stems. All of which is astounding evidence for the deep mathematical basis of the natural world. With admirable clarity, two veteran math educators take us on a fascinating tour of the many ramifications of the Fibonacci numbers. They begin with a brief history of a distinguished Italian discoverer, who, among other accomplishments, was responsible for popularizing the use of Arabic numerals in the West. Turning to botany, the authors demonstrate, through illustrative diagrams, the unbelievable connections between Fibonacci numbers and natural forms (pineapples, sunflowers, and daisies are just a few examples). In art, architecture, the stock market, and other areas of society and culture, they point out numerous examples of the Fibonacci sequence as well as its derivative, the "golden ratio." And of course in mathematics, as the authors amply demonstrate, there are almost boundless applications in probability, number theory, geometry, algebra, and Pascal's triangle, to name a few.Accessible and appealing to even the most math-phobic individual, this fun and enlightening book allows the reader to appreciate the elegance of mathematics and its amazing applications in both natural and cultural settings.
