Paul Davies, the British physicist who brightened up the Australian science scene when he was a professor at the University of Adelaide in the 1990s, is currently director of the Beyond Center for Fundamental Concepts in Science at Arizona State University. Beyond describes itself as ‘a pioneering center devoted to confronting the really big questions of science and philosophy’. It also aims to present science publicly ‘as a key component of our culture and of significance to all humanity’, something Davies has been doing for thirty years, in popular talks, articles, and books such as About Time (1995).

Were you one of those reluctant mathematics students who complained, ‘What’s the point of all this?’ If so, rest assured: Michael Brooks has made a compelling case for the role mathematics has played in making ‘civilisation’ possible. If you still need convincing, he also discusses research suggesting that doing maths is good for your brain.

Theoretical physicist Carlo Rovelli has a gift for writing short, conversational, popular physics books. His earlier works, notably Seven Brief Lessons in Physics (2015) and The Order of Time (2018), have been bestsellers, and Helgoland is continuing the trend.

If you have ever wondered about the imaginative, wondrous side of science – for instance, how Einstein used maths to predict the existence of gravitational waves, or how a metaphor led to the astonishing discovery that the spinning earth drags space-time around it like molasses around a spoon, this is not the book for you. But if you want to know why scientists had the patience to keep refining their experiments until they detected this barely perceptible rippling of space-time, or why they have the kind of grit made legendary by Marie and Pierre Curie, sifting through tonnes of pitchblende for a speck of radium, you will find an intriguing, bold, and controversial answer in The Knowledge Machine.

Celestial Tapestry is a gem, indeed, a trove of gems: lavishly illustrated cameos from the science and history of art and mathematics, woven into a narrative about pattern and symmetry. We humans have an innate appreciation of symmetry, judging from 5,000 years of art, architecture, mathematics, and mythical and religious symbolism. After all, symmetry is all around us – in the shapes of our bodies, snowflakes, and seashells, and in the fractal-like branching of twigs and blood vessels. In its abstract, mathematical form, symmetry even underlies our modern theories of fundamental physics.

Imagine you’re trying to make sense of the universe five hundred years ago, when astronomers believe there are just seven visible ‘planets’ wandering about the Earth: the sun and moon plus Mercury to Saturn. Intriguingly, there are also seven known metals: gold, silver, copper, iron, tin, lead, and mercury. For hundreds of years there have been just seven known ‘planets’ and seven metals. Wouldn’t you be just a little tempted to see more than a coincidence here? Take gold, for example, which ‘does not react with anything in the air or the ground, and so retains its brilliance seemingly forever’: surely its power is similar to that of the ever-shining sun?

Reading good science writing is not just pleasurable and informative: it’s also necessary if we want to live engaged and examined lives in today’s hyper-technological, climate-changing world. The Best Australian Science Writing 2019 offers readers all these things – the delight in good writing, the satisfaction of learning, and the sobering reckoning with our society’s environmental impact and lack of political engagement with science. Yet it’s not afraid to challenge science itself on occasion – showing ‘its flaws as well as its finer moments’, as editor Bianca Nogrady puts it.

Galileo and Kepler went down in history for prising European science from the jaws of medieval mysticism and religion. But where was England’s equivalent? Newton would not make his mark for another century. Surely the free-thinking Elizabethans also had a scientific star?

They did: Thomas Harriot (c.1560–1621). Most of us have never heard of him, for Harriot did not publish his findings. His day job was teaching navigation to Sir Walter Raleigh’s ship captains. Queen Elizabeth’s favourite was intent on colonising North America for the Crown. But it was also down to Harriot’s personality: retiring, cautious, and meticulous.
