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.
