All of the Earth's ocean, from the equator to the poles, is a single engine powered by sunlight - a blue machine. Human history has been dictated by the ocean: the location of cities, access to resources and the gateways to new lands have all revolved around water. We live inside the weather the ocean generates and breathe in what it breathes out. Yet despite our dependence, our awareness of its totality is minimal. In a book that will recalibrate our view of this defining feature of our planet, physicist Helen Czerski dives deep to illuminate the murky depths of the ocean engine, examining the messengers, passengers and voyagers that live in it, travel over it, and survive because of it. From the ancient Polynesians who navigated the Pacific by reading the waves to permanent residents of the deep such as the Greenland shark that can live for hundreds of years, she explains the vast currents, invisible ocean walls and underwater waterfalls that all have their place in the ocean's complex, interlinked system. Timely, elegant and passionately argued, The Blue Machine is one of the biggest stories ever told. The understanding it offers is crucial to our future. Drawing on years of experience at the forefront of marine science, Helen Czerski captures the magnitude and subtlety of this complex force, showing us the thrilling extent to which we are at the mercy of this great engine.

All of Earth’s oceans, from the equator to the poles, are a single engine powered by sunlight, driving huge flows of energy, water, life, and raw materials. In The Blue Machine, physicist and oceanographer Helen Czerski illustrates the mechanisms behind this defining feature of our planet, voyaging from the depths of the ocean floor to tropical coral reefs, estuaries that feed into shallow coastal seas, and Arctic ice floes. Through stories of history, culture, and animals, she explains how water temperature, salinity, gravity, and the movement of Earth’s tectonic plates all interact in a complex dance, supporting life at the smallest scale—plankton—and the largest—giant sea turtles, whales, humankind. From the ancient Polynesians who navigated the Pacific by reading the waves, to permanent residents of the deep such as the Greenland shark that can live for hundreds of years, she introduces the messengers, passengers, and voyagers that rely on interlinked systems of vast currents, invisible ocean walls, and underwater waterfalls. Most important, however, Czerski reveals that while the ocean engine has sustained us for thousands of years, today it is faced with urgent threats. By understanding how the ocean works, and its essential role in our global system, we can learn how to protect our blue machine. Timely, elegant, and passionately argued, The Blue Machine presents a fresh perspective on what it means to be a citizen of an ocean planet.

'A quite delightful book on the joys, and universality, of physics. Czerski's enthusiasm is infectious because she brings our humdrum everyday world to life, showing us that it is just as fascinating as anything that can be seen by the Hubble Telescope or created at the Large Hadron Collider.' - Jim Al-Khalili Our world is full of patterns. If you pour milk into your tea and give it a stir, you'll see a swirl, a spiral of two fluids, before the two liquids mix completely. The same pattern is found elsewhere too. Look down on the Earth from space, and you'll find similar swirls in the clouds, made where warm air and cold air waltz. In Storm in a Teacup, Helen Czerski links the little things we see every day with the big world we live in. Each chapter begins with something small - popcorn, coffee stains and refrigerator magnets - and uses it to explain some of the most important science and technology of our time. This is physics as the toolbox of science - a toolbox we need in order to make sense of what is around us and arrive at decisions about the future, from medical advances to solving our future energy needs. It is also physics as the toy box of science: physics as fun, as never before.

Part of the new Ladybird Expert series, Bubbles is a clear, surprising and entertaining introduction to the science of bubbles. Bubbles are beautiful, ephemeral, fun, fragile, jolly and slightly unpredictable. We're all familiar with them, but we don't often ask what they actually are. The great scientists of the Western world - Robert Hooke, Isaac Newton, Lord Rayleigh and more - studied bubbles seriously. They recognised that they had a lot to say about the nature of the physical world, and they poked, prodded and listened to find out what it was. In the years since, we've learned that this bulbous arrangement of liquid and gas does things that neither the gas or the liquid could do by itself. Written by the celebrated physicist and oceanographer Helen Czerski, Bubbles explores how everything from the way drinks taste to the Earth's temperature are influenced by bubbles. This book has a message: never underestimate a bubble! Written by the leading lights and most outstanding communicators in their fields, the Ladybird Expert books provide clear, accessible and authoritative introductions to subjects drawn from science, history and culture. For an adult readership, the Ladybird Expert series is produced in the same iconic small hardback format pioneered by the original Ladybirds. Each beautifully illustrated book features the first new illustrations produced in the original Ladybird style for nearly forty years.
