Blue Machine

FINANCIAL TIMES 2023 HIGHLIGHT'Helen Czerski weaves together physics and biology, history and science, in a beautifully poetic way.'Professor Alice Roberts'In Helen Czerski's hands, the mechanical becomes magical. An instant classic.'Tristan Gooley, author of How to Read Water'Blue Machine is quite simply one of the best books I have ever read.'Dr George McGavin, zoologist, entomologist and broadcaster'A fascinating dive into the essential engine that drives our world. Czerski brings the oceans alive with compelling stories that masterfully navigate this most complex system.'Gaia Vince, science journalist, broadcaster and author of Nomad Century All of the Earth's ocean, from the equator to the poles, is a single engine powered by sunlight - a blue machine.Earth is home to a huge story that is rarely told - that of our ocean. Not the fish or the dolphins, but the massive ocean engine itself: what it does, why it works, and the many ways it has influenced animals, weather and human history & culture.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, Blue Machine presents a fresh perspective on what it means to be a citizen of an ocean planet. 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 Earth's defining feature, showing us the thrilling extent to which we are at the mercy of this great engine.

A spectacular read., [Czerski's] profound, sparkling global ocean voyage mingles history and culture, natural history, geography, animals and people., 'Czerski aims to greatly expand and even revolutionise the reader's understanding of what is going on in seven tenths of the planet that is not covered in land, Lively and engrossing ... Alongside her vivid portrayal of waters sliding over one another, colliding, mixing andturning into ice or water vapour, she explains how the living beings within the sea alsoform part of the 'blue machine' ... [Cerzski's personal experience of both Polynesian canoes off Hawaii and ice floes near the North Pole is not icing on the cake but part of the argument of this excellent and important book., Helen Czerski's fascinating new book casts the ocean as an extraordinary giant engine, and helps us grasp its complex physicsand its key role in climate change

Helen Czerski was born in Manchester. She is an Associate Professor in the Department of Mechanical Engineering at University College London. As a physicist, she studies the bubbles generated by breaking waves in the ocean to understand their influence on weather and climate.Helen has been a regular presenter of BBC TV science documentaries since 2011. She also hosts the Ocean Matters podcast, is part of the Cosmic Shambles network, and is one of the presenters for the Fully Charged Show. She has been a science columnist for the Wall Street Journal since 2017 and she is the author of the bestselling Storm in a Teacup: The Physics of Everyday Life, Bubbles: A Ladybird Expert Book, and Blue Machine: how the ocean shapes our world.
