Bøger af Helen Czerski

Just as Freakonomics brought economics to life, so Storm in a Teacup brings physics into our daily lives and makes it fascinating. Not so, insists Helen Czerski - and in this sparkling new book she explores the patterns and connections that illustrate the grandest theories in the smallest everyday objects and experiences.

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.

Storm in a Teacup is Helen Czerski's lively, entertaining, and richly informed introduction to the world of physics. Czerski provides the tools to alter the way we see everything around us by linking ordinary objects and occurrences, like popcorn popping, coffee stains, and fridge magnets, to big ideas like climate change, the energy crisis, or innovative medical testing. She provides answers to vexing questions: How do ducks keep their feet warm when walking on ice? Why does it take so long for ketchup to come out of a bottle? Why does milk, when added to tea, look like billowing storm clouds? In an engaging voice at once warm and witty, Czerski shares her stunning breadth of knowledge to lift the veil of familiarity from the ordinary.
