The cell is the basic building block of life. In its 3.5 billion years on the planet, it has proven to be a powerhouse, spreading life first throughout the seas, then across land, developing the rich and complex diversity of life that populates the planet today.

The power of images to represent the unseeable: stunning visualizations of science, from the microscopic to the incredibly vast.We live among patterns of delicate beauty and exquisite chaos that our eyes can't detect; we are surrounded by invisible particles and shifting fields of matter that permeate all of space. Our very cells are intricate molecular machines, and the story of our origins stretches back through an unimaginable amount of time. How can we see the richness of what lies beyond our sensory perception? Scientists have developed visualization tools that can make the invisible visible. This bountifully illustrated book demonstrates the power of images to represent the unseeable, offering stunning visualizations of science that range from the microscopic to the incredibly vast. With more than 200 color images and an engaging text by leading science writer Jack Challoner, Seeing Science explains and illustrates the techniques by which scientists create visualizations of their discoveries. We see the first detection of a black hole as represented by an image from an Xray telescope, get a direct view of DNA through an electron microscope, and much more. Visualizations are also used to make sense of an avalanche of data-concisely presenting information from the 20,000 or so human genes, for example. Scientists represent complex theories in computer models, which take on a curious beauty of their own. And scientists and artists collaborate to create art from science visualizations, with intriguing results.

The history of the world through 1,001 inventions—from prehistoric times to the present day.1001 Inventions That Changed the World is an enthralling guide to the world’s most important scientific and technological advances. Authoritatively written by a team of historians, scientists, and anthropologists, this book tells the stories behind these innovations, presenting a comprehensive history of the world through invention and discovery. From stone tools and fire at the dawn of humankind to today’s self-driving cars, inventions have moved society forward at a remarkable pace. This informative volume shows just how much some of the inventions that we take for granted have transformed the world.

An accessible and engaging guide to the atom, the smallest, most fundamental constituent of matter.

The story of the most abundant substance on Earth, from its origins in the birth of stars billions of years ago to its importance in the living world.Water is so ubiquitous in our lives that it is easy to take for granted. The average American uses ninety gallons of water a day; nearly every liquid we encounter is mostly water--milk, for example, is 87 percent water. Clouds and ice--water in other forms--affect our climate. Water is the most abundant substance on Earth, and the third-most abundant molecule in the universe. In this lavishly illustrated volume, science writer Jack Challoner tells the story of water, from its origins in the birth of stars to its importance in the living world.Water is perhaps the most studied compound in the universe--although mysteries about it remain--and Challoner describes how thinkers from ancient times have approached the subject. He offers a detailed and fascinating look at the structure and behavior of water molecules, explores the physics of water--explaining, among other things, why ice is slippery--and examines the chemistry of water. He investigates photosynthesis and water's role in evolutionary history, and discusses water and weather, reviewing topics that range from snowflake science to climate change. Finally, he considers the possibility of water beyond our own hydrosphere--on other planets, on the Moon, in interstellar space.
