The highly-anticipated paperback edition of The Elements is finally available.
An eye-opening, original collection of gorgeous, never-before-seen photographic representations of the 118 elements in the periodic table.
The elements are what we, and everything around us, are made of. But how many elements has anyone actually seen in pure, uncombined form? The Elements provides this rare opportunity. Based on seven years of research and photography, the pictures in this book make up the most complete, and visually arresting, representation available to the naked eye of every atom in the universe. Organized in order of appearance on the periodic table, each element is represented by a spread that includes a stunning, full-page, full-color photograph that most closely represents it in its purest form. For example, at -183°C, oxygen turns from a colorless gas to a beautiful pale blue liquid.
Also included are fascinating facts, figures, and stories of the elements as well as data on the properties of each, including atomic weight, density, melting and boiling point, valence, electronegativity, and the year and location in which it was discovered. Several additional photographs show each element in slightly altered forms or as used in various practical ways. The element's position on the periodic table is pinpointed on a mini rendering of the table and an illustrated scale of the element's boiling and/or melting points appears on each page along with a density scale that runs along the bottom.
Packed with interesting information, this combination of solid science and stunning artistic photographs is the perfect gift book for every sentient creature in the universe.
Includes a tear-out poster of Theodore Gray's iconic Photographic Periodic Table!
Brox plumbs the class implications of light—who had it, who didn’t—through the many centuries when crude lamps and tallow candles constricted waking hours. She convincingly portrays the hell-bent pursuit of whale oil as the first time the human desire for light thrust us toward an environmental tipping point. Only decades later, gas street lights opened up the evening hours to leisure, which changed the ways we live and sleep and the world’s ecosystems.
Edison’s “tiny strip of paper that a breath would blow away” produced a light that seemed to its users all but divorced from human effort or cost. And yet, as Brox’s informative and hair-raising portrait of our current grid system shows, the cost is ever with us.
Brilliant is infused with human voices, startling insights, and—only a few years before it becomes illegal to sell most incandescent light bulbs in the United States—timely questions about how our future lives will be shaped by light.
If you sit as still as you can in a quiet room, you might be able to convince yourself that nothing is moving. But air currents are still wafting around you. Blood rushes through your veins. The atoms in your chair jiggle furiously. In fact, the planet you are sitting on is whizzing through space thirty-five times faster than the speed of sound.
Natural motion dominates our lives and the intricate mechanics of the world around us. In ZOOM, Bob Berman explores how motion shapes every aspect of the universe, literally from the ground up. With an entertaining style and a gift for distilling the wondrous, Berman spans astronomy, geology, biology, meteorology, and the history of science, uncovering how clouds stay aloft, how the Earth's rotation curves a home run's flight, and why a mosquito's familiar whine resembles a telephone's dial tone.
For readers who love to get smarter without realizing it, ZOOM bursts with science writing at its best.

This book is comprised of five chapters and begins with an overview of the fundamentals of holography, with particular reference to spatial and temporal coherence, diffraction at finite and infinite distances, and filtering of spatial frequencies. The reader is then introduced to the principles and applications of holography, focusing on the geometric optics and aberrations of holograms as well as interferometry and microscopy. The following chapters explore how images are produced and reconstructed using a hologram and explain how to detect the differences between two images. Three main types of synthetic holograms are also considered: binary holograms, holograms with several intensity levels, and the holograms called kinoforms. The last chapter is devoted to optical filtering and pattern recognition.
This monograph will be of value to physicists and researchers as well as to those interested in how holography works.

In The Edge of Physics, a science writer journeys to the ends of the Earth—visiting remote and sometimes dangerous places—in search of the telescopes and detectors that promise to answer the biggest questions in modern cosmology.
Anil Ananthaswamy treks to the Atacama Desert in the Chilean Andes, one of the coldest, driest places on the planet, where not even a blade of grass can survive, and the spectacularly clear skies and dry atmosphere allow astronomers to gather brilliant images of galaxies billions of light-years away. He takes us inside the European Organisation for Astronomical Research in the Southern Hemisphere’s Very Large Telescope on Mount Paranal, where four massive domes open to the sky each night “like a dragon waking up.”
Ananthaswamy also heads deep inside an abandoned iron mine in Minnesota—where half-mile-thick rock shields physicists as they hunt for elusive dark matter particles. And to the East Antarctic Ice Sheet, where engineers are drilling 1.5 miles into the clearest ice on the planet. They are building the world’s largest neutrino detector, which could finally help reconcile quantum physics with Einstein’s theory of general relativity. The stories of the people who work at these and other research sites make for a compelling new portrait of the universe—and our quest to understand it.
“From the top of Hawaii’s Mauna Kea to Switzerland’s Large Hadron Collider and more, Ananthaswamy paints a vivid picture of scientific investigations in harsh working conditions. . . . Even for readers who don’t know a neutrino from Adam, these interesting tales of human endeavor make The Edge of Physics a trip worth taking.” —Bookpage
“Ananthaswamy journeys to several geographically and scientifically extreme outposts, and returns not only with engaging portraits of the men and women who work there, but also a vibrant glimpse of how cutting-edge research is actually performed. Part history lesson, part travelogue, part adventure story, ‘The Edge of Physics’ is a wonder-steeped page-turner.” —Seed Magazine
“Ananthaswamy displays a writer’s touch for the fascinating detail.” —The Washington Post
