Introduces a world invisible to the naked eye and discusses the different types of microscopes available, the steps for the preparation and study of specimens, and related topics.

From deep within the human body to distant nebulae in outer space, there are worlds all around us that are smaller, faster, and farther than the unaided eye can see. In these thirty-six amazing images, you can see the invisible: from a white blood cell attacking E. coli bacteria, to the delicate splash from a falling drop of water captured by a high-speed strobe. With pictures that astound and fascinating explanations of how each image was captured, award-winning author Seymour Simon takes readers on a fantastic voyage that's truly out of sight.

With its emphasis on the history and philosophical foundations of physics, this book will interest lay readers as well as students and professionals. The distinguished author discusses pioneers in the field, including Pauli, Einstein, Bohr, and de Broglie. Topics include hidden-variable and causal theories, pilot wave, and Schrödinger's equation. 2013 edition.

No one has ever seen a quark. Yet physicists seem to know quite a lot about the properties and behavior of these ubiquitous elementary particles. Here a top researcher introduces us to a fascinating but invisible realm that is part of our everyday life. Timothy Smith tells us what we know about quarks--and how we know it. Though the quarks that make science headlines are typically laboratory creations generated under extreme conditions, most quarks occur naturally. They reside in the protons and neutrons that make up almost all of the universe's known matter, from human DNA to distant nebulae, from books and tables to neutron stars. Smith explains what these quarks are, how they act, and why physicists believe in them sight unseen. How do quarks arrange themselves? What other combinations can nature make? How do quarks hold nuclei together? What else is happening in their hidden worlds? It turns out that these questions can be answered using a few simple principles, such as the old standby: opposites attract. With these few principles, Smith shows how quarks dance around each other and explains what physicists mean when they refer to "up" and "down" quarks and talk about a quark's color, flavor, and spin. Smith also explains how we know what we know about these oddly aloof particles, which are eternally confined inside larger particles. He explains how quark experiments are mounted and how massive accelerators, targets, and detectors work together to collect the data that scientists use to infer what quarks are up to. A nonmathematical tour of the quark world, this book is written for students, educators, and all who enjoy scientific exploration--whether they seek a taste of subnuclear physics or just wonder about nature on the smallest of scales.

Throughout most of human history, our ancestors have done rather poorly when dealing with acts of violence. To cite but one of many shocking examples, let us perhaps recall a case from 1801, of an English boy aged only 13, who was executed by hanging on the gallows at Tyburn. What was his crime? It seems that he had been condemned to die for having stolen a spoon (Westwick, 1940).

President Theodore Roosevelt called Jacob Riis "the best American I ever knew." The pioneering photojournalist, an immigrant from Denmark, drew attention to the poverty and evils of slum life in the late 1800s. Riis won national acclaim when his photos illustrated his bestselling book How the Other Half Lives. The book focused on the difficult time immigrants faced as thousands of newcomers flooded into the United States each year. Riis called for reform and hoped to prod government officials to help the poor people who were forced to live under horrible conditions. The impact of Riis' photos came from capturing the poor and homeless as they lived and worked, with the subjects' eyes often staring directly into the camera. The great photographer Ansel Adams called them "magnificent achievements in the field of humanistic photography." But the reforms that came from Riis' work have not eliminated urban poverty and homelessness, and important work remains to be done.

Spyder Lee is a happy man who lives in San Francisco and owns a tattoo shop. One night an angry demon tries to bite his head off before he's saved by a stranger. The demon infected Spyder with something awful - the truth. He can suddenly see the world as it really is: full of angels and demons and monsters and monster-hunters. A world full of black magic and mysteries. These are the Dominions, parallel worlds full of wonder, beauty and horror. The Black Clerks, infinitely old and infinitely powerful beings whose job it is to keep the Dominions in balance, seem to have new interests and a whole new agenda. Dropped into the middle of a conflict between the Black Clerks and other forces he doesn't fully understand, Spyder finds himself looking for a magic book with the blind swordswoman who saved him. Their journey will take them from deserts to lush palaces, to underground caverns, to the heart of Hell itself.
