A charming and captivating exploration of the science of light. Where does light come from? How does it work? What is it made of? A girl and her cat find answers to these questions on a summertime journey of scientific discovery. The pair identify loads of examples of light, while exploring many fascinating topics: natural and artificial light; uses of light; opaque, translucent and transparent objects; absorbed, reflected and refracted light; and how the eye sees light. It’s a gentle yet comprehensive introduction to light and all its mysteries. From stars in the sky to fireworks over a lake, our inquisitive guides shine a light on … light!

In this charming picture book for young children, the magic of Shabbat is celebrated through light. As the sun goes down on a Friday evening and darkness descends, different sources of light welcome in the Sabbath: candles, lanterns, the moon and stars, fireflies, nightlights and then the next morning, the sunrise. Told in gently rhythmic rhyming couplets and beautifully illustrated throughout, this is an enchanting exploration of light and dark, and a journey through the various rituals and delights of Shabbat.

If you look very carefully at the night sky, you might spot a teeny-tiny sparkle out of the corner of your eye, a whisper of a tinkling trail. That's Ella. Ella has always dreamed of seeing the sunrise. But with her delicate gossamer wings, she can only come out at night. So, when the moon is high, she collects as many shimmering beams of light she can find - a twinkle from a star, the glow from a lamp post. With her light, she guides lost and lonely animals and finds friendship in Fox and Owl. And, together, Ella's animal friends know just how to return her kindness.

While certain ecological problems associated with artificial night lighting are widely known-for instance, the disorientation of sea turtle hatchlings by beachfront lighting-the vast range of influences on all types of animals and plants is only beginning to be recognized. From nest choice and breeding success of birds to behavioral and physiological changes in salamanders, many organisms are seriously affected by human alterations in natural patterns of light and dark. Ecological Consequences of Artificial Night Lighting is the first book to consider the environmental effects of the intentional illumination of the night. It brings together leading scientists from around the world to review the state of knowledge on the subject and to describe specific effects that have been observed across a full range of taxonomic groups, including mammals, birds, reptiles and amphibians, fishes, invertebrates, and plants. Ecological Consequences of Artificial Night Lighting provides a scientific basis to begin addressing the challenge of conserving the nighttime environment. It cogently demonstrates the vital importance of this until-now neglected topic and is an essential new work for conservation planners, researchers, and anyone concerned with human impacts on the natural world.

A gripping and deftly plotted narrative of family and belonging, Lights All Night Long is a dazzling debut novel from an acclaimed young writer "A luminous debut. . . .

The abundance of his new world--the Super Walmarts and heated pools and enormous televisions--is as hard to fathom as the relentless cheerfulness of his host parents. And Sadie, their beautiful and enigmatic daughter, has miraculously taken an interest in him. But all is not right in Ilya's world: he's consumed by the fate of his older brother Vladimir, the magnetic rebel to Ilya's dutiful wunderkind, back in their tiny Russian hometown. The two have always been close, spending their days dreaming of escaping to America. But when Ilya was tapped for the exchange, Vladimir disappeared into their town's seedy, drug-plagued underworld. Just before Ilya left, the murders of three young women rocked the town's usual calm, and Vladimir found himself in prison. With the help of Sadie, who has secrets of her own, Ilya embarks on a mission to prove Vladimir's innocence. Piecing together the timeline of the murders and Vladimir's descent into addiction, Ilya discovers the radical lengths to which Vladimir has gone to protect him--a truth he could only have learned by leaving him behind. A rich tale of belonging and the pull of homes both native and adopted, Lights All Night Long is a spellbinding story of the fierce bond between brothers determined to find a way back to each other.

Light and darkness shape our perception of the world. This is true in a literal sense, but also metaphorically: in theology, philosophy, literature and the arts the light of day signifies life, safety, knowledge and all that is good, while the darkness of the night suggests death, danger, ignorance and evil. A closer inspection, however, reveals that things are not quite so clear cut and that light and darkness cannot be understood as simple binary opposites. On a biological level, for example, daylight and darkness are inseparable factors in the calibration of our circadian rhythms, and a lack of periodical darkness appears to be as contrary to health as a lack of exposure to sunlight. On a cultural level, too, night and darkness are far from being universally condemnable: in fiction, drama and poetry the darkness of the night allows not only nightmares but also dreams, it allows criminals to ply their trade and allows lovers to meet, it allows the pursuit of pleasure as well as deep thought, it allows metamorphoses, transformations and transgressions unthinkable in the light of day. But night is not merely darkness. The night gains significance as an alternative space, as an ‘other of the day’, only when it is at least partially illuminated. The volume examines the interconnection of night, darkness and nocturnal illumination across a broad range of literary texts. The individual essays examine historically specific light conditions in literature, tracing the symbolic and metaphoric content of darkness and illumination and the attitudes towards them.

Night games transformed the business of professional baseball, as the smaller, demographically narrower audiences able to attend daytime games gave way to larger, more diversified crowds of nighttime spectators. Many ball club owners were initially conflicted about artificial lighting and later actually resisted expanding the number of night games during the sport's struggle to balance ballpark attendance and television viewership in the 1950s. This first-ever comprehensive history of night baseball examines the factors, obstacles and trends that shaped this dramatic change in both the minor and major leagues between 1930 and 1990.
