Nonfiction picture book explains the scientific properties of light, touching on subjects ranging from incandescence and iridescence to light waves and the color spectrum.

"These Rays of Light will inspire people to live a life of purpose and prosperity filled with positive energy. They are truly brilliant and ingenious"-Charles Woodson,2009 NFL Defensive Player of the YearEverything is everythingSee life and "see" lifeMarcus Ray introduces an inspiring way to live a life of purpose via creative, clever, accurate, and enlightening quotes and sayings. He uses the common categories of Knowledge, Wisdom, Understanding, Life, Relationships, Problem-Solving, Self-Help, Perspective, Do not Just because, and Light to guide the reader to see the light and embrace a new perspective on everyday life issues, experiences, and decision-making. Everything in this universe acts on one accord. Marcus Ray calls this concept 'everything is everything'. Rays of Light, Volume 1 "Let There Be Light" puts a different twist on traditional word play and quote books because it explains how everyday life experiences and everyday life activities are simply one in the same. If you live your life the same way you drive your car, there will be less life accidents. Rays of Light, Volume 1 "Let There Be Light" is full of energy, which is the fuel that drives the ship on this journey we call life. This non-traditional quote book encourages people to think on another level and view things in the physical with abstract eyes. Readers will handle situations more wisely and capture a new outlook on life. Look with your eyes, but see with your mind. Come out of the dark and enter the world of light.

What’s in the dark? Countless generations have gazed up at the night sky and asked this question—the same question that cosmologists ask themselves as they study the universe. The answer turns out to be surprising and rich. The space between stars is filled with an exotic substance called “dark matter” that exerts gravity but does not emit, absorb, or reflect light. The space between galaxies is rife with “dark energy” that creates a sort of cosmic antigravity causing the expansion of the universe to accelerate. Together, dark matter and dark energy account for 95 percent of the content of the universe. News reporters and science journalists routinely talk about these findings using terms that they assume we have a working knowledge of, but do you really understand how astronomers arrive at their findings or what it all means? Cosmologists face a conundrum: how can we study substances we cannot see, let alone manipulate? A powerful approach is to observe objects whose motion is influenced by gravity. Einstein predicted that gravity can act like a lens to bend light. Today we see hundreds of cases of this—instances where the gravity of a distant galaxy distorts our view of a more distant object, creating multiple images or spectacular arcs on the sky. Gravitational lensing is now a key part of the international quest to understand the invisible substance that surrounds us, penetrates us, and binds the universe together. A Ray of Light in a Sea of Dark Matter offers readers a concise, accessible explanation of how astronomers probe dark matter. Readers quickly gain an understanding of what might be out there, how scientists arrive at their findings, and why this research is important to us. Engaging and insightful, Charles Keeton gives everyone an opportunity to be an active learner and listener in our ever-expanding universe. Watch a video with Charles Keeton: Watch video now.

My brother is an idiot. He won the lottery and invested all of his money in a run-down bowling alley. Since he's barely making it, he moved in with me. Great. Having him around the house isn't the worst thing in the world, but he does make a mess like nobody's business. My friends Zeke, Jessie, and Kayden keep me sane but there's only so much they can do. And it's definitely not the worst thing in the world when his old friend, Ryker, moves to town. The second I lay eyes on him, I'm hot under the collar. He makes my body burn in longing and freeze in desperation at the exact same time. When he talks, I don't listen to anything he says because I'm staring at that hard jaw and those kissable lips like I already own them. But he's a bed hopper. A playboy. A heartbreaker. I'm all down for some hot, sweaty, yummy sex even if it doesn't have a fairy tale ending. I've been down that road before. I know the drill. But with Ryker, it's different. Because I know I'll fall in love with him. For now, I'll steer clear of him and keep my hands to myself. It can't be that hard, right? Or can it?

A boy rides a bicycle down a dusty road. But in his mind, he envisions himself traveling at a speed beyond imagining, on a beam of light. This brilliant mind will one day offer up some of the most revolutionary ideas ever conceived. From a boy endlessly fascinated by the wonders around him, Albert Einstein ultimately grows into a man of genius recognized the world over for profoundly illuminating our understanding of the universe. Jennifer Berne and Vladimir Radunsky invite the reader to travel along with Einstein on a journey full of curiosity, laughter, and scientific discovery. Parents and children alike will appreciate this moving story of the powerful difference imagination can make in any life.

University Physics is a three-volume collection that meets the scope and sequence requirements for two- and three-semester calculus-based physics courses. Volume 1 covers mechanics, sound, oscillations, and waves. Volume 2 covers thermodynamics, electricity and magnetism, and Volume 3 covers optics and modern physics. This textbook emphasizes connections between between theory and application, making physics concepts interesting and accessible to students while maintaining the mathematical rigor inherent in the subject. Frequent, strong examples focus on how to approach a problem, how to work with the equations, and how to check and generalize the result. The text and images in this textbook are grayscale.

The blistering story of a young man making his Broadway debut in Henry IV just as his marriage implodes—a "witty, wise, and heartfelt novel" (Washington Post) about art and love, fame and heartbreak from the acclaimed actor/writer/director. A bracing meditation on fame and celebrity, and the redemptive, healing power of art; a portrait of the ravages of disappointment and divorce; a poignant consideration of the rites of fatherhood and manhood; a novel soaked in rage and sex, longing and despair; and a passionate love letter to the world of theater, A Bright Ray of Darkness showcases Ethan Hawke's gifts as a novelist as never before. Hawke's narrator is a young man in torment, disgusted with himself after the collapse of his marriage, still half hoping for a reconciliation that would allow him to forgive himself and move on as he clumsily, and sometimes hilariously, tries to manage the wreckage of his personal life with whiskey and sex. What saves him is theater: in particular, the challenge of performing the role of Hotspur in a production of Henry IV under the leadership of a brilliant director, helmed by one of the most electrifying—and narcissistic—Falstaff's of all time. Searing, raw, and utterly transfixing, A Bright Ray of Darkness is a novel about shame and beauty and faith, and the moral power of art.
