Light after Dark III: The Mathematics of Gravity and Quanta proves the most important results described in Light after Dark II, from fundamental principles, as elegantly as possible and with the minimum of verbiage. This is a first principles account of the mathematical structure of modern theoretical physics, showing that it is not just a disparate bunch of algorithms and procedures, but is a unified structure based on observation, sound principles and solid logic, and allowing a unique physical interpretation in terms of fundamental constituents, or particles. Light after Dark III: The Mathematics of Gravity and Quanta explains essential mathematics at undergraduate level. Part I covers many core topics in a mathematics degree. Part II is a concise account of results in relativity, including the Lorentz transform from first principles, Riemann curvature, Einstein’s equation, derivations of the Schwarzschild and Friedmann solutions, and proofs of key results. Part III contains the mathematical foundations of relativistic quantum mechanics and constructs quantum electrodynamics. Divergence problems are treated with greater rigour than usual in theoretical physics, but without excessive formality. Classical electromagnetism is derived from fundamental principles. Part IV shows how quantum electrodynamics and general relativity can be described in a single structure. Light after Dark III: The Mathematics of Gravity and Quanta will interest students of mathematics and students of physics and philosophy with a mathematical leaning who are seeking a rigorous treatment and deeper mathematical insight into physical theory.

In this long awaited follow-up to the best-selling An Altar in the World, Barbara Brown Taylor explores ‘the treasures of darkness’ that the Bible speaks about. What can we learn about the ways of God when we cannot see the way ahead, are lost, alone, frightened, not in control or when the world around us seems to have descended into darkness?

Fifteen-year-old slacker Charlie Harker is stuck in the sleepy town of Rolling Hills for the summer, helping his mom renovate his great-grandfather's creaky old inn. It's not entirely dull, thanks to Charlie's new neighbor Miles Van Helsing, who insists there's paranormal activity happening in Rolling Hills. Charlie chalks it up to Miles being the town nutcase. But many townspeople are falling prey to a mysterious illness, and wisecracking Charlie quickly gets wise: there's something sinister going on in Rolling Hills.

A short, sleek novel of encounters set in the witching hours of Tokyo between midnight and dawn, and every bit as gripping as Haruki Murakami’s masterworks The Wind-Up Bird Chronicle and Kafka on the Shore. At its center are two sisters: Yuri, a fashion model sleeping her way into oblivion; and Mari, a young student soon led from solitary reading at an anonymous Denny’s into lives radically alien to her own: those of a jazz trombonist who claims they’ve met before; a burly female “love hotel” manager and her maidstaff; and a Chinese prostitute savagely brutalized by a businessman. These “night people” are haunted by secrets and needs that draw them together more powerfully than the differing circumstances that might keep them apart, and it soon becomes clear that Yuri’s slumber—mysteriously tied to the businessman plagued by the mark of his crime—will either restore or annihilate her. After Dark moves from mesmerizing drama to metaphysical speculation, interweaving time and space as well as memory and perspective into a seamless exploration of human agency—the interplay between self-expression and understanding, between the power of observation and the scope of compassion and love. Murakami’s trademark humor, psychological insight and grasp of spirit and morality are here distilled with an extraordinary, harmonious mastery.

Marie Brennan's Turning Darkness Into Light is a delightful fantasy of manners, the heir to the award-winning Natural History of Dragons series, a perfect stepping stone into an alternate Victorianesque fantasy landscape. "Overwhelmingly fun."—io9 on The Tropic of Serpents As the renowned granddaughter of Isabella Camherst (Lady Trent, of the riveting and daring Draconic adventure memoirs) Audrey Camherst has always known she, too, would want to make her scholarly mark upon a chosen field of study. When Lord Gleinheigh recruits Audrey to decipher a series of ancient tablets holding the secrets of the ancient Draconean civilization, she has no idea that her research will plunge her into an intricate conspiracy, one meant to incite rebellion and invoke war. Alongside dearest childhood friend and fellow archeologist Kudshayn, Audrey must find proof of the conspiracy before it’s too late.

NEW YORK TIMES BESTSELLER • “A meditation on sense-making when there’s no sense to be made, on letting go when we can’t hold on, and on being unafraid even when we’re terrified.”—Lucy Kalanithi “Belongs on the shelf alongside other terrific books about this difficult subject, like Paul Kalanithi’s When Breath Becomes Air and Atul Gawande’s Being Mortal.”—Bill Gates NAMED ONE OF THE BEST BOOKS OF THE YEAR BY REAL SIMPLE Kate Bowler is a professor at Duke Divinity School with a modest Christian upbringing, but she specializes in the study of the prosperity gospel, a creed that sees fortune as a blessing from God and misfortune as a mark of God’s disapproval. At thirty-five, everything in her life seems to point toward “blessing.” She is thriving in her job, married to her high school sweetheart, and loves life with her newborn son. Then she is diagnosed with stage IV colon cancer. The prospect of her own mortality forces Kate to realize that she has been tacitly subscribing to the prosperity gospel, living with the conviction that she can control the shape of her life with “a surge of determination.” Even as this type of Christianity celebrates the American can-do spirit, it implies that if you “can’t do” and succumb to illness or misfortune, you are a failure. Kate is very sick, and no amount of positive thinking will shrink her tumors. What does it mean to die, she wonders, in a society that insists everything happens for a reason? Kate is stripped of this certainty only to discover that without it, life is hard but beautiful in a way it never has been before. Frank and funny, dark and wise, Kate Bowler pulls the reader deeply into her life in an account she populates affectionately with a colorful, often hilarious retinue of friends, mega-church preachers, relatives, and doctors. Everything Happens for a Reason tells her story, offering up her irreverent, hard-won observations on dying and the ways it has taught her to live. Praise for Everything Happens for a Reason “I fell hard and fast for Kate Bowler. Her writing is naked, elegant, and gripping—she’s like a Christian Joan Didion. I left Kate’s story feeling more present, more grateful, and a hell of a lot less alone. And what else is art for?”—Glennon Doyle, #1 New York Times bestselling author of Love Warrior and president of Together Rising
