This book contains "...the ... largest collection of H. P. Lovecraft's fiction ever assembled," concentrating on the major phase of his career and including nearly all of his most famous work, and most of the "Cthulhu Mythos" stories.
The project is a collection of poems during a period of liberation and the beginning of a process called decolonizing my mind (bell hooks, Sisters in the Yam). As a southern belle from Bible Belt Louisiana that moved to the the Pacific Northwest during the 2016 Presidential elections and consistent waves of unarmed Black folk being killed by the police, I found myself at a place of honest reflection. This collection of poems captures my crisis of faith that was impacted by discovering and embracing my identity as a Black woman, the role that religious institutions play in perpetuating racism and other forms of oppression, the church's collective responses to my community members being murdered by the police in broad day light, and my own disappointment, realizations, and attempts at reconciling my spirituality with my identity in a way that would produce life for me personally. As a Black woman, the act of expression is both dangerous and sacred. I've rarely had the privacy and freedom that I had during this time and the transformation I experienced during this time has changed the trajectory of my life. Thus, this is a very meaningful project for me and I hope this contributes to the awareness of the diversity, beauty, art, pain, legacy, of Blackness in this country.
Melissa Marr, New York Times bestselling author of the Wicked Lovely series, returns to the ethereal and bloodthirsty world of faery in this dramatic story of the precarious space between two worlds—and the people who must thrive there. Lilywhite Abernathy is a criminal—she's half human, half fae, and since the time before she was born her very blood has been illegal. A war has been raging between humans and faeries, and the Queen of Blood and Rage, ruler of the fae courts, wants to avenge the tragic death of her heir due to the actions of reckless humans. Lily's father has always shielded her from the truth, but when she's sent to the prestigious St. Columba's school, she's delivered straight into the arms of a fae Sleeper cell—the Black Diamonds. The Diamonds are planted in the human world as the sons and daughters of the most influential families, and tasked with destroying it from within. Against her will, Lilywhite's been chosen to join them . . . and even the romantic attention of the fae rock singer Creed Morrison isn't enough to keep Lily from wanting to run back to the familiar world she knows. Don’t miss the lush, gripping follow-up, One Blood Ruby!

One of the most exciting predictions of Einstein's theory of gravitationisthat there may exist 'black holes': putative objects whose gravitational fields are so strong that no physical bodies and signals can break free of their pull and escape. Even though a completely reliable discovery of a black hole has not yet been made, several objects among those scrutinized by astrophysicists will very likely be conformed as black holes. The proof that they do exist, and an analysis of their properties, would have a significance going far beyond astrophysics. Indeed, what is involved is not just the discovery of yet another, even if extremely remarkable, astrophysical object, but a test of the correctness of our understanding the properties of space and time in extremely strong gravitational fields. Theoretical research into the properties of black holes and into the possible corollaries of the hypothesis that they exist, has been carried out with special vigor since the beginning of the 1970s. In addition to those specific features of black holes that are important for the interpretation of their possible astrophysical manifestations, the theory has revealed a nurober of unexpected characteristics of physical interactions involving black holes. By now, a fairly detailed understanding has been achieved of the properties of the black holes, their possible astrophysical manifestations, and the specifics of the various physical processes involved. Furthermore, profound links were found between black-hole theory and such seemingly very distant fields as thermodynamics, information theory, and quantum theory.
This introduction to the fascinating subject of black holes fills a significant gap in the literature which exists between popular, non-mathematical expositions and advanced textbooks at the research level. It is designed for advanced undergraduates and first year postgraduates as a useful stepping-stone to the advanced literature. The book provides an accessible introduction to the exact solutions of Einstein's vacuum field equations describing spherical and axisymmetric (rotating) black holes. The geometry and physical properties of these spacetimes are explored through the motion of particles and light. The use of different coordinate systems, maximal extensions and Penrose diagrams is explained. The association of the surface area of a black hole with its entropy is discussed and it is shown that with the introduction of quantum mechanics black holes cease to be black and can radiate. This result allows black holes to satisfy the laws of thermodynamics and thus be consistent with the rest of physics. In this new edition the problems in each chapter have been revised and solutions are provided. The text has been expanded to include new material on wormholes and clarify various other issues.
"I wrote this book because I love building robots. I want you to love building robots, too. It took me a while to learn about many of the tools and parts in amateur robotics. Perhaps by writing about my experiences, I can give you a head start."--David Cook Robot Building for Beginners, Third Edition provides basic, practical knowledge on getting started in amateur robotics. There is a mix of content: from serious reference tables and descriptions to personal stories and humorous bits. The robot described and built in this book is battery powered and about the size of a lunch box. It is autonomous; that is, it isn't remote controlled. The book is broken up into small chapters, suitable for bedtime (or bathroom) reading. The characteristics and purposes of each major component (resistor, transistor, wire, and motor) are described, followed by a hands-on experiment to demonstrate. Not only does this help the reader to understand a particular piece, but it also prepares them with processes to learn new parts on their own. An appendix offers an introduction to 3D printing and parts of the robot can, as an alternative, be "printed" using a 3D printer. The master project of the book is a simple, entertaining, line-following robot.
"Robot Building for Beginners" provides basic, practical knowledge on getting started in amateur robotics. Short chapters are perfectly suited for bedtime reading. It contains step-by-step instructions and small, hands-on experiments, including a line-following robot that the reader builds out of a sandwich container. By the end, the reader will make a palm-size solar robot and is also introduced to contests and potential project plans. Author David Cook begins with the anatomy of a homemade robot and advice on how to proceed successfully. General sources for tools and parts are provided in a consolidated listing and with specific part references throughout each chapter. Basic safety and numbering systems are also covered.
It is not an exaggeration to say that one of the most exciting predictions of Einstein's theory of gravitation is that there may exist "black holes": putative objects whose gravitational fields are so strong that no physical bodies or signals can break free of their pull and escape. The proof that black holes do exist, and an analysis of their properties, would have a significance going far beyond astrophysics. Indeed, what is involved is not just the discovery of yet another even if extremely remarkable, astro physical object, but a test of the correctness of our understanding of the properties of space and time in extremely strong gravitational fields. Theoretical research into the properties of black holes, and into the possible corol laries of the hypothesis that they exist, has been carried out with special vigor since the beginning of the 1970's. In addition to those specific features of black holes that are important for the interpretation of their possible astrophysical manifestations, the theory has revealed a number of unexpected characteristics of physical interactions involving black holes. By the middle of the 1980's a fairly detailed understanding had been achieved of the properties of the black holes, their possible astrophysical manifestations, and the specifics of the various physical processes involved. Even though a completely reliable detection of a black hole had not yet been made at that time, several objects among those scrutinized by astrophysicists were considered as strong candidates to be confirmed as being black holes.
