Ties That Tether


Book Description

One of Betches' 7 Books by Black Authors You Need to Read This Summer One of Elite Daily’s Books Featuring Interracial Relationships You Should Read In 2020 One of Marie Claire’s 2020 Books You Should Add to Your Reading List When a Nigerian woman falls for a man she knows will break her mother’s heart, she must choose between love and her family. At twelve years old, Azere promised her dying father she would marry a Nigerian man and preserve her culture, even after immigrating to Canada. Her mother has been vigilant about helping—well forcing—her to stay within the Nigerian dating pool ever since. But when another match-made-by-mom goes wrong, Azere ends up at a bar, enjoying the company and later sharing the bed of Rafael Castellano, a man who is tall, handsome, and…white. When their one-night stand unexpectedly evolves into something serious, Azere is caught between her feelings for Rafael and the compulsive need to please her mother. Soon, Azere can't help wondering if loving Rafael makes her any less of a Nigerian. Can she be with him without compromising her identity? The answer will either cause Azere to be audacious and fight for her happiness or continue as the compliant daughter.







All the Fierce Tethers


Book Description

Readers familiar with Lia Purpura’s highly praised essay collections—Becoming, On Looking, and Rough Likeness—will know she’s a master of observation, a writer obsessed with the interplay between humans and the things they see. The subject matter of All the Fierce Tethers is wonderfully varied, both low (muskrats, slugs, a stained quilt in a motel room) and lofty (shadows, prayer, the idea of beauty). In “Treatise Against Irony,” she counters this all-too modern affliction with ferocious optimism and intelligence: “The opposite of irony is nakedness.” In “My Eagles,” our nation’s symbol is viewed from all angles—nesting, flying, politicized, preserved. The essay in itself could be a small anthology. And, in a fresh move, Purpura turns to her own, racially divided Baltimore neighborhood, where a blood stain appears on a street separating East (with its Value Village) and West (with its community garden). Finalist for the National Book Critics Award, winner of the Pushcart Prize, Lia Purpura returns with a collection both sustaining and challenging.




Space Tethers and Space Elevators


Book Description

Michel van Pelt explains for the first time the principle of space tethers: what they are and how they can be used in space. He introduces non-technical space enthusiasts to the various possibilities and feasibility of space tethers including the technological challenges and potential benefits. He illustrates how, because of their inherent simplicity, space tethers have the potential to make space travel much cheaper, while ongoing advances in tether material technology may make even seemingly far-fetched ideas a reality in the not too distant future.

Theory and Applications of Multi-Tethers in Space


Book Description

This book offers a comprehensive overview of recently developed space multi-tethers, such as maneuverable space tethered nets and space tethered formation. For each application, it provides detailed derivatives to describe and analyze the mathematical model of the system, and then discusses the design and proof of different control schemes for various problems. The dynamics modeling presented is based on Newton and Lagrangian mechanics, and the book also introduces Hamilton mechanics and Poincaré surface of section for dynamics analysis, and employs both centralized and distributed controllers to derive the formation question of the multi-tethered system. In addition to the equations and text, it includes 3D design drawings, schematic diagrams, control scheme blocks and tables to make it easy to understand. This book is intended for researchers and graduate students in the fields of astronautics, control science, and engineering.
