Based around a theme of the construction of a game engine, this textbook is for final year undergraduate and graduate students, emphasising formal methods in writing robust code quickly. This book takes an unusual, engineering-inspired approach to illuminate the creation and verification of large software systems. Where other textbooks discuss business practices through generic project management techniques or detailed rigid logic systems, this book examines the interaction between code in a physical machine and the logic applied in creating the software. These elements create an informal and rigorous study of logic, algebra, and geometry through software. Assuming prior experience with C, C++, or Java programming languages, chapters introduce UML, OCL, and Z from scratch. Extensive worked examples motivate readers to learn the languages through the technical side of software science.

What is it like to grow up with a sibling on the autism spectrum? What kind of relationship do such siblings have? How does that relationship change as the siblings get older? In this moving collection of beautifully-written personal accounts, siblings from a variety of backgrounds, and in different circumstances, share their experiences of growing up with a brother or sister with autism. Despite their many differences, their stories show that certain things are common to the "sibling experience": the emotional terrain of looking on or being overlooked; the confusion of accommodating resentment, love, and helplessness; and above all the yearning to connect across neurological difference. Siblings and Autism is a thought-provoking book that will appeal to anyone with a personal or professional interest in autism, including parents of siblings of children on the spectrum, teachers, counsellors, and psychologists.

Prominent author and abolitionist Lydia Maria Child began writing her ""letters"" from New York in August 1841 as a response to the troubling realities marking her private and public life. In particular, she was preoccupied by her editorial duties at the National Anti-Slavery Standard and dismayed by the growing sectarian spirit of anti-slavery reform. Collected primarily from the pages of the Standard, her literary essays on women's rights, the preaching of African American minister Julia Pell, the Crosby Street Synagogue, animal magnetism, the engineering miracle of Croton Aqueduct, and countless other people, topics, and events capture the breathless and sometimes unsettling transformation of one representative hub of national life. In his general introduction and annotation of the text, Bruce Mills reconstructs the biographical and cultural context surrounding the book's publication and documents substantive changes to the Standard's version of the letters and the book form. This edition also includes ten letters that Child chose to omit from earlier editions, including essays on the farewell gathering for the Amistad captives at the African Methodist Episcopal Zion Church and the near lynching of British abolitionist George Thompson. Long considered among Child's best writing, Letters from New-York still captivates readers with its moving descriptions of enduring cultural realities. It offers us a telling glimpse of New York as an emerging urban center and is an invaluable addition to the library of American literature.
