The only child of Muhammad to survive him, Fatima was from early times taken up by Shî'a Islam, for whose adherents she is the virgin mother, the heavenly intercessor with untold power before God's throne, and the grieving mother of al-Husayn, the Shi'a's most important martyr. During her life she was impoverished and weak, neglected, marginalized, and divested of justice: but her reward in heaven comprises incalculable riches, all those in heaven will bow their heads to her, and her company will be the angels and the friends of God. Here, for the first time, her story is told.
When, on an autumn Medina night in 61/680, the night that saw al-òHusayn killed, Umm Salama was torn from her sleep by an apparition of a long-dead Muòhammad, she slipped effortlessly into a progression of her co-religionists who, irrespective of status, gender or standing with God, were the recipients of dark and arresting visions. At the core of those Delphian dreams, peopled by angels or æginn or esteemed forbears and textured with Iraqi dust and martyrs' blood, was the Karbalåa' event. Her dream would be recounted by an array of Muslim scholars, from al-Tirmiödåi, stellar pupil of al-Buùhåaråi, and Ibn 'Asåakir, untiring chronicler of Syrian history, to bibliophile theologian Ibn òTåa åus and Egyptian polymath al-Suyåuòtåi. But this was not Umm Salama's only otherworldly encounter and she was not the only one to have al-òHusayn's fate disturb her nights. This is their story"--
The Annual International Conference on Shi‘i Studies is organised by the Research and Publications Department of The Islamic College, London. The conference aims to provide a broad platform for scholars working in the field of Shi‘i Studies to present their latest research and to explore diverse opinions on Shi‘i thought, practice, and heritage. This book comprises a selection of papers from the fourth conference held on 5-6 May 2018.

Provides the basics of spacecraft orbital dynamics plus attitude dynamics and control, using vectrix notation Spacecraft Dynamics and Control: An Introduction presents the fundamentals of classical control in the context of spacecraft attitude control. This approach is particularly beneficial for the training of students in both of the subjects of classical control as well as its application to spacecraft attitude control. By using a physical system (a spacecraft) that the reader can visualize (rather than arbitrary transfer functions), it is easier to grasp the motivation for why topics in control theory are important, as well as the theory behind them. The entire treatment of both orbital and attitude dynamics makes use of vectrix notation, which is a tool that allows the user to write down any vector equation of motion without consideration of a reference frame. This is particularly suited to the treatment of multiple reference frames. Vectrix notation also makes a very clear distinction between a physical vector and its coordinate representation in a reference frame. This is very important in spacecraft dynamics and control problems, where often multiple coordinate representations are used (in different reference frames) for the same physical vector. Provides an accessible, practical aid for teaching and self-study with a layout enabling a fundamental understanding of the subject Fills a gap in the existing literature by providing an analytical toolbox offering the reader a lasting, rigorous methodology for approaching vector mechanics, a key element vital to new graduates and practicing engineers alike Delivers an outstanding resource for aerospace engineering students, and all those involved in the technical aspects of design and engineering in the space sector Contains numerous illustrations to accompany the written text. Problems are included to apply and extend the material in each chapter Essential reading for graduate level aerospace engineering students, aerospace professionals, researchers and engineers.
