The Muslim thinker al-Ghazali (d. 1111) was one of the most influential theologians and philosophers of Islam and has been considered an authority in both Western and Islamic philosophical traditions. Born in northeastern Iran, he held the most prestigious academic post in Islamic theology in Baghdad, only to renounce the position and teach at small schools in the provinces for no money. His contributions to Islamic scholarship range from responding to the challenges of Aristotelian philosophy to creating a new type of Islamic mysticism and integrating both these traditions-falsafa and Sufism-into the Sunni mainstream. This book offers a comprehensive study of al-Ghazali's life and his understanding of cosmology-how God creates things and events in the world, how human acts relate to God's power, and how the universe is structured. Frank Griffel presents a serious revision of traditional views on al-Ghazali, showing that his most important achievement was the creation of a new rationalist theology in which he transformed the Aristotelian views of thinkers such as Avicenna to accord with intellectual currents that were well-established within Muslim theological discourse. Using the most authoritative sources, including reports from al-Ghazali's students, his contemporaries, and his own letters, Griffel reconstructs every stage in a turbulent career. The al-Ghazali that emerges offers many surprises, particularly on his motives for leaving Baghdad and the nature of his "seclusion" afterwards. Griffel demonstrates that al-Ghazali intended to create a new cosmology that moved away from concerns held earlier by Muslim theologians and Arab philosophers. This new theology aimed to provide a framework for the pursuit of the natural sciences and a basis for Islamic science and philosophy to flourish beyond the 12th century. Al-Ghazali's Philosophical Theology is the most thorough examination to date of this important thinker.
In recent decades, scholars have come to recognize the importance of classical Islamic philosophy both in its own right and in its preservation of and engagement with Western philosophical ideas. At the same time, the period immediately following the so-called classical period has often been seen as a sort of dark age, in which Islamic thought entered a long period of decline. In this monumental new work, Frank Griffel seeks to overturn this conventional wisdom, arguing that what he calls the "post-classical" period has been unjustly maligned and neglected by previous generations of scholars.The Formation of Post-Classical Philosophy in Islam is a comprehensive study of the far-reaching changes that led to a re-shaping of the philosophical discourse in Islam during the twelfth century. Earlier Western scholars thought that Islam's engagement with the tradition of Greek philosophy ended during that century. More recent analyses suggest that Islamic thinkers instead integrated Greek thought into the genre of rationalist Muslim theology (kalam). Griffel argues that even this view misses a key point. In addition to the integration of Greek ideas into kalam, Muslim theologians picked up the discourse of philosophy in Islam (falsafa) and began to produce books on philosophy. Books in these two genres, kalam and philosophy, argue for opposing teachings on the nature of God, the world's creation, and on the afterlife - even when written by the same authors. Griffel explains the emergence of a new genre of philosophical books called "hikma," works that stand opposed to Islamic theology and at the same wish to complement it. Offering a detailed history of philosophy in Iraq, Iran, and Central Asia during the twelfth century, together with an analysis of the way philosophy was practiced during this time, Griffel shows how works of falsafa, written by major Muslim theologians such as al-Ghazali developed step-by-step into critical assessments of philosophy that try to improve philosophical teachings, and eventually become fully fledged philosophical summas in the work of Fakhr al-Din al-Razi. Griffel's examination of the different methods of kalam and hikma demonstrate both the coherence and ambiguity of a Muslim post-classical philosopher's oeuvre.A work of extraordinary breadth and depth, The Formation of Post-Classical Philosophy in Islam will be essential reading for anyone interested in the history of Philosophy or the history of Islam.
The second volume of Islam and Rationality: The Impact of al-Ghazālī brings together twelve leading experts in the field of Ghazālī-studies who write about his thought and the influence he had on later Muslim thinkers.

Al-Ghazālī (d. 505/1111) is one of the most influential thinkers of Islam. There is hardly a genre of Islamic literature where he is not regarded as a major authority. Islamic Law, Sufism, ethics, philosophy, and theology are all deeply shaped by him. Yet in the past thirty years, the field of Ghazālī-studies has been shaken by the realization that Avicenna (Ibn Sīnā, d. 428/1037) and other philosophers had a strong influence on him. Now, after the 900th anniversary at his death, the field emerges stronger than ever. This second volume of Islam and Rationality: The Impact of al-Ghazālī brings together twelve leading experts on al-Ghazālī who write about his thought and the impact it had on later Muslim thinkers. Contributors are: Anna Ayşe Akasoy, Ahmed El Shamsy, Kenneth Garden, Frank Griffel, Jules Janssens, Damien Janos, Taneli Kukkonen, Stephen Ogden, M. Sait Özervarlı, Martin Riexinger, Ulrich Rudolph, and Ayman Shihadeh.

This interdisciplinary book covers the fundamentals of optical whispering gallery mode (WGM) microcavities, light–matter interaction, and biomolecular structure with a focus on applications in biosensing. Novel biosensors based on the hybridization of WGM microcavities and localized surface plasmon resonances (LSPRs) in metal nanoparticles have emerged as the most sensitive microsystem biodetection technology that boasts single molecule detection capability without the need for amplification and labeling of the analyte. The book provides an ample survey of the physical mechanisms of WGMs and LSPRs for detecting affinity, concentration, size, shape and orientation of biomarkers, while informing the reader about different classes of biomolecules, their optical properties and their importance in label-free clinical diagnostics. This expanded and updated second edition features a new chapter that introduces the reader to advanced in vivo biosensing techniques using WGM microcavities, looking at photothermal sensing, methods for trapping neutral atoms around WGM microcavities, and practical aspects of optoplasmonic sensing. The second Edition now provides a comprehensive introduction to the use of WGM microcavities in physical sensing which includes measurements with frequency combs, macro and micro (one atom) lasers, gyroscopes, optomechanical and parity-time-symmetric sensor devices. Chapter-end problems round out this comprehensive and fundamental textbook, inspiring a host of up-and-coming physicists, bioengineers, and medical professionals to make their own breakthroughs in this blossoming new field. This textbook can be used for both introductory and advanced courses about the modern optics of optical microcavities.
High frequencies of densely packed modern electronic equipment turn even the smallest piece of wire into a transmission line with signal retardation, dispersion, attenuation, and distortion. In electromagnetic environments with high-power microwave or ultra-wideband sources, transmission lines pick up noise currents generated by external electromagnetic fields. These are superimposed on essential signals, the lines acting not only as receiving antennas but radiating parts of the signal energy into the environment. This book is outstanding in its originality. While many textbooks rephrase that which has been written before, this book features: an accessible introduction to the fundamentals of electromagnetics; an explanation of the newest developments in transmission line theory, featuring the transmission line super theory developed by the authors; a unique exposition of the increasingly popular PEEC (partial element equivalent circuit) method, including recent research results. Both the Transmission Line Theory and the PEEC method are well suited to combine linear structures with circuit networks. For engineers, researchers, and graduate students, this text broadens insight into the basics of electrical engineering. It provides a deeper understanding of Maxwellian-circuit-like representations of multi-conductor transmission lines, justifies future research in this field.
