Galaxies, along with their underlying dark matter halos, constitute the building blocks of structure in the Universe. Of all fundamental forces, gravity is the dominant one that drives the evolution of structures from small density seeds at early times to the galaxies we see today. The interactions among myriads of stars, or dark matter particles, in a gravitating structure produce a system with fascinating connotations to thermodynamics, with some analogies and some fundamental differences.

Ignacio Ferreras presents a concise introduction to extragalactic astrophysics, with emphasis on stellar dynamics, and the growth of density fluctuations in an expanding Universe. Additional chapters are devoted to smaller systems (stellar clusters) and larger ones (galaxy clusters). Fundamentals of Galaxy Dynamics, Formation and Evolution is written for advanced undergraduates and beginning postgraduate students, providing a useful tool to get up to speed in a starting research career. Some of the derivations for the most important results are presented in detail to enable students appreciate the beauty of maths as a tool to understand the workings of galaxies. Each chapter includes a set of problems to help the student advance with the material.

Architecture and Fire develops a conceptual reassessment of architectural conservation through the study of the intimate relationship between architecture and fire. Stamatis Zografos expands on the general agreement among many theorists that the primitive hut was erected around fire – locating fire as the first memory of architecture, at the very beginning of architectural evolution.

Following the introduction, Zografos analyses the archive and the renewed interest in the study of archives through the psychoanalysis of Jacques Derrida. He moves on to explore the ambivalent nature of fire, employing the conflicting philosophies of Gaston Bachelard and Henri Bergson to do so, before discussing architectural conservation and the relationship between listed buildings, the function of archives, and the preservation of memories from the past. The following chapter investigates how architecture evolves by absorbing and accommodating fire, while the penultimate chapter examines the critical moment of architectural evolution: the destruction of buildings by fire, with a focus on the tragic disaster at London’s Grenfell Tower in 2017. Zografos concludes with thoughts on Freud’s drive theory. He argues the practice of architectural conservation is an expression of the life drive and a simultaneous repression of the death drive, which suggests controlled destruction should be an integral part of the conservation agenda.

Architecture and Fire is founded in new interdisciplinary research navigating across the boundaries of architecture, conservation, archival theory, classical mythology, evolutionary theory, thermodynamics, philosophy and psychoanalysis. It will be of interest to readers working in and around these disciplines.
