This book provides a modern pedagogical exposition of the mechanical approach to statistical mechanics initiated by Boltzmann with his early works (1866–1871). Despite the later contribution by Helmholtz, Boltzmann himself (1884–1887), Gibbs, P. Hertz, and Einstein, the mechanical approach remained almost unknown to the modern reader, in favour of the celebrated combinatorial approach, developed by Boltzmann himself during his probabilistic turn (1876–1884). The brief constitutes an ideal continuation of a graduate course of classical mechanics and requires knowledge of basic calculus in many dimensions (including differential forms), thermodynamics, and probability theory, besides Hamiltonian mechanics. The cornerstone of the whole presentation is the ergodic hypothesis. Special attention is devoted to Massieu potentials (the Legendre transforms of the entropy) which are most natural in statistical mechanics and also allow for a more direct treatment of the topic of ensemble equivalence. In this second edition, a chapter is added that addresses the long-debated question of how the second law of thermodynamics can be reconciled with mechanics, by using modern methods of non-equilibrium statistical mechanics.

This book explores the profound challenges faced by couples embarking on fertility journeys. This transformative experience can often feel demanding and complex, as each person becomes intensely focused on the quest for procreation, potentially losing sight of their own individuality. Alongside this struggle, issues related to sexual function may arise, leading to conflicts within the partnership, mood disorders, and even the development of addictive behaviors such as overeating or engagement with pornography.

Written by internationally renowned experts, the 4th edition of this book provides detailed practical guidance and advice on the diagnosis and management of the complete range of ocular cancers. Supplying the reader with state-of-the-art knowledge required in order to identify these cancers early and to treat them as effectively as possible, this book is divided into seven volumes: Basic Principles, Conjunctival Tumors, Orbital Tumors, Uveal Tumors, Retinal Tumors, Retinoblastoma, and Eyelid Tumors. The information presented enables readers to provide effective patient care using the latest knowledge on ophthalmic oncology and to verify diagnostic conclusions based on comparison with numerous full-color clinical photographs from the authors' private collections, histopathologic microphotographs, imaging studies, and crisp illustrations.
