The Genera of Orchidaceae in Hong Kong is a handy reference for both amateurs and professional botanists in Asia who wish to enter the field of modern orchidology. Orchid appreciation is an art deeply rooted in Asian cultures. But in 1977, when this book was first published, orchidology as a science was new to people there. The technical vocabulary was unfamiliar and the subject matter difficult to understand. Therefore, this volume was intended as a general, easy-to-use reference book, with illustrations of the basic structure of orchids and their habit and habitat clearly described in Chapter I. The book may also be used as a self-help guide for naturalists and gardeners in Hong Kong who wish to identify an orchid new to them. In Chapter II, keys, descriptions, and illustrations are given to allow the reader to look up and gain information about individual orchid species. Chapter III provides an analysis of the composition and an interpretation of the phytogeographic significance of the Orchidaceae in Hong Kong. Finally, Chapter IV helps the reader to understand and remember the Latinized names of orchids by providing an explanation on the origin and meaning of the generic names. This book is a facsimile reprint of the 1977 edition, which was published at a time when no comprehensive account of the genera of the orchids of Hong Kong had ever been attempted. Even after many decades, this volume remains the essential reference on orchid species growing in Hong Kong. This commemorative edition features a new foreword and a chronology of Professor Hu's major life events.

With the development of science and technology,more and more complex materials such as porous materials, ion liquid, liquid crystals, thin ?lms and colloids etc. are being developed in laboratories. However, it is dif?cult to prepare these advanced materials and use them on a large scale without some experience. Therefore, mo- cular thermodynamics, a method that laid emphasis on correlating and interpreting the thermodynamic properties of a variety of ?uids in the past, has been recently employed to study the equilibrium properties of complex materials and establish thermodynamic models to analyse the evolution process of their components, - crostructures and functions during the preparation process. In this volume, some important progress in this ?eld, from fundamental aspects to practical applications, is reviewed. In the ?rst chapter of this volume, Prof. Jianzhong Wu presents the application of Density Functional theory (DFT) for the study of the structure and thermodynamic properties of both bulk and inhomogeneous ?uids. This chapter presents a tut- ial overview of the basic concepts of DFT for classical systems, the mathematical relations linking the microstructure and correlation functions to measurable th- modynamic quantities, and the connections of DFT with conventional liquid-state theories. While for pedagogythe discussion is limited to one-componentsimple - ids, similar ideas and concepts are directly applicable to mixtures and polymeric systems of practical concern. This chapter also covers a few theoretical approaches to formulate the thermodynamic functional.

This volume develops new strategies for reading, contextualizing, and interpreting the long Chinese tradition of women's biography. Drawing upon a vast array of sources - from formal biography to poetry, letters, and oral interviews - the authors examine how women's biography served particular cultural, political, and world-making projects, and how it illuminates these projects in new ways by highlighting tensions within and between them.

This textbook highlights a concise introduction to quantum mechanics in a readable and serious manner. Being readable, the book intends to present the beauty and magic of quantum mechanics to the mass public. Being serious, the book uses mathematics to describe the most profound results in quantum mechanics. To balance the two, the book assumes that the readers are familiar with high-school mathematics and instructs the least possible advanced mathematics necessary for the understanding of quantum mechanics. The book first covers the history of quantum mechanics and then introduces the magical quantum world, including quantum states living in Hilbert space, indistinguishable particles, linear superposition, Heisenberg's uncertainty relations, quantum entanglement, Bell's inequality, quantum energy levels, Schroedinger's cat and many-worlds theory, etc. To compare with classic physics, the book also covers the classic mechanics before introducing quantum mechanics. At last, the book briefly covers quantum computing and quantum communications. Besides readers of other majors, the book is also a good reference for students in physics. It helps physics students to develop a solid understanding of the basics of quantum mechanics, preventing them from getting lost in solving the Schroedinger equation. The book also discusses quantum entanglement and quantum information which traditional quantum mechanics textbooks do not cover. The Foreword is written by Frank Wilczek, Nobel Laureate in physics, 2004. This book is a translation of an original German edition. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation.

"Autumn wind, autumn rain, fill my heart with sorrow"-these were the last words of Qiu Jin (1875-1907), written before she was beheaded for plotting to overthrow the Qing empire. Eventually, she would be celebrated as a Republican martyr and China's first feminist, her last words committed to memory by schoolchildren. Yet during her lifetime she was often seen as eccentric, even deviant; in her death, and still more in the forced abandonment of her remains, the authorities had wanted her to disappear into historical oblivion. Burying Autumn tells the story of the enduring friendship between Qiu Jin and her sworn-sisters Wu Zhiying and Xu Zihua, who braved political persecution to give her a proper burial. Formed amidst social upheaval, their bond found its most poignant expression in Wu and Xu's mourning for Qiu. The archives of this friendship-letters, poems, biographical sketches, steles, and hand-copied sutra-vividly display how these women understood the concrete experiences of modernity, how they articulated those experiences through traditional art forms, and how their artworks transformed the cultural traditions they invoked even while maintaining deep cultural roots. In enabling Qiu Jin to acquire historical significance, their friendship fulfilled its ultimate socially transformative potential.
