Daoist Nei Gong: The Philosophical Art of Change


Damo Mitchell - 2011
    Based upon the original teachings of the great sage Laozi, it has only ever been taught to close students of the masters chosen as the heads of the ancient orders.This book provides a breakdown of the entire Nei Gong process, and explains in plain English the philosophy which underpins Nei Gong practice, and which is based on the original teachings of the ancient Daoist priests. The methodology of Sung breathing, an advanced meditative practice which has until now been reserved for 'inner-door' students is described, and the book contains an entire set of Qigong exercises accompanied by instructional photographs and drawings.This book will be of interest to all practitioners of Qi Gong, martial arts and meditation, and will be a rewarding read for anyone interested in Eastern philosophy.

Learning Chinese Characters


Alison Matthews - 2007
    This otherwise daunting task is made easier by the use of techniques based on the psychology of leaning and memory. key principles include the use of visual imagery, the visualization of short "stories," and the systematic building up of more complicated characters from basic building blocks.Although Learning Chinese Characters is primarily a book for serious learners of Mandarin Chinese, it can be used by anyone with an interest in Chinese characters, without any prior knowledge of Chinese. It can be used alongside (or after, or even before) a course in the Chinese language. All characters are simplified (as in mainland China) but traditional characters are also given, when available.Key features:-Specially designed pictures and stories are used in a structured way to make the learning process more enjoyable and effective, reducing the need for rote learning to the absolute minimum.-The emphasis throughout is on learning and remembering the meanings and pronunciations of the characters. Tips are also included on learning techniques and how to avoid common problems.-Characters are introduced in a logical sequence, which also gives priority to learning the most common characters first.-Modern simplified characters are used, with pronunciations given in pinyin. Key information is given for each character, including radical, stroke—count, traditional form, compounds, and guidance on writing the character.This is a practical guide with a clear, concise and appealing layout, and it is well—indexed with easy look—up methods. The 800 Chinese characters and 1,033 compounds specified for the original HSK Level A proficiency test are covered.

A Most Incomprehensible Thing: Notes Towards a Very Gentle Introduction to the Mathematics of Relativity


Peter Collier - 2012
    This user-friendly self-study guide is aimed at the general reader who is motivated to tackle that not insignificant challenge. The book is written using straightforward and accessible language, with clear derivations and explanations as well as numerous fully solved problems. For those with minimal mathematical background, the first chapter provides a crash course in foundation mathematics. The reader is then taken gently by the hand and guided through a wide range of fundamental topics, including Newtonian mechanics; the Lorentz transformations; tensor calculus; the Einstein field equations; the Schwarzschild solution (which gives a good approximation of the spacetime of our Solar System); simple black holes and relativistic cosmology. Following the historic 2015 LIGO (Laser Interferometer Gravitational-Wave Observatory) detection, there is now an additional chapter on gravitational waves, ripples in the fabric of spacetime that potentially provide a revolutionary new way to study the universe. Special relativity helps explain a huge range of non-gravitational physical phenomena and has some strangely counter-intuitive consequences. These include time dilation, length contraction, the relativity of simultaneity, mass-energy equivalence and an absolute speed limit. General relativity, the leading theory of gravity, is at the heart of our understanding of cosmology and black holes.Understand even the basics of Einstein's amazing theory and the world will never seem the same again.
