A new translation of the primary Indian Buddhist text on buddha nature, with Tibetan commentaries explaining how this text can be used to contemplate and realize one's own buddha nature. "Buddha nature" (tathāgatagarbha) is the innate potential in all living beings to become a fully awakened buddha. This book discusses a wide range of topics connected with the notion of buddha nature as presented in Indo-Tibetan Buddhism and includes an overview of the sūtra sources of the tathāgatagarbha teachings and the different ways of explaining the meaning of this term. It includes new translations of the Maitreya treatise Mahāyānottaratantra (Ratnagotravibhāga), the primary Indian text on the subject, its Indian commentaries, and two (hitherto untranslated) commentaries from the Tibetan Kagyü tradition. Most important, the translator’s introduction investigates in detail the meditative tradition of using the Mahāyānottaratantra as a basis for Mahāmudrā instructions and the Shentong approach. This is supplemented by translations of a number of short Tibetan meditation manuals from the Kadampa, Kagyü, and Jonang schools that use the Mahāyānottaratantra as a work to contemplate and realize one’s own buddha nature.

Super VC-10 G-ASGC, now preserved at Duxford Air Museum, hurtled across the North Atlantic at a speed that was just below the maximum the aircraft was allowed. The Flight Engineer was in his element and spent the night fine-tuning the engines to keep the speed spot on. After a short time the Chief Steward came onto the flight deck and announced that the dinner service was complete and that the passengers were now all bedded down for the night. "I am sorry to spoil your rest break but we will be landing in just over two hours," I said. "What are we flying? A bloody Concorde or something! I will have to wake them up for a full English breakfast in one hour," he replied. "Scrub the breakfast and give them champagne for landing," was my response. We landed at Prestwick on the Scottish west coast after just five hours and one minute from take-off at JFK. The scheduled time was six hours and twenty minutes so this was some achievement and to this day has never been beaten by a scheduled aircraft.

A Mother's Prayer, a Son's Goodbye, and a Song that Moved the World

This book advances understanding of cloud microphysics and provides a unified theoretical foundation for modeling cloud processes, for researchers and advanced students.

This book aims to promote the understanding of some of the basic mathematical and scientific issues in the subjects relating to climate dynamics, chaos and quantum mechanics. It is based on substantial research work in atmospheric science carried out over twenty years. Atmospheric flows exhibit self similar fractal fluctuations, a signature of long-range correlations on all space-time scales. Realistic simulation and prediction of atmospheric flows requires the incorporation of the physics of observed fractal fluctuation characteristics in traditional meteorological theory. A general systems theory model for fractal space-time fluctuations in turbulent atmospheric flows is presented and applied to the formation of rain in warm clouds. This model gives scale-free universal governing equations for cloud growth processes. The model predicted cloud parameters are in agreement with reported observations, in particular, the cloud drop-size distribution. Rain formation can occur in warm clouds within 30 minutes as observed in practice under favourable conditions of moisture supply in the environment. Traditional cloud physical concepts for rain development requires over an hour for a full-sized raindrop to form. The book provides background reading for postgraduate students of Meteorology, Atmospheric Sciences/Physics, Environmental Sciences, and scientists working in the field of the topic of the book as well as the multidisciplinary field of Nonlinear Dynamics and Chaos.

Cloud research is a rapidly developing branch of climate science that's vital to climate modelling. With new observational and simulation technologies our knowledge of clouds and their role in the warming climate is accelerating. This book provides a comprehensive overview of research on clouds and their role in our present and future climate, covering theoretical, observational, and modelling perspectives. Part I discusses clouds from three different perspectives: as particles, light and fluid. Part II describes our capability to model clouds, ranging from theoretical conceptual models to applied parameterised representations. Part III describes the interaction of clouds with the large-scale circulation in the tropics, mid-latitudes, and polar regions. Part IV describes how clouds are perturbed by aerosols, the land-surface, and global warming. Each chapter contains end-of-chapter exercises and further reading sections, making this an ideal resource for advanced students and researchers in climatology, atmospheric science, meteorology, and climate change.

An Introduction to Clouds provides a fundamental understanding of clouds, ranging from cloud microphysics to the large-scale impacts of clouds on climate. On the microscale, phase changes and ice nucleation are covered comprehensively, including aerosol particles and thermodynamics relevant for the formation of clouds and precipitation. At larger scales, cloud dynamics, mid-latitude storms and tropical cyclones are discussed leading to the role of clouds on the hydrological cycle and climate. Each chapter ends with problem sets and multiple-choice questions that can be completed online, and important equations are highlighted in boxes for ease of reference. Combining mathematical formulations with qualitative explanations of underlying concepts, this accessible book requires relatively little previous knowledge, making it ideal for advanced undergraduate and graduate students in atmospheric science, environmental sciences and related disciplines.
