3 Rays


Book Description

'3 Rays is like exploring the Mother Earth, and finding the rare treasures'-Gulzar, poet, lyricist and film-maker 'Satyajit Ray's work is like a beautiful scene from nature, and that's the reason we get lost in his beautiful art' -Shoojit Sircar, film-maker 'Ray's magic, the simple poetry of his images and their emotional impact, will always stay with me'-Martin Scorsese, film director, producer, screenwriter and actor 'Satyajit Ray's artifice and honesty set him apart from other film directors'-The Guardian 'Satyajit Ray's world of restless watchfulness and nuance'-The New York Times 'The quiet but deep observation ... have impressed me greatly'-Akira Kurosawa, film-maker The most anticipated book on the centenary birth anniversary of Satyajit Ray An amazingly brilliant collection of Satyajit Ray's previously unpublished autobiographical writings, illustrations, fictions and non-fictions A collector's item, 3 Rays is a source of delight for every reader Satyajit Ray (1921-1992), through his life, philosophy and works offered a unique aesthetic sensibility, which took Indian cinema, art and literature to a new height. An ace designer, music composer, illustrator and a gifted writer, Ray gave us the awe-inspiring sleuth Feluda, and the maverick scientist, Professor Shonku-two iconic characters loved and revered by millions of readers. On the occasion of his centenary birth anniversary, 3 Rays: Stories from Satyajit Ray, the first book in The Penguin Ray Library series, opens a window to the brilliance of this Renaissance man. With more than forty stories and poems along with many unpublished works, autobiographical writings and illustrations by Ray, this volume offers a unique glimpse into Ray's creative genius.




The Three Rays of Witchcraft


Book Description

Inspired by a Vision of Awen depicting a spear, a flowering branch, and a horned serpent emanating from three drops of wisdom, surrounded by three worlds, Christopher Penczak received a teaching to reconcile many disparate parts of modern Witchcraft into a cohesive body of magickal lore for personal evolution and enlightenment. Experimented with and expanded upon, this lore is now shared through his book The Three Rays of Witchcra : Power, Love and Wisdom in the Garden of the Gods. Striving to weave the diverse threads of his personal practice together, the Three Rays provided Christopher with a powerful framework to bring together modern Wicca, Traditional Craft, Druidism, Theosophy, Qabalah, Shamanism, and alternative health into a greater whole. The text outlines a model of the universe based upon the forces of Power, Love, and Wisdom. Associated with each is a ray, a path we can travel spiritually and evoke energetically. Known as the Straight Line, the Bent Line and the Crooked Line, each offers different magick, knowledge and mysteries. Each ray is associated with a race of spiritual entities with whom we can partner, including the angels, faeries, animal powers and ancestors. ..". an offering full of angels and fairies, gods and humans, diverse yet connected and each with their own powers and wisdom." - Sorita Este, author of Hekate Liminal Rites, Practical Planetary Magick, and The Guises of the Morriga"




Waves And Rays In Elastic Continua (3rd Edition)


Book Description

The present book — which is the third, significantly revised edition of the textbook originally published by Elsevier Science — emphasizes the interdependence of mathematical formulation and physical meaning in the description of seismic phenomena. Herein, we use aspects of continuum mechanics, wave theory and ray theory to explain phenomena resulting from the propagation of seismic waves.The book is divided into three main sections: Elastic Continua, Waves and Rays and Variational Formulation of Rays. There is also a fourth part, which consists of appendices.In Elastic Continua, we use continuum mechanics to describe the material through which seismic waves propagate, and to formulate a system of equations to study the behaviour of such a material. In Waves and Rays, we use these equations to identify the types of body waves propagating in elastic continua as well as to express their velocities and displacements in terms of the properties of these continua. To solve the equations of motion in anisotropic inhomogeneous continua, we invoke the concept of a ray. In Variational Formulation of Rays, we show that, in elastic continua, a ray is tantamount to a trajectory along which a seismic signal propagates in accordance with the variational principle of stationary traveltime. Consequently, many seismic problems in elastic continua can be conveniently formulated and solved using the calculus of variations. In the Appendices, we describe two mathematical concepts that are used in the book; namely, homogeneity of a function and Legendre's transformation. This section also contains a list of symbols.




Waves And Rays In Seismology: Answers To Unasked Questions (Third Edition)


Book Description

This is a book on seismology dealing with advanced aspects of wave propagation in complex media. It can also be viewed as a book on mathematical modelling, wherein the accuracy of describing seismic phenomena exemplifies the modelling itself. The book gives an insight into the power of abstractness by applying the same mathematical methods and strategies to solve a variety of different physical problems. This book covers a broad range of topics in an advanced yet accessible manner. Each chapter is accompanied by a number of solved exercises, which render the book convenient for a lecturer and facilitate its use for an independent study. The details of mathematical methods are discussed in the appendices, which form a substantial portion of the book.

Combinatorial Algebraic Geometry


Book Description

This volume consolidates selected articles from the 2016 Apprenticeship Program at the Fields Institute, part of the larger program on Combinatorial Algebraic Geometry that ran from July through December of 2016. Written primarily by junior mathematicians, the articles cover a range of topics in combinatorial algebraic geometry including curves, surfaces, Grassmannians, convexity, abelian varieties, and moduli spaces. This book bridges the gap between graduate courses and cutting-edge research by connecting historical sources, computation, explicit examples, and new results.
