Sommario/riassunto

Create physically realistic 3D Graphics environments with this introduction to the ideas and techniques behind the process. Author David H. Eberly includes simulations to introduce the key problems involved and then gradually reveals the mathematical and physical concepts needed to solve them. He then describes all the algorithmic foundations and uses code examples and working source code to show how they are implemented, culminating in a large collection of physical simulations. The book tackles the complex, challenging issues that other books avoid, including Lagrangian dynamics, rigid body dynamics, impulse methods, resting contact, linear complementarity problems, deformable bodies, mass-spring systems, friction, numerical solution of differential equations, numerical stability and its relationship to physical stability, and Verlet integration methods. This book even describes when real physics isn't necessary - and hacked physics will do.

Sommario/riassunto

With the discovery of RNAi pathways and the histone code, epigenetics has become a popular and fast evolving research topic. Plant science has made a number of elementary contributions to this field, and the common elements of epigenetic systems have linked research groups interested in plant, fungal and animal systems.This volume provides a comprehensive overview epigenetic mechanisms and biological



processes in plants, illustrating the wider relevance of this research to work in other plant science areas and on non-plant systems. It discusses recent advances in our knowledge

Sommario/riassunto

Chronicling the people, places, and events of the state's colorful history, Colorado: The Highest State is the story of how Colorado grew



up. Through booms and busts in farming and ranching, mining and railroading, and water and oil, Colorado's past is a cycle of ups and downs as high as the state's peaks and as low as its canyons. The second edition is the result of a major revision, with updates on all material, two new chapters, and ninety new photos.  Each chapter is followed by questions, suggested activities, recommended reading, a ""Did you know?"" trivia section, and recommended web
