This book illustrates the role of randomness and noise in living organisms. Traditionally, the randomness and noise have been used in understanding signal processing in communications. This book is divided into two sections, the first of which introduces readers to the various types and sources of noise and the constructive role of noise in non-linear dynamics. It also analyses the importance of randomness and noise in a variety of science and engineering applications. In turn, the second section discusses in detail the functional role of noise in biological processes for example, in case of brain function at the level of ion channel, synaptic level and even at cognitive level. These are described in various chapters. One of the challenging issue finding the neuronal correlates of various meditative states is to understand how brain controls various types of noise so as to reach a state of synchronized oscillatory state of the brain corresponding to the state of Samadhi. This is described in details in one chapter called Noise, Coherence and meditation. The concept of noise and the role of randomness in living organism raise lot of controversy for last few decades. This is discussed in a separate chapter. Finally, the epistemic and ontic nature of randomness as discussed in physical science are investigated in the context of living organism.

According to this framework, epistemological issues related to decision making and state of mind are seen to be similar to issues related to equanimity and neutral mind, as discussed in Buddhist perspective.

Book DescriptionDemystifying the Akasha:Consciousness and the Quantum VacuumDuality, including the spiritual/material and mind/body dichotomies,has been the basis of the Western paradigm for four hundred years, andhas been blamed for major world problems. Meanwhile, in the East, nonduality has prevailed. While science isgenerally seen in opposition to nonduality, this book sets out to provethe compatibility of the scientifi c outlook and the spiritualnonduality of India by constructing a mathematical model of cosmicconsciousness. The ideas and their history are presented nontechnically in Part One, while the full mathematical details arepresented in Part Two.Ralph Abraham is Professor of Mathematics at the University ofCalifornia at Santa Cruz, one of the pioneers of chaos theory. He isthe author or coauthor of several math texts, including Foundations of Mechanics,Dynamics the Geometry of Behavior, and Chaos in Discrete DynamicalSystems. He has also written books on the history of math,philosophy, and the arts, such as Chaos, Creativity, and CosmicConsciousness and The Evolutionary Mind.Sisir Roy is Professor of Theoretical Physics, Indian StatisticalInstitute, Kolkata. His field of interest covers foundations of quantummechanics, cosmology, functional geometry and brain function. He haspublished more than 100 papers in peer reviewed international journalsand nine research and edited monographs by Kluwer Academic,WorldScientific etc. publishers.Praisefor Demystifying the Akasha: Consciousness and the Quantum Vacuum"A key contribution to bringing the concept of the Akasha into theambit of contemporary science, and relating it to our understanding ofconsciousness. A book for all serious students of cosmos andconsciousness." -Dr. Ervin Laszlo,Author of Science andthe Akashic Field
