A modern introduction to Newtonian dynamics and the basics of special relativity, this book discusses standard topics such as Newton¿s laws of motion, energy, linear and angular momentum, rigid body dynamics, and oscillations, then goes on to introduce modern topics such as symmetries, phase space, nonlinear dynamics and chaos. The author presents Newton¿s equation of motion as a differential equation, bringing out key issues such as phase space and determinism in mechanical systems and helps introduce modern research topics such as chaos theory in a natural way. He highlights key assumptions of Newtonian mechanics and incorporates numerical solutions of many mechanical systems using MATLAB¿.
An up-to-date comprehensive text useful for graduate students and academic researchers in the field of energy transfers in fluid flows. The initial part of the text covers discussion on energy transfer formalism in hydrodynamics and the latter part covers applications including passive scalar, buoyancy driven flows, magnetohydrodynamic (MHD), dynamo, rotating flows and compressible flows. Energy transfers among large-scale modes play a critical role in nonlinear instabilities and pattern formation and is discussed comprehensively in the chapter on buoyancy-driven flows. It derives formulae to compute Kolmogorov's energy flux, shell-to-shell energy transfers and locality. The book discusses the concept of energy transfer formalism which helps in calculating anisotropic turbulence.
Review: "This excellent book of Prof. Verma is a single resource which a student can use to learn the fast-developing field of computational science. In addition to the description of Python language, it provides a broad overview of hardware, software, classic numerical methods, and everything in between. I recommend it strongly to all!" -- Prof. Prateek Sharma, IISc Bengaluru Key Features of the Book: Perfect book for introduction to practical numerical algorithms and programs for advanced undergraduate and beginning graduate students. Introduces Python programming language and its modules related to numerical computing Covers Numpy, Matplotlib, and Scipy modules in details. Illustrates how...
Eleven papers concentrate on lesser-researched forms of communication--ideophones, dialects, and sign language. They also explore the relationship between language and society in a broad framework in order to emphasize not only the validity but the centrality of language variety and variation. Taken together, the essays argue for moving away from the classic, narrow view to a more informed and intelligent one of what language means for individuals and groups.

Gravity pervades the whole universe; hence buoyancy drives fluids everywhere including those in the atmospheres and interiors of planets and stars. Prime examples of such flows are mantle convection, atmospheric flows, solar convection, dynamo process, heat exchangers, airships and hot air balloons. In this book we present fundamentals and applications of thermal convection and stratified flows.Buoyancy brings in extremely rich phenomena including waves and instabilities, patterns, chaos, and turbulence. In this book we present these topics in a systematic manner. First we present a unified treatment of linear theory that yields waves and thermal instability for stably and unstably-stratifie...

Mitigating the Risks of a 21st Century Climate Switch (to global cooling) and Running Out of Oil and Gas: There is an urgent need to prepare the world for a 21st century climate switch to a cooling phase, and this current grand solar minimum is a prime time for that switch. The world will face natural climate change-related risks during the current grand solar minimum—risks dismissed or ignored by the Intergovernmental Panel on Climate Change (IPCC) because of its constraining Articles 1 and 2. Solar scientists expert in climate change are warning us of a 21st century global cooling, but the IPCC process has dismissed their science and that of other climate sub-disciplines. Climate-forcing...
The Eighteenth Round Table of South Asian Language Analysis (SALA) was organised by the Centre of Linguistics and English, School of Languages, Jawaharlal Nehru University, New Delhi (India), Janurary 4-6, 1997. The conference was attended by scholars from all over the world and about 150 papers were presented in 20 parallel sessions and plenary sessions. This volume is a representative sample of the breadth and quality of research that is being carried out in South Asian linguistics today.
Close to half of the 6,000 languges spoken in the world are doomed or likely to disappear in the foreseeable future. The disappearance of any language is an irreparable loss for the heritage of all humankind. This new edition of the Atlas, first published in 1996, is intended to give a graphic picture of the magnitude of the problem and a comprehensive list of languages in danger.
