Life was simple when the dynamic, the spectral and the resolving powers of our instruments were small. One observed whole objects - planets, stars, sunspots, galaxies, often in rainbow colours. Then the revolution occurred: we acquired the centimetric eyes, the mil limetric eyes, the infrared eyes, the ultraviolet eyes, the X-ray eyes and the ,-ray eyes. With these we see mottles on the surface of stars, streams in sunspots, and spirals in nuclei of galaxies. We see regions of multiple mass densities and temperatures in a precari ous balance, losing it occasionally, exhaling flares. The universe is timed, cosmic phenomena are clocked; eternity is lost and variabil ity is bought. Microarcsecond resolutions revealed stirring and siz zling interiors underneath serene surfaces. Short durations and small scales demanded employing a discipline with similar attributes - the discipline of Plasmas and Fluids - known more for its complexity than for its felicity. Some would like to wish it away. We shall learn about plasmas for it is too little familiarity that breeds fear. Complexity can be systemized, to a large extent, by looking for a common denominator among apparently disparate phe nomena. It is not immediately obvious what the contents and the style of a graduate level course on plasmas and fluids aimed at understanding astrophysical phenomena should be. Plasmas and fluids are huge subjects by themselves. The cosmic phenomena where plasmas and fluids playa definite role are equally diverse and numerous.
Most astronomers believe that the universe began about 15 billion years ago when an explosion led to its expansion and cooling. The present state of the universe compels us to believe that the universe was extremely hot and dense in its infancy. In the beginning there was intense radiation. The photons produced equal amounts of matter and antimatter and a plasma soup of particles and antiparticles was present. Plasma is the first state of matter from which all the other states originated. This book discusses the diversity of cosmic and terrestrial plasmas found in the early universe, galactic and intergalactic media, stellar atmospheres, interstellar spaces, the solar system and the Earth's ionosphere, and their observability with the most recent telescopes such as the Chandra X-ray telescope and gamma ray telescopes. It deals with different ways of creating plasmas such as thermal, pressure and radiative ionization for laboratory and cosmic plasmas.
This book presents a pedagogical account of the physics of partially ionized plasmas starting from first principles. It includes a set of unsolved problems at the cutting edge of research in the field, from the formulation to the application level.

The book is an exposition of life behind the glamour. It speaks on the pains the artist undergoes to create his image and more to retain the intellection. The stories are based on personal interactions that could never become public. Even if some plots trickled out it failed to arouse concern and empathy. These anecdotes underline various phases of Hindi cinema and despite all its technical superiority, it could not shrug off the system that demeans artists once they are not patronized or engaged. It has references to individuals, film families and some unsaid instances that built the concept of the book. A major portion of the book is devoted to the second rung of artists or character artists, whose contributions howsoever prodigious and impressionable have often been ignored. Cinema pandered more to the star system than its realities. A character artist remains in focus till he is there. Many names that enthused the box office charts are long erased. Rightly everything that glitters is not glamour. The book quotes instances of sham camaraderie in the film world that in reality is ruthless and operates without remorse. Yet, it continues to attract and absorb new talent and that is the peculiarity of show business.
He was an intelligent and notorious devil who emerged directly from the depths of nightmares, both intriguing and frightening. Gifted with the ability to escape capture for decades, if not for a particular day, he would have never been chronicled into the crime records. he dreadful challenge to the crime squad department was that his targets were exposed to the world before he began his hunt; a deadly and dangerous game. Their duty was to protect them from his clutches. To their misery, the death of a famed Godman shocks the nation. The horrors inside his mind spilled out into the world and into the ordinary lives of those 5 random individuals, without any recognisable pattern or logic, until his motives were exposed by a crime squad officer by tracing and decrypting every piece of puzzle at microscopic close. He kills, not for passion, fun or revenge, but for a definite mysterious goal. After each assassination, a dark secret surfaces creating shockwaves from the clues of his letters. He justifies his assassinations by claiming they are destined to happen, with links to many incidents, starting from the very inception of the world, Vedic writings, Ramayana and Mahabharata, to the present-day Yuga. Were these deaths linked to Godman? Was he a serial Killer or Psychopath or Avatar? Was the crime force successful in hunting that Invincible Assassin finally?
I had the opportunity to work with the author, Vinod Kapoor, at both Doordarshan and All India Radio (AIR). His writings always carried clarity of opinion. The book is not a history of broadcasting but gently touches the contours of that chequered march of broadcasting though in an interesting manner. The author has written with flowing interest, subjects like the controversy about language, the way dramas gained prominence, the scene at the AIR during the Mahatma Gandhi assassination and also when the nation attained freedom. There are references to how AIR helped Hindi cinema grow and provide a stream of artists it nurtured. He recapitulates the contributions of some known broadcasters with anecdotal references that shaped the medium. He has strongly expressed his displeasure on denying functional freedom to the professionals, which Prasar Bharati Act had promised. He has not minced expressions in excoriating the non-professionals take charge, which, in reality, brought the downfall of Public Broadcasting. There are points where he could not restrain his anguish but that went with reason and mood. Broadcasting is a very vast subject and one cannot cover every aspect of it. Yet, the author has made a valiant attempt. The author has flair for writing and done some of the chapters with extra zest like his essays titled Zest for Music, Voices That Ring or The Mentors. This reminded me of his research on certain individuals, which showcases the enormity of broadcasting. There is amplified mention of veteran actors Jahanara Kajjan, Achla Sachdev, Om Prakash and film composers, Roshan and Ravi, who represented the entire gamut of artists who scored big later.

To be in merit what does an aspirant need? That needs to (1) Read well (2) Write well (3) understand well, (4) Memorize well, (5) Retain well And (6) Recollect accurately.... Agree!!!! This is called Learning cycle. If the mistakes are less, the chances of Merit are more!!Where do you make mistakes mostly, in recollection right?? Because you learned how to read, write and understand well...even you memorize before the exam and you learned repetition and cramming way of memorization. BUT have you learned HOW TO RECOLLECT? What is the best way of accurate and complete recollection? WE DO NOT WANT TO MEMORISE BUT WE DO WANT TO REMEMBER !!In this book you will not only learn How to memorize fast, how to retain longer and stronger but also you will learn How to recollect!! Remember we get marks only for recollection of knowledge what you obtain in the whole year. This means, reading, writing, understanding and memorizing are learning steps and recollection is the test of learning so recollection science can also be called as Exam Science. You will learn here,being meritorious, not only in studies but also in life with Brain Science.
This book focuses on India’s foreign policy towards Sri Lanka before the Indo-Sri Lanka Accord (ISLA) in July 1987 and India’s military intervention after the ISLA. The post-intervention developments brought strategic changes in India’s Sri Lanka policy. However, after leadership change in both the countries, India confined its policy to moral support and decided to abstain from direct intervention or involvement in Sri Lanka’s domestic politics. After the demise of the LTTE and its leadership in 2009, India played a constructive role in rebuilding infrastructure in Sri Lanka. The book also focuses on the developments of the relationships between India and Sri Lanka in the post-IPKF period and the bilateral developments in the Post - LTTE periods.

In his debut book, Vinod Kumar Nagpal, the author, takes us back to the early 1960s. This is the story of a child who is gullible, inquisitive, and curious about nature, religion, and God while he is still five years old. He poses a lot of questions to his father about mythology, religion, God, and the partition of Bharat, as his parents migrated from Western Punjab of the then undivided Bharat at the time of partition of the country. His father narrates a lot of incidences/mythological stories to his young son and also shares with him painful memories of partition and his struggles thereafter. Incidences/stories told by his father carry many good lessons. But because of his careless nature and aversion to studies, he does not pay heed to those lessons and suffers as a consequence. When he grows up, he realizes his mistakes and tries to re-learn those lessons which he had unlearned. Is he able to resurrect his life? A must-read to recollect childhood memories and get nostalgic. The book also discusses what God wants from us, what the actual meaning of religion is, and how one must conduct oneself.
