Hungarian-born Erdős believed that the meaning of life was to prove and conjecture. His work in the United States and all over the world has earned him the titles of the century's leading number theorist and the most prolific mathematician who ever lived. Erdős's important work has proved pivotal to the development of computer science, and his unique personality makes him an unforgettable character in the world of mathematics. Incapable of the smallest of household tasks and having no permanent home or job, he was sustained by the generosity of colleagues and by his own belief in the beauty of numbers. Witty and filled with the sort of mathematical puzzles that intrigued Erdős and continue to fascinate mathematicians today, My Brain Is Open is the story of this strange genius and a journey in his footsteps through the world of mathematics, where universal truths await discovery like hidden treasures and where brilliant proofs are poetry.

    Covert information warfare is being waged by world powers, rogue states—such as Russia, China, Iran, and North Korea—and even terrorist groups like ISIS. This conflict has been designed to defeat and ultimately destroy the United States. This new type of warfare is part of the Information Age that has come to dominate our lives. In iWar, Bill Gertz describes how technology has completely revolutionized modern warfare, how the Obama administration failed to meet this challenge, and what we can and must do to catch up and triumph over this timely and important struggle.

    The Clay Mathematics Institute is offering a prize of $1 million to anyone who can discover a general solution to the problem. In this book, Avner Ash and Robert Gross guide readers through the mathematics they need to understand this captivating problem.The key to the conjecture lies in elliptic curves, which are cubic equations in two variables. These equations may appear simple, yet they arise from some very deep--and often very mystifying--mathematical ideas. Using only basic algebra and calculus while presenting numerous eye-opening examples, Ash and Gross make these ideas accessible to general readers, and in the process venture to the very frontiers of modern mathematics. Along the way, they give an informative and entertaining introduction to some of the most profound discoveries of the last three centuries in algebraic geometry, abstract algebra, and number theory. They demonstrate how mathematics grows more abstract to tackle ever more challenging problems, and how each new generation of mathematicians builds on the accomplishments of those who preceded them. Ash and Gross fully explain how the Birch and Swinnerton-Dyer Conjecture sheds light on the number theory of elliptic curves, and how it provides a beautiful and startling connection between two very different objects arising from an elliptic curve, one based on calculus, the other on algebra.

    At the age of nineteen and a half, attracted by a strange and irresistible urge to go to the Himalayas, he left home. At the Vyasa Cave, beyond the Himalayan shrine of Badrinath, he met his Master and lived with him for three and a half years, wandering freely, the length and breadth of the snow clad Himalayan region. What he learnt from his Master Maheshwarnath Babaji, transformed his consciousness totally. Back in the plains, he, as instructed by his Master, lived a normal life, working for a living, fulfilling his social commitments and at the same time preparing himself to teach all that he had learnt and experienced. At a signal from his Master he entered the teaching phase of his life. Today, he travels all over the world to share his experiences and knowledge. Equally at home in the religious teachings of most major religions, Sri M, born as Mumtaz Ali Khan, says “Go to the core. Theories are of no use.” Sri M is married and has two children. During 2015-16 Sri M undertook the Walk of Hope, from Kanyakumari to Kashmir for 15 months covering a distance of 7500 kms, spreading the message of peace and harmony to restore the nation fit enough to be bequeathed to the future generations. He leads a simple life – teaching and heading the Satsang Foundation, a charitable concern promoting excellence in education. At present he lives in Madanapalle, Andhra Pradesh, three hours drive from Bangalore.
