    For centuries, the power of zero savored of the demonic; once harnessed, it became the most important tool in mathematics. Zero follows this number from its birth as an Eastern philosophical concept to its struggle for acceptance in Europe and its apotheosis as the mystery of the black hole. Today, zero lies at the heart of one of the biggest scientific controversies of all time, the quest for the theory of everything. Elegant, witty, and enlightening, Zero is a compelling look at the strangest number in the universe and one of the greatest paradoxes of human thought.

    He is the founder of Infosys, a global software consulting company which he started with six other professionals and a seed capital of Rs. 10,000 in 1981. Not only did NRNM lead it to become a top ranking Information Technology company in the world, he also showed that it is possible to do business ethically and achieve success without bending any laws or making compromises.This book takes you through the fascinating journey of a seventeen year old who had to sacrifice his entry into the prestigious Indian Institute of Technology because his father did not have money to pay his fees, and who ultimately came up in life to head a global Information Technology company. NRN Murthy had no money, no family backing, but just a quiet gritty determination, and faith in what he believed was the future of business.

    Using the data they are constantly collecting about where we travel, where we shop, what we buy, and what interests us, they can begin to predict our daily habits, and increasingly we are relinquishing our decision-making to algorithms. Are we giving this up too easily?Without understanding what mathematics can and can't do it is impossible to get a handle on how it is changing our lives. Outnumbered is a journey to the dark side of mathematics, from how it dictates our social media activities to our travel routes. David Sumpter investigates whether mathematics is crossing dangerous lines when it comes to what we can make decisions about.This book will show how math impacts all parts of our lives: from the algorithms that decide whom we interact with to the statistical methods that categorize us as potential criminals. It tests financial algorithms that purport to generate money from nothing, and reveals that we are constantly manipulated by the math used by others, from algorithms choosing the news we hear to automated hospital waiting lists deciding whether we receive treatment.Using interviews with those people working at the cutting edge of mathematical and data research, Outnumbered will explain how math and stats work in the real world, and what we should and shouldn't worry about.

    I've been there and have struggled with suicidal thoughts and plans. I can share with you what I did to not only survive, but to tolerate depression, live with it, and function acceptably most of the time, interspersed with periods of contentment, happiness, and joy. My strategies may well work for you. My goal is to save lives. The primary motivation for presenting my history is to encourage others who grapple with either chronic depression or occasional bouts. I hope my journey resonates with some, validates feelings, and sparks the thoughts "I'm not alone" and "I will feel better." This book can also help family members and friends of the mentally ill, and their caregivers, find compassion and enable them to understand the struggle. Transcending Depression differs from many other books on the topic in that it is not grounded in clinical experience, scientific research, or empirical evidence, which may make it more approachable than some. It's not a how-to book, not a model for depressed people to follow, not a toolbox. On the contrary, it shows rather than tells the reader what he or she might do to feel better. Appendices include my Depression Survival Guide, which offers 36 suggestions to bring relief, and Chess in the Labyrinth, a metaphor that compares defeating depression to winning a chess game.

    

    Here Lawrence M. Krauss, himself a theoretical physicist and best-selling author, offers a unique scientific biography: a rollicking narrative coupled with clear and novel expositions of science at the limits. An immensely colorful persona in and out of the office, Feynman revolutionized our understanding of nature amid a turbulent life. Krauss presents that life—from the death of Feynman’s childhood sweetheart during the Manhattan Project to his reluctant rise as a scientific icon—as seen through the science, providing a new understanding of the legacy of a man who has fascinated millions. An accessible reflection on the issues that drive physics today, Quantum Man captures the story of a man who was willing to break all the rules to tame a theory that broke all the rules.

    You’ve deloaded, done your recovery session, even taken a hot bath. Oh how nice a massage would be right now.

Trigger points and tight muscles are a common cause of muscle and joint pain. They can refer pain to other areas as well as causing problems at the site itself. Although they don't count for all the pain you might be suffering from, releasing them can certainly help get rid of a lot of the pain, if not clear up your problem entirely. Have you ever been to the doctor and he or she told you that theres nothing wrong, even after extensive scans? You might simply need some work on your muscles. Keeping the muscle tissue quality high will help reduce the amount of injuries you suffer from, improve your posture as well as help a lot of muscle and joint pain.In this book you can learn how to effectively get rid of shoulder pain, neck pain, upper and lower back pain, hip and glute pain and stiffness, leg and knee pain, calf pain, ankle stiffness, Achilles problems and much more.Actual excerpt from the book of how I discovered this great technique."When I was playing in Germany, I had really bad shoulder pain. The kind that ran down to my fingers and made me unable to put my arms over my head. One night trying to get relief I grabbed my old Motorola and started laying on it, with it digging in under my shoulder. Slowly and excruciatingly I released the rotator cuff muscles and gave myself a pain free range of motion that I had only dreamed of before. Needless to say, I thought I was a genius and upgraded to a tennis ball pretty quickly."

    By investing some of the lesser-known corners of psychology, neuroscience, physics, history, and even crime, all through the lens of trickery and illusion, Fooling Houdini arrives at a host of startling revelations about how the mind works--and why, sometimes, it doesn’t.

    Blade Runner, The Matrix, Star Wars, Avatar, Star Trek, Ready Player One and Avengers show us futuristic worlds where holograms, intelligent robots, smart devices, virtual avatars, digital transactions, and universe-scale teleportation work together perfectly, somehow seamlessly combining the virtual and the physical with the mechanical and the biological. Science fiction has done an excellent job describing a vision of the future where the digital and physical merge naturally into one — in a way that just works everywhere, for everyone. However, none of these visionary fictional works go so far as to describe exactly how this would actually be accomplished. While it has inspired many of us to ask the question—How do we enable science fantasy to become....science fact? The Spatial Web achieves this by first describing how exponentially powerful computing technologies are creating a great “Convergence.” How Augmented and Virtual Reality will enable us to overlay our information and imaginations onto the world. How Artificial Intelligence will infuse the environments and objects around us with adaptive intelligence. How the Internet of Things and Robotics will enable our vehicles, appliances, clothing, furniture, and homes to become connected and embodied with the power to see, feel, hear, smell, touch and move things in the world, and how Blockchain and Cryptocurrencies will secure our data and enable real-time transactions between the human, machine and virtual economies of the future. The book then dives deeply into the challenges and shortcomings of the World Wide Web, the rise of fake news and surveillance capitalism in Web 2.0 and the risk of algorithmic terrorism and biological hacking and “fake-reality” in Web 3.0. It raises concerns about the threat that emerging technologies pose in the hands of rogue actors whether human, algorithmic, corporate or state-sponsored and calls for common sense governance and global cooperation. It calls for business leaders, organizations and governments to not only support interoperable standards for software code, but critically, for ethical, and social codes as well. Authors Gabriel René and Dan Mapes describe in vivid detail how a new “spatial” protocol is required in order to connect the various exponential technologies of the 21st century into an integrated network capable of tracking and managing the real-time activities of our cities, monitoring and adjusting the supply chains that feed them, optimizing our farms and natural resources, automating our manufacturing and distribution, transforming marketing and commerce, accelerating our global economies, running advanced planet-scale simulations and predictions, and even bridging the gap between our interior individual reality and our exterior collective one. Enabling the ability for humans, machines and AI to communicate, collaborate and coordinate activities in the world at a global scale and how the thoughtful application of these technologies could lead to an unprecedented opportunity to create a truly global “networked” civilization or "Smart World.” The book artfully shifts between cyberpunk futurism, cautionary tale-telling, and life-affirming call-to-arms. It challenges us to consider the importance of today’s technological choices as individuals, organizations, and as a species, as we face the historic opportunity we have to transform the web, the world, and our very definition of reality.
