Mr g: A Novel About The Creation


Alan Lightman - 1998
    Barraged by the constant advisements and bickerings of Aunt Penelope and Uncle Deva, who live with their nephew in the shimmering Void, Mr g proceeds to create time, space, and matter. Then come stars, planets, animate matter, consciousness, and, finally, intelligent beings with moral dilemmas. Mr g is all powerful but not all knowing and does much of his invention by trial and error.Even the best-laid plans can go awry, and Mr g discovers that with his creation of space and time come some unforeseen consequences—especially in the form of the mysterious Belhor, a clever and devious rival. An intellectual equal to Mr g, Belhor delights in provoking him: Belhor demands an explanation for the inexplicable, requests that the newly created intelligent creatures not be subject to rational laws, and maintains the necessity of evil. As Mr g watches his favorite universe grow into maturity, he begins to understand how the act of creation can change himself, the Creator.With echoes of Calvino, Rushdie, and Saramago, combining science, theology, and moral philosophy, Mr g is a stunningly imaginative work that celebrates the tragic and joyous nature of existence on the grandest possible scale.

Machine Learning: Fundamental Algorithms for Supervised and Unsupervised Learning With Real-World Applications


Joshua Chapmann - 2017
    Right?! Machine Learning is a branch of computer science that wants to stop programming computers using a detailed list of commands to follow blindly. Instead, their aim is to implement high-level routines that teach computers how to approach new and unknown problems – these are called algorithms. In practice, they want to give computers the ability to Learn and to Adapt. We can use these algorithms to obtain insights, recognize patterns and make predictions from data, images, sounds or videos we have never seen before – or even knew existed. Unfortunately, the true power and applications of today’s Machine Learning Algorithms remain deeply misunderstood by most people. Through this book I want fix this confusion, I want to shed light on the most relevant Machine Learning Algorithms used in the industry. I will show you exactly how each algorithm works, why it works and when you should use it.

आज भी खरे हैं तालाब


Anupam Mishra - 1993
    The book focuses on how to save the ancient water resources which have been neglected for quite a long time in India. This book holds a place in the list of best thirty books that have been published so far. This book has been translated in almost all Indian languages and quite a few foreign languages as well. There also exists a Braille version of this book. When it got published, it attracted the attention of a huge chunk of people and around two lac copies of books are known to have reached people across various places. The book, basically a report based book talks about how every household in arid regions could have their own water harvesting facility, a technique that has been in place for centuries. His approach towards life was something we do not find easily in the modern times. Moreover, this book has no copyright and can be reprinted and republished as and when one wants to. It is intriguing as to how this book could have had such an impact on the public, and on the society as a whole.

The Concussion Crisis: Anatomy of a Silent Epidemic


Linda Carroll - 2011
    On playing fields across America, lives are being derailed by seemingly innocuous jolts to the head. From the peewees to the pros, concussions are reaching epidemic proportions. This book brings that hidden epidemic and its consequences out of the shadows. As frightening as the numbers are—estimates of sports-related concussions range from 1.6 million to 3.8 million annually in the United States—they can’t begin to explain the profound impact of a hidden health problem that can strike any of us. It is becoming increasingly clear that concussions, like severe head traumas, can rob us of our memory, our mental abilities, our very sense of self. Because the damage caused by a concussion is rarely visible to the naked eye or even on a brain scan, no one knows how many millions might be living lives devastated by an invisible injury too often shrugged off as “just a bump on the head.” This book puts a human face on a huge public health crisis. Through narratives that chronicle the poignant experiences of real people struggling with this invisible and often unrecognized brain injury, Linda Carroll and David Rosner bring home its potentially devastating consequences. Among those you will meet are a high school football player whose college dreams were derailed by a series of undiagnosed concussions, a hard-driving soccer star whose own struggles with concussions pushed her to crusade for safety reform as a coach and soccer mom, and an economist who lost her career because of lingering concussion symptoms from a fender bender. The Concussion Crisis weaves these human dramas with compelling stories of scientists and doctors who are unraveling the mysteries of how an invisible injury can wreak such havoc. It takes readers into the top labs, where scientists are teasing out what goes wrong in the brain after a jolt to the head, and into the nation’s leading concussion clinic, where patients get cutting-edge management and treatment. Carroll and Rosner analyze the cultural factors that allowed this burgeoning epidemic to fester unseen and untreated. They chronicle the growing public awareness sparked by the premature retirements of superstars like NFL quarterbacks Troy Aikman and Steve Young. And they argue for an immediate change in a macho culture that minimizes the dangers inherent in repeated jolts to the head. The Concussion Crisis sounds an urgent wake-up call to parents, coaches, trainers, doctors, and the athletes themselves. The book will stand as the definitive exploration of this heretofore-silent health crisis. It should be required reading for every parent with a child playing sports—in fact, by everyone who has ever suffered a hard bump on the head.

Cosmological Koans: A Journey to the Heart of Physical Reality


Anthony Aguirre - 2019
    Through more than fifty Koans—pleasingly paradoxical vignettes following the ancient Zen tradition—leading physicist Anthony Aguirre takes the reader across the world from West to East, and through ideas spanning the age, breadth, and depth of the Universe.Using these beguiling Koans (Could there be a civilization on a mote of dust? How much of your fate have you made? Who cleans the universe?) and a flair for explaining complex science, Aguirre covers cosmic questions that scientific giants from Aristotle to Galileo to Heisenberg have grappled with, from the meaning of quantum theory and the nature of time to the origin of multiple universes.A playful and enlightening book, Cosmological Koans explores the strange hinterland between the deep structure of the physical world and our personal experience of it, giving readers what Einstein himself called “the most beautiful and deepest experience” anyone can have: a sense of the mysterious.

Empire of the Stars: Obsession, Friendship and Betrayal in the Quest for Black Holes


Arthur I. Miller - 2005
    Subrahmanyan Chandrasekhar--Chandra, as he was called--calculated that certain stars would suffer a strange and violent death, collapsing to virtually nothing. This extraordinary claim, the first mathematical description of black holes, brought Chandra into direct conflict with Sir Arthur Eddington, one of the greatest astrophysicists of the day. Eddington ridiculed the young man's idea at a meeting of the Royal Astronomy Society in 1935, sending Chandra into an intellectual and emotional tailspin--and hindering the progress of astrophysics for nearly forty years. Empire of the Stars is the dramatic story of this intellectual debate and its implications for twentieth-century science. Arthur I. Miller traces the idea of black holes from early notions of "dark stars" to the modern concepts of wormholes, quantum foam, and baby universes. In the process, he follows the rise of two great theories--relativity and quantum mechanics--that meet head on in black holes. Empire of the Stars provides a unique window into the remarkable quest to understand how stars are born, how they live, and, most portentously (for their fate is ultimately our own), how they die. It is also the moving tale of one man's struggle against the establishment--an episode that sheds light on what science is, how it works, and where it can go wrong. Miller exposes the deep-seated prejudices that plague even the most rational minds. Indeed, it took the nuclear arms race to persuade scientists to revisit Chandra's work from the 1930s, for the core of a hydrogen bomb resembles nothing so much as an exploding star. Only then did physicists realize the relevance, truth, and importance of Chandra's work, which was finally awarded a Nobel Prize in 1983. Set against the waning days of the British Empire and taking us right up to the present, this sweeping history examines the quest to understand one of the most forbidding phenomena in the universe, as well as the passions that fueled that quest over the course of a century.

Quantum Man: Richard Feynman's Life in Science


Lawrence M. Krauss - 2011
    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.

Stephen Hockman - 2013
    Often, a photographer will spend long days capturing photos only to return with a set of images that he or she is not completely satisfied with. Sure, the lighting and exposure may have turned out great, but the overall composition of the photos leaves something to be desired. In short, they lack that “wow” factor that they see in other photographers’ shots.Composition is the foundation in which great photography is built upon. A photo may be properly lit and contain good subject matter, but if it is doesn’t have good composition it will never be considered more than an amateur shot. How can you overcome this? We’ll teach you in this book. Finally, a Book on the Art of Photography that Teaches Tips and Tricks for Creative Composition! Our intention with this book is to teach you the tips and tricks professionals use to craft a great image design and learn how to incorporate these into composition that will lay the foundation for you to create amazing photos. Once you master the art of photography composition, you’ll know exactly what elements it takes to compose a great shot before you even touch the shutter button! As a result, it will free you up to concentrate on the other ingredients that go into making a beautiful photograph.Digital photography composition techniques you'll learn include: - How to develop the ability to see and shoot great digital photographs- Multiple ways in which to compose the best shot, regardless of subject matter- What the rule of thirds is and how to use it to your advantage- Where to place dominant vertical or horizontal subjects within the frame for maximum results- How to effectively use symmetry in photography- Understanding balance and visual weight within a photo- How to use lines in photography- How each type of line (horizontal, vertical, diagonal and curved) can be used to evoke a specific feeling within the viewer- How to instantly make a boring composition more dynamic- Ways in which to use different camera angles to add interest to a photo- How to master Out of Focus Foreground Framing, a signature style of many professional photographers- Unique ways to composing better backgrounds in any situation- How less can actually be more in photography- and much more!If you own a camera you owe it to yourself to learn how to master the art of composition in photography.

The Principia: Mathematical Principles of Natural Philosophy


Isaac Newton - 1687
    Even after more than three centuries and the revolutions of Einsteinian relativity and quantum mechanics, Newtonian physics continues to account for many of the phenomena of the observed world, and Newtonian celestial dynamics is used to determine the orbits of our space vehicles.This completely new translation, the first in 270 years, is based on the third (1726) edition, the final revised version approved by Newton; it includes extracts from the earlier editions, corrects errors found in earlier versions, and replaces archaic English with contemporary prose and up-to-date mathematical forms. Newton's principles describe acceleration, deceleration, and inertial movement; fluid dynamics; and the motions of the earth, moon, planets, and comets. A great work in itself, the Principia also revolutionized the methods of scientific investigation. It set forth the fundamental three laws of motion and the law of universal gravity, the physical principles that account for the Copernican system of the world as emended by Kepler, thus effectively ending controversy concerning the Copernican planetary system.The illuminating Guide to the Principia by I. Bernard Cohen, along with his and Anne Whitman's translation, will make this preeminent work truly accessible for today's scientists, scholars, and students.

The Vital Question: Energy, Evolution, and the Origins of Complex Life


Nick Lane - 2015
    Yet there’s a black hole at the heart of biology. We do not know why complex life is the way it is, or, for that matter, how life first began. In The Vital Question, award-winning author and biochemist Nick Lane radically reframes evolutionary history, putting forward a solution to conundrums that have puzzled generations of scientists.For two and a half billion years, from the very origins of life, single-celled organisms such as bacteria evolved without changing their basic form. Then, on just one occasion in four billion years, they made the jump to complexity. All complex life, from mushrooms to man, shares puzzling features, such as sex, which are unknown in bacteria. How and why did this radical transformation happen?The answer, Lane argues, lies in energy: all life on Earth lives off a voltage with the strength of a lightning bolt. Building on the pillars of evolutionary theory, Lane’s hypothesis draws on cutting-edge research into the link between energy and cell biology, in order to deliver a compelling account of evolution from the very origins of life to the emergence of multicellular organisms, while offering deep insights into our own lives and deaths.Both rigorous and enchanting, The Vital Question provides a solution to life’s vital question: why are we as we are, and indeed, why are we here at all?

Wrinkles in Time


George Smoot - 1993
    Dr. George Smoot, a distinguished cosmologist and adventurer whose quest for cosmic knowledge had taken him from the Brazilian rain forest to the South Pole, unveiled his momentous discovery, bringing to light the very nature of the universe. For anyone who has ever looked up at the night sky and wondered, for anyone who has ever longed to pull aside the fabric of the universe for a glimpse of what lies behind it. Wrinkles in Time is the story of Smoot's search to uncover the cosmic seeds of the universe.Wrinkles in Time is the Double Helix of cosmology, an intimate look at the inner world of men and women who ask. "Why are we here?" It tells the story of George Smoot's dogged pursuit of the cosmic wrinkles in the frozen wastes of Antarctica, on mountaintops, in experiments borne aloft aboard high-altitude balloons, U-2 spy planes, and finally a space satellite. Wrinkles in Time presents the hard science behind the structured violence of the big bang theory through breathtakingly clear, lucid images and meaningful comparisons. Scientists and nonscientists alike can follow with rapt attention the story of how, in a fiery creation, wrinkles formed in space ultimately to become stars, galaxies, and even greater delicate structures. Anyone can appreciate the implications of a universe whose end is written in its beginnings - whose course developed according to a kind of cosmic DNA, which guided the universe from simplicity and symmetry to ever-greater complexity and structure. As controversial as it may seem today, Wrinkles in Time reveals truths that, in an earlier century, would have doomed its proclaimers to the fiery stake. For four thousand years some people have accepted the Genesis account of cosmic origin; for most of this century, scientists debated two rival scientific explanations known as the steady state and big bang theories. And now, Wrinkles in Time tells what really happened. The personal story behind astrophysicist George Smoot's incredible discovery of the origin of the cosmos, hailed by Stephen Hawking as "The scientific discovery of the century, if not of all time."
