This user-friendly self-study guide is aimed at the general reader who is motivated to tackle that not insignificant challenge. The book is written using straightforward and accessible language, with clear derivations and explanations as well as numerous fully solved problems. For those with minimal mathematical background, the first chapter provides a crash course in foundation mathematics. The reader is then taken gently by the hand and guided through a wide range of fundamental topics, including Newtonian mechanics; the Lorentz transformations; tensor calculus; the Einstein field equations; the Schwarzschild solution (which gives a good approximation of the spacetime of our Solar System); simple black holes and relativistic cosmology. Following the historic 2015 LIGO (Laser Interferometer Gravitational-Wave Observatory) detection, there is now an additional chapter on gravitational waves, ripples in the fabric of spacetime that potentially provide a revolutionary new way to study the universe. Special relativity helps explain a huge range of non-gravitational physical phenomena and has some strangely counter-intuitive consequences. These include time dilation, length contraction, the relativity of simultaneity, mass-energy equivalence and an absolute speed limit. General relativity, the leading theory of gravity, is at the heart of our understanding of cosmology and black holes.Understand even the basics of Einstein's amazing theory and the world will never seem the same again.

    As almost every photographer knows, the word -photograph- has its roots in two Greek words that, together, mean -drawing with light.- But what is less commonly acknowledged and understood is the role that shadow plays in creating striking, expressive imagery, especially in portraiture. It is through deft, nuanced use of both light and shadow that you can move beyond shooting simply ordinary, competent headshots into the realm of creating dramatic portraiture that can so powerfully convey a subject's inner essence, communicate a personal narrative, and express your photographic vision. In The Dramatic Portrait: The Art of Crafting Light and Shadow, Chris Knight addresses portraiture with a unique approach to both light and shadow that allows you to improve and elevate your own portraiture. He begins with the history of portraiture, from the early work of Egyptians and Greeks to the sublime treatment of light and subject by artists such as Caravaggio, Rembrandt, and Vermeer. Chris then dives into a deep, hands-on exploration of light, shadow, and portraiture, offering numerous lessons and takeaways. He covers: - The qualities of light: hard, soft, and the spectrum in between- The relationships between light, subject, and background, and how to control them- Lighting patterns such as Paramount, Rembrandt, loop, and split- Lighting ratios and how they affect contrast in your image- Equipment: from big and small modifiers to grids, snoots, barn doors, flags, and gels- Multiple setups for portrait shoots, including those that utilize one, two, and three lights- How color contributes to drama and mood, eliciting an emotional response from the viewer- How to approach styling your portrait, from wardrobe to background- The post-processing workflow, including developing the RAW file, maximizing contrast, color grading, retouching, and dodging and burning for heightened drama and effect- How all of these elements culminate to help you define your personal style and create your own narrative

    It spent over 63 weeks on The New York Times Bestseller list and reached the #1 spot in the Advice, How-To and Miscellaneous section of the list. In 1992, it was Publishers Weekly's longest running hardcover bestseller, with 35 weeks on the list.

    It presents in a unified manner an introduction to the mathematical theory underlying computer graphic applications. It covers topics of keen interest to students in engineering and computer science: transformations, projections, 2-D and 3-D curve definition schemes, and surface definitions. It also includes techniques, such as B-splines, which are incorporated as part of the software in advanced engineering workstations. A basic knowledge of vector and matrix algebra and calculus is required.

    Something we’ve turned a blind eye to for far too long. Dr. Leonardo Trasande, a pediatrician, professor, and world-renowned researcher, tells the story of how our everyday surroundings are making us sicker, fatter, and poorer.   Dr. Trasande exposes the chemicals that disrupt our hormonal systems and damage our health in irreparable ways. He shows us where these chemicals hide—in our homes, our schools, at work, in our food, and countless other places we can’t control—as well as the workings of policy that protects the continued use of these chemicals in our lives. Drawing on extensive research and expertise, he outlines dramatic studies and emerging evidence about the rapid increases in neurodevelopmental, metabolic, reproductive, and immunological diseases directly related to the hundreds of thousands of chemicals that we are exposed to every day. Unfortunately, nowhere is safe.   But, thanks to Dr. Trasande’s work on the topic, and his commitment to effecting change, this book can help. Through a blend of narrative, scientific detective work, and concrete information about the connections between chemicals and disease, he shows us what we can do to protect ourselves and our families in the short-term, and how we can help bring the change we deserve.

    Cohen show us that the antidote to our ever-growing rates of obesity and chronic diseases, such as heart disease and diabetes, lies not in our medical care system or in more health education but rather in how our environment affects our behavior.

    

    But by banning fat from our diets, we’ve deprived ourselves of considerable health benefits—and have actually sabotaged our own efforts to lose weight.Though they originally came from vastly different schools of thought about diet and weight loss, renowned nutritionist Jonny Bowden and well-respected physician Steven Masley independently came to the same conclusion about why so many people continually fail to shed pounds and get healthy. It all comes back to a distinction far more important than calories vs. carbs or paleo vs. plant-based: smart fat vs. dumb fat.In Smart Fat, they explain the amazing properties of healthy fat, including its ability to balance hormones for increased energy and appetite control, and its incredible anti-inflammatory benefits. The solution for slimming down—and keeping the pounds off for life—is to “smart-fat” your meals, incorporating smart fats with fiber, protein, and most importantly, flavor. Bowden and Masley identify smart fats, explain what not to eat, and provide a thirty-day meal plan and fifty recipes based on the magic formula of fat, fiber, protein, and flavor.It’s time to unlearn what we think we know about food. Getting smart about fat—and everything you eat—and learning to smart-fat your meals is the only solution you'll ever need.

    The 1980s were certainly loud, often garish and utterly fabulous - no matter how embarrassing the outfits were.There are so many elements, which made the 80s a truly great decade, but one of the greatest contributions, if not the greatest, is the mass introduction of affordable 8-bit home micro computers.These curious machines of geekdom changed the way we regarded computers and technology. No longer were they the sole perverse of tweed jacket clad scientists sporting unruly beards, micro computers were now forming a staple inventory in millions of homes.Much of the technology that we enjoy today, such as desktop computers, notebooks, tablets, gaming consoles and smart phones, all of which are often taken for granted, can be traced back to this innovative decade.If you were a child of the 80s and remember the joy of receiving your very first home computer or maybe a young adult who fondly remembers the excitement, then you will appreciate this unabashed reminiscence of a simpler time whose adolescent technological was on the cusp of great advancements.This book is intended as celebration and reflection of all the computer technology that made the 80s such a wonderful, pioneering period and follows the journey of a self confessed, teenaged computer geek who experienced and enjoyed every ground breaking moment, including publishing his own software.10 Print “The 80s are fab!”20 Goto 10RunAuthor's Comments:The current edition is dated 31st January 2016 and has been edited based on customer feedback.
