    Baby becomes distressed at feeding times and refuses to feed or eats very little despite obvious hunger. Why won’t he/she eat? This is a question parents ask numerous health professionals while searching for a solution. Babies are typically diagnosed with one, two or three medical conditions to explain their aversive feeding behavior during brief appointments. Consequently, many parents don’t receive an effective solution from the health professionals they consult. This is why this book is so necessary. Rowena Bennett is an Australian nurse who holds professional qualifications in various nursing fields including pediatrics, midwifery, child health, mental health and lactation consultant. She has over 20 years experience advising parents how to resolve infant feeding and sleeping problems. Rowena has helped over 1000 babies get over their aversion to bottle-feeding and enjoy feeding once again. Parents claim the relief is life changing. In Your Baby’s Bottle-feeding Aversion, Rowena describes the various reasons babies display aversive feeding behavior, explains how the reader can identify the cause, and describes effective solutions. Included are step-by-step instructions on how to resolve a behavioral feeding aversion that occurs as a result of being repeatedly pressured to feed - the most common of all reasons for babies to become averse to feeding. Your Baby’s Bottle-feeding Aversion provides practical professional feeding advice that not only makes good sense, it works!

    It's everything. From lions hunting as a pride to penguins huddling together to keep from freezing in the bitter Antarctic winter, many animals are dependent on complex social relationships for their survival. Powerful dynasties lay claim to vast swathes of territory, fighting off rivals and securing their hunting grounds for generations to come.Dynasties offers an immersive insight into the shifting hierarchies of animal families. Each chapter follows a different dynasty, from the Marsh Lions of the Masai Mara to rival packs of painted wolves, from a tiger protecting her newborn cubs to a chimpanzee troop and the penguin colonies of the Antarctic. Alongside tender moments when bonds are strengthened through grooming and play, the book charts the rivalries that tip the balance of power, when family members turn against each other and younger animals grow strong enough to challenge for control.With over 200 stunning photographs and insights from the crew of the BBC series, Dynasties reveals in astonishing detail the intricate social lives of our planet’s most fascinating animals.

    Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

    Coffee. Sunscreen. Vapes. George Zaidan reveals what will kill you, what won't, and why--explained with high-octane hilarity, hysterical hijinks, and other things that don't begin with the letter H. INGREDIENTS offers the perspective of a chemist on the stuff we eat, drink, inhale, and smear on ourselves. Apart from the burning question of whether you should eat that Cheeto, Zaidan explores a range of topics. Here's a helpful guide:Stuff in this book: - How bad is processed food? How sure are we?- Is sunscreen safe? Should you use it?- Is coffee good or bad for you?- What's your disease horoscope?- What is that public pool smell made of?- What happens when you overdose on fentanyl in the sun?- What do cassava plants and Soviet spies have in common?- When will you die?Stuff in other books: - Your carbon footprint- Food sustainability- GMOs- CEO pay- Science funding- Politics- Football- Baseball- Any kind of ball reallyZaidan, an MIT-trained chemist who cohosted CNBC's hit Make Me a Millionaire Inventor and wrote and voiced several TED-Ed viral videos, makes chemistry more fun than Hogwarts as he reveals exactly what science can (and can't) tell us about the packaged ingredients sold to us every day. Sugar, spinach, formaldehyde, cyanide, the ingredients of life and death, and how we know if something is good or bad for us--as well as the genius of aphids and their butts--are all discussed in exquisite detail at breakneck speed.

    Wilczek’s groundbreaking work in quantum physics was inspired by his intuition to look for a deeper order of beauty in nature. In fact, every major advance in his career came from this intuition: to assume that the universe embodies beautiful forms, forms whose hallmarks are symmetry—harmony, balance, proportion—and economy. There are other meanings of “beauty,” but this is the deep logic of the universe—and it is no accident that it is also at the heart of what we find aesthetically pleasing and inspiring.Wilczek is hardly alone among great scientists in charting his course using beauty as his compass. As he reveals in A Beautiful Question, this has been the heart of scientific pursuit from Pythagoras, the ancient Greek who was the first to argue that “all things are number,” to Galileo, Newton, Maxwell, Einstein, and into the deep waters of twentiethcentury physics. Though the ancients weren’t right about everything, their ardent belief in the music of the spheres has proved true down to the quantum level. Indeed, Wilczek explores just how intertwined our ideas about beauty and art are with our scientific understanding of the cosmos.Wilczek brings us right to the edge of knowledge today, where the core insights of even the craziest quantum ideas apply principles we all understand. The equations for atoms and light are almost literally the same equations that govern musical instruments and sound; the subatomic particles that are responsible for most of our mass are determined by simple geometric symmetries. The universe itself, suggests Wilczek, seems to want to embody beautiful and elegant forms. Perhaps this force is the pure elegance of numbers, perhaps the work of a higher being, or somewhere between. Either way, we don’t depart from the infinite and infinitesimal after all; we’re profoundly connected to them, and we connect them. When we find that our sense of beauty is realized in the physical world, we are discovering something about the world, but also something about ourselves.Gorgeously illustrated, A Beautiful Question is a mind-shifting book that braids the age-old quest for beauty and the age-old quest for truth into a thrilling synthesis. It is a dazzling and important work from one of our best thinkers, whose humor and infectious sense of wonder animate every page. Yes: The world is a work of art, and its deepest truths are ones we already feel, as if they were somehow written in our souls.

    His quick mastery of quantum mechanics earned him a place at Los Alamos working on the Manhattan Project under J. Robert Oppenheimer, where the giddy young man held his own among the nation’s greatest minds. There, Feynman turned theory into practice, culminating in the Trinity test, on July 16, 1945, when the Atomic Age was born. He was only twenty-seven. And he was just getting started. In this sweeping biography, James Gleick captures the forceful personality of a great man, integrating Feynman’s work and life in a way that is accessible to laymen and fascinating for the scientists who follow in his footsteps.

    A deep vibration shook the entire island. Jets of steam and ash emanated from the summit, followed by an explosion louder than any sound heard by Homo sapiens since our species evolved on Earth. The eruption of the Toba supervolcano released the energy of a million tons of explosives; seven hundred cubic miles of magma spewed outward in an explosion forty times larger than the largest hydrogen bomb and more than a thousand times as powerful as the Krakatau eruption in 1883. So much ash and debris was injected into the stratosphere that it partially blocked the sun's radiation and caused global temperatures to drop by five to nine degrees. It took a full decade for Earth to recover to its pre-eruption temperatures.When Humans Nearly Vanished presents the controversial argument that the Toba catastrophe nearly wiped out the human race, leaving only about a thousand to ten thousand breeding pairs of humans worldwide. Human genes today show evidence of a "genetic bottleneck," an effect seen when a population of organisms becomes so small that their genetic diversity is greatly reduced. This group of survivors could be the ancestors of all humans alive today. Donald R. Prothero explores the geological and biological evidence supporting the Toba bottleneck theory; reveals how the explosion itself was discovered; and offers insight into how the world changed afterward and what might happen if such an eruption occurred today. Prothero's riveting account of this calamitous supervolcanic explosion is not to be missed.

    Schwartz, Ph.D., there is compelling scientific evidence that we no longer have to accept God on faith alone. Through a multidisciplinary approach, Harvard University-educated Dr. Schwartz blends psychology, quantum physics, and mathematics to examine the science of spirit. Faith and science are not mutually exclusive, and a better understanding of their relationship can lead us to recognize how God operates in everything.Trained in the scientific method as an "open-minded skeptic," Dr. Schwartz was taught how to raise questions, turn them into hypotheses, and design experiments to test them. He was not trained to consider the nature of God. And yet, his scientific research led him directly to the discovery of God's existence in intelligent evolution and everyday life.Scientifically rigorous and spiritually reassuring, this eye-opening book is a wake-up call for anyone who wonders about life's true meaning and who longs to believe in the existence of a universal intelligence.

    But as animals can only be spied on by getting quite close Heinrich adopts ravens, thereby becoming a "raven father," as well as observing them in their natural habitat, studying their daily routines, and in the process painting a vivid picture of the world as lived by the ravens. At the heart of this book are Heinrich's love and respect for these complex and engaging creatures, and through his keen observation andanalysis, we become their intimates too.Throughout history there has existed an extraordinary relationship between humans and ravens. Ravens, like early humans, are scavengers on the kills of great carnivores. As scavengers, ravens were associated with hunters they found in the north: wolves and, later, men. The trinity of wolf, man, and raven in the hunt is an extremely ancient one. In considering the appeal of the raven, Bernd Heinrich suspects that a meeting of the minds might reside in that hunting trinity.Heinrich's passion for ravens has led him around the world in his research. Mind of the Raven takes you on an exotic journey--from New England to Germany, Montana to Baffin Island in the high Arctic--offering dazzling accounts of how science works in the field, filtered through the eyes of a passionate observer of nature.Heinrich has a true gift; through his stories, his beautiful writing, illustrations, and photography, the ravens come alive. Each new discovery and insight into their behavior is thrilling to read. just as the title promises, the reader is given a rare glimpse into the mind of these wonderful creatures.Following the dictum of Leonardo da Vinci--"It is not enough to believe what you see. YOU Must also understand what you see"--Bernd Heinrich enables us to see the natural world through the eyes of a scientist. At once lyrical and scientific, Mind of the Raven is bound to be a modern classic.
