    High school science teacher Tom Robinson shows you how to expand your scientific horizons-from biology to chemistry to physics to outer space. You'll discover answers to questions like: Is it possible to blow up a balloon without actually blowing into it? What is inside coins? Can a magnet ever be "turned off"? Do toilets always flush in the same direction? Can a swimming pool be cleaned with just the breath of one person? You won't want to wait for a rainy day or your school's science fair to test these cool experiments for yourself! Tom Robinson teaches high school science and math and has coauthored an online advance placement physics course.

    Millipedes do it. Dinosaurs did it. You do it: I do it. Octopuses don't (and nor do octopi). Spiders might do it: more research is needed. Birds don't do it, but they could if they wanted to. Herrings do it to communicate with each other. At the beginning of 2017, an innocent question on twitter about snakes formed the hashtag #doesitfart and spread pungently across the internet - and major newspapers - as dozens of experts weighed in on which animals do and don't fart, and if they do, how much, how often, what it's made of, what it smells like, and what it's for. Does it Fart? is the result: the fully authoritative, fully illustrated guide to animal flatulence, covering the habits of 80 animals in more detail than you ever knew you needed. What foods make hyena farts smell especially bad? What is a fossa, and does it fart? Why do clams vomit but not fart? What is a fart, anyway? With contributions from dozens of biologists, Does it Fart? is a book that will allow you to shift the blame onto all kinds of unlikely animals for years to come.

    Brian Greene, one of the world's leading string theorists, peels away the layers of mystery surrounding string theory to reveal a universe that consists of eleven dimensions, where the fabric of space tears and repairs itself, and all matter—from the smallest quarks to the most gargantuan supernovas—is generated by the vibrations of microscopically tiny loops of energy.Today physicists and mathematicians throughout the world are feverishly working on one of the most ambitious theories ever proposed: superstring theory. String theory, as it is often called, is the key to the Unified Field Theory that eluded Einstein for more than thirty years. Finally, the century-old antagonism between the large and the small-General Relativity and Quantum Theory-is resolved. String theory proclaims that all of the wondrous happenings in the universe, from the frantic dancing of subatomic quarks to the majestic swirling of heavenly galaxies, are reflections of one grand physical principle and manifestations of one single entity: microscopically tiny vibrating loops of energy, a billionth of a billionth the size of an atom. In this brilliantly articulated and refreshingly clear book, Greene relates the scientific story and the human struggle behind twentieth-century physics' search for a theory of everything.Through the masterful use of metaphor and analogy, The Elegant Universe makes some of the most sophisticated concepts ever contemplated viscerally accessible and thoroughly entertaining, bringing us closer than ever to understanding how the universe works.

    When she meets Charles Babbage, the inventor of the first mechanical computer, Ada understands the machine better than anyone else and writes the world's first computer program in order to demonstrate its capabilities.

    Presents an introduction to Shakespeare's greatest plays including Hamlet Othello, As You Like It, The Taming of the Shrew, The Tempest and Pericles.

       This non-fiction picture book explores time and how we think about it in a different way - as a series of events in the natural world (some of them directly observable, others not) that take place in a given unit of time. Steve Jenkins' extraordinary illustrations will accompany this engaging look at time.

    Just about everyone has at least heard of Albert Einstein's formulation of 1905, which came into the world as something of an afterthought. But far fewer can explain his insightful linkage of energy to mass. David Bodanis offers an easily grasped gloss on the equation. Mass, he writes, "is simply the ultimate type of condensed or concentrated energy," whereas energy "is what billows out as an alternate form of mass under the right circumstances." Just what those circumstances are occupies much of Bodanis's book, which pays homage to Einstein and, just as important, to predecessors such as Maxwell, Faraday, and Lavoisier, who are not as well known as Einstein today. Balancing writerly energy and scholarly weight, Bodanis offers a primer in modern physics and cosmology, explaining that the universe today is an expression of mass that will, in some vastly distant future, one day slide back to the energy side of the equation, replacing the "dominion of matter" with "a great stillness"--a vision that is at once lovely and profoundly frightening. Without sliding into easy psychobiography, Bodanis explores other circumstances as well; namely, Einstein's background and character, which combined with a sterling intelligence to afford him an idiosyncratic view of the way things work--a view that would change the world. --Gregory McNamee

    It had an illustration that captivated him–a diagram showing Earth’s interior as it would look if you cut into it with a large knife and removed about a quarter of its bulk. The idea of lots of startled cars and people falling off the edge of that sudden cliff (and 4,000 miles is a pretty long way to fall) was what grabbed him in the beginning, but gradually his attention turned to what the picture was trying to teach him: namely that Earth’s interior is made up of several different layers of materials, and at the very centre is a glowing sphere of iron and nickel, as hot as the Sun’s surface, according to the caption. And he very clearly remembers thinking: “How do they know that?”Bill’s storytelling skill makes the “How?” and, just as importantly, the “Who?” of scientific discovery entertaining and accessible for all ages. He covers the wonder and mystery of time and space, the frequently bizarre and often obsessive scientists and the methods they used, and the mind-boggling fact that, somehow, the universe exists and against all odds, life came to be on this wondrous planet we call home.

    Brought to life with lyrical text by award-winning author Donna Jo Napoli and stunning artwork by award-winning illustrator Christina Balit, the tales of gods and goddesses such as Zeus, Aphrodite, Apollo, and Athena and heroes and monsters such as Helen of Troy, Perseus, and Medusa will fascinate and engage children’s imaginations.   National Geographic completes the book with embellishments of each story: sidebars for each god, goddess, hero, and monster link the myths to constellations, geography, history, and culture to help young readers connect the stories to real life events, people, and places. A family tree and a “cast of characters” profile page help make relationships between the characters clear, and a mapping feature adds to the fun and fascination. Resource notes and ample back matter directing readers to more information round out this luminous book.

    In this fun and accessible guide, McKellar—dubbed a “math superstar” by The New York Times—gives girls and their parents the tools they need to master the math concepts that confuse middle-schoolers most, including fractions, percentages, pre-algebra, and more. The book features hip, real-world examples, step-by-step instruction, and engaging stories of Danica's own childhood struggles in math (and stardom). In addition, borrowing from the style of today's teen magazines, it even includes a Math Horoscope section, Math Personality Quizzes, and Real-Life Testimonials—ultimately revealing why math is easier and cooler than readers think.

    Bennett's bestselling The Book of Virtues is an inspiring anthology that helps children understand and develop moral character—and helps parents teach it to them.Responsibility. Courage. Compassion. Honesty. Friendship. Persistence. Faith. Everyone recognizes these traits as essentials of good character.

And the best places to find them are in great works of literature and exemplary stories from history. William J. Bennett has collected hundreds of stories in The Book of Virtues. From the Bible to American history, from Greek mythology to English poetry, from fairy tales to modern fiction, these stories are a rich mine of moral literacy, a reliable moral reference point that will help anchor our children and ourselves in our culture, our history, and our traditions—the sources of the ideals by which we wish to live our lives. Complete with instructive introductions and notes, The Book of Virtues is a book the whole family can read and enjoy—and learn from—together.
