    to work to talk to teen boys about the science and pressures of growing up male in today's world. A must-have book for all teenage boys!Why does my voice crack like that? What should I eat to build muscle? How do I talk to someone I have a crush on? What do I do if someone calls me names or bullies me?Growing from a boy to a man is no easy task. Bodies are changing, social circles are evolving, hair is appearing in places it never was before -- and on top of it all, there's the ever-present pressure to conform to the typical idea of what it means to be "manly" and masculine. But it's easier to do if you're armed with facts.Using personal anecdotes as an overly observant mother of two boys and plenty of scientific information from her life as a neuroscientist, Mayim Bialik, PhD, star of The Big Bang Theory, talks directly to teen boys about what it means to grow from a boy to a man biologically, psychologically, and sociologically. Using the same cool, fun, and friendly tone that she took in Girling Up, Mayim takes boys--and their parents!--through the challenges and triumphs of Boying Up today.In six sections (How Boys Bodies Work; How Boys Grow; How Boys Learn; How Boys Cope; How Boys Love; and How Boys Make a Difference), she takes a look at what it means for boys to come of age in today's world, how can they take control of their paths, and what can they do to help shape the types of futures they want for themselves.Praise for Boying Up "A matter-of-fact mirror that reflects reality and respect, not bewildered embarrassment." --Kirkus Reviews"Boying Up hits all the hot spots and should be included in tween and teen library collections." --VOYA

    In fact, getting sick and dying can be a big, ugly mess-especially before the modern medical care that we all enjoy today. How They Croaked relays all the gory details of how nineteen world figures gave up the ghost. For example:It is believed that Henry VIII's remains exploded within his coffin while lying in state. Doctors "treated" George Washington by draining almost 80 ounces of blood before he finally kicked the bucket. Right before Beethoven wrote his last notes, doctors drilled a hole in his stomach without any pain medication.Readers will be interested well past the final curtain, and feel lucky to live in a world with painkillers, X-rays, soap, and 911.

    Browne and his love of precepts. Simply put, precepts are principles to live by, and Mr. Browne has compiled 365 of them—one for each day of the year—drawn from popular songs to children’s books to inscriptions on Egyptian tombstones to fortune cookies. His selections celebrate kindness, hopefulness, the goodness of human beings, the strength of people’s hearts, and the power of people’s wills. Interspersed with the precepts are letters and emails from characters who appeared in Wonder. Readers hear from Summer, Jack, Charlotte, Julian, and Amos.   There’s something for everyone here, with words of wisdom from such noteworthy people as Anne Frank, Martin Luther King Jr., Confucius, Goethe, Sappho—and over 100 readers of Wonder who sent R. J. Palacio their own precepts.

    Phineas, a railroad construction foreman, was blasting rock near Cavendish, Vermont, in 1848 when a thirteen-pound iron rod was shot through his brain. Miraculously, he survived to live another eleven years and become a textbook case in brain science.At the time, Phineas Gage seemed to completely recover from his accident. He could walk, talk, work, and travel, but he was changed. Gage "was no longer Gage," said his Vermont doctor, meaning that the old Phineas was dependable and well liked, and the new Phineas was crude and unpredictable.His case astonished doctors in his day and still fascinates doctors today. What happened and what didn’t happen inside the brain of Phineas Gage will tell you a lot about how your brain works and how you act human.

    Thorough in its coverage of basic theory, from the lever and inclined plane to internal combustion engines and power trains, it requires nothing more than an understanding of the most elementary mathematics. Beginning with the simplest of machines — the lever — the text proceeds to discussions of the block and tackle (pulleys and hoists), wheel and axle, the inclined plane and the wedge, the screw, and different types of gears (simple, spur, bevel, herringbone, spiral, worm, etc.). A chapter on the concept of work discusses the measurement of work, friction, and efficiency; this is followed by investigations of power, force, and pressure, with explanations of the uses of scales, balances, gauges, and barometers. The fundamentals of hydrostatic and hydraulic machines (such as the hydraulic braking system and the hydraulic press) are discussed in detail. The remaining chapters cover machine elements (bearings and springs), basic mechanisms (gear differential, couplings, cams, clutches), the internal combustion engine and power trains (including explanations of various transmission systems — synchromesh, auxiliary, etc.). Every concept is clearly defined, and discussions always build easily from elementary theory to specific applications familiar to anyone with the slightest interest in mechanics. Important concepts, machine components, and techniques are clearly illustrated in more than 200 diagrams, drawings, and cross-sections that reveal inner workings — all of these help to clarify even further an already clear and well-organized presentation. Although it was originally designed for use in U.S. Naval Training Schools, this book can be used to great advantage as a basic text in mechanical engineering in standard technical schools, and it will be immensely valuable even to lay readers who desire a basic knowledge of mechanics.
