Leonardo Cook, practicing psychiatrist, is experiencing a delicate emotional phase. His wife has left him for another man, his patients are boring and he's feeling somewhat guilty about his relationship with his girlfriend, a Starbucks employee half his age. And he may be on the verge of another nervous breakdown. When Leonardo is called upon by a friend to talk a tech genius out of making public a secret new innovation—and the tech genius ends up jumping out of the window—Leonardo's life takes flight on a roller-coaster of disaster. Making a darkly hilarious debut, Jonathan Canter gleefully builds a small Massachusetts town filled with the interrelated lives of fantastically neurotic characters—and at their center, poor, "lucky" Leonardo. Fast-paced and laugh-out-loud funny, Lucky Leonardo is not to be missed.

Leonardo’s Science Workshop leads children on an interactive adventure through key science concepts by following the multidisciplinary approach of the Renaissance period polymath Leonardo da Vinci: experimenting, creating projects, and exploring how art intersects with science and nature. Photos of Leonardo’s own notebooks, paintings, and drawings provide visual inspiration. More than 500 years ago, Leonardo knew that the fields of science, technology, engineering, art, and mathematics (STEAM) are all connected. The insatiably curious Leonardo examined not just the outer appearance of his art subjects, but the science that explained them. He began his studies as a painter, but his curiosity, diligence, and genius made him also a master sculptor, architect, designer, scientist, engineer, and inventor. The Leonardo’s Workshop series shares this spirit of multidisciplinary inquiry with children through accessible, engaging explanations and hands-on learning. This fascinating book harnesses children’s innate curiosity to explore some of Leonardo’s favorite subjects, including flight, motion, technology design, perspective, and astronomy. After each topic is explained with concepts from physics, chemistry, math, and engineering, kids can experience the principles first-hand with step-by-step STEAM projects. They will explore: The physics of flight by observing birds and experimenting with paper airplane designs The science of motion by building a windup dragonfly Gravitational acceleration with water balloons The movement of electrons by making cereal “dance” Technology design by making paper and fabric using recycled material Scientific perspective by drawing a 3D illusion Insight from other great thinkers—such as Galileo Galilei, James Clerk Maxwell, and Sir Isaac Newton—are woven into the lessons throughout. Introduce vital STEAM skills through visually rich, hands-on learning with Leonardo’s Science Workshop.

Leonardo is only in his early twenties and doesn't expect much from life. His father became an alcoholic after his mother died, and now Leonardo has to work two jobs to pay the family bills, as well as some of his father's debts in nightclubs. He's tired of this life, full of hard work to get his father out of trouble, which has cost him four jobs. Leonardo went home tired and, as soon as he opened the door, he was shocked to find three other men in the room, in addition to his injured father, one of them pointing a gun at his father's head. The man turned his head to look at him coldly, examining him from head to toe. Leonardo only felt chills down his spine. "Your dear father owes me some money. I gave him a deadline, but he didn't meet it, and I came to collect the debt." "How much?" "Twenty-eight thousand dollars." "What?" He was later cornered by Frank Gold, the mobster, who seemed to want something more than money...

A hilarious satire about college life and high class manners, this is a classic of postwar English literature. Regarded by many as the finest, and funniest, comic novel of the twentieth century, Lucky Jim remains as trenchant, withering, and eloquently misanthropic as when it first scandalized readers in 1954. This is the story of Jim Dixon, a hapless lecturer in medieval history at a provincial university who knows better than most that “there was no end to the ways in which nice things are nicer than nasty ones.” Amis’s scabrous debut leads the reader through a gallery of emphatically English bores, cranks, frauds, and neurotics, with each of whom Dixon must contend in one way or another in order to hold on to his cushy academic perch and win the girl of his fancy. More than just a merciless satire of cloistered college life and stuffy post-war manners, Lucky Jim is an attack on the forces of boredom, whatever form they may take, and a work of art that at once distills and extends an entire tradition of English comic writing, from Fielding and Dickens through Wodehouse and Waugh. As Christopher Hitchens has written, “if you can picture Bertie or Jeeves being capable of actual malice, and simultaneously imagine Evelyn Waugh forgetting about original sin, you have the combination of innocence and experience that makes this short romp so imperishable.”

An exploration of the effect our celebrity-dominated culture has on our ideas of living the good life What would happen if an average Joe tried out for American Idol, underwent a professional makeover, endured Gwyneth Paltrow’s “Clean Cleanse,” and followed the outrageous rituals of the rich and famous? Health law policy researcher Timothy Caulfield finds out in this thoroughly unique, engaging, and provocative book about celebrity culture and its iron grip on today’s society. Over the past decade, our perceptions of beauty, health, success, and happiness have become increasingly framed by a popular culture steeped in celebrity influence and ever more disconnected from reality. This isn't just a hyperbolic assertion. Research tells us that our health decisions and goals are influenced by both celebrity culture and celebrity endorsements, our children's ambitions are now overwhelmingly governed by the fantasy of fame, and the ideals of beauty and success are mediated through a celebrity-dominated worldview. But while much has been written about the cause of our obsession with the rich and famous, Caulfield argues that not enough has been done to debunk celebrity messages and promises about health, diet, beauty, or the secret to happiness. From the obvious dangers, to body image of super-thin models and actors, or Gwyneth Paltrow’s enthusiastic endorsement of a gluten free-diet for almost everyone, or Jenny McCarthy’s ill-informed claims of the risks associated with vaccines, celebrity opinions have the power to dominate our conversations and outlooks on our lives and ourselves. As marketing and social media bring celebrities and their admirers ever closer, celebrity status and lifestyle has become a seemingly more realistic and obtainable goal. Being famous has become the main ambition of an increasing number of average citizens, above being kind, successful, or loved. The celebrity brand is at once the most desired state of being (modern day royalty!) and one of the most socially problematic. Caulfield provides an entertaining look into the celebrity world, including vivid accounts of his own experiences trying out for American Idol, having his skin resurfaced, and doing the cleanse; interviews with actual celebrities; thought-provoking facts, and a practical and evidence-based reality check on our own celebrity ambitions.
