LEGO Chain Reactions is packed full of ideas, instructions, and inspiration for 10 LEGO machines that spin, swing, pivot, roll, lift, and drop. Each machine alone is awesome, but put them together and you get incredible chain reactions. Then, combine the machines in any order you like to create your own chain reactions. Our team of experts worked with educators and 11-year-olds to invent the machines, then wrote a book that teaches the skills (and some of the physics behind the fun) kids need to create their own amazing chain reaction machines.Our book includes 33 special LEGO elements that combine with basic bricks from your collection to make your machines go. But don’t worry that you won’t have the right bricks; we worked with the folks at LEGO to make sure you’ll need only the most common bricks, and that there are plenty of substitutes. The result is a chain reaction of fun, as one thing leads to another and another and another.Comes with: 78 page book, 33 LEGO elements, 6 LEGO balls, 6 feet of string, 8 paper ramps, 2 paper pop-up signs, 1 paper funnel ramp, 1 paper flag, 1 paper bucket, 1 platform
Despite the excitement around "data science," "big data," and "analytics," the ambiguity of these terms has led to poor communication between data scientists and organizations seeking their help. In this report, authors Harlan Harris, Sean Murphy, and Marck Vaisman examine their survey of several hundred data science practitioners in mid-2012, when they asked respondents how they viewed their skills, careers, and experiences with prospective employers. The results are striking.Based on the survey data, the authors found that data scientists today can be clustered into four subgroups, each with a different mix of skillsets. Their purpose is to identify a new, more precise vocabulary for data science roles, teams, and career paths.This report describes:Four data scientist clusters: Data Businesspeople, Data Creatives, Data Developers, and Data ResearchersCases in miscommunication between data scientists and organizations looking to hireWhy "T-shaped" data scientists have an advantage in breadth and depth of skillsHow organizations can apply the survey results to identify, train, integrate, team up, and promote data scientists
"The most powerful book of its kind I've ever read.... Extraordinary powers of observation, generalization, and depth."―Oliver Sacks, author of The Man Who Mistook His Wife For a Hat Winner of the Columbia University Lionel Trilling Award. Robert Murphy was in the prime of his career as an anthropologist when he felt the first symptom of a malady that would ultimately take him on an odyssey stranger than any field trip to the Amazon: a tumor of the spinal cord that progressed slowly and irreversibly into quadriplegia. In this gripping account, Murphy explores society's fears, myths, and misunderstandings about disability, and the damage they inflict. He reports how paralysis―like all disabilities―assaults people's identity, social standing, and ties with others, while at the same time making the love of life burn even more fiercely.
Described as "a harmonious human multitude," Ben Franklin's life and careers were so varied and successful that he remains, even today, the epitome of the self-made man. Born into a humble tradesman's family, this adaptable genius rose to become an architect of the world's first democracy, a leading light in Enlightenment science, and a major creator of what has come to be known as the American character. Journalist, musician, politician, scientist, humorist, inventor, civic leader, printer, writer, publisher, businessman, founding father, philosopher—a genius in all fields and a bit of a magician in some.Volume 3 begins in the year 1748, when Franklin was known in Pennsylvania as clerk of the Pennsylvania Assembly and in the Middle Colonies as the printer and editor of Poor Richard's Almanac and the Pennsylvania Gazette, the best-known colonial publications. By the middle of 1757, where this volume leaves off, he had become famous in Pennsylvania as a public-spirited citizen and soldier in the conflicts of the Seven Years' War; well known throughout America as a writer, politician, and the most important theorist and patriot of the American empire; and renowned in the western world as a natural philosopher. This volume tells the story of that transformation.
In volume one of this landmark study, focusing on developments up to 1940, Margaret Rossiter describes the activities and personalities of the numerous women scientists―astronomers, chemists, biologists, and psychologists―who overcame extraordinary obstacles to contribute to the growth of American science. This remarkable history recounts women's efforts to establish themselves as members of the scientific community and examines the forces that inhibited their active and visible participation in the sciences.
The Age of Wonder is a colorful and utterly absorbing history of the men and women whose discoveries and inventions at the end of the eighteenth century gave birth to the Romantic Age of Science. When young Joseph Banks stepped onto a Tahitian beach in 1769, he hoped to discover Paradise. Inspired by the scientific ferment sweeping through Britain, the botanist had sailed with Captain Cook in search of new worlds. Other voyages of discovery—astronomical, chemical, poetical, philosophical—swiftly follow in Richard Holmes's thrilling evocation of the second scientific revolution. Through the lives of William Herschel and his sister Caroline, who forever changed the public conception of the solar system; of Humphry Davy, whose near-suicidal gas experiments revolutionized chemistry; and of the great Romantic writers, from Mary Shelley to Coleridge and Keats, who were inspired by the scientific breakthroughs of their day, Holmes brings to life the era in which we first realized both the awe-inspiring and the frightening possibilities of science—an era whose consequences are with us still.
