Entender a Física do futebol provavelmente não vai fazer ninguém jogar melhor, mas com certeza vai ajudar a compreender um pouco mais esse jogo fascinante. E para quem quer compreender as leis do movimento, estudar a Física do futebol é a maneira mais descontraída de fazê-lo. Este é o objetivo desta obra: mostrar para os boleiros e curiosos da Física, a Física que há no futebol.
O livro não só ensina Física, mas também as próprias regras do futebol e tudo o que nele acontece relacionado à Mecânica. Os conceitos de Mecânica são descritos de forma a cobrir todo o conteúdo normalmente abrangido no currículo de Física do primeiro ano do ensino médio.
A presente obra foi escrita de maneira a descrever em mais detalhes o porquê de certas coisas na Mecânica. Fórmulas matemáticas são utilizadas, mas sempre procuramos mostrar a motivação que existe por detrás delas. Acreditamos que o livro possa ser utilizado de maneira quase autodidata, pela forma como foi desenvolvido.
Circuitos de Corrente Alternada apresenta os tópicos fundamentais da teoria nesta área, como medição de grandezas elétricas; formas de onda; características elétricas de resistores, indutores e capacitores; circuitos trifásicos; transformadores; motores; potência em circuitos; instalações elétricas e segurança.
Além da parte teórica, a obra apresenta problemas resolvidos, exercícios propostos, leituras recomendadas e vídeos que mostram a teoria na prática.
Reunindo em um único volume tópicos normalmente encontrados em vários livros, Circuitos de Corrente Alternada fornece uma referência básica para estudantes de Engenharia Elétrica, Mecânica e Civil, assim como alunos de colégios técnicos e cursos de Eletrotécnica, entre outros.
Com ilustrações criativas e texto lúcido e bem-humorado, Hawking desvenda desde os mistérios da física de partículas até a dinâmica que movimenta centenas de milhões de galáxias por todo o universo. Para o iniciado, Uma breve história do tempo é uma bela representação de conceitos complexos; para o leigo, é um vislumbre dos segredos mais profundos da criação.
Now translated into thirty languages, Einstein’s Dreams has inspired playwrights, dancers, musicians, and painters all over the world. In poetic vignettes, it explores the connections between science and art, the process of creativity, and ultimately the fragility of human existence.
“In this slight volume, Lightman looks toward the universe and captures aspects of it in a series of beautifully written essays, each offering a glimpse at the whole from a different perspective: here time, there symmetry, not least God. It is a meditation by a remarkable humanist-physicist, a book worth reading by anyone entranced by big ideas grounded in the physical world.”
—Peter L. Galison, Joseph Pellegrino University Professor, Harvard University

Bennett always knew he would live a life of science. From the homemade rockets and experiments of his childhood to the complex equations he solved as a professor of physics, his vision has transformed the uncertainty and frailty of life into an order and beauty that he inhabits with deep satisfaction. But his vision betrays him, revealing a profound incompleteness, an inadequacy to confront the contradictions his life: the black maid who raises him and loves him but cannot welcome him into her own house, the mentally absent father who wishes he’d died a hero in World War II, the self-destructive wife who invites Bennett’s cruelty. As Bennett struggles between reason and intuition, he slowly learns to allow the imperfections of daily life—the chaos he has worked so hard to control—to broaden his understanding of the world and his place in it.
Written with lyrical sparseness, hilarity mixed with sadness, the story of Bennett’s struggle becomes both a beautifully rendered portrait of the emotional life of a scientist and a resonant tale of the disillusionment that haunts us all.

So begins Alan Lightman’s playful and profound new novel, Mr g, the story of Creation as told by God. Barraged by the constant advisements and bickerings of Aunt Penelope and Uncle Deva, who live with their nephew in the shimmering Void, Mr g proceeds to create time, space, and matter. Then come stars, planets, animate matter, consciousness, and, finally, intelligent beings with moral dilemmas. Mr g is all powerful but not all knowing and does much of his invention by trial and error.
Even the best-laid plans can go awry, and Mr g discovers that with his creation of space and time come some unforeseen consequences—especially in the form of the mysterious Belhor, a clever and devious rival. An intellectual equal to Mr g, Belhor delights in provoking him: Belhor demands an explanation for the inexplicable, requests that the newly created intelligent creatures not be subject to rational laws, and maintains the necessity of evil. As Mr g watches his favorite universe grow into maturity, he begins to understand how the act of creation can change himself, the Creator.
With echoes of Calvino, Rushdie, and Saramago, combining science, theology, and moral philosophy, Mr g is a stunningly imaginative work that celebrates the tragic and joyous nature of existence on the grandest possible scale.
Alan Lightman’s grandfather M.A. Lightman was the family’s undisputed patriarch: it was his movie theater empire that catapulted the Lightmans to prominence in the South, his fearless success that both galvanized and paralyzed his children and grandchildren. In this moving, impressionistic memoir, the author chronicles his return to Memphis in an attempt to understand the origins he so eagerly left behind forty years earlier. As aging uncles and aunts begin telling family stories, Lightman rediscovers his southern roots and slowly recognizes the errors in his perceptions of both his grandfather and his father, who was himself crushed by M.A. The result is an unforgettable family saga that extends from 1880 to the present, set against a throbbing century of Memphis—the rhythm and blues, the barbecue and pecan pie, the segregated society—and including personal encounters with Elvis, Martin Luther King Jr., and E. H. “Boss” Crump. At the heart of it all is a family haunted by the memory of its domineering patriarch and the author’s struggle to understand his conflicted loyalties.
(With black-and-white illustrations throughout.)

In these brilliant essays, Lightman explores the emotional life of science, the power of imagination, the creative moment, and the alternate ways in which scientists and humanists think about the world. Along the way, he provides in-depth portraits of some of the great geniuses of our time, including Albert Einstein, Richard Feynman, Edward Teller, and astronomer Vera Rubin. Thoughtful, beautifully written, and wonderfully original, A Sense of the Mysterious confirms Alan Lightman's unique position at the crossroads of science and art.
Bill’s memory returns, but a strange numbness afflicts him. As he attempts to find a diagnosis for his deteriorating illness, he descends into a nightmarish tangle of inconclusive results, his company’s manic frenzy, and his family’s disbelief. Ultimately, Bill discovers that he is fighting not just for his body but also for his soul.
