Driving Force
The Natural Magic of Magnets
James D. Livingston
Harvard University Press, 1996

Driving Force unfolds the long and colorful history of magnets: how they guided (or misguided) Columbus; mesmerized eighteenth-century Paris but failed to fool Benjamin Franklin; lifted AC power over its rival, DC, despite all the animals, one human among them, executed along the way; led Einstein to the theory of relativity; helped defeat Hitler's U-boats; inspired writers from Plato to Dave Barry. In a way that will delight and instruct even the nonmathematical among us, James Livingston shows us how scientists today are creating magnets and superconductors that can levitate high-speed trains, produce images of our internal organs, steer high-energy particles in giant accelerators, and--last but not least--heat our morning coffee.

From the "new" science of materials to everyday technology, Driving Force makes the workings of magnets a matter of practical wonder. The book will inform and entertain technical and nontechnical readers alike and will give them a clearer sense of the force behind so much of the working world.

Rising Force
The Magic of Magnetic Levitation
James D. Livingston
Harvard University Press, 2011

From Peter Pan to Harry Potter, from David Copperfield to levitating toys, there is magic in conquering gravity. In this first-ever popular introduction to “maglev”— the use of magnetic forces to overcome gravity and friction—James D. Livingston takes lay readers on a journey of discovery, from basic concepts to today’s most thrilling applications.

The tour begins with examples of our historical fascination with levitation, both real and fake. At the next stop, Livingston introduces readers to the components of maglev: gravitational and magnetic forces in the universe, force fields, diamagnetism and stabilization, superdiamagnetism and supercurrents, maglev nanotechnology, and more. He explores the development of the superconductors that are making large-scale levitation devices possible, and the use of magnetic bearings in products ranging from implanted blood pumps to wind turbines, integrated circuit fabrication, and centrifuges to enrich uranium. In the last chapters, we arrive at the science behind maglev transportation systems, such as Chinese trains that travel 250 miles per hour without touching the tracks.

Packed with fascinating anecdotes about the colorful personalities who have “fought friction by fighting gravity,” the book maintains accuracy throughout while it entertains and informs technical and nontechnical readers alike. With so many new applications for magnetic levitation on the horizon, Rising Force is sure to retain its own magic for years to come.

A Very Dangerous Woman
Martha Wright and Women's Rights
Sharon H. Penney
University of Massachusetts Press, 2004
A very dangerous woman is what Martha Coffin Wright's conservative neighbors considered her, because of her work in the women's rights and abolition movements. In 1848, Wright and her older sister Lucretia Mott were among the five brave women who organized the historic Seneca Falls Women's Rights Convention. Wright remained a prominent figure in the women's movement until her death in 1875 at age sixty-eight, when she was president of the National Woman Suffrage Association. At age twenty-six, she attended the 1833 founding of the American Anti-Slavery Society and later presided over numerous antislavery meetings, including two in 1861 that were disrupted by angry antiabolitionist mobs. Active in the Underground Railroad, she sheltered fugitive slaves and was a close friend and supporter of Harriet Tubman.

In telling Wright's story, the authors make good use of her lively letters to her family, friends, and colleagues, including Susan B. Anthony and Elizabeth Cady Stanton. These letters reveal Wright's engaging wit and offer an insider's view of nineteenth-century reform and family life. Her correspondence with slaveholding relatives in the South grew increasingly contentious with the approach of the Civil War. One nephew became a hero of the Confederacy with his exploits at the Battle of Fredericksburg, and her son in the Union artillery was seriously wounded at Gettysburg while repelling Pickett's Charge.

Wright's life never lacked for drama. She survived a shipwreck, spent time at a frontier fort, experienced the trauma of the deaths of a fiancé, her first husband, and three of her seven children, and navigated intense conflicts within the women's rights and abolition movements. Throughout her tumultuous career, she drew on a reservoir of humor to promote her ideas and overcome the many challenges she faced. This accessible biography, written with the general reader in mind, does justice to her remarkable life.
