Kirkus Star Junior Library Guild Gold Selection Mark Weston’s high-interest story and Rebecca Evans’s colorful graphics make scientific discovery the coolest thing this side of Jupiter. More than two centuries before Einstein, using a crude telescope and a mechanical timepiece, Danish astronomer Ole Romer measured the speed of light with astounding accuracy. How was he able to do this when most scientists didn’t even believe that light traveled? Like many paradigm-shattering discoveries, Romer’s was accidental. Night after night he was timing the disappearance and reappearance of Jupiter’s moon Io behind the huge, distant planet. Eventually he realized that the discrepancies in his measurements could have only one explanation: Light had a speed, and it took longer to reach Earth when Earth was farther from Jupiter. All he needed then to calculate light’s speed was some fancy geometry.

A fast-growing legal system and economy in medieval and early modern Rome saw a rapid increase in the need for written documents. Brokers of Public Trust examines the emergence of the modern notarial profession—free market scribes responsible for producing original legal documents and their copies. Notarial acts often go unnoticed, but they are essential to understanding the history of writing practices and attitudes toward official documentation. Based on new archival research, Brokers of Public Trust focuses on the government officials, notaries, and consumers who regulated, wrote, and purchased notarial documents in Rome between the 14th and 18th centuries. Historian Laurie Nussdorfer chronicles the training of professional notaries and the construction of public archives, explaining why notarial documents exist, who made them, and how they came to be regarded as authoritative evidence. In doing so, Nussdorfer describes a profession of crucial importance to the people and government of the time, as well as to scholars who turn to notarial documents as invaluable and irreplaceable historical sources. This magisterial new work brings fresh insight into the essential functions of early modern Roman society and the development of the modern state.

This book presents the life and personality, the scientific and philosophical work of Ludwig Boltzmann, one of the great scientists who marked the passage from 19th- to 20th-Century physics. His rich and tragic life, ending by suicide at the age of 62, is described in detail. A substantial part of the book is devoted to discussing his scientific and philosophical ideas and placing them in the context of the second half of the 19th century. The fact that Boltzmann was the man who did most to establish that there is a microscopic, atomic structure underlying macroscopic bodies is documented, as is Boltzmann's influence on modern physics, especially through the work of Planck on light quanta and of Einstein on Brownian motion. Boltzmann was the centre of a scientific upheaval, and he has been proved right on many crucial issues. He anticipated Kuhn's theory of scientific revolutions and proposed a theory of knowledge based on Darwin. His basic results, when properly understood, can also be stated as mathematical theorems. Some of these have been proved: others are still at the level of likely but unproven conjectures. The main text of this biography is written almost entirely without equations. Mathematical appendices deepen knowledge of some technical aspects of the subject.

This beautifully produced volume is the first to survey the Metropolitan Museum's world-renowned collection of European furniture. One hundred and three superb examples from the Museum's vast holdings are featured. They originated in workshops in England, France, Germany, Italy, the Netherlands, Austria, Russia, or Spain and date from the Renaissance to the late nineteenth century. A number of them belonged to such important historical figures as Pope Urban VIII, Louis XIV, Madame de Pompadour, and Napoleon. The selection includes chairs, tables, beds, cabinets, commodes, settees and sofas, bookcases and standing shelves, desks, fire screens, athéniennes, coffers, chests, mirrors and frames, showcases, and lighting equipment. There is also one purely decorative piece, a superb vase made for a Russian noble family who, according to one awestruck viewer, "owned all the malachite mines in the world." The makers of some of the objects are unknown, but most of the pieces can be identified by label, documentation, or style as the work of an outstanding European designer-craftsman, such as André-Charles Boulle, Thomas Chippendale, David Roentgen, or Karl Friedrich Schinkel.

"The creation of the United States of America is the greatest of all human adventures," begins Paul Johnson's remarkable new American history. "No other national story holds such tremendous lessons, for the American people themselves and for the rest of mankind." Johnson's history is a reinterpretation of American history from the first settlements to the Clinton administration. It covers every aspect of U.S. history--politics; business and economics; art, literature and science; society and customs; complex traditions and religious beliefs. The story is told in terms of the men and women who shaped and led the nation and the ordinary people who collectively created its unique character. Wherever possible, letters, diaries, and recorded conversations are used to ensure a sense of actuality. "The book has new and often trenchant things to say about every aspect and period of America's past," says Johnson, "and I do not seek, as some historians do, to conceal my opinions." Johnson's history presents John Winthrop, Roger Williams, Anne Hutchinson, Cotton Mather, Franklin, Tom Paine, Washington, Adams, Jefferson, Hamilton, and Madison from a fresh perspective. It emphasizes the role of religion in American history and how early America was linked to England's history and culture and includes incisive portraits of Andrew Jackson, Chief Justice Marshall, Clay, Lincoln, and Jefferson Davis. Johnson shows how Grover Cleveland and Teddy Roosevelt ushered in the age of big business and industry and how Woodrow Wilson revolutionized the government's role. He offers new views of Harding, Coolidge, and Hoover and of Franklin Roosevelt's New Deal and his role as commander in chief during World War II. An examination of the unforeseen greatness of Harry Truman and reassessments of Eisenhower, Kennedy, Johnson, Nixon, Reagan, and Bush follow. "Compulsively readable," said Foreign Affairs of Johnson's unique narrative skills and sharp profiles of people. This is an in-depth portrait of a great people, from their fragile origins through their struggles for independence and nationhood, their heroic efforts and sacrifices to deal with the `organic sin' of slavery and the preservation of the Union to its explosive economic growth and emergence as a world power and its sole superpower. Johnson discusses such contemporary topics as the politics of racism, education, Vietnam, the power of the press, political correctness, the growth of litigation, and the rising influence of women. He sees Americans as a problem-solving people and the story of America as "essentially one of difficulties being overcome by intelligence and skill, by faith and strength of purpose, by courage and persistence...Looking back on its past, and forward to its future, the auguries are that it will not disappoint humanity." This challenging narrative and interpretation of American history by the author of many distinguished historical works is sometimes controversial and always provocative. Johnson's views of individuals, events, themes, and issues are original, critical, and admiring, for he is, above all, a strong believer in the history and the destiny of the American people.
