Girolamo Cardano (1501-1576), renowned as a mathematician, encyclopedist, astrologer, and autobiographer, was by profession a medical practitioner. His copious writings on medicine reflect both the complexity and diversity of the Renaissance medical world and the breadth of his own interests. In this book, Nancy Siraisi draws on selected themes in Cardano's medical writings to explore in detail the relation between medicine and wider areas of Renaissance culture. Cardano’s medical advice included the suggestion that "the studious man should always have at hand a clock and a mirror"—a clock to keep track of the passage of time and a mirror to observe the changing condition of his body. The remark, which recalls his astrological and autobiographical interests, is emblematic of the many connections between his medicine and his other pursuits. Cardano’s philosophical eclecticism, beliefs about occult forces in nature, theories about dreams, and free transitions between academic and popularizing scientific writing also contributed to his medicine. As a physician, he greeted two different types of medical innovation in his lifetime with equal enthusiasm: improved access to the Hippocratic corpus and Vesalian anatomy. Cardano presented himself as a practitioner with special gifts. Yet his medical learning remained rooted in the Galenic tradition that he often criticized. Meanwhile, he negotiated a career in a medical community characterized by personal and social rivalries, a competitive medical marketplace, and strong institutional and religious pressures.

It was a warm summer day in 1951 when Rose Pottinger and Mrs. Zimmermann entered the tunnel. When they had emerged, it was snowing...and the year was 1828. Mrs. Zimmermann had felt that the ghost of Granny Wetherbee, who had taught Mrs. Zimmermann witchery, was in trouble and needed help. So she and Rose Rita had traveled to Pennsylvania where Granny had lived. They never dreamed that they would also journey back to a time long ago where they would encounter a sorcerer more terrifying than either could have imagined.

Of Clocks and Time takes readers on a five-stop journey through the physics and technology (and occasional bits of applications and history) of timekeeping. On the way, conceptual vistas and qualitative images abound, but since mathematics is spoken everywhere the book visits equations, quantitative relations, and rigorous definitions are offered as well. The expedition begins with a discussion of the rhythms produced by the daily and annual motion of sun, moon, planets, and stars. Centuries worth of observation and thinking culminate in Newton's penetrating theoretical insights since his notion of space and time are still influential today. During the following two legs of the trip, tools are being examined that allow us to measure hours and minutes and then, with ever growing precision, the tiniest fractions of a second. When the pace of travel approaches the ultimate speed limit, the speed of light, time and space exhibit strange and counter-intuitive traits. On this fourth stage of the journey, Einstein is the local tour guide whose special and general theories of relativity explain the behavior of clocks under these circumstances. Finally, the last part of the voyage reverses direction, moving ever deeper into the past to explore how we can tell the age of "things" - including that of the universe itself.

A highly imaginative fantasy book for children and young adults. Written in the authors’ unmistakable style, the book transports readers to a different world. The narrative surrounds the theme of time and follows people who live inside a clock.

Rikker felt his gut tightening up. After thirty years as an intelligence officer, he always thought six steps ahead of everyone else. He always knew what to expect, and most of the time he was right. He didn't like surprises and avoided them by being better than the other guy. But this was different, he'd been caught off guard, and, he had no idea of what to expect. In the back of his head he could hear Mary's voice saying, 'what if, Charles, what if?' Colonel Charles Rikker is too logical to believe that anything mysterious or dark has entered his life. He's risked his life for countless covert operations, and he has always known the risks involved. But this journey is only a project, a simple trip to find an antique grandfather clock. His mind is as fit as his body, but nothing could prepare Charles for the Emit Levart Clock Shop. The entire world has heard and seen reports of the unexplained deaths of some of the world's most prominent scientists and engineers, and also of America's favorite billionaire. But Charles learns the horrifying truth-only because it came to him in the clock shop. He doesn't know why he has been chosen, but he does know that if he tries to explain the peculiar circumstances, no one will believe him anyway.
