More than a simple chronology, this volume explores the technical resources used to measure time—solar, hydraulic, mechanical, or electrical—just as it explains the key factors behind the major breakthroughs in the science of horology. From ancient astronomical observatories to atomic clocks, instruments for telling time have always been closely linked to the cutting-edge sciences of the day, ranging from medicine and navigation to aeronautics. Inventions in timekeeping have been crucial to the organization of human society and to activities such as farming, industry, and trade. Each new development was based on the needs and accomplishments of its day yet spurred further discoveries. Writing a history of time means viewing human genius through the prism of the steady mastery of a crucial technology. The patient, long-term conquest of accuracy has been the result of successive advances from sundial to wristwatch up to the recent exploits of the heirs to this age-old quest, namely master horologists of the twenty-first century.

How to base learning on mastery instead of time What if you could remove time and space pressures from the process of teaching and learning? The authors of Off the Clock not only suggest this, but they have implemented it in New Hampshire. Due in part to their work, the New England Consortium won the 2011 Frank Newman Award for State Innovation through the Education Commission of the States. This book′s core idea is that student achievement should be based on mastering competencies instead of "seat time." In addition, learning does not need to be restricted to a school building or traditional school calendar. Fred Bramante and Rose Colby describe a uniquely 21st century learning environment in which: Every student is engaged Parents and students have more control over learning Dropouts are all but eliminated Curriculum becomes virtually limitless, project-based, and interdisciplinary This text for educators, policymakers, parents, and community members provides a comprehensive approach to implementing a large-scale competency-based reform initiative. Wherever this model is applied, public education will be vastly improved, more efficient, and, quite possibly, less expensive. The ultimate beneficiaries will be our nation′s children.

Mastered by the Clock is the first work to explore the evolution of clock-based time consciousness in the American South. Challenging traditional assumptions about the plantation economy's reliance on a premodern, nature-based conception of time, Mark M. Smith shows how and why southerners--particularly masters and their slaves--came to view the clock as a legitimate arbiter of time. Drawing on an extraordinary range of eighteenth- and nineteenth-century archival sources, Smith demonstrates that white southern slaveholders began to incorporate this new sense of time in the 1830s. Influenced by colonial merchants' fascination with time thrift, by a long-held familiarity with urban, public time, by the transport and market revolution in the South, and by their own qualified embrace of modernity, slaveowners began to purchase timepieces in growing numbers, adopting a clock-based conception of time and attempting in turn to instill a similar consciousness in their slaves. But, forbidden to own watches themselves, slaves did not internalize this idea to the same degree as their masters, and slaveholders found themselves dependent as much on the whip as on the clock when enforcing slaves' obedience to time. Ironically, Smith shows, freedom largely consolidated the dependence of masters as well as freedpeople on the clock.
