Book Description
In this fascinating book Masatoshi Kajita recounts the importance of precise measurements and their inherent uncertainty, before telling the story of humankind's efforts to define and measure time with increasing accuracy, culminating in the development of atomic clocks. These improvements in the accurate measurement of time and frequency have played a pivotal role in the development of modern science; including the confirmation of Einstein's Theory of Relativity, and the recent detection of gravity waves. Furthermore, such measurements afforded by atomic clocks and other mechanisms are being used to examine key questions about the very fundamentals of our universe, the possibility of symmetry violation and even testing the idea that there may be variation of the fundamental constants themselves over time.

Book Description
Anthony F. Aveni gathers specialists from diverse fields to discuss temporal concepts gleaned from the people of Mesoamerica and the Andes. Essays address how they reckon and register time and how they sense time and its moral dimensions. To them, time is a feature of the process of perception, not just the sharp present ingrained in Western minds.

Book Description
Measure, Use, Improve! Data Use in Out-of-School Time shares the experience and wisdom from a broad cross-section of out-of-school time professionals, ranging from internal evaluators, to funders, to researchers, to policy advocates. Key themes of the volume include building support for learning and evaluation within out-of-school time programs, creating and sustaining continuous quality improvement efforts, authentically engaging young people and caregivers in evaluation, and securing funder support for learning and evaluation. This volume will be particularly useful to leadership-level staff in out-of-school time organizations that are thinking about deepening their own learning and evaluation systems, yet aren’t sure where to start. Authors share conceptual frameworks that have helped inform their thinking, walk through practical examples of how they use data in out-of-school time, and offer advice to colleagues.
