The book is about the post-relativity philosophy of time as championed by Bertrand Russell and Einstein. It argues that The Past, Present and Future notion of time is an illusion. The sun, as daylight, is on constantly with no temporal past and future, except in chemistry perhaps. Only the earth's revolutions bring temporary days and nights. So the Bertrand Russell notion that under relativity man constructs his time is logically unassailable (the days, weeks, months and years are all human concepts.) Relativity allows time to begin from anywhere. So the revolutionary view is that there are or can be as many times as there are frames, or planets---a world-changing idea but true because it is based on objective, physical experiments, but generally ignored.
The book demonstrates the importance of history and philosophyof science for science education. It provides a case study of thependulum, showing the pivotal role played by the pendulum in theScientific Revolution. It describes how the pendulum enabled thecreation of accurate clocks that, among other things, enabled thelong-standing problem of longitude to be solved. The book charts howthe solution of the longitude problem was of enormous social, economicand cultural significance for European and consequently world history.Further, the book shows how the discovery of the laws of pendulummotion by Galileo, Huygens and Newton hinged on the acceptance of anew methodology for science. The pendulum laws are a window throughwhich to view the fascinating mixture of experiment, mathematics andphilosophy that characterized the foundations of modern science- the Galilean-Newtonian paradigm - anddistinguished it from Aristotelian, medieval and commonsense science.The book covers: learning about the nature ofscience; navigation andthe longitude problem; ancient and medieval timekeeping; Galileo'sanalysis of pendulum motion; Huygens, Hooke, Newton and the pendulum; clocks and culture; science and philosophy; the mechanical world view; teaching about time and pendulum motion; and teacher education andculture.The book defends a liberal, or contextual, approach to the teaching ofscience. It shows how understanding the scientific, philosophical andcultural contexts and ramifications of the pendulum laws can allowteachers to plan more engaging lessons, and conduct informativehistorical- investigative experiments. Students can re-live history.Contextual understanding of the pendulum allows connections to bemadewith other parts of the science curriculum, and with other subjectareas such as geography, literature, religion, music and mathematics.Readers will come away with a deeper understanding of the nature ofscience and its
From the author of Eichmann in Jerusalem and The Origins of Totalitarianism, “a book to think with through the political impasses and cultural confusions of our day” (Harper’s Magazine) Hannah Arendt’s insightful observations of the modern world, based on a profound knowledge of the past, constitute an impassioned contribution to political philosophy. In Between Past and Future Arendt describes the perplexing crises modern society faces as a result of the loss of meaning of the traditional key words of politics: justice, reason, responsibility, virtue, and glory. Through a series of eight exercises, she shows how we can redistill the vital essence of these concepts and use them to regain a frame of reference for the future. To participate in these exercises is to associate, in action, with one of the most original and fruitful minds of the twentieth century.

“A revolution is happening in speculative fiction, and Annalee Newitz is leading the vanguard."--Wil Wheaton From Annalee Newitz, founding editor of io9, comes a story of time travel, murder, and the lengths we'll go to protect the ones we love. 1992: After a confrontation at a riot grrl concert, seventeen-year-old Beth finds herself in a car with her friend's abusive boyfriend dead in the backseat, agreeing to help her friends hide the body. This murder sets Beth and her friends on a path of escalating violence and vengeance as they realize many other young women in the world need protecting too. 2022: Determined to use time travel to create a safer future, Tess has dedicated her life to visiting key moments in history and fighting for change. But rewriting the timeline isn’t as simple as editing one person or event. And just when Tess believes she's found a way to make an edit that actually sticks, she encounters a group of dangerous travelers bent on stopping her at any cost. Tess and Beth’s lives intertwine as war breaks out across the timeline--a war that threatens to destroy time travel and leave only a small group of elites with the power to shape the past, present, and future. Against the vast and intricate forces of history and humanity, is it possible for a single person’s actions to echo throughout the timeline? Praise for The Future of Another Timeline: "An intelligent, gut-wrenching glimpse of how tiny actions, both courageous and venal, can have large consequences. Smart and profound on every level.”—Publishers Weekly (starred review) "You close the book reeling with questions about your own life and your part in changing the future."—Amy Acker, actress (Angel and Person of Interest) At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.
