Time's Telescope For 1821


Book Description

Times Telescope for 1821 is an almanac-like publication offering a yearly review of important events in science, technology, and nature. First published in 1820 by the editors of The Times newspaper, the book includes articles on astronomy, physics, and natural history, along with a variety of tables and charts providing useful information for the general public. Despite its somewhat dry subject matter, the Times Telescope provides a fascinating glimpse into the world of early 19th-century science and popular culture.

The Optimist's Telescope


Book Description

Named a Best Book of 2019 by NPR “How might we mitigate losses caused by shortsightedness? Bina Venkataraman, a former climate adviser to the Obama administration, brings a storyteller’s eye to this question. . . . She is also deeply informed about the relevant science.” —The New York Times Book Review A trailblazing exploration of how we can plan better for the future: our own, our families’, and our society’s. Instant gratification is the norm today—in our lives, our culture, our economy, and our politics. Many of us have forgotten (if we ever learned) how to make smart decisions for the long run. Whether it comes to our finances, our health, our communities, or our planet, it’s easy to avoid thinking ahead. The consequences of this immediacy are stark: Deadly outbreaks spread because leaders failed to act on early warning signs. Companies that fail to invest stagnate and fall behind. Hurricanes and wildfires turn deadly for communities that could have taken more precaution. Today more than ever, all of us need to know how we can make better long-term decisions in our lives, businesses, and society. Bina Venkataraman sees the way forward. A journalist and former adviser in the Obama White House, she helped communities and businesses prepare for climate change, and she learned firsthand why people don’t think ahead—and what can be done to change that. In The Optimist’s Telescope, she draws from stories she has reported around the world and new research in biology, psychology, and economics to explain how we can make decisions that benefit us over time. With examples from ancient Pompeii to modern-day Fukushima, she dispels the myth that human nature is impossibly reckless and highlights the surprising practices each of us can adopt in our own lives—and the ones we must fight for as a society. The result is a book brimming with the ideas and insights all of us need in order to forge a better future.

Ian Stargazer


Book Description

The telescope is literally the world's most far-reaching invention. It can unlock nature's secrets in the remotest corners of the universe. It is a time machine, allowing us to look billions of years into the past for answers to some of our most profound questions. In its 400-year history, the telescope has progressed from a crudely fashioned tube holding a couple of spectacle lenses to colossal structures housed in space-age cathedrals. The history of the telescope is a rich story of ingenuity and perseverance involving some of the most colourful figures of the scientific world. It begins in ancient times, gathers momentum through the Renaissance, with the first recorded telescope bursting onto the scene in the middle of a diplomatic crisis in seventeenth century Holland, and takes us to the limits of space with the cutting-edge telescopes of today. Written by Fred Watson, one of Australia's best-loved astronomers, Stargazer brings the story of the telescope to a general readership for the first time.

The Science of Time 2016


Book Description

The uses of time in astronomy - from pointing telescopes, coordinating and processing observations, predicting ephemerides, cultures, religious practices, history, businesses, determining Earth orientation, analyzing time-series data and in many other ways - represent a broad sample of how time is used throughout human society and in space. Time and its reciprocal, frequency, is the most accurately measurable quantity and often an important path to the frontiers of science. But the future of timekeeping is changing with the development of optical frequency standards and the resulting challenges of distributing time at ever higher precision, with the possibility of timescales based on pulsars, and with the inclusion of higher-order relativistic effects. The definition of the second will likely be changed before the end of this decade, and its realization will increase in accuracy; the definition of the day is no longer obvious. The variability of the Earth's rotation presents challenges of understanding and prediction. In this symposium speakers took a closer look at time in astronomy, other sciences, cultures, and business as a defining element of modern civilization. The symposium aimed to set the stage for future timekeeping standards, infrastructure, and engineering best practices for astronomers and the broader society. At the same time the program was cognizant of the rich history from Harrison's chronometer to today's atomic clocks and pulsar observations. The theoreticians and engineers of time were brought together with the educators and historians of science, enriching the understanding of time among both experts and the public.
