A model of unsurpassed, comprehensive scholarship, this volume covers many fields, including professional and amateur astronomy. 196 black-and-white illustrations.

Complete, detailed instructions and numerous diagrams for constructing a do-it-yourself telescope. No complicated mathematics are involved, and no prior knowledge of optics or astronomy is needed to follow the text's step-by-step directions. Contents cover, among other topics, materials and equipment; tube parts and alignment; eyepieces, and related problems; setting circles; and optical principles. 1973 ed. Appendixes. Index. 6 plates. 100 figures.

From the author of the bestselling book 50 Things to See with a Small Telescope, this colorful edition explores the constellations with young readers, guiding them to dozens of galaxies, nebulae, and star clusters. Every page features a helpful "telescope view", showing exactly how objects appear through a small telescope or binoculars.

Between 1608 and 1610 the canopy of the night sky was ripped open by an object created almost by accident: a cylinder with lenses at both ends. Galileo’s Telescope tells how this ingenious device evolved into a precision instrument that would transcend the limits of human vision and transform humanity’s view of its place in the cosmos.

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.
