This astronomical atlas features not only conventional star and galaxy maps, but also spectacular three-dimensional stereographs (glasses provided). The book contains three sets of comprehensive full-sky maps that cover local space, regional space, and distant space -- with over 20,000 galaxies. All the stereographs have been derived from the most accurate data available, including results from the Hipparcos satellite, and can be used to measure the approximate distances between the objects depicted. The distant space maps represent one of the most complete mappings of the galaxies available to amateur astronomers, and their accompanying three-dimensional views provide tantalising glimpses of structure at the largest scale of the universe.

The year 1973 marked the highest peak of IAU activity up to now. Besides the Gen eral Assembly in Sydney, and the Extraordinary General Assembly in Poland, there were held eleven IAU Symposia and one Colloquium. Several IAU Publications cover this activity. The Proceedings of the Symposia are published in separate Volumes, while the Transactions of the General Assembly and of the Extraordinary General Assembly contain short reports of the Commission meetings, the administrative sessions, and the opening ceremonies. The present Volume covers some of the scientific Highlights of the General As sembly and of the Extraordinary General Assembly. It contains five Invited Dis courses given in Sydney and Poland, some selected papers, and the Joint Discussions at the General Assembly of Sydney. Of course, there were many more papers of special interest presented in Sydney that could not be included in this Volume. Their titles can be seen in the reports of the various Commissions. It is regrettable that the Invited Discourses of C. H. Townes (Interstellar Molecules) and F. J. Low (Infrared Astronomy) were not submitted for publication. Also only five papers or abstracts of the Joint Discussion on the 'Origins of the Moon and Satellites' have been available. Despite these minor shortcomings, I believe that the present Volume is faithful to its title: it gives a substantial part of the Highlights of Astronomy in 1973.

A quantitative yet accessible undergraduate introduction to the collection and analysis of observational data in optical and infrared astronomy.

#1 NEW YORK TIMES BESTSELLER • For fans of The Hunger Games, Divergent, and Red Rising comes a gripping sci-fi adventure in which a group of teenagers wake up in a mysterious corridor with no knowledge of who they are or how they got trapped. Their only hope lies with an indomitable young woman who must lead them not only to answers but to survival. “I open my eyes to darkness. Total darkness. I hear my own breathing, but nothing else. I lift my head . . . it thumps against something solid and unmoving. There is a board right in front of my face. No, not a board . . . a lid.” A teenage girl awakens to find herself trapped in a coffin. She has no idea who she is, where she is, or how she got there. Fighting her way free brings little relief—she discovers only a room lined with caskets and a handful of equally mystified survivors. Beyond their room lies a corridor filled with bones and dust, but no people . . . and no answers. She knows only one thing about herself—her name, M. Savage, which was engraved on the foot of her coffin—yet she finds herself in charge. She is not the biggest among them, or the boldest, but for some reason the others trust her. Now, if they’re to have any chance, she must get them to trust one another. Whatever the truth is, she is determined to find it and confront it. If she has to lead, she will make sure they survive. Maybe there’s a way out, a rational explanation, and a fighting chance against the dangers to come. Or maybe a reality they cannot comprehend lies just beyond the next turn. Praise for Alive “Suspenseful . . . [Alive] lives up to its hype, packing plenty of thrills.”—Entertainment Weekly “Fascinating and intriguing . . . a cross between Lord of the Flies and The Maze Runner and yet . . . so much more.”—Fresh Fiction “A ripping, claustrophobic thunderbolt of a novel, Scott Sigler’s Alive gives us an unforgettable young hero who must find the inner strength to lead without knowing where she is, who she is, and how bitterly the odds are stacked against her.”—Pierce Brown, New York Times bestselling author of Red Rising “Sigler has created a wonderful and engrossing character in M. Savage. Strong and smart, but with the naïveté and misgivings of any teenage girl, she’s someone you’ll definitely want on your side when s*** hits the fan, which it most certainly does.”—Veronica Belmont, host of Sword & Laser “A tense, unsettling page-turner of a story—both deeply strange and wildly compelling.”—Cherie Priest, author of Boneshaker and Maplecroft “From the first page I was hooked. The puzzle unfolds masterfully, right down to the last page.”—Dr. Phil Plait, author of Bad Astronomy

Since the mid-1820s, a series of lectures has been delivered each year over the Christmas period in the world-famous Faraday Lecture Theatre at The Royal Institution of Great Britain by prominent scientists, addressed specifically to an audience of children. Initially made accessible in book form, the lectures have been nationally televised throughout the UK and distributed worldwide since the 1960s, making them accessible to an even larger audience. The importance of these lectures in promoting science to a broad audience is perhaps best gauged by the fact that an image of one of Faraday's lectures appeared on the Bank of England £20 note in the 1990s.This anthology brings together, for the first time, a carefully chosen selection of 11 lectures from the 1860s to the 1990s. The selection includes lectures by Michael Faraday, arguably the most important and influential 19th-century physicist, and Lawrence Bragg, the youngest ever winner of the Nobel Prize. Through this work, readers will come to grips with the changing nature of popular science lectures over the past 140 years.
