Observing Variable Stars


Book Description

Observing variable stars is one of the major contributions amateur astronomers make to science. There are 36,000 variable stars listed in the General Catalogue of Variable Stars, so it is clearly impossible for the limited number of professional observatories to target even the majority of them. That's where amateur astronomers come in - thousands of them turning their telescopes to the sky every night. Variable star observing is the most popular of "real science" activities for amateurs, and Gerry Good's book provides everything needed. The first part of the book provides a highly detailed account of the various classes of variable star, with examples, illustrations and physical descriptions. The second section covers practical aspects of observing, everything from preparation and planning, through observing techniques, to data management and reduction.




STEM Gems


Book Description

Tired of seeing the same careers foisted upon women in TV, movies and magazines? Chemical engineer Stephanie Espy, a graduate of MIT, UC Berkeley and Emory University, tells the stories of 44 inspiring women in STEM to show girls and young women around the world a new set of women heroes to look up to.The statistics for women in Science, Technology, Engineering and Mathematics (STEM) careers are just plain sad. In recent years, fewer than 20% of college graduates in engineering and computer science were women. While stereotypes pervade about women in these fields, the truth is that most girls have never even heard of these careers and are not aware of the wide range of options that exist.In STEM Gems, you and your daughter, niece, neighbor, friend or student will discover: The stories of 44 inspiring women in diverse STEM fields and how they made it; The challenges these incredible women faced in pursuit of their dreams; The tremendous accomplishments these Gems have achieved in their respective STEM fields; Advice on how to pursue science, technology, engineering and mathematics careers; Actionable steps girls and young women can take right now to set themselves up for success; What girls and young women can expect in a promising STEM career, and much, much more!Through the powerful stories of the STEM Gems in this book, girls and young women will have their pick of current role models of various ages, ethnicities and job types. And through the eight chapters that outline actionable steps, girls and young women will learn what they can do right now, today, to set themselves up for success and to create their own unique paths. STEM Gems is relatable, encouraging and inspiring, demonstrating the limitless possibilities for the next generation of women.




Herbarium


Book Description

A treasury like no other Since the 1500s, scientists have documented the plants and fungi that grew around them, organizing the specimens into collections. Known as herbaria, these archives helped give rise to botany as its own scientific endeavor. Herbarium is a fascinating enquiry into this unique field of plant biology, exploring how herbaria emerged and have changed over time, who promoted and contributed to them, and why they remain such an important source of data for their new role: understanding how the world’s flora is changing. Barbara Thiers, director of the William and Lynda Steere Herbarium at the New York Botanical Garden, also explains how recent innovations that allow us to see things at both the molecular level and on a global scale can be applied to herbaria specimens, helping us address some of the most critical problems facing the world today. At its heart, Herbarium is a compelling reminder of one of humanity’s better impulses: to save things—not just for ourselves, but for generations to come.

Profiles of Rafinesque


Book Description

Was the nineteenth-century naturalist C. S. Rafinesque insane? Did he die in "abject poverty?" Just what is the value of his contributions to scientific nomenclature? Charles Boewe's Profiles of Rafinesque takes up these questions and others. Among early naturalist, C. S. Rafinesque is second only to John James Audubon in the volume of commentary that has been written about him and his works. In contrast to Audubon, however, he has yet to receive an adequate biography. In this volume, Charles Boewe collects the essays of thirteen writers to provide the most comprehensive portrait now available of a persistently controversial character as well as a glimpse into the world of scientific discovery on the early American frontier. Rafinesque (1783-1840) is best known for his contributions to scientific classification and nomenclature; he gave Latin names to some 6,700 plants in what his critics described as a "complete monomania" for establishing new genera and species. This passion for discovery may not have kept him from following to logical conclusion his own insights such as that of biological variation, which Darwin so famously explicated just a few years later. Rafinesque's broad interests included the languages of Native Americans and their archaeological remains; these studies contributed to philology and ethnography. He founded a savings bank and marketed a tuberculosis remedy, partially financing his publishing endeavors with his profits. He wrote on subjects ranging from astronomy to zoology, both for professional and for general audiences. Here are twenty essays, forty-six illustrations, and a summation of 160 years of Rafinesque scholarship, which together reveal a multifaceted individual. Boewe dispels certain myths about Rafinesque's mental state, the circumstances of his birth and death, and the validity of his scientific work--on these topics Boewe and the other contributors provide a well-rounded picture of an intriguing nineteenth-century American naturalist.
