First published in 1911 as the second edition of a 1900 original, this book provides a basic introduction to astronomy written by the former Astronomer Royal of Ireland. The text is illustrated with photographs, diagrams and drawings of astronomical phenomena, including certain comets and the constellations visible from the Northern and Southern Hemispheres. This book will be of value to anyone with an interest in the history of education and the teaching of astronomy.

Whether you are a theatre major looking forward to a career in the arts or a non-major interested in an overview to increase your appreciation as an audience member, THE ESSENTIAL THEATRE, 11th Edition, provides an engaging, insightful, and informative resource that will enrich your theatre experience throughout your life. Written by highly respected teachers and theatre historians, the text has earned its reputation as one of the most comprehensive, authoritative surveys of the theatre. Its vibrant treatment of theatre practice--past and present--catalogs the origins of theatre through postmodernism and performance art. The Eleventh Edition includes an all-new chapter devoted to musical theatre, new "Then and Now" boxes that link theatre history to present-day, and numerous new photos--including photos of actors you will quickly recognize from film and television.

This book discusses the principles and practical applications of data science, addressing key topics including data wrangling, statistics, machine learning, data visualization, natural language processing and time series analysis. Detailed investigations of techniques used in the implementation of recommendation engines and the proper selection of metrics for distance-based analysis are also covered.Utilizing numerous comprehensive code examples, figures, and tables to help clarify and illuminate essential data science topics, the authors provide an extensive treatment and analysis of real-world questions, focusing especially on the task of determining and assessing answers to these questions as expeditiously and precisely as possible. This book addresses the challenges related to uncovering the actionable insights in “big data,” leveraging database and data collection tools such as web scraping and text identification.This book is organized as 11 chapters, structuredas independent treatments of the following crucial data science topics:Data gathering and acquisition techniques including data creationManaging, transforming, and organizing data to ultimately package the information into an accessible format ready for analysisFundamentals of descriptive statistics intended to summarize and aggregate data into a few concise but meaningful measurementsInferential statistics that allow us to infer (or generalize) trends about the larger population based only on the sample portion collected and recordedMetrics that measure some quantity such as distance, similarity, or error and which are especially useful when comparing one or more data observationsRecommendation engines representing a set of algorithms designed to predict (or recommend) a particular product, service, or other item of interest a user or customer wishes to buy or utilize in some mannerMachine learning implementations and associated algorithms, comprising core data science technologies with many practical applications, especially predictive analyticsNatural Language Processing, which expedites the parsing and comprehension of written and spoken language in an effective and accurate mannerTime series analysis, techniques to examine and generate forecasts about the progress and evolution of data over timeData science provides the methodology and tools to accurately interpret an increasing volume of incoming information in order to discern patterns, evaluate trends, and make the right decisions. The results of data science analysis provide real world answers to real world questions. Professionals working on data science and business intelligence projects as well as advanced-level students and researchers focused on data science, computer science, business and mathematics programs will benefit from this book.
