- Chemistry 2e is designed to meet the scope and sequence requirements of the two-semester general chemistry course. The textbook provides an important opportunity for students to learn the core concepts of chemistry and understand how those concepts apply to their lives and the world around them. The book also includes a number of innovative features, including interactive exercises and real-world applications, designed to enhance student learning. The second edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Substantial improvements have been made in the figures, illustrations, and example exercises that support the text narrative. Changes made in Chemistry 2e are described in the preface to help instructors transition to the second edition. The first edition of Chemistry by OpenStax is available in web view here.
- Star Tales - Volans (ianridpath.com)
One of the 12 new constellations introduced at the end of the 16th century by the Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman. Volans represents a real type of fish found in tropical waters that can leap out of the water and glide through the air on wings. Sometimes the fish landed on the decks of ships and were used for food. In the sky the flying fish is imagined being chased by the predatory Dorado, as happens in reality.
