Master of Change: How to Excel When Everything Is Changing – Including You

by Brad Stulberg

A revelatory book on rethinking change and creating a rugged and flexible mindset amidst life's intensifying flux, from expert on sustainable excellence, coach, and bestselling author of The Practice of Groundedness.From social disruptions like economic recessions, pandemics, and new technologies to individual disruptions like getting married, career transitions, and becoming a parent, we undergo change and transformation—both good and bad—regularly. Change is not the exception, it’s the rule. Yet we endlessly fight it, often viewing it as a threat to our stability and sense of self.Master of Change flips this script on its head and offers a path for embracing and even growing from life’s constant instability.Brad Stulberg, sustainable excellence expert, coach, and bestselling author of The Practice of Groundedness, offers a new model that describes change as an ongoing cycle of order, disorder, and reorder—yes, we return to stability, but that stability is somewhere new. Drawing on modern science, ancient wisdom, and daily practice, Stulberg offers concrete principles for developing a mindset called rugged flexibility, along with habits and practices to implement it. Along the way, Stulberg reveals:How to be in conversation with change instead of it happening to you.The importance of expectationsWhy cultivating a rugged yet flexible sense of self is key to a strong identity.How to take productive action during a challenge.The paradox of both making meaning and moving forward.In the end, Stulberg reshapes our entire perception of change and shows us how to grow in its midst—ultimately helping us move forward better, stronger, and wiser than we were before.

Master of Galactic Astronomy: A Biography of Jan Hendrik Oort (Springer Biographies)

by Pieter C. van der Kruit

This accessible and entertaining biography chronicles the life and triumphs of astronomer Jan Hendrik Oort, who helped lay the foundations of modern astronomy in the 20th century. The book puts into context some of Oort's most significant achievements, including his discovery that the Milky Way rotates, as well as his famous hypothesis that our Solar System is surrounded by a reservoir of comets — now simply known as the Oort Cloud. Written by Oort’s former student, this fascinating story also delves into Oort’s pivotal role in the foundation of major astronomical facilities, including radio telescopes in the Netherlands and the European Southern Observatory (ESO), which now operates the most successful astronomical observatories in the world. The book draws extensively on new archival research through the Oort Archives, along with personal reminiscences by Oort’s son and astronomer-grandson, to paint a more detailed picture of Oort’s life not just as an astronomer, but also as a husband, father, and citizen. The strong public interest in comets triggered by the Rosetta mission to comet 67P/Churyumov–Gerasimenko and the recently discovered interstellar comet in the Solar System make this book particularly timely.

Mastering Modern Psychological Testing: Theory and Methods

by Cecil R. Reynolds Daniel N. Allen Robert A. Altmann

This book provides a comprehensive introduction to psychological assessment and covers areas not typically addressed in existing test and measurements texts, such as neuropsychological assessment and the use of tests in forensics settings. The book introduces the vocabulary of the profession and the most basic mathematics of testing early as being fundamental to understanding the field. Numerous examples are drawn from tests that the authors have written or otherwise helped to develop, reflecting the authors’ deep understanding of these tests and their familiarity with problems encountered in test development, use, and interpretation. Following the introduction of the basic areas of psychometrics, the book moves to areas of testing that represent various approaches to measuring different psychological constructs (memory, language, executive function, etc.), with emphasis on the complex issue of cultural bias in testing. Examples of existing tests are given throughout the book; however, this book is not designed to prepare students to go out and administer, score, and interpret specific psychological tests. Rather, the purpose of this book is to provide the foundational core of knowledge about tests, measurement, and assessment constructs, issues, and quantitative tools.Explains what constitutes a psychological test, how tests are developed, how they are best used, and how to evaluate their strengths and weaknesses;Describes areas of testing that represent different approaches to measuring different psychological constructs;Explains applications of psychological testing to issues in the courts;Addresses how test authors and publishers design and research tests to address the difficult and demanding issues of cultural differences in test performance and interpretation of test results.
