Optics—a field of physics focusing on the study of light—is also central to many areas of biology, including vision, ecology, botany, animal behavior, neurobiology, and molecular biology. The Optics of Life introduces the fundamentals of optics to biologists and nonphysicists, giving them the tools they need to successfully incorporate optical measurements and principles into their research. Sönke Johnsen starts with the basics, describing the properties of light and the units and geometry of measurement. He then explores how light is created and propagates and how it interacts with matter, covering topics such as absorption, scattering, fluorescence, and polarization. Johnsen also provides a tutorial on how to measure light as well as an informative discussion of quantum mechanics. The Optics of Life features a host of examples drawn from nature and everyday life, and several appendixes that offer further practical guidance for researchers. This concise book uses a minimum of equations and jargon, explaining the basic physics of light in a succinct and lively manner. It is the essential primer for working biologists and for anyone seeking an accessible introduction to optics.

Wall Street Journal and USA Bestseller How to Connect with What’s Most Important in a Hyperconnected World Social media has the power to do a lot of good, but it can also get in the way of authenticity and create a sense of disillusionment. In Overliked, pastor and author Rob Singleton asks readers to take a closer look at the optics in their lives and in the world around them. This is a book about understanding how to see “likes” and “selfie” culture for what they really are and how to connect with the heart of God to build out a new way of thinking about social image. We have technology and social tools all at our disposal, but when we recognize that so many in our culture now look for acceptance in how they’re perceived, feel pressure to project something about themselves that isn’t true, or take action based on facts that have been spun, that’s a problem that runs deep. Singleton shows readers how to find their way through the complexities by pointing them to God, who created truth, genuine love, and meaningful relationships. Written for those who believe—for this generation and the next—that they need to get a better handle on what’s real in this culture and in the lives of those they care about, this book brings authenticity and hope to the center of it all. Singleton offers powerful insights into how we can better leverage the information in the world around us without losing who we are. When we begin to see the real us behind the avatars, we gain the clarity we need to live better, love bigger, and become who we were always meant to be.

An ambitious venture into Nietzsche’s envisioned philosophy for the future. Nietzsche advocated for a post-theistic “philosophy of the future”—a new approach to human reality that would bend Western thought away from nihilism in a life-affirming, value-creative direction. His early demise left this endeavor only just begun. In Nietzsche Pursued, Richard Schacht examines Nietzsche’s revisionist approach to familiar philosophical topics, exploring how some may be further pursued in Nietzschean ways. Each chapter focuses on one topic that is central to Nietzsche's vision of what philosophy can and should be and do. Among them: his kind of naturalism, humanity, perspectivism, morality, and music. Building on his analysis in Nietzsche’s Kind of Philosophy, Schacht invites readers to see with new appreciation the ongoing significance of Nietzsche’s thought for philosophy’s future.
