Why are candle flames yellow? Why does ultraviolet light supposedly kill vampires? What about the monocle? Why was the monocle-a corrective lens that only corrects vision in a single eye-so popular among businessmen and politicians for so many years? Stephen R. Wilk answers all this and so much more in Sandbows and Black Lights. This book is a collection of original essays on weird and unusual topics surrounding optics. Wilk uses the BBC's formula of "Education by Stealth" to explain unusual facets of science and technology through the matrix of interesting and cultural paths, all the while weaving in math equations in an accessible way. The first part of the book focuses on the history, the second moves to odd scientific approaches to visual phenomena, and the third part explains the unique use of optics in fiction, movies, and comic books over time. Chapters cover everything from endless corridors to the beam of light over treasure chests in movies. Whether he is explaining a rare discovery or answering a seemingly unapproachable question, Wilk is able to lure readers in on every page. He has a unique ability to turn complex science into an engaging story, and this book is full of narratives on esoteric topics anyone will find intriguing. Sandbows and Black Lights provides an enticing and entertaining look at physical illusions in a whole new way.

How the Ray Gun Got Its Zap is a collection of essays that discusses odd and unusual topics in optics. Though optics is a fairly specialized branch of physics, this book extracts from the discipline topics that are particularly interesting, mysterious, culturally relevant, or accessible. The essays all first appeared, in abbreviated form, in Optics and Photonics News and in The Spectrograph; the author has updated and expanded upon each of them for this book. The book is divided into three thematic sections: History, Weird Science, and Pop Culture. Chapters will discuss surprising uses of optics in classics and early astronomy; explain why we think of the sun as yellow when it is actually white; present how the laser is used in popular film; and profile the eccentric scientists who contributed to optics. The essays are short and entertaining, and can be read in any order. The book should appeal to general audiences interested in optics or physics more generally, as well as members of the scientific community who are curious about optics phenomena.

Medusa presents a new and different look at the myth of Perseus and Medusa and its interpretation. Starting with a look at the nature of myths and a recounting of the story, the book considers the myth and the explanations which have arisen to explain it. New interpretations are suggested which are rooted in astronomy, psychology, art and architecture. The role of the gorgon in the modern world is examined, showing that the myth of Medusa is very much alive.

Medusa, the Gorgon, who turns those who gaze upon her to stone, is one of the most popular and enduring figures of Greek mythology. Long after many other figures from Greek myth have been forgotten, she continues to live in popular culture. In this fascinating study of the legend of Medusa, Stephen R. Wilk begins by refamiliarizing readers with the story through ancient authors and classical artwork, then looks at the interpretations that have been given of the meaning of the myth through the years. A new and original interpretation of the myth is offered, based upon astronomical phenomena. The use of the gorgoneion, the Face of the Gorgon, on shields and on roofing tiles is examined in light of parallels from around the world, and a unique interpretation of the reality behind the gorgoneion is suggested. Finally, the history of the Gorgon since classical times is explored, culminating in the modern use of Medusa as a symbol of Female Rage and Female Creativity.
