Light phenomena have intrigued humankind since prehistory. Think of the rainbow, a sunset on the sea, a game of shadows. Humans have always used light for their own needs, from cooking food to illuminating a room. However, light is not only limited to what we can see with our eyes. The invisible part of the electromagnetic spectrum is broad and dynamic. This book outlines the mysteries and wonders of electromagnetism, heat, and light. It also covers the history of our scientific understanding of light. The dark as well as the bright sides of light are fully explored in these pages, from their impact on our world to their use in cutting-edge technologies in a variety of fields. Numerous full-color images and drawings complement the text, and light phenomena are explained in a simple and engaging way.

'Brought to Light' invites readers to step back to a time when photography, X-rays, and movies were new, when forays into the world beneath the skin or the realm beyond our everyday vision captivated scientists and the public alike. The text ultimately traces the rise of popular science.

The 5 class sessions, of 45-60 minutes each, deepen student understanding of the electromagnetic spectrum, enabling students to detect and consider wavelengths other than visible light. Activities feature energy stations, including infrared (TV remote); microwave (pager); ultraviolet (black light) and other devices. Students come up with their own tests to see what blocks each wavelength, and what does not. They learn how these other wavelengths can be used to "see" things we cannot see with our eyes.

Throughout history, Western esoteric movements have provided meaning and power for what the Rosicrucians of the early modern period called the quest for “Universal Reformation”—the utopian restructuring of religion, science, the arts, and human society. Yet Western esotericism has been roundly ignored as a source of reflection in mainstream Christian theology, including the radical theologies of liberation that might otherwise see in esotericism a kindred spirit to their commitment to radical social change. In The Inner Church is the Hope of the World, guided by his work in contemporary movements for social change, Nicholas Laccetti puts Western esotericism in dialogue with liberation theology, treating esotericism as a legitimate source of spiritual and theological insight. If, as Gustavo Gutiérrez writes, “God is revealed in history,” then we will also encounter God within the particular history of human religious expression that is Western esotericism. And from these theological reflections, the Inner Church of the esotericists, occultists, and mystics is revealed to be the true ekklesia of all who have conformed themselves to God’s vision of freedom and liberation, and who struggle to enact that vision in human society. The Inner Church is truly the hope of the world.
