This book explores the captivating colors that appear in the atmosphere of the earth: coronas, glories, halos, rainbows, dawn and dusk. Using the holistic observational method developed by Goethe in his Theory of Color, this book offers the reader a new way of relating to atmospheric colours. In its attempt to bridge the wide span between the physics of atmospheric colours and a spiritual approach to them, the path of unfolding descriptions and thoughts becomes artistic in itself. Extraordinary photographs and references to modern literature and websites round out the work. The book should prove helpful to scientists looking for a different approach to optics or an introduction to Goethe's phemelogical science, to teachers seeking a new approach to optics lessons, and to anyone who loves these colours and wishes to deepen their relationship to them.
Johannes Kuhl, physicist and leader of the Science Section at the Goetheanum, was born in 1953 in Hamburg, Germany. He studied physics in Hamburg and Gottingen, finishing with research in fluid dynamics at the Max Plank Institute. After a year of research at the Science Section at the Goetheanum, he taught physics, chemistry and mathematics at the original Waldorf School in Stuttgart Uhlandshohe. Since 1996, he has been the leader of the Science Section at the Goetheanum and a member of the collegium for the School of Spiritual Science. Since high school, core areas of interest for him have been modern physics and optics, as well as Goethean Science. He has given numerous lectures and seminars on these themes.
