This course begins with a historical survey of humankind’s understanding of light and continues with chapters covering: the nature of light, color, making light, vision, atmospheric phenomena, and light in the cosmos. The course offers to the nonspecialist a view of the properties and behaviors of light as well as an understanding of human efforts to unlock the secrets of light. Learn how humankind has discovered and exploited the elusive properties of light to inform and improve our world—from rainbows to black holes, from illumination to the nature of color science, from ecological advances to the miracle of vision. Appreciate the marvels that the study of light reveals in technological advances (e.g., color printers and flat-panel TVs) and the hues of our universe (e.g., solar halos and butterfly wings). | Lecture + Q&A.
