 Whether they’re searching for the cosmic big picture or studying Earth’s most humble life forms, scientists must develop a thorough understanding of light. This program guides viewers through cutting-edge physics, biology, and forensics as it explores light’s fundamental characteristics and uses. Viewers are introduced to MacArthur Fellow and Harvard researcher Dr. Lene Hau, who outlines her method for slowing light down, despite Einstein’s assertion to the contrary. In addition, the program sheds light—literally—on new tools and techniques in crime scene investigations, while studying photosynthesis in plants and the surprising visual acuity of jellyfish.
