In honor of Star Wars Day, this episode explores futuristic light technologies seen in science fiction—like invisibility cloaks or powerful directed energy— and how far away we are from such innovations. In this episode, Matt Jones, a chemist at Rice University and Northwestern alum, explains how scientists are learning to control light by engineering materials at the nanoscale and why when materials are reduced to billionths of a meter, they begin to exhibit entirely new optical properties—from color-changing nanoparticles to structures that interact with light in unexpected ways. The conversation explores the emerging field of metamaterials and how curiosity-driven, fundamental science lays the groundwork for innovations that may shape the future.
