Episode notes

A lot of my early PhD work was more related to what people would call an interference effect or scattering cancellation. The idea here is this goes back to light being a wave and waves can combine to create constructive interference and destructive interference. If you're familiar with Young's double slit experiment, I am not yet. That's sort of the classic demonstration of interference. You shine light through two small holes. You get light waves coming out of the two holes. And if you set it up correctly, if you shine the light from those two holes on a screen, you see these bright and dark bands.

Invisibility cloaks. Transparent frogs. Stealth bombers. Gorilla mischief. Theoretical optical physicist and Invisible Photologist Dr. Greg Gbur joins Alie to chat about light, illusions, secret technology, science fiction inspiration, terrible camouflage, great movies, historical mishaps, and even a few great household life hacks – and why you should go read a book on your porch. Perhaps his book, Invisibility: The History and Science of How Not To Be Seen.
