Episode notes

Lenticular ridges are like corrugated sheets of a bunch of clear cylinders fused together, making something that's ribbed and can throw off light. It can blur everything in the horizontal direction, but in the vertical direction, everything will look exactly the same. Do you have thoughts on Vantablack, the darkest pigment, like the least reflective paint in the world?

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.
