Did you know that #invisibility cloaks are #real?

From the 2nd c's Cap of Hades to #Marvel 's Invisible Woman, magic that renders one #invisible is a common theme in #mythology & #scifi.

In 2006, #theoretical #physicist John Pendry figured out that light could be bent around an object so that it renders it invisible.
This led to many advancements in metamaterial science, known as 'metamaterial cloaking'.

I've enjoyed this talk by Pendry: youtube.com/watch?v=VO6IrynhjK [start: 4:43min]

Interesting interview with the author of a book on the science of invisibility.

"Gbur is the author of a new book from Yale University Press, Invisibility: The History and Science of How Not to Be Seen, covering the earliest discoveries in optical physics through to the present, along with how invisibility has been portrayed in science fiction (a longstanding passion for Gbur)"
