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'.
