Harry Potter and his cloak of invisibility - which you can't see obviously
Invisibility has been a staple of science fiction, (and my own personal fantasies), for decades and in recent years we’ve watched as fiction edges ever closer to reality through the use of metamaterials. The problem with most of the devices currently being researched however, is that since they totally encompass the object being rendered invisible, they are also rendered blind as well, which kind of defeats the purpose. But a team from Hong Kong’s University of Science and Technology believes they have come up with an answer to this problem and that it is indeed possible to create a cloaking device that would be able to render an object invisible without encompassing it.
