As most of you know, I’m a big Harry Potter fan, having read all the books and seen all the films. The books are so well written and the special effects so good that you almost feel sometimes that you are there alongside Harry, enjoying his many adventures. One of the boy wizard’s most famous “props” is his invisibility cloak which allows him to roam Hogwarts’ library in the middle of the night, without being discovered.
The Harry Potter stories are fiction but it seems that fiction is about to become reality as scientists at an Indiana University have discovered how to create a real-life invisibility cloak. Apparently only last year, physicists discovered the complex mathematical equations for bending light around objects to make them invisible. University engineers have now used these calculations to create a device that could eventually make objects the size of a plane just disappear into thin air. If the university can secure funding, a prototype device could be up and running within two to three years. Fascinating stuff!
