Scientist presents “invisibility cloak” in California

At a US tech conference, a scientist unveiled a small ‘invisibility cloak’ that causes objects behind it to mysteriously ‘disappear’ – similar to the magic garment worn by Harry Potter at the Hogwarts School of Witchcraft and Wizardry.

The device more closely resembles a small box than a cloak, but makes objects behind it appear to completely vanish. Using science to bend light around an object, the inventor found a way to conceal items placed behind his device.

Dr. Baile Zhang, an assistant professor of physics at Nanyang Technological University in Singapore, unveiled his invention at a TED conference in Long Beach, Calif, where he explained that he constructed the invisibility machine “just for fun” after coming up with the idea in 2010.

But his hobby quickly became known as a technological breakthrough: what the 31-year-old electrical engineer constructed for ‘fun’ has instilled excitement among those hoping that the technology can be used to create a life-sized invisibility cloak.

But creating a life-sized cloak would prove more difficult: Dr. Zhang’s disappearing box was developed by attaching two pieces of calcite, a carbonate mineral that can bend light. While it is possible to create a larger version of his invention, it would not be feasible to create a garment out of the dense, colorless mineral.

For now, the scientist is working on creating a larger version of the invisibility box, one that is “as large as possible”, he told Boing Boing.

Still, the object has become the talk of the conference. A YouTube video shows Zhang placing the ‘cloak’ in front of a Post-it notepad, causing a section of it to instantly disappear. The box itself remains near-invisible as it flawlessly conceals the tiny object.


seems to if they are showing us that far has it really progressed in development?
