Invisibility Cloak

The Harry Potter invisibility cloak is now a reality.

Dubbed Quantum Stealth, the material bends light waves - sans batteries, mirrors, or cameras. The cloak wearer is invisible to the naked eye and to thermal and infrared imaging as well.

Breakthrough of 2010: First Quantum Machine

While both verifiable, the two big fields of physics - classical mechanics and quantum mechanics - seemed incompatible ... until now.

Before 2010, all human-made objects moved according to the laws of classical mechanics. In March, researchers designed a gadget that moves according to quantum mechanics (governing the behavior of tiny things like atoms).

Science has called this discovery the most significant scientific advance of 2010.

Here's a video explanation.
