ElectricSteve writes "Metamaterials are man-made substances designed to do some very weird things that natural materials don't. The path of a beam of light through a natural material like glass is predictable, but scientists from the California Institute of Technology have engineered an optical material that bends light in the wrong direction. This new negative-index metamaterial (NIM) could have several valuable uses including invisibility cloaking, superlensing (imaging nano-scale objects using visible light), and improved light collection in solar cells."
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
