Can an Electron be in Two Places at the Same Time?

Max Planck Researchers in Berlin show that for electrons from nitrogen molecules, the wave-particle character exists simultaneously.

In something akin to a double-slit experiment, scientists at the Fritz Haber Institute of the Max Planck Society, in co-operation with researchers from the California Institute of Technology in Pasadena, California, have shown for the first time that electrons have characteristics of both waves and particles at the same time and in virtually the push of a button can be switched back and forth between these states.
