Imagine hearing great, departed pianists play again today, just as they would in person. John Q. Walker demonstrates how recordings can be analyzed for precise keystrokes and pedal motions, then played back on computer-controlled grand...

Why you can’t clone Schrödinger’s cat: this video presents the full proof of the “No Cloning” Theorem in Quantum Mechanics – without any fancy math! (stereotypical qubit has been replaced with...
