From the article. A team of scientists has succeeded in putting an object large enough to be visible to the naked eye into a mixed quantum state of moving and not moving. According to quantum theory, particles act as waves rather than point masses on very small scales. This has dozens of bizarre consequences: it is impossible to know a particle's exact position and velocity through space, yet it is possible for the same particle to be doing two contradictory things simultaneously. Through a phenomenon known as 'superposition' a particle can be moving and stationary at the same time — at least until an outside force acts on it. Then it instantly chooses one of the two contradictory positions.
