(Phys.org) —Given all the weird things that can occur in quantum mechanics—from entanglement to superposition to teleportation—not much seems surprising in the quantum world. Nevertheless, a new finding that an object's ...
For the past eight years, two French researchers have been bouncing droplets around a vibrating oil bath and observing their unique behaviour. What sounds like a high-school experiment has in fact provided the first ever ...
