one is called Einsteins Box which goes as follows. Consider a box filled with light. The box has a shutter, which opens and quickly closes by a clock at a precise time, and some of the light escapes. We can set the clock so that the time that the energy escapes is known. To measure the amount of energy that leaves, Einstein proposed weighing the box just after the emission. The missing energy will lessen the weight of the box. If the box is mounted on a scale, it is naively possible to adjust the parameters so that the uncertainty principle is violated. After Bohr considered this for a while, he realized if the energy of the box is known, then the time in which the shutter opens and closes is uncertain because the presence of a gravitational field alters time slightly and can account for the uncertainty that is required in this situation.

Einstein never disproved the uncertainty principle which he despised, and the ironic thing about all this is Einstein is credited to be the father of quantum mechanics and dynamics even though he did not believe in its accuracy. Even though one of our greatest scientist disapproved this branch of physics, it is thought to be correct for most scientist. It is still an active area of research and development and is now an important branch to explain the natural world. So the question seems to be answered, god might play dice.
