Quantum timekeeping
Recent advances in controlling the quantum behavior of particles have inspired physicists to dream of a global clock that would tell the same time everywhere. It would be hundreds of times as accurate as current atomic clocks.

Einstein was wrong about spooky quantum entanglement
Einstein’s biggest blunder wasn’t about vacuum energy in space, but in confusing people about quantum entanglement.

History affects superfluid’s flow, study shows
The speed to stop the stirring motion can be slower than what was need to set the fluid spinning in the first place, which shows that what happens to the current state of the superatom depends on what it has already experienced.

Atomic clock sets world records for precision, stability
The strontium atomic clock is about 50 percent more precise than the previous record holder made of a single charged aluminum atom and rivals the ytterbium atomic clock for the title of most stable.

Gell-Mann, Hartle spin a quantum narrative about reality
The “consistent histories” approach to quantum physics removes any role for people in creating “quasiclassical” reality.

‘QBists’ tackle quantum problems by adding a subjective aspect to science
Advocates of a program called “Quantum Bayesianism” take a subjective approach to resolving the paradoxes of quantum physics.

Electrons’ roundness frustrates researchers
Experiment finds no signs of asymmetry, which would point to undiscovered particles.
