(Phys.org) —Last week saw the physics community buzzing as a physicist suggested that the speed of light might be slower than thought—James Franson of the University of Maryland posted an article in a peer-review journal ...
(PhysOrg.com) -- Einstein infamously dismissed quantum entanglement as spooky action at a distance and quantum uncertainty with his quip that God does not play dice with the universe. Aside from revealing his conceptual prejudices, ...
Atomic clocks are the most precise timekeepers in the world. These exquisite instruments use lasers to measure the vibrations of atoms, which oscillate at a constant frequency, like many microscopic pendulums swinging in ...
