Japan clocks keep time for 16 billion years
Japanese researchers have built a pair of clocks which they say are so accurate they will lose a second only every 16 billion years—longer than the Earth has been around.

(Phys.org) —Although mass may seem to be a fairly straightforward concept, from a physics perspective it can be much more complex than weighing an object and reading off a number in grams. For instance, an object's mass ...
Nippon Telegraph and Telephone has proposed a method for generating a large-scale entangled quantum state of ultracold atoms in an optical lattice with high fidelity and short operation time, which becomes a resource for ...
