(Phys.org)—A team of Australian astronomers has conducted an intensive observation of a curious young pulsar to investigate changes in its rotation frequency known as 'glitching'. Located about 910 light years from the ...
(Phys.org) —Researchers in Scotland have devised a way to use the Doppler Effect to discern the spin speed of a rotating object where the object is directly facing the light source. In their paper published in the journal ...
By using a special combination of laser beams as a very fast stirrer, RIKEN physicists have created multiple vortices in a quantum photonic system and tracked their evolution. This system could be used to explore exotic new ...

(PhysOrg.com) -- At 60 million rotations per minute, a two-dimensional sheet of graphene has become the fastest-spinning trapped macroscopic object ever. Graphene is known for its large strength, and it's this strength that ...
Gravitational waves are ripples in space-time that come in many forms. So far, short-duration gravitational wave signals have been observed from colliding black holes and colliding neutron stars, but scientists expect to ...

In conventional milling operations, a workpiece on a table is typically fed past a rotating multi-tooth cutter, and the entire surface is processed by making a series of overlapping passes. This procedure, however, tends ...
