(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 ...
A couple years ago, researchers introduced a new material that they said could make any object invisible to both radar and the human eye. Invisibility cloaking would have a major impact on defense technology, they explained, ...
