(Phys.org) —A team of researchers working in Australia has built a tractor beam that bests the distance of other efforts a hundred fold—and it can both push and pull objects. In their paper published in the journal Nature ...
In nature, waves – such as those in the ocean – begin as local oscillations in the water that spread out, ripple fashion, from their point of origin. But fans of Star Trek will recall a different sort of wave pattern: ...
