When placed in an acoustic field, small objects experience a net force that can be used to levitate the objects in air. In a new study, researchers have experimentally demonstrated the acoustic levitation of a 50-mm (2-inch) ...
(PhysOrg.com) -- In investigating the behavior of large-amplitude standing water waves, mathematician Jon Wilkening of the University of California, Berkeley, has discovered that the waves’ behavior cannot be explained ...
(PhysOrg.com) -- By precisely shaking a container of shallow water, researchers have observed wave behavior that has never been seen before. In a new study, Jean Rajchenbach, Alphonse Leroux, and Didier Clamond of the University ...
(PhysOrg.com) -- As dough flies through the air, transforming from a ball into a disk in the chef’s experienced hands, pizza tossing can definitely be thought of as an art. But, as a recent study shows, pizza tossing is ...
Researchers at The University of Manchester in the UK, led by Dr. Artem Mishchenko, Prof Volodya Fal'ko and Prof Andre Geim, have discovered the quantum Hall effect in bulk graphite—a layered crystal consisting of stacked ...
