(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 have modeled the fluid dynamics of multi-rotor wind turbines, and how they interact in wind farms. The research demonstrates a clear advantage for a turbine model with four rotors.

Physicists have proposed an entirely new way to test the quantum superposition principle—the idea that a quantum object can exist in multiple states at the same time. The new test is based on examining the quantum rotation ...
(PhysOrg.com) -- Whale researchers have known for some time that humpback whales are able to perform feats of underwater acrobatics that belie their huge size and that some of that ability is partly due to the bumps they ...
(PhysOrg.com) -- Normally, when a helicopter loses power in flight due to engine failure, the pilot reverts to using a technique called autorotation to avoid crashing. What happens is the rotors keep spinning automatically ...
A research team led by the Technical University of Munich (TUM) has succeeded for the first time in producing a molecular electric motor using the DNA origami method. The tiny machine made of genetic material self-assembles ...
