Figure 1: Low-amplitude mosquito kinematics. Our simulations of forces, torques, power expenditure and flow fields show great consistency, with the aerodynamic features being entirely robust to the ...
Water waves can gain energy when they scatter from a whirlpool-like vortex. That is the conclusion of physicists in Brazil, Canada and the UK, who are the first to observe a phenomenon called ...
Beams of electromagnetic radiation can be used to detect the rotation of distant objects if they have orbital angular momentum – known as ‘vortex waves’. It involves exploiting a rotational form of ...
(PhysOrg.com) -- New analysis of images taken by ESA's Venus Express orbiter has revealed surprising details about the remarkable, shape-shifting collar of clouds that swirls around the planet's South ...
The Arctic witnessed a meteorological phenomenon this month when a sudden stratospheric warming event compelled the polar vortex to deviate from its usual path, inverting its rotation. Instead of its ...
What do smoke rings, tornadoes and the Great Red Spot of Jupiter have in common? They are all examples of vortices, regions within a fluid (liquid, gas or plasma) where the flow spins around an ...
You may not realize it, but the Doppler effect is everywhere in our lives, from tracking the speed of cars with radar to locating satellites in the sky. It's all about how waves change their frequency ...
WASHINGTON, D.C. Oct. 15, 2013 -- What do smoke rings, tornadoes and the Great Red Spot of Jupiter have in common? They are all examples of vortices, regions within a fluid (liquid, gas or plasma) ...
