Wiggling robots reveal the physics of how Hula-Hoops stay up
Newbies should swing their Hula-Hoops fast and in line with their bodies, the new findings suggest.

If trees could act as natural antennas, one physicist proposes that they just might pick up signals of hard-to-spot ultra-high energy neutrinos.
Experiments with a floating sprinkler revealed the surprisingly complex physics behind a simple question.
About 10 percent of the fruit in a tilted market display can be removed before it will crash down, computer models show.
The force of friction always acts to slow things down. It depends on just two factors: the surfaces and how hard they press together.
Individual seeds on a dandelion release most easily in response to winds from a specific direction. As the wind shifts, this scatters the seeds widely.
Long-necked plesiosaurs were thought to be slow swimmers. But new research suggests the animals’ large size helped them overcome water resistance.
When an object experiences a force, its change in motion — or acceleration — depends on its mass.
This thin, flexible and lightweight loudspeaker could reduce noise in loud spaces. It also might enable listeners to experience sound in new ways.
Two types of friction help determine how quickly a line of dominoes collapses, computer modeling shows.
