Hula-hooping robots reveal the physics behind keeping rings aloft

Gyrating objects should be hourglass-shaped to hold a hoop steady



Experiments with hula-hooping robots revealed how the hoops stay up, providing some tips for humans aiming to perfect their technique.

To keep a Hula-Hoop aloft, it helps to be in shape - literally.

Experiments with gyrating, hoop-slinging robots have revealed how these spinning rings stay up despite the pull of gravity. 

The shape needs to have “hips” a slope that provides upward force to counteract gravity. And a “waist”  curvature like an hourglass  keeps the hoop from drifting up or down and sliding off.

Inspired by performers near his home in Greenwich Village, applied mathematician Leif Ristroph of New York University began considering the physics of Hula-Hoops. Previous studies, he and colleagues realized, hadn’t explained how the hoop stays aloft. (Ristroph has a track record of tackling quirky physics questions. His group recently investigated what would happen if a lawn sprinkler sucked water in instead of shooting it out.)

So Ristroph and colleagues gave it a whirl. In experiments, a gyrating cylindrical robot couldn’t keep a hoop from sliding down. It was missing the essential upward force, generated when a hoop swings over a sloped shape. But a cone-shaped robot, with a slope but no waistlike curve, also failed. If the hoop began toward the top of the cone, the upward force overpowered gravity, and the hoop would migrate up. If the hoop began toward the bottom, the upward force wasn’t enough to keep it aloft, and it migrated down. But an hourglass-shaped robot kept a hoop steadily aloft.

People should be able to hula-hoop regardless of body shape, by adapting their gyrations based on position changes of the hoop. Indeed, the researchers were able to get a cone-shaped robot to hula-hoop by adjusting the rate of gyration depending on how high the hoop slid.

A correct launch was also essential in the experiments. If the hoop started off too slow, the attempt would fail. In successful sessions, the hoop lined up with the gyrating body, such that the hoop and body always shifted in the same direction. That’s also the best way to launch a hoop, Ristroph says.

Physicists observe a new form of magnetism for the first time

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry " spintronic " memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are not macroscopically magnetized. Now, the MIT team has demonstrated a new form of magnetism , termed "p-wave magnetism." Physicists have long observed that electrons of atoms in regular ferromagnets share the same orientation of "spin," like so many tiny compasses pointing in the same direction. This spin alignment generates a magnetic field, which gives a ferromagnet its inherent magnetism. Electrons belonging to magnetic atoms in an antiferromagnet also have spin, although these spins alternate, with electrons orbiting neighboring atoms aligning their spins antiparalle...

Physicists Catch Light in 'Imaginary Time' in Scientific First

For the first time, researchers have seen how light behaves during a mysterious phenomenon called 'imaginary time '. When you shine light through almost any transparent material, the gridlock of electromagnetic fields that make up the atomic alleys and side streets will add a significant amount of time to each photon's commute. This delay can tell physicists a lot about how light scatters, revealing details about the matrix of material the photons must navigate. Yet until now, one trick up the theorist's sleeve for measuring light's journey invoking imaginary time has not been fully understood in practical terms. An experiment conducted by University of Maryland physicists Isabella Giovannelli and Steven Anlage has now revealed precisely what pulses of microwave radiation (a type of light that exists outside the visible spectrum) do while experiencing imaginary time inside a roundabout of cables. Their work also demonstrates how imaginary numbers can describe a ver...
