Swinging arms while walking stabilizes torso, conserves energy, and enhances efficiency by utilizing angular momentum principle.

For the first time, physicists have created a "black hole bomb" in the lab, providing evidence for the "Zel’dovich effect" proposed half a century ago. The idea behind the Zel’dovich effect came from ...

(This law of physics, which makes things spin faster as they contract, is called angular momentum ... the head of the plant conservation unit at the Museum of Natural History.

Topics include energy conservation, heat cycles ... Schrodinger's wave mechanics, quantization of angular momentum, and the one-electron atom. Advisors create typical four-year outlines to help you ...

“Conservation groups deplore the ‘Disneyfication ... with pinnacles and crags; and sharp, angular buttresses, bristling with wind and wave polished spires, extend far out into the river.” ...

All this wizardry depends on another form of momentum: the ball’s spin, or more formally, angular momentum. “Watch the really, really, really good [players],” says Goodwin. “They manage to ...
