Quantum mechanics tells us that a particle can never be perfectly still. But how precisely can it be oriented? A research team at the University of Vienna, together with colleagues at TU Wien and Ulm ...
A detailed experimental analysis explains the forces by which a spinning magnet can cause another magnet to levitate in midair. An experiment with off-the-shelf components uses a magnet glued to the ...
More than half a century ago, Sir Roger Penrose envisioned a scenario in which energy could be extracted from a black hole spinning at extreme speeds. He proposed that a particle entering its ...
Researchers detected the effect of rotating a crystal on the spin of an embedded particle, a result that could lead to ultrasensitive rotation sensors. Spinning diamond. A small slab of diamond is ...
Circular thinking: light a ring laser has been used to measure the Earth’s rotation. (Courtesy: iStock/amtitus) A gyroscope sensitive enough to detect Earth’s rotation has been created using a ...
