Best of Last Week – Setting a quantum speed limit, slowing the speed of light and turning back the aging clock

(—It was a very busy week for physics research. A team of scientists has set a quantum speed limit—the group at the University of California found a way to prove a fundamental relationship between energy and time, the flip side of the Heisenberg uncertainty principle. And researchers at MIT unveiled a new analysis that shows a way to self-propel subatomic particles—it is one of the new ways scientists have found to “trick” the traditional laws of physics. Another was demonstrated by a team of physicists at the University of Glasgow as they found a new way to slow the speed of light—by running a laser beam through a mask causing a change in the shape of photons. Meanwhile, another combined team of researchers in Europe found a way to demonstrate that atoms can be in two places at the same time—they pulled an atom in two directions at once, giving a hint that quantum mechanics may hold for large objects. —> Read More Here
