Quantum particles take the road most traveled

Quantum particles take the road most traveled

August 6, 2014

Physicists have developed a way to isolate the wacky quantum world and peer into it in a noninvasive way; this allows them to map the path that particles are most likely to take when changing from one state to another. “It’s a great breakthrough in terms of being able to monitor quantum systems,” Andrew Jordan, a physicist at the University of Rochester, who worked on the original theory, told Live Science. “We’re just scratching the surface of the kinds of physics permitted here.”

Quantum mechanics imposes a limit on what we can know about subatomic particles. If physicists measure a particle’s position, they cannot also measure its momentum, so the theory goes. But a new experiment has managed to circumvent this rule—the so-called uncertainty principle—by ascertaining just a little bit about a particle’s position, thus retaining the ability to measure its momentum, too.

Tough economic times can bring out the worst in people, especially when you mix in family, desperation, and the drive to get ahead in business. This is one of the messages in Bluff City Pawn, a new novel by professor Stephen Schottenfeld, which hits bookstores this week.

What really stoked the spirit of 1776

August 4, 2014

Toward the end of his long life, John Adams famously defined the “radical change” that constituted “the real American Revolution” as the loss of “an habitual affection for England.” Well aware of how easily that revolution might have gone awry, he asked, Whence unity out of diversity? Thomas P. Slaughter, the most recent in a long line of talented men and women who have taken up the challenge posed by Adams, seeks an answer in a return to basics.

As a quantum state collapses, it will follow a path known as a quantum trajectory. In a new paper featured this week on the cover of Nature, scientists have shown that it is possible to track these quantum trajectories and compare them to a theory, recently developed by University of Rochester physicists, for predicting the most likely path a system will take.

Scientists discover why the Appalachian mountain chain bends

Scientists discover why the Appalachian mountain chain bends

Scientists had known that volcanic rock ran under the chain, but “what we didn’t understand was the size of the structure or its implications for mountain-building processes,” a University of Rochester researcher explains.

When temperatures drop, newly-discovered process helps fruit flies cope

July 21, 2014

Rochester biologist Michael Welte and his team made their discovery while studying the internal mechanisms of the egg cell of the fruit fly, known as Drosophila. What keeps the assembly line functioning—based on the new research—is a protein called Klar.

Bend in Appalachian mountain chain finally explained

July 18, 2014

Rochester researchers now know what causes the bend in the otherwise straight line of the Appalachian Mountains, and this new understanding of the region’s underlying structures could inform debates over the practice of hyrdrofracking.
