Heisenberg limit gets a meaningful update

One of the cornerstones of quantum theory is a fundamental limit to the precision with which we can know certain pairs of physical quantities, such as position and momentum. For quantum theoretical treatments, this uncertainty ...

The Large Synoptic Survey Telescope could find more of Earth's transient moons

It is a well-known astronomical convention that Earth has only one natural satellite, which is known (somewhat uncreatively) as "the moon." However, astronomers have known for a little over a decade that Earth also has a ...
