When measuring time, we normally assume that clocks do not affect space and time, and that time can be measured with infinite accuracy at nearby points in space. However, combining quantum mechanics and Einstein's theory ...

(Phys.org)—Werner Heisenberg originally proposed the uncertainty principle in 1927, but his original proposal was somewhat different than how it is interpreted today. As a recent paper in Physical Review Letters explains, ...
Theoretical chemists at Princeton University have pioneered a strategy for modeling quantum friction, or how a particle's environment drags on it, a vexing problem in quantum mechanics since the birth of the field. The study ...
