Scientists at Columbia University have found that electron waves can remain trapped near atomic defects in a metal, despite ...

Richard Feynman, one of the greatest physicists of the 20th century, once said something that should either comfort or terrify you: “Nobody understands quantum mechanics.” This wasn’t a confession of ...

Thomas Young, born 250 years ago this week, was a polymath who made seminal contributions in fields from physics to Egyptology. But perhaps his most enduring legacy is proving Isaac Newton wrong about ...

A multiwavelength laser source known as a frequency comb provides a new technique for atom interferometry, potentially leading to new tests of fundamental physics. Interfering with atoms. Two ...
