Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

Several weeks ago I picked up “The Elegant Universe” because I thought it would have information on The Ultimate Theory. Soon afterwards, I picked up “How to Teach Physics To Your Dog” in order to get ...

A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

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 ...

MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings demonstrate, with atomic-level precision, the dual yet evasive nature of ...
