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 ...

The subtlest experiment in quantum mechanics is also one of the simplest: send a stream of particles through two openings in a barrier, and you’ll produce an interference pattern because the particles ...

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

Complementarity A new twist on the double-slit experiment. (Courtesy: Shutterstock/Andrey VP) One of the most counterintuitive concepts in physics – the idea that quantum objects are complementary, ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Quantum mechanics is one of the most ...

About time: Romain Tirole from Imperial College London and colleagues have created a temporal version of the famous double-slit experiment (Courtesy: Thomas Angus, Imperial College London) Thomas ...
