This article is an extended version of the article “The double-slit experiment” that appeared in the September 2002 issue of Physics World (p15). It has been further extended to include three letters ...

BERKELEY, CA -- The big world of classical physics mostly seems sensible: waves are waves and particles are particles, and the moon rises whether anyone watches or not. The tiny quantum world is ...

Physicists using the SOLEIL synchrotron in France are the closest yet to realizing a thought experiment first proposed in 1927 by Albert Einstein. A variation on the much-loved double-slit experiment, ...

The precise methodology of Richard Feynman's famous double-slit thought-experiment – a cornerstone of quantum mechanics that showed how electrons behave as both a particle and a wave – has been ...

I want to tell you about one of the most beautiful ideas that I know. It’s a physics experiment, and it's beautiful because in one elegant stroke, it expands our consciousness, forcing us to realize ...

There is some misunderstanding about interference in the double-slit experiment. The electron doesn’t interfere with the next electron, but with itself. Receive a weekly dose of discovery in your ...
