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 ...

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...

The famous double slit experiment shows that particles can travel on two paths at the same time -- but only by looking at a lot of particles and analysing the results statistically. Now a ...

The Arduino Science Kit Physics Lab is the first official kit designed for middle schoolers, who can look forward to experimenting just like real scientists – coming up with their own hypotheses, ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. This article is more than 10 years old. A couple of weeks ago, I listed ...

Researchers replicated the classic double slit experiment using lasers, but their slits are in time not space. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

Can two versions of reality exist at the same time? Physicists say they can — at the quantum level, that is. Researchers recently conducted experiments to answer a decades-old theoretical physics ...

In quantum mechanics particles can behave as waves and take many paths through an experiment. It requires only combinations of pairs of paths, rather than three or more, to determine the probability ...

Physicists should rethink interference experiments to reveal whether or not general relativity follows classical theory, argue Chiara Marletto and Vlatko Vedral. Sixty years ago, physicists ...
