Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. When we divide up matter into the smallest possible chunks that it's ...

(Inside Science) — One of the strangest things about quantum mechanics is that a particle can act like a wave. In particular, in a double-slit experiment, individual particles that are shot through a ...

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 ...

Thomas Young’s double-slit experiment is famous for demonstrating the principle of interference. Andrew Murray explains why it’s now possible to carry out an equivalent experiment using lasers that ...

(Nanowerk News) Scientists have long known that electrons are indivisible fundamental particles. Yet surprising new research shows that a weird feature of quantum mechanics can be used to produce ...

In combined theoretical and experimental work, physicists introduce and demonstrate a novel mechanism for electron optics in two-dimensional solid-state systems. The discovery opens up a route to ...
