Albert Einstein and Niels Bohr had an ongoing rivalry about the true nature of quantum mechanics, and came up with a thought ...

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 ...

When two or more light waves interact with one another, they result in the formation of different interference patterns. British physicist Thomas Young first demonstrated and explained these patterns ...

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 double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

"These single atoms are like the smallest slits you could possibly build." For over 100 years, quantum physics has taught us that light is both a wave and a particle. Now, researchers at the ...

Even younger: illustration of the new double-slit experiment using resonant inelastic X-ray scattering on an iridium oxide crystal. An intense beam of high-energy X-ray photons (violet) hits two ...
