"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

The film "Introduction to Holography" explains the principles of holography, focusing on how it differs from traditional photography by creating three-dimensional images. It discusses the role of wave ...

We've learned about light and how to bend it to our will. But what can we LEARN from it? Light is everywhere … but it’s not as predictable as you might think. It’s a wave that travels in straight ...

A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

Artificial intelligence is colliding with a hard physical limit: the energy and heat of today’s silicon-based chips. As ...
