Wave—particle duality has been one of the guiding concepts in the development of modern physics. Even though duality has been extensively studied, the concept possessing multiple definitions has not ...

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre world in which an object can act like both waves and particles, and behave ...

“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe.

Absolute zero is the lowest theoretical temperature, which scientists have defined as minus 459.67 degrees Fahrenheit (minus 273.15 degrees Celsius). That's even colder than outer space. So far, ...

Schematic of the MIT experiment: Two single atoms floating in a vacuum chamber are illuminated by a laser beam and act as the two slits. The interference of the scattered light is recorded with a ...

Scientists have long grappled with a fundamental question: what exactly is light? Is it a wave, flowing like ripples across water, or is it made up of tiny particles, like miniature paintballs zipping ...

Photons are particles of light, or waves, or something like that, right? [Mithuna Yoganathan] explains this conundrum in more detail than you probably got in your high school physics class. While ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...
