Students in the class ENGRI 1100: "Lasers and Photonics" engage in hands-on learning and build a laser for an assignment.

The universe comes with a built‑in speed cap, a hard limit that shapes everything from how stars shine to how cause and ...

How would Einstein have reacted to Bell’s theorem and the experimental results derived from it? Alain Aspect’s new ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

The same phenomenon was later confirmed for neutrons, helium atoms, and even large molecules, making matter-wave diffraction ...

For the first time, researchers from Tokyo University of Science have observed wave-like interference patterns from ...

The double slit experiment reveals that observing light changes its behavior, making it act as both a wave and a particle. Person in critical condition after being shot in incident involving Border ...

Charge density waves (CDWs) are ordered, crystal-like patterns in the arrangement of electrons that spontaneously form inside ...

A near-100-year-old debate between the theoretical physicists Albert Einstein and Niels Bohr has finally been settled—and not in the former’s favor. A team of physicists in China have realized a ...

Atom optics is the study of the wave-like properties of beams of atoms. Wave–particle duality — a central principle of quantum mechanics — implies that effects traditionally associated with waves, ...

Here’s what you’ll learn in this story: Time might actually have 3 dimensions. But it also means that the space would actually be one-dimensional, instead of the three dimensions we’re familiar with.
