A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

The parity-identification problem fits naturally into this landscape. Parity is a global property, insensitive to most local details. In this respect, it resembles many other quantities studied in ...

Picture Victorian London, but its skies are filled with airships. Steam-powered robots crowd the streets, mingling with people in top hats and petticoats. That type of retrofuturistic mash-up is the ...

A new room-temperature quantum device developed at Stanford uses twisted light and advanced materials to link photons and ...

One of the most striking features of quantum physics is that certain properties cannot be measured at the same time. Every measurement may inevitably affect the object's physical state being ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

Here’s what you’ll learn in this story: The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it. While most physicists agree that human ...

I like to go running in my free time. I’m not an especially fast jogger, but I think I could keep up with a tortoise. According to Zeno of Elea, an ancient Greek scholar who lived around 450 B.C.E., ...

For decades, researchers have used that green fluorescent protein and similar molecules to light up the field of biology, tracking what’s happening inside cells. Now these ubiquitous tools are ...
