The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it.

A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics ...

Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether in a physics class, in the lab, or in popular science writing, is left ...

Everyone has their favourite example of a trick that reliably gets a certain job done, even if they don’t really understand why. Back in the day, it might have been slapping the top of your television ...

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

World’s Fastest Electron Microscope, Quantum Consciousness and the Origin of Life Host Erika Hamden explores quantum mysteries. We visit a University of Arizona lab where the world’s fastest electron ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." The first step toward quantum gravity, the "holy grail of physics," may ...
