From swirling oil paints to the grin of a Cheshire cat, this Physics World Stories episode brings quantum science to life ...

In some ways, death doesn't exist in quantum mechanics. ... Then, in 1970, a small circle of physicists rediscovered it and coaxed Everett into elucidating his ideas.

There’s obviously some deep principle of quantum mechanics at play here, ... A very slightly better way to celebrate the ratio of a circle’s circumference to its diameter is July 22nd, ...

Quantum mechanics, or quantum physics, is the body of scientific laws that describe the wacky behavior of photons, electrons and the other subatomic particles that make up the universe.

In quantum mechanics, particles’ positions, velocities and other qualities are described by probabilities, not certainties. That means particles can be suspended in a weird purgatory known as a ...

Quantum entanglement is a quantum mechanical phenomenon in which the quantum states of two or more objects have to be described with reference to each other, even though the individual objects may ...

In quantum mechanics, values such as position, momentum, energy and spin are "quantized," which means they can only take on certain discrete values rather than any value.
