What really happens in the quantum world? In this conversation, physicist Sean Carroll explores some of the deepest mysteries ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction. Yet daily life ...

Does quantum mechanics really reflect nature in its truest form, or is it just our imprecise way of describing the weird properties of the very small? A famous test that can help answer this question ...

Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can be in more than one state at once. When a particle's state is measured, ...

From the vantage point of quantum physics, the universe may in some ways be fundamentally unknowable. In quantum physics, every object, such as an electron, is matched to a mathematical formula called ...

Here’s what you’ll learn when reading this story: Quantum mechanics is known in popular culture primarily for its weirdness. While, in classical physics, objects have a definite position and state at ...

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

A hundred years ago this week, at the height of the quantum revolution, Austrian physicist Erwin Schrödinger submitted a manuscript for publication. Its centerpiece was an innocuous-looking equation ...
