Quantum mechanics can describe many systems that classical physics cannot. Classical physics can describe many aspects of nature at an ordinary (macroscopic and (optical) microscopic) scale; …

Quantum mechanics can be thought of roughly as the study of physics on very small length scales, although there are also certain macroscopic systems it directly applies to.

Jun 12, 2026 · Quantum mechanics is the fundamental theory in physics that describes nature at the smallest scales of energy and matter. It posits that physical quantities can have discrete values, …

Mar 30, 2025 · Quantum mechanics, or quantum physics, is one of the most profound and enigmatic fields in science. It governs the behavior of matter and energy on the smallest scales—the atomic …

This is the first course in the undergraduate Quantum Physics sequence. It introduces the basic features of quantum mechanics. It covers the experimental basis of quantum physics, introduces wave …

Quantum mechanics is the study of matter and matter's interactions with energy on the scale of atomic and subatomic particles. By contrast, classical physics explains matter and energy only on a scale …

This section contains video lectures for part 1 of the course.

The field of quantum mechanics deals with the most fundamental bits of matter, energy and light and the ways they interact with each other to make up the world.

What is Quantum Mechanics? Quantum mechanics is a branch of physics that deals with the behavior of particles on the smallest scales—such as atoms, electrons, and photons.
