Quantum Mechanics is the branch of physics that studies the behavior of matter and energy at the scale of atoms and subatomic particles. While classical physics explains the motion of planets and falling apples, quantum mechanics reveals a world that is often counterintuitive and strange. The Core Principles Wave-Particle Duality
Proposed by Werner Heisenberg, this principle states that you cannot simultaneously know the exact position and momentum of a particle. The more precisely you measure where a particle is, the less precisely you can know how fast it is moving. Superposition and Entanglement INTRODUCTION TO QUANTUM MECHANICS
Two particles can become linked so that the state of one instantly influences the state of the other, regardless of the distance between them. Einstein called this "spooky action at a distance." Why It Matters Quantum Mechanics is the branch of physics that
💡 Quantum mechanics tells us that at the most fundamental level, the universe is governed by probability rather than absolute certainty. To make this article more useful for your specific needs: Should I add practice problems or formulas for a student? The more precisely you measure where a particle
A particle can exist in multiple states at once until it is observed. This is famously illustrated by Schrödinger’s Cat.
