Understanding Quantum Physics
Introduction
Quantum physics is the study of the very small, like atoms and subatomic particles.
It's a fascinating field that explains how the universe works at its most
fundamental level. Quantum physics is responsible for many technologies we use
today, like computers, lasers, and nuclear power plants.

Key Concepts
Wave-Particle Duality

One of the most important concepts in quantum physics is wave-particle duality.
This means that particles, like electrons, can behave like both waves and
particles. This is demonstrated in the double-slit experiment, where electrons fired
at a wall with two slits create an interference pattern, which is a characteristic of
waves.

Wave Function

The wave function is a mathematical description of a particle's state. It contains all
the information about the particle, like its position and momentum. The wave
function is not a real physical wave, but an abstract mathematical object. To get
real-world properties, like position or momentum, we have to perform
mathematical operations on the wave function.

Probability Distribution

The wave function gives us a probability distribution, which tells us the likelihood
of finding a particle in a particular location. This means that we can't know a
particle's position with infinite precision.

Measurement Problem

The measurement problem is a fundamental problem in quantum physics. It asks
how the wave function collapses into a definite state when we make a
measurement. We don't have a complete understanding of how this happens.

Superposition

Superposition is the idea that a particle can be in multiple states at the same
time. This is because the wave function can be a combination of different
waves. We saw this in the double-slit experiment, where the electron wave goes
through both slits at the same time.
