Wave-Particle Duality: Why Matter Behaves Like Both
The double-slit experiment shows that particles can spread like waves, arrive like dots, and force us to rethink what reality means.

For Quantum Mechanics, the goal is to understand the principle before memorizing equations. Once the principle is clear, the math becomes a compact language for the same idea.
What to notice
- Identify the system you are studying.
- Track the quantities that stay constant or change predictably.
- Connect the equation to a real motion, field, wave, or measurement.
Physics becomes easier when every formula is treated as a compressed explanation.
