Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the originating era?Early 20th century, with foundational work from 1900 to the 1930s
2. What is the key interpretations?Copenhagen Interpretation, Many-Worlds Interpretation, Bohmian Mechanics
3. Why do particles sometimes act like waves?Because of wave‑particle duality, a particle can show wave-like behavior, such as bending around corners, when we set up the right experiment, but it can also act like a tiny ball when it hits a detector.
4. How does quantum superposition work?Superposition means a particle can be in many states at once until we look at it. When we measure it, the wave function collapses and the particle chooses one definite state.

Quantum Field Theory: A theoretical framework that combines quantum mechanics with special relativity, describing particles as excitations of fields.
Wave Function Collapse: The instantaneous transition of a quantum system from a superposition of states to a single definite state upon measurement.
Quantum Tunneling: The phenomenon where a quantum particle can pass through a potential energy barrier, even if it lacks sufficient classical energy to do so.
