What is the significance of the Bohr model?
Click to flip
Niels Bohr's model of the atom introduced energy levels, leading to the development of quantum mechanics.
Click to flip
What is Schrödinger's wave equation?
Click to flip
Schrödinger's wave equation describes how the quantum state of a physical system changes over time.

How did Werner Heisenberg contribute to quantum mechanics?
Click to flip
Werner Heisenberg formulated the matrix mechanics for quantum theory and created the Uncertainty Principle.
Click to flip
What is the Copenhagen interpretation?
Click to flip
The Copenhagen interpretation is a philosophical explanation of quantum mechanics developed by Niels Bohr and Werner Heisenberg.

What role did Richard Feynman play in quantum mechanics?
Click to flip
Richard Feynman contributed to quantum electrodynamics (QED) with his formulation using Feynman diagrams.
Click to flip
What did Paul Dirac introduce to quantum mechanics?
Click to flip
Paul Dirac introduced the concept of the Dirac equation, unifying quantum mechanics and relativity.
Click to flip
What was Erwin Schrödinger's contribution to quantum mechanics?
Click to flip
Erwin Schrödinger contributed the wave equation that describes the probability distribution of a particle's position.
Click to flip
What was the EPR paradox?
Click to flip
The EPR paradox, introduced by Einstein, Podolsky, and Rosen, challenged the completeness of quantum mechanics.
Click to flip
What is Bell's Theorem?
Click to flip
Bell's Theorem addresses the contradictions between quantum mechanics and local realism, supporting quantum entanglement.
Click to flip
What was John von Neumann's contribution to quantum mechanics?
Click to flip
John von Neumann formalized the mathematical foundation of quantum mechanics with his work on operator theory.
Click to flip
How has quantum mechanics influenced modern physics?
Click to flip
Quantum mechanics has fundamentally shaped our understanding of atomic, molecular, and particle physics, influencing numerous technological advances.
