Quantum

Quantum mechanics, or quantum physics, is a fundamental branch of physics that deals with the behavior of matter and energy at the smallest scales, such as atoms and subatomic particles. Here’s a brief overview of some key concepts and historical milestones in quantum mechanics:

Key Concepts
1. Wave-Particle Duality: Particles such as electrons exhibit both wave-like and particle-like properties. This duality is a cornerstone of quantum mechanics.
2. Quantization: Energy levels in atoms are quantized, meaning electrons can only occupy specific energy levels.
3. Uncertainty Principle: Formulated by Werner Heisenberg, this principle states that it is impossible to simultaneously know both the exact position and momentum of a particle.
4. Superposition: Particles can exist in multiple states at once until they are observed or measured.
5. Entanglement: Particles can become entangled, meaning the state of one particle is directly related to the state of another, no matter the distance between them.

Historical Milestones
- Max Planck (1900): Introduced the concept of quantized energy levels to explain blackbody radiation.
- Albert Einstein (1905): Explained the photoelectric effect, demonstrating that light can be thought of as particles called photons.
- Niels Bohr (1913): Developed the Bohr model of the atom, which introduced quantized electron orbits.
- Erwin Schrödinger (1926): Formulated the Schrödinger equation, which describes how the quantum state of a physical system changes over time.
- Werner Heisenberg (1927): Developed the uncertainty principle.

Quantum mechanics has revolutionized our understanding of the microscopic world and has led to numerous technological advancements, including semiconductors, lasers, and quantum computing¹²³.
