Modern Physics

Modern physics encompasses advancements in physics made primarily after the early 20th century, revolutionizing our understanding of the universe and its fundamental properties.

Key Theories:

- Quantum Mechanics: Describes the behavior of matter and energy at the atomic and subatomic levels. It introduces concepts like wave-particle duality, quantization of energy, and the uncertainty principle.
- Relativity: Proposed by Albert Einstein, it consists of:
- Special Relativity: Deals with the relationship between space and time for observers in uniform motion.
- General Relativity: Extends special relativity to include gravity and the curvature of spacetime.
- Particle Physics: Explores the fundamental building blocks of matter, including subatomic particles like quarks, leptons, and bosons.
- Cosmology: Studies the origin, evolution, and future of the universe.

Key Concepts:

- Wave-Particle Duality: Matter can exhibit both wave-like and particle-like properties.
- Uncertainty Principle: It is impossible to simultaneously know both the position and momentum of a particle with arbitrary accuracy.
- Quantization: Energy, angular momentum, and other physical quantities exist only in discrete, quantized units.
- Spacetime: A four-dimensional framework that combines space and time into a unified concept.
- Gravitational Waves: Ripples in spacetime caused by the acceleration of massive objects.

Applications:

Modern physics has led to numerous technological advancements, including:

- Lasers and fiber optics
- Transistors and integrated circuits
- Quantum computing and cryptography
- Nuclear energy and particle accelerators
- GPS and satellite navigation
