What is Quantum Mechanics (or Modern Physics) ?

Quantum Mechanics

Quantum Mechanics (or Modern Physics) is a branch of physics that describes the behavior of matter and energy at the smallest scales, such as atoms and subatomic particles.It is based on quantum theory and special theory of relativity. 

The four sectors of quantum mechanics are:

Quantization of physical properties,Quantum entanglement,Uncertainty principle and Wave-particle duality(de Broglie hypothesis)

Key Principles Of Quantum Mechanics are:

• Wave-Particle Duality(wave-like and particle-like behavior)
• Uncertainty Principle( impossibility to know conjugate properties e.g. position and momentum, simultaneously with infinite precision)
• Superposition of states (Quantum objects can exist in multiple states simultaneously)
• Entanglement of states( state of one quantum object is dependent on the state of the other, even distant object)
• Quantization(absorption and emission of energy in small packets named quanta)
