QUANTUM MECHANICS Meaning and
Definition
-
Quantum mechanics, also known as quantum physics, is a branch of physics that deals with the behavior of particles at the atomic and subatomic level. It provides a mathematical framework for understanding the properties and interactions of particles, waves, and energy on extremely small scales.
At its core, quantum mechanics is based on the theory that particles, such as electrons and photons, can exist in multiple states simultaneously, known as superposition. It also postulates that the act of observing or measuring a quantum system can fundamentally change its state, called the collapse of the wavefunction.
One of the most distinctive aspects of quantum mechanics is the concept of wave-particle duality. It describes how particles can exhibit both wave-like and particle-like characteristics, depending on the experiment or observation conducted. This principle is encapsulated by the famous double-slit experiment, where particles display interference patterns similar to waves.
Quantum mechanics introduces the concept of probabilities, represented by wavefunctions, in order to describe the behavior of particles. These wavefunctions can be used to determine the likelihood of finding a particle in a particular state or position.
Applications of quantum mechanics are vast and range from atomic physics to quantum computing and cryptography. Understanding this branch of physics has led to remarkable advancements in various fields, including electronics, materials science, and medical imaging.

Etymology of QUANTUM MECHANICS
The word "quantum mechanics" has its origin in the field of physics, specifically in the early 20th century when new theories were being developed to explain the behavior of matter and energy at the atomic and subatomic levels. The term "quantum" comes from the Latin word "quantus", meaning "how great" or "how much". It was introduced by the German theoretical physicist Max Planck in 1900 when he proposed that energy is quantized into discrete packets, which he called "quanta". This concept revolutionized the understanding of energy and laid the foundation for the development of quantum mechanics. The word "mechanics" refers to the branch of physics that deals with the motion and behavior of physical objects, systems, and forces, so "quantum mechanics" can be understood as the study of the mechanics (behavior and properties) of energy at the quantum (discrete and quantized) level.
