Quantum mechanics is a field of physics that investigates the behavior of matter and energy on atomic and subatomic scales. In contrast to classical physics, which dictates the movement of larger bodies, quantum mechanics functions in a domain where particles act in unusual and counterintuitive manners. A key idea in quantum mechanics is wave-particle duality, which proposes that particles such as electrons and photons can behave as both particles and waves based on the observation method used. This duality fundamentally questions our comprehension of the essence of light and matter.

Another important concept is Heisenberg’s uncertainty principle, which asserts that one cannot precisely know both the position and momentum of a particle at the same time. The more precisely you assess one, the less precisely you can assess the other. This uncertainty arises not from limitations in measurement instruments but is an intrinsic characteristic of the particles.

Quantum superposition is an essential principle, indicating that particles can be in several states simultaneously. The particle “collapses” into a single state only when it is observed. This is famously demonstrated by Schrödinger’s cat thought experiment, in which a cat is regarded as both alive and dead until it is observed. Quantum entanglement also explains how particles can become connected such that the condition of one particle immediately influences the condition of another, regardless of the large distances between them.

While these principles may appear odd, quantum mechanics is utilized in everyday technologies, including semiconductors, MRI devices, and lasers. In addition, it establishes the basis for new areas such as quantum computing, which aims to transform computing capabilities. Although it is intricate, quantum mechanics is essential for comprehending the universe at its most basic level
