The Copenhagen Interpretation stands as one of the most influential and debated perspectives in the field of quantum mechanics. Emerging from the collaborative efforts of physicists Niels Bohr and Werner Heisenberg during the early 20th century, this interpretation provided a conceptual framework to make sense of the strange and counterintuitive behavior observed at the quantum level. At its core, the Copenhagen Interpretation asserts that physical systems do not have definite properties until they are measured, and that the act of measurement plays a fundamental role in shaping the physical reality we observe. This essay delves into the origins, principles, and implications of the Copenhagen Interpretation, explores its philosophical underpinnings, and evaluates the criticisms and alternatives that have emerged in response. Historical Context and Origins Quantum mechanics arose at the turn of the 20th century as classical physics began to fail in explaining certain phenomen...
