Quantum MechanicsQuantum mechanics is the science of subatomic particles and their behavioral patterns observed in nature. As the foundations of scientific knowledge approached the beginning of the 20th century, problems began to arise because classical physical ideas were not able to explain the observed behavior of subatomic particles. In 1913, Danish physicist Neils Bohr proposed a successful quantum model of the atom that began the process of a more defined understanding of its subatomic particles. At the beginning of the 20th century, it was accepted that light propagated both in the form of waves and particles. The reason why light appears to act as a wave and a particle is that we notice the accumulation of many light particles distributed according to the probabilities of each particle's location. In 1923, Louis De Broglie hypothesized that subatomic particles exhibit wave and particle properties for the same reason. The success of these theories inspired physicists to develop a way to describe the behavior of subatomic phenomena in terms of waves and particles using mathematics. Newton's laws, the basis of classical physical ideas, provide precise information about the location of an object. at any future time. Classical physics assumes that all particle collisions and locations can be measured at the same time. The dual wave-particle nature of electrons ran counter to such beliefs. In a changing environment, much like the nature of the electron, the classical physical attributes of position and momentum are ephemeral phenomena. No atomic particle can possess both of these properties at the same time. An electron cannot be observed without changing state. Simultaneously measuring ...... middle of paper ...... gives equivalent results - mathematically, it was the same theory. Together, the two theories formed a logical interpretation of the physical meaning of quantum mechanics, known as the "Copenhagen interpretation". The scientists, nourished by the Copenhagen doctrine and the new quantum mechanics, formed a new dominant generation of physicists. With the help of modern quantum physics, we can talk about more attributes, such as mass, charge, wave functions, and the uncertainty principle in describing the behavior of electrons. But, as Bohr's Copenhagen interpretation suggests, our quantum theories are simply human-made generalizations formulated to account for our observations. Quantum mechanics fails to provide deterministic, single-valued solutions to any problem. The true and precise prediction of the behavior of subatomic particles remains to be discovered.
