Richard Feynman stated once that "if you think you understand quantum mechanics then you don't understand quantum mechanics". However it is possible to learn how to write and solve the equations of quantum mechanics to get answers that can be verified experimentally.
Bohr.
The classical theory of solids is based on the assumption that atoms are fixed in a lattice structure and do not move. However, quantum mechanics shows that atoms in solids have wave-like properties and do exhibit movement. This discrepancy between classical theory and quantum mechanics makes classical theory inadequate for explaining the behavior of solids at the atomic level.
Niels Bohr was the first to use quantum theory to explain the structure of the atom in his atomic model in 1913. He proposed that electrons orbit the nucleus at specific energy levels, or shells, and that energy is quantized in discrete amounts.
The quantum theory of light explains the results of experiments by treating light as particles called photons. These photons exhibit wave-particle duality, where they can behave as both particles and waves. This quantum nature of light helps explain phenomena such as interference patterns and the photoelectric effect.
The quantum mechanical model is called the quantum theory.
Classical free electron theory could not explain many physical properties. In 1928, Sommerfeld developed a new theory applying quantum mechanical concepts and Fermi-Dirac statistics to the free electrons in the metal. This theory is called quantum free electron theory.

explain planks quantum theory? Planck did not make the whole Quantom thoery. He only made up Quanta. Other scientists helped inprove it over time.

Quantum theory is a fundamental theory in physics that aims to describe the behavior of matter and energy at the smallest scales, such as atoms and subatomic particles. Its purpose is to provide a framework for understanding the nature of particles and interactions at a quantum level, and it has been highly successful in explaining phenomena that classical physics cannot, such as superposition and entanglement.
Some alternative theories to string theory include loop quantum gravity, brane theory, and quantum field theory. These theories propose different ways to explain the fundamental forces and particles in the universe, without relying on the idea of tiny vibrating strings as the building blocks of everything.
The original founder of quantum theory was Max Plank. The basic theory has been improved upon many times but there hasn't been a 'Modern Quantum Theory' that replaces the old.
