Answer:
It is not clear . Some books advocates Max plank, some Neils Bohr , some Erwin Schrodinger and some even say Heisenberg . Definitely Max Planck. No Doubt !
Answer:
Max Planck was the first to use ideas of quantum theory when he solved the "ultraviolet catastrophe" in December of 1900. At the time, however, neither he nor the vast majority of the scientific community noticed the implications of his "quantization of energy."
In 1905, Albert Einstein published a paper on the photoelectric effect in which he described energy transfer via light in the form of photons. He was one of the first physicists to acknowledge that particles could only obtain certain discrete energies.
Many textbooks, however, will credit Max Planck as the "father of quantum theory."
Max Planck is not only the father of quantum mechanics.Those who took part in the discovery of quantum mechanics are known as founding fathers and they are Planck, Einstein, Bohr, Heisenberg, Born,Jordan, Pauli, Fermi, Schrodinger, Dirac, de Broglie, Bose. They all made notable contributions.
Note: Quantum mechanics is not only the invention of one or two scientists.
Probably Werner Heisenberg, because he came up with the uncertainty principle. The uncertainty principle (look further into this) essentially suggested that the way particles--particularly electrons--interact in the physical world is all based on probability. This but quantum mechanics away form all of the other sciences at that time. Thus making Heisenberg be the father, because he came up with the Uncertainty Principle.

The mixed state in quantum mechanics is the statistical ensemble of the pure states.
Classical Mechanics and Wave Theory.
There is no reasonable alternative to quantum mechanics, at least not something that can even compare with the predictive power and experimental accuracy as quantum theory. If you want to make predictions about things happening at small scales you cannot do without quantum mechanics. Also note that certain models which are now considered as possible theories of everything (e.g. string theory) all expand upon quantum mechanics, they do not make quantum mechanics invalid or unnecessary.
This is the title of a book that teaches how to perform the calculations of Quantum Mechanics, in very simple easy to follow terms.
Because light waves and radioactive decay are some of the key factors that lead to the development of Quantum Mechanics. Quantum mechanics is also our best apparatus for describing and predicting those phenomena.
Principles of Quantum Mechanics was created in 1930.
The distinction is sometimes made to distinguish normal quantum mechanics (which does not incorporate special relativity) and quantum field theory (relativistic quantum mechanics). Since we know special relativity is correct it is the relativistic form of quantum mechanics which is true, but non-relativistic quantum mechanics is still used, because it is a good approximation at low energies and it is much simpler. Physics students typically study regular quantum mechanics before moving on to quantum field theory.
The concepts of quantum mechanics were not explored until the 20th century. Newton only lived into the 18th century, so Newton did no work on quantum mechanics.
The mixed state in quantum mechanics is the statistical ensemble of the pure states.
Quantum Mechanics "replaced" Classical Mechanics in particle physics in mid-1930s.
It is also called wave mechanics because quantum mechanics governed by Schrodinger's wave equation in it's wave-formulation.
Classical Mechanics and Wave Theory.
Quantum mechanics is a separate branch of physics. It is a general term given to all quantum physics. There are many subbranches, for example Quantum chronodynamics which describes the strong nuclear interaction.

I am not aware of it "not being explained". I would guess that you can explain the relevant aspects with quantum mechanics.
