This paper tells that Quantum Mechanics is a branch of physics which mainly relates to the nature of the atomic particles. The theories of Quantum Mechanics started to confront inconsistency when they were solely used with the principles laid down by Newtonian physics. One of the observations revolves around that light that the atoms can absorb and emit respectively. An example of hydrogen atoms can be taken here which can absorb energy when the light has the wavelength of 656.3 nm, 434.9 nm or 410.2 nm. However, in the latter half of the nineteenth century, it was put forward that an electron should radiate at all wavelengths given and should, therefore, fall in the nucleus after losing energy.

This theory was later on proved to be false by Berliner Plank in 1900 when he put forward that energy can only be emitted in definable packets. Another scientist, Erwin Schrodinger, was that the electron in hydrogen is analogous to a string in a guitar. The electron would have a distinct speed at which it would emit light like a guitar emits a tone along with overtones.

Using this theory as a base model, a wave equation was developed which would correctly calculate the wavelength of light transmitted by the hydrogen electron. Physicists Born, Heisenberg and Jordan worked on finding the momentum of an electron with respect to its position in an atom. The position of the electron in an atom. They believed that the values could not have been calculated because in reality only the light emitted by the electrons could be observed and hence it could be different from what the theory of Newton puts forward.

They maintained that the values of momentum and position could be calculated using mathematical constructs in matrices and matrix algebra. The two theories were mathematically equalvaliant since they both were derived from the same principal. Both groups of research scientists maintained their stance and that is when the genius of John Von Neumann stepped in 1926 to work on reconciling both the theories of quantum mechanics and advancing it to the level that we apply today.
