Quantum mechanics is the mathematical description of matter on an atomic and subatomic scale. It is focused around the wavefunction of a system. Wave functions contain all information about the system such as: momentum, position, angular momentum, energy, etc. This information can only be known by its respective probability distributions. The basis of quantum mechanics in the wave mechanics formulation is the Schrodinger equation, which has two forms: the time-dependent and the time-independent.
Quantum mechanics is a branch of mechanics concerned with mathematical modelling of the interaction and motion of subatomic particles.

∙ 12y agoQuantum mechanics is a collection of several mathematical models of reality describing interactions of small particles. Nobody really understands why it works, but experimental evidence has verified its predictions to more digits of precision than any other scientific theory has ever been verified.

What is a mixed state in quantum mechanics?
The mixed state in quantum mechanics is the statistical ensemble of the pure states.
What is the alternative to quantum mechanics?
Classical Mechanics and Wave Theory.
What is the Alternative to the Quantum Mechanics 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.
Quantum Mechanics for Dummies?
This is the title of a book that teaches how to perform the calculations of Quantum Mechanics, in very simple easy to follow terms.
How does light waves and radioactive decay relate to Quantum Mechanics?
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.
When was Principles of Quantum Mechanics created?
Principles of Quantum Mechanics was created in 1930.
Why it is said relativistic quantum mechanics?
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.
Is newton known for quantum mechanics?
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.
What is a mixed state in quantum mechanics?
The mixed state in quantum mechanics is the statistical ensemble of the pure states.
Who created Quantum Mechanics and is it true that it is replacing the old physics?
Quantum Mechanics "replaced" Classical Mechanics in particle physics in mid-1930s.
Why quantum mechanics is someone called wave mechanics?
It is also called wave mechanics because quantum mechanics governed by Schrodinger's wave equation in it's wave-formulation.
What is the alternative to quantum mechanics?
Classical Mechanics and Wave Theory.
Is quantum mechanics a set of fields or is it just a lone branch of mechanics?
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.
Why plasma is not explained with quantum mechanics?
I am not aware of it "not being explained". I would guess that you can explain the relevant aspects with quantum mechanics.
What was The idea that light can act as packets led to what new field of science?
Quantum mechanics

What is Quantum Mechanics Service?
A joke
