Quantum mechanics, including quantum field theory, is a fundamental theory in physics which describes nature at the smallest scales of energy levels of atoms and subatomic particles.

hola!
If we look at simple defintion of Quantum mechanics, one will say:-
QUANTUM MECHANICS is the body of scientific laws that describe the behavior of photons, electrons and the other particles that make up the our beloved universe. :D
but,
This definition isn't enough for ones who are truly ddvoted to Physics n' aspire to know each n' everyconcept of Sciences.
So for them, Quantum mechanics is:-
The world of our every-day experiences – the world of the not too big (Umm... compared to our galaxy), and the not too small, (compared to mass of an atom), and where nothing moves too fast (compared to the speed of light) – is the world that is mostly directly accessible to our senses.
This is the world usually more than adequately described by the theories of classical physics that dominated the nineteenth century:-
→ Newton’s laws of motion,
→ Newton's law of gravitation
→ Maxwell’s equations for the electromagnetic field
→ Three laws of thermodynamics.
Quantum mechanics is often thought of as being the physics of the very small as seen through its successes in describing the structure and properties of atoms and molecules – the chemical properties of matter – the structure of atomic nuclei and the properties of elementary particles.
But this is true only insofar as the fact that peculiarly quantum effects are most readily observed at the atomic level.
In the everyday world that we usually experience, where the classical laws of Newton and Maxwell seem to be able to explain so much, it quickly becomes apparent that classical theory is unable to explain many things.
for example:-
♦ why a solid is ‘solid’
♦ why a hot object has the colour? etc.
Quantum Mechanics helps us discover answers to many question which are unknown to us
The overall approach Quantum Mechanics adopted here is one of inductive reasoning, that is the subject is developed by a process of trying to see what might work, or what meaning might be given to a certain mathematical or physical result or observation, and then testing the proposal against the scientific evidence.
The procedure is not a totally logical one, but the result is a logical edifice that is only logical after the fact, is that the justification of what is proposed is based purely on its ability to agree with what is known about the physical world.
