Answer 2

The most basic aspect of quantum mechanics that I have found is that you have to learn to understand that classical mechanics is an approximation of quantum mechanics and not the other way around.

The second basic thing is NOT to get mired into the discussion of wave/particle duality. In reality quantum mechanical systems are neither. You learn nothing about them by trying to interpret them in wave and particle terms.

These two ground rules will stop you from wasting time on trying to understand QM as an extension of classical physics.

Beyond that you will simply have to get a good text book on QM and learn the formalism and its interpretations.

But before you do that I would really suggest you get a VERY THOROUGH introduction to Lagrange and Hamiltonian mechanics. It turns out that the structure of Hamiltonian mechanics is mirrored very closely in QM and you will not understand the quantization rules and crucial details if you can not live and breathe Hamiltonians. Without Lagrange you won't be able to make a successful transition to Path Integrals which underly much of the important numerical aspects of quantum field theory.

A lot of physics classes spend an eternity on Newton, then race through Lagrange and Hamilton in two weeks. This is WRONG. There is nothing mathematically fundamental about Newtonian mechanics but there is EVERYTHING important about both Lagrange and Hamilton. And they both lead to different ways of looking at the same thing. And you will need both if you want to understand what QM is really about.

Answer 3

1. That the state of a particle is fully described by a wave function or state vector, whose norm is the probability of finding the particle at a given point in phase space, and

2. That this wave function evolves according to the Schodinger equation, and

3. That for every possible observable, there exists an operator, such that the possible values obtained from the observation are the eigenvalues of the operator, and

4. That these operators must have commutators equal to ih-bar times the Poisson Bracket of the classical operators in Hamiltonian mechanics.

Answer 4

Basic are: Photoelectric Effect, Heisenberg Uncertainty Principle, Schroedinger Wave Equation, Bose-Einstein Statistics, Superconductivity, Superfliuds, Probability amplitudes and probability distributions, Feynmann Diagrams and all sorts of other stuff that takes too long and too much math to do justice in this forum.

Answer 5

Quantum mechanics as well as String theory is based on Planck's constant. This is where the theories revolve.

Answer 6

quantum or classical physics

physics that we can observe directly with our eyes and or we can feel somehow.
