Why you use some classical mechanics in quantum mechanics?
That has been a topic of much debate since th1900's. There has been no fully successful tying of the two branches of physics yet but, many proposed theories have made great leaps forward to the answer. For example quantum gravity theory and the string theory, the latter being the more current and relevant.There are two areas in which the transition from quantum mechanics to classical mechanics is rather obvious: Statistical thermodynamics and wave-particle duality.Answer2:Classical and Quantum Mechanics merge in Quaternion Mechanics.Quaternion Mechanics consists of Quaternion quantities like energyW = -vh/r + cP where -vh/r is the scalar enrgy and cP=cmV is the vector energy.Classical and Quantum Mechanics need Quaternion quantities. In general the potential energy -vh/r is a scalar aka a Boson and vector energy cP is a vector aka a Fermion. Bosons/Scalars have integer spin and Fermions/Vectors have 1/2 integer spin.For the most part like Newtonian Physics use only scalars -mGM/r a scalar and no vectors. Likewise, Quantum mechanics use mostly Fermions or Vectors and few scalars. The speed of light is a scalar as is Planck's Constant h.Quaternion Mechanics merges Classical and Quantum Physics.The Laws of Quaternion Mechanics are:0 = XB = [d/dr, DEL] [B,B] = [dB/dr -DEL.B, dB/dr + DEL B ]0 = X2B = [(d2/dr2 - DEL2), 2d/dr DEL] [-vh/r,cP]This Quaternion Wave gives thescalar/Boson wave -(d2/dr2 - DEL2)vh/r - 2d/dr DEL.cP =0and thevector/Fermion particle (d2/dr2 - DEL2)cP + 2d/dr DEL -vh/r =0In Nature, Quaternions rule and Quaternions combine Bosons and Fermions.A Quaternion can be a Boson or a Fermion or Both as inX2W =[ -(d2/dr2 - DEL2)vh/r - 2d/dr DEL.cP,(d2/dr2 - DEL2)cP + 2d/dr( DEL -vh/r + DELxcP) ]Quaternions consist of Scalars and Vectors , Bosons and Fermions.
Careers that use quantum mechanics I know this area of physics is more theoretical than anything but are there any?
The obvious choice would be a research or academic physicist. These are professions that are primarily in the public sector meaning that you would be employed by a university or the government. As for industry, there are still some companies that employ quantum physicists but they are usually R and D departments of large technology companies. Not a lot of businesses directly employ quantum mechanics directly, but there are a lot that use the results of experiments to develop new, and improve old, technologies. Possible areas for research include superconductivity, quantum computing, particle physics and string theory. Maybe chemistry too.
What is spin quantum number?
Good question! Experiments show that the electron "behaves" as if it is a spinning ball of charge. But be careful...the electron IS NOT a spinning ball of charge. Instead the concept is quantum mechanical and has no actual classical analogy. why we r taking the spin of the electorn is +1/2 or -1/2 is there any relation bet rotational symmetry
What is an operator in quantum mechanics?
In the dirac view of quantum mechanics, operators are the center of analysis. An operator is some mathematical operation that acts on the wavefunction (psi) which returns an observable. Lets look at some examples: say psi=exp(ik(dot)r)*exp(iomega*t) (which is the case for a free particle) the momentum operator is the -ihbar gradiant applying this to our psi- we get hbar k. This is called the observable. perhaps more familiar the energy operator which would likewise return hbar omega. Now doesn't that look familiar! Interestingly enough, these two examples point out that the conservation of momentum and energy stem from the laws of physics being invariant, regardless of position and time.
