h-bar (the letter "h" with a horizontal line) is equal to Planck's constant, divided by (2 x pi). Wikipedia says the following about this: "In applications where it is natural to use the angular frequency (i.e. where the frequency is expressed in terms of radians per second instead of rotations per second or Hertz) it is often useful to absorb a factor of 2Ï€ into the Planck constant." In other words, when there is a rotation, or a distance around something (as in an electron's path around the atom), the factor 2 x pi appears quite naturally; so the h-bar is used as a convenient shortcut.

Careers that use quantum mechanics I know this area of physics is more theoretical than anything but are there any?
Some careers that involve the application of quantum mechanics include quantum computing, quantum cryptography, and quantum sensing. These fields explore ways to harness the principles of quantum mechanics for technological advancements in computing, communication, and sensing technologies. Researchers and engineers in these areas work to develop new quantum technologies with potentially transformative impacts on various industries.
What is the mathematics of combining quantum theory with wave motion of atomic particles?
Quantum theory describes the behavior of atomic particles in terms of probability waves. When combining quantum theory with wave motion, we use mathematical tools such as Schrödinger's equation to describe the wave function of a quantum system. This helps us understand phenomena like wave-particle duality and interference patterns in quantum mechanics.
Why you use some classical mechanics in quantum mechanics?
Classical mechanics provides a useful framework for understanding quantum mechanics in limit of large systems. Many quantum concepts, like wave-particle duality and Hamiltonian mechanics, can be connected to their classical counterparts. This allows us to make sense of quantum phenomena by relating them to the familiar concepts of classical physics.
What is the Difference between relativity and quantum mechanics?
Relativity is a theory that describes the behavior of large-scale objects, such as planets and galaxies, in terms of gravity and the curvature of spacetime, as formulated by Albert Einstein. Quantum mechanics, on the other hand, is a theory that describes the behavior of subatomic particles, such as electrons and photons, in terms of probabilities and wave functions. The two theories are successful in their respective domains but have not been reconciled into a single theory of everything.
