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.

Can you use quantum mechanics to predict outcome of a football match?
no
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 the mathematics of combining quantum theory with wave motion of atomic particles?
In short, it is called de Broglie wave (or matter wave). Which relates frequency and wavelength to momentum and energy. This relation then leads to group velocity which is an important part of quantum mechanics.
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.
What is the Difference between relativity and quantum mechanics?
Quantum Mechanics is the study of the intimate behavior of the smallest forms of particles, and their interaction amongst, with special emphasys on the emissions of energy, which is delivered in quanta, or photons. Wave Mechanics is the study of many physical phenomena that happen in a non linear and recurrent behavior, usually addressed as wave, with special emphasys in both the features of said wave, and the energy that involves specific wave phenomena.
Can you use quantum mechanics to predict outcome of a football match?

What jobs use complex numbers?
electrical engineers and quantum mechanics use them.
How do quantum mechanics use complex numbers?
using contraction and expansion
Does the current periodic table make use of quantum mechanics model?
No, it is not necessary.
What is the significance of the no communication theorem in the context of quantum mechanics?
The no communication theorem in quantum mechanics states that it is impossible to use quantum systems to communicate faster than the speed of light. This is significant because it sets a fundamental limit on how information can be transmitted in the quantum world, impacting our understanding of the nature of reality and the possibilities of quantum technologies.
How do you use physicist in a sentence?
The physicist conducted groundbreaking research in the field of quantum mechanics.
How does Schneider's cat work?
Schneider's cat works by quantum theory of superposition, and interpretations of quantum mechanics have been proposed. There for showing you the use of Schneider's cat work.
How can we deal with the challenges posed by incompatible observables in quantum mechanics?
One way to address the challenges of incompatible observables in quantum mechanics is to use mathematical tools such as the uncertainty principle to understand and predict the behavior of quantum systems. Additionally, researchers are exploring new theoretical frameworks and experimental techniques to better reconcile these incompatible observables and improve our understanding of quantum phenomena.
What is quantum computer?
Quantum Computers are a new type of computer that uses the principles of quantum mechanics to perform operations. Unlike traditional computers, which use bits to store and process information, Quantum Computers use qubits. Qubits can represent 0 and 1 at the same time, allowing Quantum Computers to perform multiple operations simultaneously.
Why did schrodinger use probability?
Erwin Schrödinger was a physicist and a father of quantum mechanics. Quantum mechanics deals a lot with probability. His famous Schrödinger equation, which deals with how the quantum state of a physical system changes in time, uses probability in how it deals with the local conservation of probability density.
