Strictly speaking, precisely nothing. However, there is a dimensionless constant that happens to have a value close to 1/137 (but not exactly). For some years it was thought that it was exactly 1/137, and the myth has stuck.

The number 137 is known as the fine-structure constant, a dimensionless physical constant that plays a key role in quantum mechanics. It describes the strength of electromagnetic interactions between elementary charged particles and is fundamental to explaining the behavior of atoms and light. The significance of 137 lies in its mysterious appearance in various physical equations and its influence on the structure of matter at the quantum level.

What are vibrational and rotational quantum number?
Vibrational quantum number indicates the vibrational energy level of a molecule, while rotational quantum number describes the rotational energy level. Both quantum numbers are used to describe the quantized energy states of a molecule in quantum mechanics.
How many people have a job in quantum mechanics in the US?
There is a small but growing number of people working in the field of quantum mechanics in the US, with estimates suggesting that there may be several thousand researchers and professionals engaged in this area. However, an exact number is challenging to determine due to the diverse range of industries and research institutions involved in quantum mechanics.
What is a mixed state in quantum mechanics?
The mixed state in quantum mechanics is the statistical ensemble of the pure states.
What is the alternative to quantum mechanics?
Classical mechanics is the alternative to quantum mechanics. It is a branch of physics that describes the motion of macroscopic objects using principles established by Isaac Newton. Unlike quantum mechanics, classical mechanics assumes that objects have definite positions and velocities at all times.
What do people say about future research concerning quantum mechanics?
People often discuss future research in quantum mechanics as focusing on developing practical quantum technologies like quantum computing, communication, and sensing. Some also highlight the need to better understand fundamental aspects of quantum mechanics, such as the nature of entanglement and the interpretation of quantum phenomena. Additionally, there is growing interest in exploring the implications of quantum mechanics for fields like artificial intelligence, materials science, and cryptography.
When was Principles of Quantum Mechanics created?
Principles of Quantum Mechanics was created in 1930.
Why it is said relativistic quantum mechanics?
The distinction is sometimes made to distinguish normal quantum mechanics (which does not incorporate special relativity) and quantum field theory (relativistic quantum mechanics). Since we know special relativity is correct it is the relativistic form of quantum mechanics which is true, but non-relativistic quantum mechanics is still used, because it is a good approximation at low energies and it is much simpler. Physics students typically study regular quantum mechanics before moving on to quantum field theory.
What are vibrational and rotational quantum number?
Vibrational quantum number indicates the vibrational energy level of a molecule, while rotational quantum number describes the rotational energy level. Both quantum numbers are used to describe the quantized energy states of a molecule in quantum mechanics.

Is newton known for quantum mechanics?
The concepts of quantum mechanics were not explored until the 20th century. Newton only lived into the 18th century, so Newton did no work on quantum mechanics.
Who created Quantum Mechanics and is it true that it is replacing the old physics?
Quantum Mechanics "replaced" Classical Mechanics in particle physics in mid-1930s.
What is a mixed state in quantum mechanics?
The mixed state in quantum mechanics is the statistical ensemble of the pure states.
What is the difference between quantum mechanics and quantum physics?
Quantum mechanics is a branch of physics that deals with the mathematical description of the behavior of particles on the atomic and subatomic scale. Quantum physics is the broader field that encompasses quantum mechanics along with other related topics, such as quantum field theory. In essence, quantum mechanics is a subset of quantum physics.
Why quantum mechanics is someone called wave mechanics?
It is also called wave mechanics because quantum mechanics governed by Schrodinger's wave equation in it's wave-formulation.
Is quantum mechanics a set of fields or is it just a lone branch of mechanics?
Quantum mechanics is a separate branch of physics. It is a general term given to all quantum physics. There are many subbranches, for example Quantum chronodynamics which describes the strong nuclear interaction.
What is the alternative to quantum mechanics?
Classical mechanics is the alternative to quantum mechanics. It is a branch of physics that describes the motion of macroscopic objects using principles established by Isaac Newton. Unlike quantum mechanics, classical mechanics assumes that objects have definite positions and velocities at all times.
Why plasma is not explained with quantum mechanics?
I am not aware of it "not being explained". I would guess that you can explain the relevant aspects with quantum mechanics.
