An exact? expression for the fine structure constant

In summary, the conversation discusses the relationship between \alpha, the fine-structure constant, and \mu, the first term of the electron's magnetic moment anomaly. By filling in the value of \alpha and using the exact value for pi, a value for \alpha within the measurement range is obtained. However, the significance of this result is uncertain. The poster, Hans, suggests moving the discussion to Nuclei & Particles or TheorDev.

Just for the record:


[tex]\ \alpha^{-\frac{1}{2}}\ +\ \alpha^\frac{1}{2}\ \mu\ =\ e^{\pi^2/4}[/tex]


Where [itex]\alpha[/itex], the fine-structure constant = 1/137.03599911 (46)
and [itex]\mu=1+\frac{\alpha}{2\pi}[/itex] is Schwingers first term of the electrons
magnetic moment anomaly.

Fill in 1/137.03599911 for [itex]\alpha[/itex] and you'll get for pi:

3.14159265263 which only differs in the 10th digit with the real value:
3.14159265358...

Using the exact value for pi results in a value for the fine structure
constant of: 1/137.03599952837 which is within the measurement range.

Does it mean anything? maybe, maybe not.

Regards, Hans

I supposse this is to be moderated out of LQG/strings, but still I am amazed with de Vries' numerologist ability. Perhaps it should be moved to Nuclei & Particles; there is already a copy of the post in TheorDev, and it seems too deep for the TeorDev posters... no answers there.

BTW, the thread in "theory dev" is closed, so at least there is not multiple postings.

Note that previous developments from De Vries (the grand-grand-son of KdV fame?) were related to logarithmic scales and hyperbolic sines. One wonders if it is also the same thing here.
 

Related to An exact? expression for the fine structure constant

1. What is the fine structure constant?

The fine structure constant, denoted by the Greek letter α (alpha), is a dimensionless physical constant that determines the strength of the electromagnetic interaction between elementary particles. It is also known as the coupling constant for the electromagnetic force.

2. Why is the fine structure constant important?

The fine structure constant is important because it is a fundamental constant of nature that appears in many equations and theories in physics, including quantum electrodynamics, the theory of the electromagnetic force. It also helps us understand the behavior of atoms and molecules, and plays a crucial role in the study of the structure of matter.

3. What is the exact expression for the fine structure constant?

The exact expression for the fine structure constant is α = e²/ (4πε₀ħc), where e is the elementary charge, ε₀ is the permittivity of free space, ħ is the reduced Planck's constant, and c is the speed of light in vacuum. This expression relates the fine structure constant to other fundamental constants of nature.

4. How is the fine structure constant measured?

The fine structure constant is measured using various experimental techniques, such as precision atomic spectroscopy and measurements of the electron's magnetic moment. The most accurate value of α is currently determined by comparing the predicted and measured value of the anomalous magnetic moment of the electron.

5. Has the value of the fine structure constant changed over time?

There is no evidence to suggest that the value of the fine structure constant has changed over time. In fact, it is considered to be one of the most stable fundamental constants of nature. However, there have been some controversial studies that suggest a small variation in the value of α, but these have not been widely accepted by the scientific community.
