== Another physical aspect ==

The [[Schwinger effect]]: there can't be isolated point-like charged particles of more than 1/α (about 137) unit charges because an electric field that strong leads to pair creation of which one particle gets bound in the lowest possible energy state the other one escapes. 

This can theoretically occur when shooting heavy nuclei at each other, creating temporary ultra-heavy cores (however, as nuclei aren't point-like but have a volume, it requires about 170 protons for the effect to occur)  <span style="font-size: smaller;" class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/91.15.69.115|91.15.69.115]] ([[User talk:91.15.69.115|talk]]) 19:14, 9 March 2012 (UTC)</span><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->

This is not only unclear, but in my opinion also thoroughly nonnotable. People have tried zillions of calculations to "explain" the numerical value of the fine-structure constant, and non-surprisingly some came out somewhere near 137 or its inverse. The result referred to does not stand out in any way among this fringe. No plausible connection grounded in any physics theory is offered for a connection between the dynamic system considered and electromagnetic interaction.

== Eddington's Wish... ==

1/137 is actually quite a special number- expressed in decimal notation it shows palindromic repeats, and in fact the largest length palindromic repeats (6 units) for at least 50,000 whole integer denominators, when both numerator and denominator are whole integers. Thus it is very curious that the FSC is so close to it. Also makes one wonder whether deviation FROM this fraction has other causes, which distort what it *should* be ideally.  <span style="font-size: smaller;" class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/69.121.117.192|69.121.117.192]] ([[User talk:69.121.117.192|talk]]) 13:35, 7 June 2012 (UTC)</span><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->

== The Fine Structure Constant is likely governed by Primitive Pythagorean Triples that form n^2 Multiples by: Brian Nelson ==
Integer based derivations of Einstein's relativistic mass-energy equation and deBroglie's wave equation suggest the Compton and deBroglie wavelengths are governed by a Pythagorean triple whose multiples provide orbital stability by maximizing the overlap between the interlaced waves. A systematic search across the uncertainty range of the Fine Structure Constant reciprocal (137.035999084(51)) results in a single primitive Pythagorean Triple that forms 9X the number of  n^2 multiples above any other primitive triple suggesting it is the exact value of this constant:

== FSC as a mass ratio ==

The ratio of the anti-matter pair electron-positron to the charged pi-meson mass produces a number which is not terribly far off from the fine structure constant: 2m_e/pi^+- = 0.00732247. The electron mass is well determined precisely and accurately by 2010 Codata (it is very good) from the NIST while the charged pion mass determination is from the Particle Data Group (PDG). If the PDG value is not as good as it should be maybe a future determination will bring it in line with the FSC.  <span style="font-size: smaller;" class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/167.29.4.150|167.29.4.150]] ([[User talk:167.29.4.150|talk]]) 18:17, 12 January 2013 (UTC)</span><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->

== Anthropic explanation ==

Checking the article (http://dx.doi.org/10.1111%2Fj.1749-6632.2001.tb02133.x), I see :

"If, instead, we consider the allowed variations in the strength of the strong nuclear force, αs, and α then roughly αs < 0.3α^1/2 is required for the stability of biologically useful elements like carbon. If we increase αs by 4 percent, there is disaster because the helium-2 isotope can exist (it just fails to be bound by about 70 KeV in practice) and allows very fast direct proton + proton → helium-2 fusion. Stars would rapidly exhaust their fuel and collapse to degenerate states or black holes. In contrast, if αs were decreased by about 10 percent, then the deuterium nucleus would cease to be bound, and the nuclear astrophysical pathways to the build up of biological elements would be blocked." 

in the text I think there is a confusion between alpha and alpha_s.  <span style="font-size: smaller;" class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/147.156.174.225|147.156.174.225]] ([[User talk:147.156.174.225|talk]]) 17:48, 22 July 2013 (UTC)</span><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->

== <!--e-Nut or -->Shape of Spinning Electron: how to extract Fine Structure Constant from Proton-to-Electron Mass Ratio ==
[[Image:Polygon formed by spinning electron.svg|frame|right|Geometrical model of spinning electron: </br>'''n'''-sided polygon with rounded corners.</br>Unit of length corresponds to diameter of proton.]]
Article describes a contour of spinning electron and derives a value of the Fine Structure constant from Proton-to-Electron mass ratio on basis of the facts that both electron and proton have equal spin angular momentum while proton is heavier than electron more than 1836 times.
</br>
It appears from suggested model that the path of rotating electron is shaped as hardware nut (regular polygon) with 137 sides and rounded corners.<!-- This figure may be potentially called e-Nut with letter e standing for an electron.-->
</br>
Numerical outcome of the model: electron’s spin circumference is 137.035999118… times longer than diameter of spinning proton. It is proven that this ratio is physically the Fine Structure constant. The result is located right on the upper boundary of the CODATA Fine Structure constant reciprocal recommended value range.
</br>
Key formula for the number of sides '''n''' in polygon formed by electron’s spinning body:
::::::::<math>n = round up to prime {(\pi \cdot {\sqrt{\frac{m_p}{m_e}}})} = 137</math>

==Theory of fine-structure constant was published already==

I would like to note that the use of the term "Numerology" in this article does not correspond to its definition given in the Wikipedia itself.  Such a common contradiction (to a lesser extent in the identical German and Russian articles) creates a negative attitude for the fine structure constant in this article. At the same time the "Coupling constant" article gives only neutral information about the fine structure constant (as well as other constants). I may say about each paragraph in «Numerological explanations» the same what Lambian said in «Unclear paragraph on non-notable result».  
Eventually this article must be combined with the "Coupling constant" article because at least first three of them are: α^(0*0), α^(1*1), α^(2*2) (next are α^(3*3), α^(4*4), α^(5*5), ... but accuracy of calculations must be as twice as more than 64 bits).[[User:Алры|Алры]] ([[User talk:Алры|talk]]) 16:30, 24 February 2014 (UTC)

I'm aware of a physical representation of <math>\alpha</math> derived from purely classical means.

To see this, note that <math>\omega = {1 \over \sqrt{LC}} = {1 \over \sqrt{\alpha a_0 \mu_0 \alpha a_0 \epsilon_0}}</math>  = 7.7634408 x 10E20 rad/s. This frequency corresponds to a photon of energy 510998.896 eV, which is also <math>m_0</math>. Has this ever been described? The implication to particle  production is evident. This describes a necessary condition for a photon with energy of the electron rest mass to experience infinite vacuum impedance.

==  Electromagnetic coupling constant g ==

In the article it says ''It is related to the electromagnetic coupling constant g'' whereas following the link it is then only called ''gauge coupling parameter, g''. In the German article the "fine-structure constant" is equivalent to and just another name for the "electromagnetic coupling constant". I guess it is a mistake in this article. [[User:Ra-raisch|Ra-raisch]] ([[User talk:Ra-raisch|talk]]) 19:22, 21 May 2015 (UTC)

:AFAIK, the term "electromagnetic coupling constant" is often used for ''α'', but this is unfortunately a misnomer. My memory may be failing me, but I think that Feynman used the term to refer to ''e'', the elementary charge.  The latter use is in keeping with the use of the term "coupling constant".  The use of ''g'' as a symbol is probably just a way of changing the units of ''e''. The lead is definitely not satisfactory in this regard at the moment.  I'd like to see us not using the term "electromagnetic coupling constant" for ''α'' (because it is a bad use), but rather just mention that this is often what it is used to mean, preferably not even in the lead. ''α'' is proportional to the square of what I'm here calling Feynman's electromagnetic coupling constant.  —[[User_talk:Quondum|Quondum]] 23:46, 21 May 2015 (UTC)

== Removed the 1/128 reference: here's why ==

There was previously a reference to a sheet of physical constants, provided by NIST. It included a reference to a high value of alpha at high energies, and this was mentioned in the article (~1/128).
<br>
Although this is not made clear in the NIST reference, this "alpha" is not the same as the fine-structure constant referred to in this article, which really is a constant that relates precisely to other physical constants in a known and simple way. 
<br>
The alpha mentioned in the NIST reference is alpha_sub_2 = alpha /(sin theta_w), which is a variable.
<br>
Check out A Modern Introduction to Particle Physics by  By Fayyazuddin, Riazuddin for more details.
<br>
In any case, including this reference will mislead the reader. Under all circumstances, the fine-structure constant is fixed, as defined at the start of this article.

== Relativistic mass ratios of neutron, proton, and electron give exact value for fine structure constant ==

The following equation, proposed by Michael John Sarnowski, in "Relativistic Equation for the Fine-Structure Constant Using the Polynested Spinning Spheres Theory of the Cuboctahedron"[http://vixra.org/pdf/1507.0128v1.pdf] for the fine structure constant.  

Equation 2.1	fine structure constant= ::<math>\sigma=\frac{1}{\sqrt {1-(\frac{\pi Me}{3*3Mn}})^2}T\pi^3 \frac {Me}{4Mn}</math>

Where ::<math>T^2</math> is proposed to be as follows

Equation 2.2
	::<math>T^2=(\frac {Mp-Me}{Mn})^2+
(\frac{Mn}{Mn})^2+(\frac{Mn}{Mn})^2</math>

Where  Me=Mass of the Electron, Mp=Mass of Proton, and Mn=Mass of Neutron, and T is defined above.

From equation 2.1 and using the 2014 Codata values we obtain 
::<math>\sigma^{-1}=137.035999146</math> which compares to the 2014 inverse fine structure constant of ::<math>\sigma^{-1}=137.035999139(31)</math>.  These values are well within one sigma of each other.[http://physics.nist.gov/cgi-bin/cuu/Value?alphinv][http://vixra.org/pdf/1507.0128v1.pdf]

Using the values of Mp/Mn=0.99862347872 and Me/Mn=0.00054386734442 obtained from (3),(4)
we obtain <math>\sigma^{-1}=137.035999098</math> (5)

==Spatial Variation Of Fine Structure Constant==

The group working with J. K. Webb published results showing a dipole spatial variation in the fine structure constant with axis that appeared to be passing through the South Magnetic Pole of Earth. Discussions following publication of the first arixv article suggested some interaction of the magnetic field with the optical measurements. General relativity allows such an interaction to occur through the electromagnetic stress energy tensor, but most strongly for magnetic monopoles which have not been found. Magnetic dipole field of Earth has a long base line which allows the two poles to act independently in regions of considerations for General Relativity around the two telescopes. Gravity of Earth can also interact with optics through stress energy. Doctor Webb indicated in other correspondence his knowledge on these possibilities and others not discussed in the arxiv articles due to space limitations.

This article discusses concerns about accuracy of the measurements and possible differences in the two telescopes, but fails to notice whether or not the apparent spatial variation occurred in both telescopes equally when they observed the same object. "A search for systematics, using observations duplicated at both telescopes, reveals none so far which emulate this result."<ref>{{Cite journal|arxiv=1008.3907|last1=Webb|first1=J. K|title=Indications of a spatial variation of the fine structure constant|journal=Physical Review Letters|volume=107|issue=19|last2=King|first2=J. A|last3=Murphy|first3=M. T|last4=Flambaum|first4=V. V|last5=Carswell|first5=R. F|last6=Bainbridge|first6=M. B|year=2010|doi=10.1103/PhysRevLett.107.191101}}</ref> Also the possibility of a stress energy interaction is not reflected in the article. 

A major issue is involved in that the published data from Australia is suggesting a preferred location and axial direction in space, in disagreement with modern astronomy and physics. If true it will require confirming data from other researchers and a serious discussion among specialists in the field. Additional published data in arxiv from the Australian group seems to support the original findings. Something important might have been discovered, but the explanation of it is not satisfactory. The article needs help from technical experts. [[User:Astrojed|Astrojed]] ([[User talk:Astrojed|talk]]) 22:54, 14 October 2015 (UTC)

Further work removed much concern about differences between the two telescopes. "Independent VLT and Keck samples give consistent dipole directions and amplitudes ..."

Just asking if the sentence

should read 

"... the '''maximum''' angular momentum allowed by relativity..." (...and the minimum by QM)?
--[[User:J. Sketter|J. Sketter]] ([[User talk:J. Sketter|talk]]) 03:57, 5 February 2018 (UTC)

:No, absolutely not. It is not important, but the throwaway sentence invites you to visualize circular orbits of a classical electron, before quantization constraints. In that case, the angular momentum goes as <math>\sqrt r </math> and, equivalently, as <math>e^2/v</math>.  As the radius of the orbit ''decreases'', the velocity ''increases''.  The classical angular momentum, then, naively, is ''decreasing with v'', and achieves its ''minimum'' at <math>e^2/c</math>. Comparing, then,  with the likewise minimum angular momentum provided by the quantization condition  yields ''α''. It's a formal wisecrack---if it doesn't speak to you, you might pass it over.

== Finally an actual explanation for alpha that's based in mathematics and is in a published peer-reviewed journal ==

International Journal of Quantum Foundations 3(2017) 100 - 118, a copy of which may be obtained here, https://www.researchgate.net/publication/320110017_Quantum_Jumps_and_Electrodynamical_Description - section 4.

the original formula - for which there was no explanation provided because it was found by a ''programmer'' with deep analytical and pattern-recognition skills - is here: http://www.chip-architect.com/news/2004_10_04_The_Electro_Magnetic_coupling_constant.html

unlike many other reverse-engineered formula for alpha the de vries formula has an extremely low [[Kolmogorov Complexity]] in its recursive expression, and its maclaurin-like series form extremely similar to the well-known electron g/2 formula.  <!-- Template:Unsigned --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Lkcl|Lkcl]] ([[User talk:Lkcl#top|talk]] • [[Special:Contributions/Lkcl|contribs]]) 15:47, 4 July 2018 (UTC)</small> <!--Autosigned by SineBot-->

it has been noted that the de vries formula, due to it being recursive and also requiring to be implemented using subtraction of extremely small reciprocal differences, requires ''extraordinary'' levels of floating-point precision to get the right value: several people have been caught out by using spreadsheets or in one case FORTRAN using only IEEE754 32-bit floats.  the most accurate implementation to date uses a python arbitrary precision library (bigfloat) that sets 150 digits. http://lkcl.net/reports/fine_structure_constant/alpha.py

the explanation by leonardo chianti, is based on the theory that time is a complex number (i think), and that time-dilation effects are involved in the generation of "virtual photons" as the electron's energy goes round in an infinite loop.  that loops of virtual photons are created and destroyed, going not only along the circumference of the electron radius but also '''across''' the circumference, hence the ratio (to a first iterative approximation) involving 1 + alpha/2pi.  however the second iteration of time-dilation interacts with the first, hence the additional multiplication by another factor 1 + alpha/2pi, and the third, and the fourth and so on to infinity, creating the iterative series.

this is quite literally the first explanation for alpha that has ever been proposed which actually has a fundamental theoretical basis... and is dead-accurate.  all other theories that have ever been proposed over the past 100 years either are inaccurate (contain some approximation of some kind) or the theory behind them has no real rational scientifically sound basis.<!-- Template:Unsigned --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Lkcl|Lkcl]] ([[User talk:Lkcl#top|talk]] • [[Special:Contributions/Lkcl|contribs]]) 15:47, 4 July 2018 (UTC)</small> <!--Autosigned by SineBot-->

update: a recent new measurement of alpha was made (2020?) which is something mad like 11 decimal places.  the de vries value for alpha is *still accurate* within the measured experimental uncertainty. all other formulae (including those from notable physicists) have magic constants or are simply not accurate. this "unexplained" formula discovered by a programmer is still the only formula that remains accurate [[User:Lkcl|Lkcl]] ([[User talk:Lkcl|talk]]) 23:58, 8 August 2021 (UTC)

I want to point out that the few references to a theory involving "quantum micro black holes" seem to be just one other among many attempts to explain the fine structure constant - this seems to me not suitable for such a general Wikipedia article.

The creditable source listed is just a huge repository of documents.  None of the sources cited have been peer reviewed.  In some of Lestone's work, they specifically say they're looking for a way to make alpha be just another universal constant like e or pi.

This whole thing is equivalent to me claiming to have proven aliens exist, and most people think I'm crazy for believing it, but this other paper shows we definitely can't rule it out, therefore my idea is reasonable.

== "subatomic particles and {{math|''α''}}" in "physical interpretations" ==
Previous version deleted by ESnyder2 „numerological, non-scientific explanation”.  [[Yoichiro Nambu]] of the 1st ref got the nobel for physics in 2008, so I'd rather classify at least his work as „science“. Numerology - sure there is a lot, on a level with e.g. the [[Koide formula]]. However, the cited relation for α is based on a model conventionally derived from a DE.

: I believe you badly misunderstood Nambu's paper: He definitely did ''not'' derive 1/α in that paper: he ''utilized'' it to propose regularities of masses of elementary particles using it as a yardstick, regularities invalidated by posterity. That was 67 years ago, and, since, much more has been learned about elementary particles to invalidate this speculation.  You cannot implicate α in failed attempts at progress. Koide would be first to object to his intriguing formula being used as an excuse for including obsolete pablum in a general article of this kind. Sure, α underlies the Balmer series, as  already discussed in the article. Using it as an excuse to insert pseudoscience in a mainstream article, however, is rich.

It is fairly clear from the article and talk that there is a commonly held view that the fine structure constant is not a constant, but that it runs with energy. In preparation for future new science, I propose the remaing of the page to "Fine-structure value". It can be made clear that the value is as determined by experiments under certain conditions corresponding to test results at relatively low energy. An alternate proposal would be the "Fine-structure asymptote" which would be the low energy asymptote of the fine structure variable. To continue to call this a constant, when there is widespread scientific evidence that the fine structure "runs with energy" is wrong.

== Why 1/137 versus 137 ==

It would be good if this article were to explain why this constant was defined as being less than 1, and not 137.  For example, it could have been decided that π was the ratio of diameter to circumference, and everyone would be forced to use 0.318309886... everywhere.  And of course, there is no reason why this convention could not be changed.  Like how there has been a push to replace pi with tau.  But the article would be improved if it were to present the explanation behind why this more obscure version of the constant was adopted.  Physicists get a warm fuzzy feeling when the h-bar gets put in the denominator.  But there is no rule that says you have to do that.  -- [[User:Tdadamemd19|Tdadamemd19]] ([[User talk:Tdadamemd19|talk]]) 06:08, 30 April 2019 (UTC)

== Formula from units giving a hint for physical deduction ==
The article and discussions of it are very interesting for scientist's comunity.Everybody understands that symple formula births effective theory. I would like to add in part 8 following result of paper<br><ref>{{cite journal |last1=Sergei P. Efimov |title=Symmetries of Fine-Structure Constant |journal=Adv. Studies Theor. Phys. |date=2013 |volume=7 |issue=13 |pages=635-646 |doi=10.12988/astp.2013.3431 |url=http://dx.doi.org/10.12988/astp.2013.3431}}</ref>
The reversed constant is approximately equal to the value:
:''α''<sup>-1</sup> ≈ ('''0.1''')×('''1.11''')×('''11.111''')×('''111.1111''').
That gives nealy 7 valid digits and reminds "message from the Universe". The actual reason of symmetry is to contain hidden symmetry. The quantities of units in multipliers are 1, 3, 5, 7 succesevily. Formula actually contains geometric progressions with common ratio 10 to be equal 1+2+3+4. But correction item may to be "in a bad condition". Nevertheless correction item is equal to ''exp'' (-8+1/32) what gives precise value
:''α''<sup>-1</sup> = ('''0.1''')×('''1.11''')×('''11.111''')×('''111.1111''') + ''exp''  ('''-8+1/32''') = 137.035999074.
What is a wonder now that the value from units stands in the argument of exponent as well. We may see that if to go to 2-coding system from our 10-coding. The quantity of units are equal to 8:
:''exp'' (-8+1/32) → ''exp'' (-'''111.11111''').
Result is very impressive for students but for physics more important to see that progresions arise for Gibbs distribution. Probality of level with energy proportional to (''m'') for according temperature is proportional to 10<sup>-m</sup>. Sum of probabilities of a level with ''m''=0,±1,±2,±3 gives value '''1111.111''' and so on. Therefore, 3D oscillator (levels 2,3 ) and 4-th level of Coulomb problem (''n''=4) give according quantum numbers.

::: the first give-away is that the formula is not accurate to current observed measurements.  the latest measurement (2020) is 11 decimal places, where this one is only seven. the "correction" added, which has no explanation, blows all credibility out the water.
::: a more statistical approach based on Kolmogorov Complexity can be taken, by assigning a probability weighting to each symbol or digit used without explanation in a formula.  when multiplied together these types of formulae VERY rapidly approach zero likelihood.

=== "numerology" extremely offensive, judgemental, and unscientific ===

unfortunately, the entire use of the term "numerology" is invariably itself extremely disparaging and offensive. that people consider themselves eminent scientists yet use such terms in an offensive and disrespectful way is a disgrace and an embarrassment to scientific endeavour.

now to explain that.

i am a reverse-engineer, who was successful enough where others have not been such that i actually made a study of reverse-engineering itself.  i learned of the terms "auto-didact", zero-prior-knowledge derivation, epistemology and many others. part of the success of what i do comes from NOT making prejudiced assumptions and judgements, instead using overwhelming amounts of data and applying judgement-free statistical filtering.

when i encountered alpha and the sheer quantity of attempts to explain it, i did NOT dismiss them as "numerological bullshit", instead i created an analysis system based on Kolmogorov Complexity to analyse their plausability, instead. it turns out that every single one of the formulae failed that test (with one exception: the de vries formula) but the point is that i did NOT dismiss peoples' efforts out of hand.

this is the bit that really pisses me off about people who call themselves "scientists" is that rather than actually use an actual scientific method such as statistical analysis to guage whether these formulae have merit or not, they chose instead to be deeply offensive and judgemental.

the actual section itself on numerological explanations is very well written. it has some encouraging quotes in it.  i am writing this however as a warning to people who use the word "numerology" dismissively. there are much better ways to demonstrate to people that their approach is invalid than to be disparaging and dismissive.

:Many of the efforts of Arthur Eddington have been labelled "numerological" for decades now (see [[Eddington number]]).  And if an attempted "explanation" for a dimensionless physical constant involves no physical parameters or relationship to any physical theory, but instead is derived from pure mathematics only, then it's actually not an "explanation", and might as well be numerology as far as many physicists are concerned.

::
:: yes, it's rather unfortunate.  on the one hand: the reason why i cannot be arrogantly dismissive of things that "fit but have no explanation" is because i trained as a Software Engineer, Security Researcher and in black-box reverse-engineering.  that is a field where you have quite literally no information about anything - at all (worse, if you sign Corporate NDAs to get at the information, those NDAs actively prevent and prohibit you from publishing your results).  consequently, from that training, you learn very quickly that being prejudicially judgemental "because there's no explanation" will, fundamentally, make you absolutely s**t at your job.  it's called zero-knowledge derivation.  think of it this way: if a child learned language without assistance, and the adults told them "no, you're wrong, you can't possibly have learned that word because nobody provided you with the grammar and syntax THEORY to understand it", how would that child react? or: an archaeologist, reconstructing a dead language, purely from context and comparison. is there anybody around to give them the THEORY behind the symbols that look like "meaningless numerology"?
::
:: and yet, on the other hand, deep breath: in the search that i've made of "alternative" theories, holy cow is there a lot of noise-to-signal. i mean, i am totally supportive of the existence of vixra, in that it actually allows people to self-publish, at all. i will always be eternally grateful for that.  however it doesn't mean that it's actual quality work. that means that even *attempting* to find rational and high quality research on vixra and other self-published sites, *including* those which restrict (and censor) their forum discussion to "accepted" science, is extremely challenging.  thus, i am really not surprised that Academics simply disregard anything that is not peer-reviewed.  despite that now being less and less meaningful.
::
:: so it's a difficult situation.  to me, as a reverse-engineer, the de vries formula is a neon flashing sign with the brightness of a supernova.  after several years i've finally made some progress with it, recently, by expressing it in [[Euler's_continued_fraction_formula]] form :<math>r_j = \alpha / (2\pi)^n</math> then substituted "t = cos (theta alpha / 2pi)" into the Rodrigues variant of [[Legendre_polynomials#Rodrigues'_formula_and_other_explicit_formulas]], and am currently working it through to [[Spherical_harmonics]] which is giving me headaches.  the Triangular Number part of de Vries comes from the Rodrigues differentiation.  Early signs are that the infinite series entirely cancels out - with parts of how Spherical Harmonics are expressed (powers of radius to the power of l), leaving just the exp(pi^2/2) part of the de Vries formula, which i've not yet matched up with anything.  it *might* match up with the tensors moment orthogonality weight, but to be honest tensors are completely beyond me at the moment (pun intended).
::
:: i have to say: i should not be the one doing this. i have A-Level mathematics ability, from 1987, for goodness sake.  some physicist, mathematician or basically *anybody* other than me should have picked this up over fifteen years ago and analysed it properly. i'm really quite angry and disappointed with Academia for being so prejudice and closed-minded. and i've spoken over the years to quite a lot of prejudiced Academics, many of them quite prominent.

'...I cannot be arrogantly dismissive of things that "fit but have no explanation"...'

Lckl, a *ton* of things "have no explanation." You seem focused on alpha, but have you attempted this sort of approach for all the other physical constants that also "have no explanation"? The values of the gravitational constant, the Avogadro constant, the speed of light, the Planck constant, the Boltzmann constant, the constants in the lepton mixing matrix, the distance from the Sun to Earth, the maximum wavelength sensitivity in the three types of cone cells, the triple point of water... I could go on, but the point is that these values can be and have been *measured*, just as the fine-structure constant has. None of them have an explanation or a reason for their values. The fact that alpha is dimensionless does not somehow make it more likely to have an explanation than the others. (We could ask, for instance, about the "reason" that the (dimensionless) Reynolds number has a range where liquids change from laminar to turbulent flow.)

To misquote Neil DeGrasse Tyson: The universe is under no obligation to give you reasons for the numbers it is governed by. You can measure the numbers, but they don't need a reason. [[User:ESnyder2|ES2]] ([[User talk:ESnyder2|talk]]) 05:49, 14 October 2021 (UTC)

== Yet another beauty in '''α''' ==
An equality can be written retroactively for the ratio '''π/137''' being expressed as a function (Taylor series) of the fine-structure constant '''α'''.

::::::<math>{{(\pi \cdot \alpha)}^2} + (\pi \cdot \alpha)^4 + \frac{1}{8} \cdot (\pi \cdot \alpha)^6 + ...  =  (\frac{\pi}{137})^2</math>

The result has a very narrow range of values
<math> \alpha^{-1}</math> = 137.0359991676 ± 0.0000000007 satisfying the above equality.

The direct expression for the fine-structure constant '''α''' as a function of the '''π/137''' ratio produces the same result.
::::::<math>(\pi \cdot \alpha)^2 = (\frac{\pi}{137})^2 - (\frac{\pi}{137})^4 + \frac{15}{8} \cdot (\frac{\pi}{137})^6 - \frac{35}{8} \cdot (\frac{\pi}{137})^8 + ...</math>
Also, there is a converging set.
::::::<math>(\pi \cdot \alpha)^2 = \frac{\pi^2}{137^2+\pi^2} \cdot (1 + \frac{7}{8} \cdot (\frac{\pi^2}{137^2+\pi^2})^2 + ...)</math>

== Magnetism ==

Through the last years, starting up to 2016, I have worked on other theories, that Coulombs Law best describes the three known forces as strong and weak atomic/nuclear forces and 'electro-magnetic' radiation quite differently. But the work of Feynman is not part of this. The reach of electrostatic force in these collections, is not much further than the radius of any atom. The electrons in these ideas do not orbit or spin. Magnetism is sought explained as gravity with graviton flux. But light as photons. Link to my homepage in Danish, if these theories have interest, but it has not been translated. www.alternativfysik.dk

This might mean, that at the distance 100.000.000 (10^8) meters, electrostatics differences can be measured, which if I have any clue, what I am saying, means, magnetism on Earth, experimentally almost can be registered on the moon? "Magnetism reaches much further that electrostatic fields. And gravity much, much further that any magnetism, that can be both natural and generated." (384.405 km - 3474*0,5 km - 3474*4*0,5 km =  360.087 km)

The reason the low energy fine structure constant gets determined in a pre-quantum, pre-spacetime theory is the following:

How taking the square-root of Minkowski space-time paves the way for unification:

It is like going from the surface of the ocean to the ocean bed. The ocean floor can exist without the surface, but the surface cannot exist without the floor.

We live in a 4D Minkowski space-time curved by gravitation, in which standard model gauge fields and fermions reside.

But there is a more precise description. We take the square-root of Minkowski space-time and arrive at Penrose's twistor space, described by complex numbers.

In this spinor space-time replace complex numbers by quaternions, then by octonions. More precisely complex bioctonions. We arrive at a space with E_8 x E_8 symmetry whose geometry is a unified description of the standard model and pre-gravitation. The gauge group is

SU(3)_c X SU(2)_L X U(1)_Y x SU(3)_grav X SU(2)_R X U(1)_g

Coupling constants are determined by the geometry.

In the classical limit, the 4D curved spacetime and the standard model emerge, but with pre-determined values of coupling constants. Fermions span space-time as well as the space of the gauge fields.

Taking the square root of Minkowski space-time does not involve change of energy scale. It only gives a more precise mathematical  formalism. One that is key to unification, which already takes place at low energies, if we do not restrict ourselves to 4D classical spacetime: only classical systems live in 4D. Quantum systems always live in E_8 x E_8 even at low energies.

It is tragic and unscientific that one should want to outright dismiss a numerical expression for the low energy fine structure constant; it only reflects a deep-seated prejudice.

== Calculated value as 1/137.04 ==

Hi, {{U|LaundryPizza03}}, I didn't put the formula with the source into the article (IP user did), but I did calculate its value from it (with the Julia language):

<code>
julia> using IntervalArithmetic <br>
julia> @interval 1/(9/1024 * exp((1/3 - √(3/8)) * 2/3)) <br>
[137.04, 137.041]
</code>

this differs by 0.003% from the (too precise) CODATA 2018 value (I changed the article here to be consistent with that (measured) CODATA value AND this theory). I would really like to know if there's ANY other theory for the constant, than this [[octonion|octonian]] "pre-quantum, pre-spacetime theory". Measured values do not trump (good) theory, because all physical measurements also depend on theory. Some IP user put the source in (its only edit), but if the IP hadn't put it in, I would have.

:::::While this is an old discussion, let me throw my two cents in: The overwhelming consensus among the physics community is that the fine structure constant can not be calculated, only measured.  To quote [https://www.quantamagazine.org/physicists-measure-the-magic-fine-structure-constant-20201202/ one realiable source], “Physicists have more or less given up on a century-old obsession over where alpha’s particular value comes from; they now acknowledge that the fundamental constants could be random”.  However, a Google search of the fine structure constant will find dozens of self-published papers and blogs showing how this number can be calculated.  Given its current known value—137.035999—one can come up with a number of equations that get that value.  And, yes, many many people think they have unlocked α and will get the next Nobel prize for doing so, to the point they will [[Wikipedia:Sockpuppet_investigations/TejinderPSingh/Archive|disruptively edit the Wikipedia]] to tell the world of their “brilliant” equation which solves the fine structure constant.  While “crackpot” is a very negative and hurtful word to say, I can see why some people throw in the towel and resort to that kind of harsh language every time someone comes up with a new way to calculate the fine structure constant.  I think it’s important to try and use kind and loving language, so do not approve of a word so harsh, but I also feel accuracy in the Wikipedia is very important, and having yet-another-how-to-calculate-α recipe in this article will make the article inaccurate and unscientific.

::::::Kindly do note that the octonionic theory is a new theory of unification. It is not a recipe for calculating the fine structure constant. This constant is only one of several, including mass ratios, which get determined in this theory from first principles. There is nothing particularly special about the fsc.

== "early 21st century" error ==

"In the early 21st century, multiple physicists, including Stephen Hawking in his book A Brief History of Time, began exploring the idea of a multiverse"

According to our article on the book [[A Brief History of Time]] was published in 1988, not in the early 21st century. This probably should say "In the late 20th century" - using "began" already implies it continued after that.
