Math, Music & Nature's derivation of 'Phi'
Nature's smallest & best kept secret -
the 'divine rate' at the heart of organic growth . . .

This simple & beautiful mathematical truth is not in conflict with the basis of any religion or of
any reputable science,
humanist or otherwise.
If anything it suggests that at a seminal level, the dichotomy between science and religion (created by humans) is false . . . .

The 3-2-1 'Hemiola' - a Trinity of Wholeness - the First Law of Theoretical Physics

Pythagoras’ famous ‘string experiment’ from around 530 BCE, demonstrated relativity where: -

if a string of constant length and at constant tension vibrates at 1/1 it gives One Fundamental @ 100 Hertz

is divided into two 1/2 lengths, the rate at which each 1/2 vibrates doubles& gives Two Perfect Octaves (with the fundamental this is the 'Tonic') @ 200 Hertz

is divided into three 1/3 lengths, the rate at which each 1/3 vibrates trebles& gives Three Perfect Fifths (with the 'tonic' this is the 'Dominant) @ 300 Hertz

THREE vibrating in the time of TWO vibrating in the time of ONE is called in music a ‘HEMIOLA’.

In 'stringularity the Fundamental, the Perfect Octave & the Perfect 5th are in a 'Tonic:Dominant' relationship'. This combination gives rise to the basic functionality of music harmony, the 'Perfect Cadence' like an 'Amen' cadence, or where the dominant is drawn to resolve on the tonic.

In 2010 particle physicist Stephen Hawking stated that we can call this, ‘the first instance of theoretical physics’.
In fact and in common with many other physicists who routinely cite Pythagoras, this acknowledgement draws well short of recognizing the profound structural implications of this 'instance'.

The Derivation of Phi "Nature's most Beautiful & Best Kept Secret."

Stringularity also gives rise to 'Phi'. Given the universal significance of 'Phi', or the 'Golden Rate' (discussed in more detail below) this 'Phi' derivation as a rate is simple, subtle and axiomatically obvious and yet it is still "Nature's smallest, most beautiful and best kept secret."

'Stringularity' & 'Perfect Tuning'

In music this 'Stringularity' is quite simply the ‘First Law’. It gives rise to ‘Perfect’ or ‘Pythagorean Tuning’ where the intervals between the notes within the octave being different for the seven tones and ‘semi-tones’ arising. This roots music played on an instrument that is tuned ‘Perfectly’, firmly in the key of the scale in which that instrument is tuned.

In classical Greek music this procedure gave rise to the 7 'modes' (Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian & Locrian) each one starting on a different one of the seven available notes in the scale, but while maintaining the order of the tones and semitones arising in the scale.

Well Tempered Tuning

Around 2,225 years later ‘Equal Temperament’ or ‘Well-Tempered’ tuning was consolidated in Western music with J S Bach's ‘Well-Tempered Harpsichord’ (1722). It eventually comprised the ‘48 Preludes & Fugues’ (four in each of the 12 keys available within the 'Perfect Octave') physically requiring ‘Equal Temperament’ or ‘Well Tempered Tuning’ of the Harpsichord - the tuning of each of the 12 semi-tones within the Octave was tuned so as to be in equal steps.

In both of these tuning systems a ‘Perfect Octave’ is always a ‘Perfect Doubling’ and this governs all tuning systems of the parts withing the octave. In Well Tempered Tuning however, a ‘Perfect Fifth’ becomes a ‘Well Tempered Fifth’, comprised of seven of the 12 Well Tempered or ‘equal’ semi-tones within the 'Perfect Octave'. In other words, this ‘Well Tempered Fifth’ becomes marginally smaller than the ‘Perfect Fifth’.

Well Tempered Tuning and the Pythagorean Comma

As the Bach Preludes & Fuges show, well-tempered tuning is a response to the Pythagorean Comma that roots the instrument equally in any of the 12 keys available on each of the 12 semi-tones within the 'Perfect Octave'. It shows that music can be written in, played in and modulate between any of the twelve ‘keys’ available within the 'Perfect Octave'.As this remains 'in-tune', well-Tempered tuning remains the basis of Western music to this day.

Like an orchestra playing in in tune and in time together, this Well-Tempered Climate Accord enables the carbon-contraction-budget to be ‘created and performed’ at whatever rate (or in whatever key) that science requires; in other words as a complete UNFCCC-Compliant 'event' (vide Adair Turner UK Climate Act).

So the primary purpose of Well-Tempering the 'C&C' Climate Accord is practical and not ideological. It is so that any convergence rate to equal per capita rights can be negotiated, while remaining an axiomatically self-structuring and self-limiting function of the global contraction-rate that the precautionary policy requires. At root level this is governed by the stringularity law - here simply double the rate halve the weight.

The ‘Pythagorean Comma’ has a much greater significance than has yet been widely realised. So at this point it is perhaps worth bearing in mind this foundational challenge coming quite separately from Richard Feynman and from John Archibald Wheeler.

The Pythagorean Comma axiomatically gives the derivation of 'Phi'

The 'Pythagorean Comma' is usually understood as a ‘gap’ that emerges between 2^7 (seven Perfect Octaves) compared with 1.5^12 (twelve Perfect Fifths); in other words they don't quite 'commute'.

These create a rising & widening Hertz differential and when this differential sequence of rate values is fed back on itself (dividing the 12th value by the 13th, the 11th by the 12th etc) 'Phi' - but also the derivation of 'Phi' - emerges.

In other words 'Phi' is a simple function of the first three integers as per 'Stringularity', or the first law of theoretical physics.
'Self-referentially' this feeds back between zero and ‘Phi’ or 0.618 and from this one might say the 'origin' & derivation of 'Phi' if profound, are not quite so 'mysterious' after all.

Then there is the fascinating matter of where the so-called 'Cosmological Constant' exists in relation to Phi. Phi is at 137.5079° or 0.61803.... the value for the 'Fine Structure Constant' quoted by Richard Feynman is at 137.03957 or 0.61934452.
Though the precise value of FSC is still debated, even to the extent that it is not always strictly regarded as even exactly 'constant', 'Phi' and the rate of its derivation is certainly axiomatically constant. That said they are very close and both are contained precisely between the 12th and 13th steps of the Pythagorean Comma.

They are not 'identical' but the are very close. Also, if the Phi position emerged 'arithmetically' at the inflationary moment after the the big bang, the FSC may not be quite 'constant' as it is being measured on today's photon/electron exchange 13.8 Billion years later, in a universe that has been expanding since inflation and where 'the musical curve' itself has been expanding but decelerating very gradually from 0.618 to 0.666 (as shown in the charts below).

Electro-magnetically, the influence of ‘Phi’ is evident throughout nature at every scale of time & space. This evidence of 'Phi' is often seen, heard and felt as 'awe-inspiring'. From the spiral of galaxies to the double helix of DNA, 'Phi' is dynamically encoded in the simple, subtle, self-structuring and self-limiting growth patterns of sunflower seeds, pineapples, fir cones, the human cochlea - in a phrase it is axiomatically encoded in Nature at all scales.

All from the 'Hemiola' - truly awe-inspiring . . .

From zero to one; so what really happened at the Big Bang?

At the core 'Phi' and the First Law of 'non'-theoretical physics is the source of all we have: -

Some people ask, "what has music got to do with climate change?"

Perhaps instead one can ask, are ‘Stringularity' and the Golden Rate/Ratio what drive musicians and especially perhaps string-playing musicians, to measure the fine structure of frequency governed this way with such minute accuracy?

And as a consequence, is the ‘living music of Phi-the-rate’ that emerges from ‘Stringularity’, a key to the resilience of ‘the Well-Tempered Climate Accord’, a methodology for collective global action to cut carbon emissions in time to keep in tune with the planet, other life-forms and ourselves, failing which a catastrophe looms (Sir David King)

Often known as ‘Contraction & Convergence’ (C&C), after thirty years this Well-Tempered 'C&C-methodology' remains robust, widely supported and unchallenged at a fundamental level.

Richard Feynman, one of the originators and early developers of the theory of quantum electrodynamics (QED), referred to the fine-structure constant in these terms:

"There is a most profound and beautiful question associated with the observed coupling constant, e – the amplitude for a real electron to emit or absorb a real photon. It is a simple number that has been experimentally determined to be close to 0.08542455.

My physicist friends won't recognize this number, because they like to remember it as the inverse of its square: about 137.03597 with about an uncertainty of about 2 in the last decimal place. It has been a mystery ever since it was discovered more than fifty years ago, and all good theoretical physicists put this number up on their wall and worry about it.

Immediately you would like to know where this number for a coupling comes from: is it related to pi or perhaps to the base of natural logarithms? Nobody knows. It's one of the greatest damn mysteries of physics: a magic number that comes to us with no understanding by man.

You might say the "hand of God" wrote that number, and "we don't know how He pushed his pencil." We know what kind of a dance to do experimentally to measure this number very accurately, but we don't know what kind of dance to do on the computer to make this number come out, without putting it in secretly!"
