The rotations in the above demonstrations of Pythagoras theorem and its general counterpart are rotations of a quarter arc or a multiple thereof , and the sum of the rotations clockwise + counterclockwise sum to a quarter arc or some multiple thereof.

The significance of this is simple : the quarter arc is a fundamental Rotation in any metric based on Pythagoras theorem, thus the appearance of i as a complex symbol in the quadratic and above solutions testifies to the necessary rotational transform in order to " solve" or rather " liken" or " equate" square magnitudes.

It will turn out that for non Pythagorean triangles the cosine of integer multiples of angles takes on that role and thus the roots of unity so called represent arc rotations of less than a quarter arc, but still symmetrical divisors of the full cycle.. These roots of unity become zeroes of space in the n- step/ rank systems, signifying what Norman calls the dual notion of perpendicularity, but which is rather the general notion of a zero result for the cosine ratio.

In Euclidean space we define the cosine by the right triangle, but if we define the cosine by a more complex form  we can define it on an integer multiple angle or arc and that relationship creates a fractal rotational scaling that is so beautiful and surprising that it takes your breath away when imaged.

We will soon realise that Hermanns product designs naturally tessellate the plane, dividing it into " cells" which are often exact copies of each other, and these are subsystems within systems. The beauty os that complex product designs can produce " almost self similar" regions that vary in fascinating emergent ways when iterated.

The introduction of the term "factor ", during the multiplication discussion carries into Hermanns Methid some undefined conceptions especially regarding Pre and post subjugation. However what has just dawned on me is that Hermann has designed the product rule in the guise of a factorisation rule!

Factorisation derives from division. In that case one divides a larger whole by a smaller whole, counting as you go. Eventually as you divide off the larger into these smaller sized chunks the chunks acquire the name factor, because the whole is factored or broken down into smaller parts( fractli)  but these parts are made( factum) by the process.  Factorisation therefore is a division process. But now we write the factor pair as a product or multiplication, that is representing the result of a second step knitting.

Where does the factor pair come from? By counting we record or name the number of facta , that is forms made by splitting off pieces the size of the divisor. That count is called the dividend . The divisor and the dividend form the factor pair.

It turns out that if the divisor goes into the whole an integer number of times, then one can find another divisor that cord into the whole an integer number of times . In fact several differing whole number arrangements producing the whole are feasible, thus giving several factor pairs based on that original divisor.

But a special case exists: that is where there are no other arrangements based on that divisor, and you get only one dividend. Such a case is called first Arithmos. Proto Arithmos.  They received this name because in the logos Analogos Method these Arithmoi take the first ot protos position . Thus the logos consists of first and second position: the dividend and divisor take those positions. The analogos consists in the third and fourth position , a factor pir are placed in these positions Fir comparison and contrast.

This process is explored in great length in books 5 and 6 of the Stoikeia. The resultant output of the process is like or differing. If Differring which is the smaller of the 2.
This is the process of proportioning, that is Reasonng or employing rational thought patterns. Books 5 and 6 are one foundation of the Pythagorean dialectic that trains one to think rationally . This was markedly different from Aristotelian logic based on linguistic and grammar analysis.

So what is presented as multiplication is clearly factor pairs from a division process.

Can the factor pairs be switched round?

In practice that is asking is there a divisor that is inter communicant with the count result in such a way that the dividend obtained using it is related to the previous divisor by the same count name? In reality it is a question about co commensurability.  This of course is commutativity , but in general the dividend and the divisor cannot be interchanged. When they are interchanged it physically means we form the whole by multiple parts of the " dividend" being knitted together. This is a different concept to product design by subjugation..

Subjugation restricts thought patterns. Pre and post subjugation issues exist in the division algorithm . Which divisor one uses effects the output result so interchange of divisor is not generally invariant. But if we rewrite it in the product format, because the whole is invariant then divisor and dividend can be interchanged in this product format..

So we have an inconsistency hidden by the label design for the product of factors. And the backwards looking nature of the design, looking back to reconnect to division. The factories are actually not just forelimb and hindlimb but divisor and dividend, and thus by that nature they correspond not to a synthetic knitting but to an analytic one. Thusly the order of writing becomes very important because generally as in all analytical knittings the resultant is one-assigned, that is a unique value to each unique ordered arrangement in the paired format. The analytic knitting thus permits two inter communicant but differing searches with unique outputs. However in the case of divisor and dividend if we fix the object being divided, initial whole, then we can actually vary the divisor, which thusly varies the dividend, and this is how we form our Factorisation Tables( rather than multiplication tables)!

But then through proportion of these divisor variations we can alter the size of the resultant product, that is the initial whole , no longer assumed as fixed, can now increase or decrease in quantified magnitude proportionally. And this relates to commenurability in that we can also allow the tally count to increase in this proportion or maintain the tally count name by increasing the quantified magnitude of the divisor in this proportion.

From this we can take to our sides ( draw out an interesting phenomenon) that the resultant output of the analytical knitting of division may in facy be MULTI-assigned., and so we have to additionally constrain it( by equivalence lasses) into its standard one-assigned format.

By choosing to write the product design as forelimb and hindlimb written side by side without any visible sign we obscure the fact that these are divisor and dividend written together, and there is a deeper connection between them based on factorisation. Calling them factors was meant to recall this deeper relationship, but in fact convention and general useage has altogether subverted this meaning in the context of " Multiplication".

Factors as currently understood are indeed interchangeable, but that is not a consequence of multiplication, rather it is a consequence of division due to divisor magnitude change, and the representation of this magnitude by a commensurable divisor or unit, that is Monas by name.

Monas is the same as Einheit, and it is that indivisible whole used to count everything else in a given system. It is the standard Metron for a system. But it itself is free to vary whimsically! Monads are thus set by assenting to a convention agreed among those who seek to utilise it. This is why every sovereign nation has a functionary responsible for weights measures and time, all metrical standards set by a sovereign nation, and often imposed by conquest of or adoption by another national state.

Lately the international System of units has bloodlessly been adopted by scientists around the world, but you cn still find national measures reasserting their sovereign patina as emblems of national pride and identity, such as the £,$, °F etc.

The use of commenurability to define factors numerical names or numerals has also been a big factor in obscuring the role of divisor and dividend. Thus by habit we have called multiplication an inverse process to division, but payed scant attention to the true nature of that reciprocity. In practice we have ignored minor incoherences in order to build a " logical" structure that is linguistically systematic. However we should have built a structure that is dialectically systematic built on geometrical or spaciometric behaviours, not grammatical or linguistic ones.

Justus Grassmann came up against this issue precisely in attempting to define the logical equivalent of multiplication. He could not. He simply had to exhibit it geometrically. Hermann on the other hand was able to derive a systematic design for multiplication based on a dialectic approach, as we have seen. The design of a product was thus revealed to be a design issue with many constraints and behaviours to account for.

But now deeper than this we find that the notions of divisor dividend and commenurability by a common monad having been worked out by the Pythagorean school have through slovenly practices been obscured, and easy attributes like commutativity have been incorrectly employed without proper design demonstration from first principles. In fact, the whole basis of the design was shifted onto some linguistic markers called numeral, representing some notion of accounting for real object , things and magnitudes, but without due care and attention.

In general then multiplication appears commutative, but in real physical Geometries this is not the case because of division, the Ultimate meaning of subjugation! Multiplication in general physical situations is of 2 types, Pre-subjugate or post-subjugate, a fact that surprises Hermann and shakes him to his very psychological core!

The general Doctrine of the Thought Patterns (Ausdehnungslehre 1844)

§11. Empowering completely generally For the Division ,  now desiring   its  result to be  one-assigned or multiply-assigned , the rule of the dividing into pieces of the dividend, specifically


      
Quote
 "(a+–b)/c = a/c +-  b/c "

But whereby considering, we have yet to remark, that,  for the multiplication in the general rule of the dividend there, everyway toutable( for exchange)  quality of the factors would not be taken to ones side (for scrutiny ), also in the general rule 2 artforms of Division must come to be, each of the artforms  becoming sought concording to the entity , specifically the forelimb or the hindlimb of the multiplicative knitting.

There in the entity format, both factors have a like relating to the addition and subtraction, thus this relationship also becomes empowered by both arts of the Division ; and   if the above rule is outwardly demonstrated for one artform, thusly it becomes out of the same grounds also to be demonstrated for the other art form.

We will to take to our sides ( in scrutiny) , let it be the forelimb sought:

Therefore if, to the "by considering game",
a/•c = x exists, thusly let  be xc = a

Hereconcording a + b/•c  is assigned the identified thought pattern by it , which as forelimb multiplied by c gives a + b.

I can initially sunder each thought pattern into 2 pieces, of which two one entity  can arbitrarily become taken to ones side( for scrutiny),. Therehere let   the sought entity with a+ b/•c like-set thought pattern be it:
  =( is like) a/•c + x

Now this like- set entity as forelimb multiplied by c gives concording to the foregoing § a + xc
Therefore it should give by consideration of this multiplication
a + b

It is following like

a + xc =a + b ;
That brands  
xc = b,  x = b/•c

Therefore the sought thought pattern , there it   (=) was like a/•c + x set , ( exists) like a/•c + b/•c

Upon the same manner the rule outputs itself  for the Difference(subtraction).





Footnotes

• Everyway like to the annotating to §7, and the Ausdehnungslehre of 1862 No. 377 up to 391.  (1877)
••where the "•", the dot in the divisor the place of the sought factor besigns!

Commentary on §11

As discussed in the previous post, the general rule for the dividend does not account for Pre and post subjugate multiplication, and that 2 artforms or skill sets are therefore going to be be essay to do division in Hermanns method, for Hermann does distinguish between multiplication as a a subjugate forelimb or as a subjugate hindlimb! Take very careful note of the footnote. The • signifies which limb the dividend actually represents, even though the divisor cis precisely the same !  Because of commutativity we completely miss this distinction, which arises out of the product design requirement for subjugate systems.

So when thinking of the dividend format, otherwise called the Quotient format, do not go to the " answer" but rather linger at the factorisation stage. Look out for the divisor and the dividend in their guise as factors, and consider which is subjugate to whom?

Hermanns examples are given for the forelimb case, that is the divisor is post subjugating the forelimb, thst is yo be clear, the forelimb is subjugate to the divisor in the system within system set up.

The more I think about Pre subjugation and post subjugation in relation to multiplication, the More I realise why Hermann was shocked by the failure of the commutativity convention. The Pre subjugation gradually resolves itself isle tidally into the role we now assign to the function notstion. The post subjugation resolves beyond multiplication into opposition of processes., although some prefer to assign that composition role to presubjugation..

The subtle differences are due to order of process, and what impact that has on the resultant out put and the constraints it imposes in performing the process.

The facility of the mind is apt to slide between the two with little trouble, giving the appearance of ease, but in fact when one comes to grapple even clockwise snd counterclockwise denotations one realises what a struggle this is to communicate without coercion! One physically has to hold another to the same point of view to communicate this distinction unambiguously. Like wise when a system within a system is set , it perforce is set by Pre subjugation or by post subjugation. Presubjugation would be like top down planning while post subjugation is like top up constructing. In fact the initial design by Hermann heavily implies synthesis from the bottom up , while Analysis is from the top down ( auf-lösung).

The subtlety comes when one inadvertently switches factors as labels around in a system. One simply " forgets" the system has a preset subjugation and factors are bound by that, so switching factors is not possible within a real system. What can be done is relabelling.

The question is what kind of relabelling? The answer is cyclical interchange. As a resolution to the problem this is the simplest, but has the consequence that BA = – AB , specifically in the plane where Multiplication has its first derivation.

But of course one tends to overlook this until one is forced to confront it. The definitions of post and presubjugation obscure this issue which arises not in the general Analysis, but in the specific synthesis.

What practical or pragmatic difference does it make?

Well in certain theoretical systems none at all, but that is specificity. The issue is un generality. One must not in general assume commutativity. But one must define post and Pre subjugation and work out the impact of interchanging factors would be. In so doing it is as well to note that the "—" minus Foresign does not rigidly sign the oppsite in a Grassmann system, but rather it is a sign indicating an orientation change . It just so happens in a step 2 system that that cyclical change alternates between opposite directions  as it goes around the parallelogram. In more complex systems that sign can be replaced by a root of unity, which will in fact act as an orientation marker.

The work done on poly signs by Tim and Kujoni explores this issue . For me the underlying issue to thst solution was the meant of i, but bow that has satisfactorily been resolved into an arc segment and a distinguished axial orientation in space. Both the arc and the axis lie in the same plane, and this becomes a fixed convention in Hermanns discussion of quaternions.

However Hermann utilised this convention in his paper on the Ebb and flow of Tides.

The general Doctrine of the Thought Patterns (Ausdehnungslehre 1844)

§12. The in the forgoing paragraphs presented rules  express the general relating of the Multiplication and Division to the Addition and subtraction.

Afaroffagainst, the rules of Multiplication aside themselves do Not go henceforward out of this general relating! how the arithmetic  sets it  out, and which rules declare the everyway toutable for exchange property, and the everyway unionable property of the factors

And are therehere also Not evoked through the general  label of the multiplication .

Much more  we come to learn to know artforms of multiplication in our expertise ,
by considering which artforms:

 the everyway toutable for exchange property  of the factors finds not a place by the least entity;

therefore by which, (By considering which artforms):

  all up to here set out proposition still have their full application .

Also we have thuswith formally evoked the general Label of this  multiplication.

A real label must inter communicate to  this  formal label, if the Nature of the knitted magnitudes is given,  which label declares the creation whole manner of the product, everyway mediated by the Factors.

The relating to the real addition delivers to us a general concording  to this creating whole manner,

 specifically, one of the (real) factors becomes apprehended   As sum of its parts ( concording to §8),

thusly must one place  the  Sum ( factor) of the " product representation forming ", " creating whole" manner concording to the general set Relatings ,  in order to subjugate ( it)  

the ( real) parts of the same manner are able  to subjugate,

and the thusly formed representational Products are able to  add;
 
that brands: there these products once again as "in like sense  created":

 they as parts  are able to knit together to a whole;

That brands: the multiplicative  creating whole manner must be from the artform, that the parts of the factors  go into it on the same manner,

thusly specifically , that if a part of the one is multiplicatively  knitting  together with a part of the other,  
(if a part is creating whole any random magnitude),

Then also, (by considering the multiplicative knitting together of the wholes),  each part of the first factor   with each part of the other factor creates whole such a magnitude, and  indeed the same magnitude,  if these parts are like to the initially taken to oursides for scrutiny parts.

And  it enlightens thuslike:  
that  if
the creating whole manner  has the given to us property ,
also
the multiplicative relating has  its inter-communicant  "knitting together manner" relating to the addition of the like artformed entity ,
and  thuswith  

 all rules of this Relating empower for it.

Also We name therehere already such a Knitting together manner, then,

only if firstly its multiplicative relating to addition of the like artformed entity is concordingly demonstrated,'
or in other words,
only if the "like ingoing" of all the parts of the knitting together limbs in the knitting   is firmly placed in the above given to us sense,

a Multiplication.


The untilhere Presented general knitting Rules satisfy in the essential entity for the  presenting of our expertise, and therehere we go over to this .

Commentary on§12

This concludes the 3 part lead into the Ausdehnungsgröße. A historical presentation has been succeeded by a formal induction, and the 2 have,  compared and contrasted, identified some very general rules, propositions, labels nd thought patterns. The rules of knitting have been presented and a brief sortie into how these rules are applied to real systems , and what tests they must pass before multiplication can be formally ascribed as a label of a relevant process.

The approach which progresses by stages from addition to Division, focuses on the importance of the product design using subjugation . The last paragraph(§) really emphasises that Arithmetic is a related but fundamentally different system, based on differing unles to Grassmanns Methid, but yet his system demands the designing of a relevant product that meets the formal criteria before it can be called multiplication, and also any real system must conform to the formal rules before it can be called Multiplication. That may or may not include commutativity or associativity ( everyway union ability), as those properties derive from the nature of the magnitudes not from the rules of multiplication.
I will now turn to the paper on quaternions , leaving the Ausdehnungslehre to the Fractal foundations thread.

The labels of " everyway tout ability for exchange" and " everyway union ability" are labelling concepts that as we have seen, derive from per mutability within sequences ans every way combining within sequences. Thus the foundation behaviours of Hermanns methods are the processing sequences of any kind dealing with any labelled object or idea , particularly involved in analysis and synthesis.

To these process sequences Hermann adds certain constraints as implicitly or explicitly suggested by the nature of the objects or the goal of the process. The overall goal, as you may recall from the induction, is to establish rules that make sense of the processes around us, and divert us from unbearable confusion. Thus we deliberately remove ourselves from a extremely wide range of confusing processes and behaviours in order to construct a rule governed model.

The rules we create and the constraints we set are of our own devising, no matter how closely they produce results as found in the natural behaviours around us. The resultant outputs rather than telling us more about " infinity" tell us more about ourselves and how we work. Thus we can learn to know many different products of our own design that we may also call multiplication!

One starts with a real experience.

One becomes aware of a scatter of points a confusion of elements. Maybe they were just there all along, maybe they are the result of a deep and prolonged analysis finally coming to a halt because it can go no deeper, no further .

A point is that which has no parts!


We begin to sequence the points, to union them into groups collections sets, sequences and links that whimsically conform to some inate intuitive rule. That is when we synthesise some entity from the. " chaos" of points . That is when we realise that the analysis was the easy part!  That is when the everyway tout ability of the connections , the everyway unioning of the points in synthesis becomes overwhelming. The permutations of a combination of points the unionability of an association of points becomes scarily large!

The analysis of an entity does not increase our understanding of it, it increases our confusion! Our understanding becomes clear only in limited and constrained circumstances. Thus understanding is in fact an imperfect view or take on reality. It must perforce ever change , always move to a higher level if it is to remain utilitarian.

So we understand only a very limited , constrained set of elementary relationships, the trick is to make that structural understanding apply to as many different levels as possible, to make that structure iterate and reiterate in every circumstance and at every level that we can.

What we are doing is replacing a full panoply of life giving experiences by a paltry set of extremely limited tools, in such a way that we can approach any aesthetic circumstance and begin to grasp how wonderful it is. But some have taken their eyes off the beauty that is all around them, and called meagre and thin scratchy symbols the essential beauty!

If the darkness is now seen as light, then how great is that darkness!

From our synthesis we establish formal design rules. Such rules are to help release the artistic potential of the designer, to allow such a one to model, sculpt and display some aspect of the wonderous mystery in a fabulous light, in a system that enhances not obscures the wonderful nature of spatial magnitudes, and their inter relationships and dynamic transformation.; and yet still a copy of the inimitable splendours of real experiences.

The unioning and the sequencing of points in space is the basis of our Spaciometry . We choose one entity as a Monas or Metron for all, and so commensurately count space, trigonometrise geometry. And then we get " lost" in the rhythms nd relations of counting, the great hymns to the Vedic deities, the honorifics to the Muses. And still what we have done , achieved and laboured over is scant, scrawny and vanishing away into nothingness if that were possible ( but it is not).

The combinatorial relationships of the Grassmann design recommendations reveal the fundamental nature of the Binomial theorem and series and expansion to all of our methods as formulae. At a very basic level sequences and permutations are the fundamental structures of our symbolic formulary.

It should be no surprise therefore that all our important formulae depend on sequences, permutations and combinations of symbols.

Let not the symbols be a door, but rather a balcony that looks out onto a vast and beautiful plain!

Proof by algebraic computation!

Normans whole design of products is now revealed. He is matching the rank arrays and product designs to what suits a computer process optimally. Consequently we have to review the word " calculation".

Wolfram Alpha and Mathematica use the notion of computability, again a difficult concept to define now computers are no longer polynomial crank machines turned bt hand or steam!  However if you hold on to hat polynomial algorithm you will get the best idea of what computation or calculation means.

<a href="http://www.youtube.com/v/ZeTTtz&rel=1&fs=1&hd=1" target="_blank">http://www.youtube.com/v/ZeTTtz&rel=1&fs=1&hd=1</a>

Algebra, which Descartes labeled  La Geometrie is a development from Bombelli, Harriot, Viete, De Fermat  of formerly geometrical problems and issues.  The method , though extremely powerful and general is very laborious and labour intrinsic e in terms of Coordinates. Leibniz felt we could move beyond coordinates to representations of the cdual magnitudes.

Hermann as we shall see moves beyond point coordinates o representations of magnitudes. However he develops this on the bedrock of points, and the intensive magnitudes. But as we saw Hermann determined that points and line segments are represent able by the same magnitudes, the Combinatorial thought patterns.

Here Norman uses his own mix of these ideas and labels to develop Rational Mathermatics. Over time I will see if this truly reapplied Hermanns concepts or whether it is a radical re evaluation of Hermanns method analysis and synthesis.

I apprehend now the role of 3 elements in the overall design of a system in which synthesis and analysis must take place or have an expression, and in which also a subjugating synthesis must take place and be of a next higher " rank" or type, and which synthesis must support a next higher rsnk of analysis in an inter-communicating way.

These next higher knitting designs are called multiplication and division in the system if they satisfy or please certain constraints on " formal multiplication " in its relating to addition or subtraction.

I have also looked at the signature or the centripetally acting quality , or the centrally active property of a systems designed product, –1, 0 , 2 (or as some prefer 1).

When set out in a rank array or Cayley table these form the central diagonal evaluations/ property / quality. To tie them hard and fast to a numerical meaning is misleading, although of course in a metrical system this is a useful and powerful simplification, and allows algebraic manipulations or processes to be done, and like and differing outputs to be crisply distinguished.

Because Hermann has given a foundational explanatory role to synthesis and analysis, he also has to evaluate the property or quality of the sum of these centrally acting products to complete the product design. This constrains the behaviour of the sum of the next lower level elements without actually needing to specify precisely how , because that is imposed from " above", and worked out concordingly in the full specification of the designed system, by working through a few special and useful generalities.

In looking at this formal product design process it struck me that a product design relevant to a fractal generator is the iterated " function" design at the core of the iterative process. A little thought should make clear how z = z + c is a fundamental synthesis , but which is clearly recursive or iterative ;
and  z =z2 + c is a product design which is again recursive with constraints
z.1 = z.z + c.1 to conform to the general product pattern c(a + b) = ca + cb at least by analogy.


The use of analogy, you may recall is a basic skill in the toolset of this Expertise.

I have consistently translated Begriff as label, but the better apprehension is a handle attached to some entity  so that it uniquely identifies that entity ( as a label) but also enables us to manipulate the entity according to its nature, or notion . As we are sometimes not clear about a notion, and indeed may label the precisely identical notion severally, it is important to be rigorously strict in our interpretation of the labe, often having to demonstrate that one label is identical to a number of other seemingly distinct labels, when and if they are.

So the signs and labels and symbols form a formal model of real dynamics and behaviours and kinematics, conforming to " common" mathematical liturgies, but rigorously defined at the design stage by the designer and therefore pertaining only to that interpretation. No matter how familiar a string of symbols look, using the method of Grassmann constrains the interpretation of and the application of the labels.

The Place of Hamiltons Quaternions in the Doctrine of Extending/ Extensive Magnitude

By  H. Grassmann.   In Stettin
--------------------------------

There is only the One arbitrary Scruple the Doctrine of extensive /extending magnitude makes, specifically that:
it gives magnitudes, which magnitudes are themselves let derive numerally out from more than one Monad;
and it from there advances out in completely objective manner ;

Thusly  all expressions must,
which expressions are numerally derivable out of an Accounting Tally of Independent Monads, and therefore Also the Hamiltonian Quaternions,

have their appointed Place in the doctrine of the extensive/ extending Magnitude, and first find  their expertise-like foundations in it.

This is until here not outwardly known, and Goran Dillner in his  enriched teaching offprinted-handling  overgoing the quaternions ( Annals XI, 168 f'f.)  does not one time outwardly dream of the doctrine of extensive or extending magnitude,

If-like, he derives a complete array of propositions out of the theory of Quaternions , which propositions  are already in my Doctrine of extensive magnitude from 1844( &1),

and thus-plainly,  in the later redaction from 1862 (&2) , have found their much simpler , and out of the "Nature of the  matter" root-shooting, founding activity.

Also it is like everyway throwing it, and the Doctrine from the quaternions has been less like  furthering it , that, concording to Hamilton's progression of it,  one has besigned simple and long familiar labels with new, openly right unsociable names , how " Vector" places in " line segment", " tensor" places in "length" or " numeral Value" (&1, 414) and so further.

The Hamiltonian Quaternions root-shoot out of one of the Multiplications( design products), which  ( in my offprint-handling  " Sur les differents genres de Multiplication"  in Crelle's Journal  Bd. 49  S. 136 ff,) I presented, and  which  I have tied up beside the 3 "likenings" groups ( groups of equating)
(1)e_re_s = e_se_r
(2)e_re_s + e_se_r = 0; e_1^2 = e_2^2 = ....= e_n^2
(3)e_1^2 + e_2^2 + ....+ e_n^2 = 0

Where e_1, e_2, ....,e_n the independent from one other monads besign, and  e_r and e_s besign 2 whimsically   differing from one other of these monads ,

and indeed  the quaternions tie themselves up   besides the multiplication, for the case that n = 3 exists;
constraining likenings( equations) form a  representation of  the  quaternions , the Middler of those 3 groups.

Commentary on page 375 of the annals of 1877

Hermann here critiques Dillners presentation of the Quaternions.

Firstly he criticises the Prussian predilection for preferring foreign ideas and presentations to the less "grande" Or less "international" homegrown variety. Second he is not impressed by the Unsociable or unfamiliar words used in place of more familiar and simpler ones. Thirdly , Dillner does not even dream of mentioning the more general and foundational propositions of his own 2 works.

This then is a nationalist appeal to his own countrymen to support and promote homegrown talent .

It is to be noted that Hermann does not claim he discovered Quaternions at the same time, at least in writing, as Hamilton did. No, rather he says this work of Hamilton ought to be deriveable from his more general theory in a more straight forward manner, and that should be plain from his previously published results on the different product design types of multiplication, as well as the one Scruple of the Doctrine: the design of all magnitudes and any magnitude!.

The interesting take is on the numeral design of these magnitudes ( Arithmoi). This design is drawn from an account tally of all the differing magnitudes, very much like a till receipt from supermarket..

Hermann now ties these various product design concepts ( multiplication genres) to 3 groups of equations or better likening methods.

If we relate them to a Csyley-Grassmann table we see they are characteristics of the diagonal and the off diagonal entries or elements.

Quatenionic present themselves when the account tally for differing monads is 3. And the tying up of them occurs then, but the product design is represented by a group of constraining likenings( equations) . Consequently the product is a "Middle- man" or intermediary one!

Consider that Hermann dedignsted the " aussere" , "innere" and now the "mittlere" products and you hopefully get the picture that the mittlere product design is some mediated combination of the other 2. Thus to mediate the product one must perform a quite complex task. The product design is thereby no simple arithmetic average or even an algebraic average. It is a mediated combination of 2 well defined products and the essence is in the detail of that mediation process!
