Of Logarithms and modulo/ clock arithmetics.
Aggregation is usually notated with a + symbol, but this activity is far from simple and far from binary. It is algorithmic in nature and is different to measurement.
Measurement is an activity of apprehension, of response to the environment, of applying or observing the application of unity to a form in plethora, a sensing of the structure and construction of a form by application of the unit measure, or by watching how the unit measure populates a form dynamically.
Aggregation is an activity that we perceive as happening to all sorts of things as they gather or are gathered together.My perception links, yokes, ties things together in a subjective collection. I may even perceive or draw or define boundary or an envelope for the aggregation that dynamically changes.
Dynamic as these forms structures and aggregates are i still perceive a static form as a resolution, or a completion, a whole an answer a sum etc.
y perception of aggregation and measurement is therefore dynamic and i only "know" when i have an answer when i stop, or it stops being dynamic and becomes stable or equilibrium.
The dynamism allows for rhythm and motion and dance and song and metre and ritual and repetition, iteration and convolution and poetry and rhyme of drawing and painting of surfaces. Sculpture arises out of disaggregation.
So when we look at the Indian decimal system for noting numbers we first have to recognise that it is an aggregation, and then a special rhythmical form of aggregation. It is an aggregation of nested unities, with a gate + algorithm. The gatre+ algorithm controls the addition of the unities on a modulo basis. I could write the gate + as +modulo(10), meaning only add when this bracket = 10. There is one other thing and that is the power of the modulo, which is its place value power.
So its complete form is +modulo(10^n) where n is 0,1,2,3,4...
I can write the indian rhythm as
..........+modulo(10^3)+modulo(10^2) +modulo(10^1)+modulo(10^0)
which i can write as
........a*10^3+b*10^2+c*10^1+d*10^0 wnere ab,c,d are in modulo(10) or mod(9).
There are several ways of notating Napiers Logarithms but this one makes clear the previous discussions link to them and all calculation
n = a*log[((a-1)/a)^n ] where (a-1)/a is the base of the logarithm which is n/a. a is a factor to make the log into an integer.
As previously discussed the logarithm applies to all the values in between the integer value of the log. Therefore each base is portioned by the log method on a modulo arithmetic scheme: each whole log producing a proportional decrease by the base, so each partial log producing a proportional decrease somewhere in between each base.
Thus mod(base)*base^ logarithm is a way of representing the naperian notion of antilogarithm as Brigg expressed them in base 10.
Thus Brigg and Napier are really linking the indian rhythm to the dynamic motion of a hypotenuse of a right triangle in the sky, a hypotenuse attached to some moving planet or star, and thus linking its motion to the logarithms base sinπ/2.
Now the indians had already shown themselves masters of calculating sines for their astronomical use so it would appear that the sines were of great use and significance to astronomers of all cultures for calculation, but it was Napier who through dint of hard calculation turned them into a labour saving tool of great utility.
Prosthaparesis thus recommended the trig ratios as a useful source of exploration for quick reliable calculations, and Just Burgi made great use of it and some other methods which turned out to be correspondence relations between series
not logarithmsWe find that logarithms are a fundamental form of all computational structures since the indian rhythm was adopted.Logarithms are the basis of polynomials, the basis of our p-adic number system, the analysis of geometric and arithmetic series, the fundamental structure of our aggregation schemes, the link between the entities called roots of unity and the yoked units of shunaya, the essential relation between scale and proportion, an essential link in describing motion and relative motion and a describer of growth and gravitational constraints, and definitely more.
