SoSe 2024 / AE54 - Computational Beauty of Plants
SoSe 2026 / AE56 - Über Knoten, Kurven und Kreise  

Einatmen 1 :: Bildung Biodigitale

Bildung BioDigitale = humanism + digitalisation + ecology

Goal 1: Establish a bridge between organic (carbon-governed) and digital (silicon-governed) realms

Goal 0: Survive

Method: Education

The Core Metaphor(s) :: Subjective variant

Observer observes a certain similarity-of-forms, a certain "morphism", between organic entities known as "trees" and structures of the digital realm.

Observer observes a certain similarity-of-forms, a certain "morphism", between organic processes known as "germination, differentiation, growth and decay" and processes taking place in the informatic realm.

Einatmen 1 :: Avocado

Last winter/early spring bought a Kiste of avocados for 3 euros at Türkisches Markt at Görschstrasse / Yorckstrasse.


Germination most probably took place in compost.


Developped wonderfully until cca september, survived a Blatt-läuse attack, managed to adapt to the local soil.


Started losing leaves in autumn.


Survived first Berlin winter.

Ausatmen 1 (BIO) :: Discussion

Ask, criticize, go for it !

Einatmen 2 (DIGITAL) :: Formal Systems

WIKI :: A formal system is used for inferring theorems from axioms according to a set of rules. Each formal system uses primitive symbols (which collectively form an alphabet) to finitely construct a formal language from a set of axiomst through inferential rules of formationThe system thus consists of valid formulas built up through finite combinations of the primitive symbols—combinations that are formed from the axioms in accordance with the stated rules.

Ausatmen 2 (DIGITAL) :: Break-out room test

You are now going to be randomly divided into 3 break-out rooms.

Please try to discuss the question "What is a formal system ?" and why does Douglas Hofstadter represents it as a "tree" in his marvelous book "Godel, Escher, Bach" ?

Taxonomies

Taxonomy is the practice and science of categorization based on discrete sets. The word is also used as a count noun: a taxonomy, or taxonomic scheme, is a particular categorisation. The word finds its roots in the Greek language τάξις, taxis (meaning 'order', 'arrangement') and νόμος, nomos ('law' or 'science'). Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. (https://en.wikipedia.org/wiki/Taxonomy_(general) )

Today's course

Binary trees

From a graph theory perspective, binary (and K-ary) trees as defined here are actually arborescences. A binary tree may thus be also called a bifurcating arborescence—a term which appears in some very old programming books, before the modern computer science terminology prevailed. It is also possible to interpret a binary tree as an undirected, rather than a directed graph, in which case a binary tree is an orderedrooted tree. Some authors use rooted binary tree instead of binary tree to emphasize the fact that the tree is rooted, but as defined above, a binary tree is always rooted. A binary tree is a special case of an ordered K-ary tree, where k is 2. ( https://en.wikipedia.org/wiki/Binary_tree )

Exercicio :: Binary tree 1-32

You will be divided into break-out rooms in which You will play the "number guessing game". Game goes like this:

one person chooses, in his|her mind only a number N between 0 and 31


other start at node 16 and ask "is N smaller than 16?" ... if the answer is "yes", You will take the upper/left road leading to number 8 ... if the answer is "no", You will take the lower/right road leading to number 24


now You ask, "is N smaller than 8?" (or 24)...again, if the answer is "yes", You take the upper/left road (leading You to 4, resp. 20), in other case You take the lower/right road (leading You to 12, resp. 28)


You repeat two more times until You reach the leaves of the tree....if N is odd, the leaf node where You finished is the number N


(if number N is even, than it is one of those numbers which You traversed on Your path, e.g. 16,24,20 or 22 if You ended up at leaf 23)


then another person invents the number and others guess.

Birch :: Birke :: Betula Pendula :: *bʰerHǵs :: The Luminant

A species of tree in the family Betulaceae (ord. Fagales, clade Rosids, kingdom Plantae). The silver birch typically reaches 15 to 25 m tall (exceptionally up to 31 m) with a slender trunk usually under 40 cm diameter. The bark on the trunk and branches is golden-brown at first, but later this turns to white as a result of papery tissue developing on the surface and peeling off in flakes, in a similar manner to the closely related paper birch (B. papyrifera). The bark remains smooth until the tree gets quite large, but in older trees, the bark thickens, becoming irregular, dark, and rugged. The leaves have short, slender stalks and are 3 to 7 cm long, triangular with broad, untoothed, wedge-shaped bases, slender pointed tips, and coarsely double-toothed, serrated margins.

Birchjuice / Birkensaft

in March / April


choose a tree which has cca 20-30 cm diameter at 1m height


at 1m height, drill a cca 2cm-5cm hole with 0.5 cm diameter


insert a drinking straw or a glass tube


collect max 2-3 liters per tree


enclose the drill hole with earth/soil and ash (otherwise the tree could "bleed to death")


for a chosen tree, do not apply more often than once in 2 years

What a Birch provides ...

...shoes, containers, boats, mats, roofs, brooms, craddles for newborn, tar, oil, birch flour, torches, paper / postcards, fire in rainy times, chewing gums ...

... information about beginning of the spring, substrate for most robust trees,  shamanic drums ... 
 
...Flavonoids, Saponines, Salicylate, Vitamine C, Ascorbic acids, Betulin acid (good against skin cancer), Xylit ...

Birch provides four good things: she illuminates (used for torches); she strangles cries (birch tar used for creeking wheels); she heals the sick and she purifies (birch canes in sauna).

Birkenruteerziehungsngsinstrument

Die Birke ist auch heut zu Tag in großer Ehr, dieweil sie die böse uns ungehorsame Kinder und Jugend straffet. Daher man dann in Teutschen Reimen sagen: O Du gute Bircken Ruth, Du machst die ungehorsamen Kinder gut ! (Lonicerus, 1679)

Beith

Beith is the Irish name of the first letter (Irish "letter": sing.fid, pl.feda) of the Ogham alphabet, meaning "birch". In Old Irish, the letter name was Beithe, which is related to Welsh bedw(en), Breton bezv(enn), and Latin betula. Its Proto-Indo-European root was *gʷet- 'resin, gum'. Its phonetic value is


This moreover is the first thing that was written by Ogham, i.e. (the birch) b was written, and to convey a warning to Lug son of Ethliu it was written respecting his wife lest she should be carried away from him into faeryland, to wit, seven b’s in one switch of birch: Thy wife will be seven times carried away from thee into faeryland or into another country, unless birch guard her. On that account, moreover, b, birch, takes precedence, for it is in birch that Ogham was first written. (from Auraicept na n-Éces, "the Scholar's Primer")

A guessing game


  • One person chooses some well known animal or plant.

  • The others try to guess it, they can only ask Yes / No questions. (e.g.  Do You live in a forest ? Are You rooted ? Do You have four legs ? Do You fly ? etc.)

  • The one who guesses is the one who chooses the animal/plant entity for the next round.

  • How many rounds can You do in 10 minutes ?

Decision Trees

Decision Trees in Machine Learning

Example: The Senster (1970)

Questio: What do organic and digital / informatic / numeric trees have in common ?


  • Break-out room, 15 minutes

  • Collaborative ASCII or whiteboard screenshots highly appreciated.

Answer 4 :: "sequential"

Tree embodies development in time & has "archival" function.

Answer 3 :: "functional"

Functional morphisms (upwards & downwards "flow", "bifurcations", "supply" )

Answer 2 :: "structural"

Structural morphisms (roots, branches etc.)

Answer 1 :: "conceptual"

Both organic and digital trees are human concepts (results of activity of analytical Mind).

Answer0 :: "partitioning"

Both organic and digital trees divide "the space" into partitions.

#root ( http://www.linfo.org/root.html )

root is the user name or account that by default has access to all commands and files on a Linux or other Unix-like operating system. It is also referred to as the root account, root user and the superuser.

Root privileges
are the powers that the root account has on the system. The root account is the most privileged on the system and has absolute power over it (i.e., complete access to all files and commands). Among root's powers are the ability to modify the system in any way desired and to grant and revoke access permissions (i.e., the ability to read, modify and execute specific files and directories) for other users, including any of those that are by default reserved for root.


The word root also has several additional, related meanings when used as part of other terms, and thus it can be a source of confusion to people new to Unix-like systems.


One of these is the root directory, which is the top level directory on a system. That is, it is the directory in which all other directories, including their subdirectories, and files reside. The root directory is designated by a forward slash ( / ).


Another is /root (pronounced slash root), which is the root user's home directory. A home directory is the primary repository of a user's files, including that user's configuration files, and it is usually the directory in which a user finds itself when it logs into a system. /root is a subdirectory of the root directory, as indicated by the forward slash that begins its name, and should not to be confused with that directory. Home directories for users other than root are by default created in the /home directory, which is another standard subdirectory of the root directory.

Lectio :: Neal Stephenson :: In the beginning was a command line

under Unix thehighest level–the root–of the filesystem is always designated with the single character"/" and it always contains the same set of top-level directories:

/usr/etc/var/bin/proc/boot/home/root/sbin/dev/lib/tmp

and each of these directories typically has its own distinct structure of subdirectories.Note the obsessive use of abbreviations and avoidance of capital letters; this is a systeminvented by people to whom repetitive stress disorder is what black lung is to miners.Long names get worn down to three-letter nubbins, like stones smoothed by a river.

Formalia

The last session

Last session of the course 'Of organic and digital trees' is going to start @10:00 AM near entrance to greenhouses of Botanischen Volkspark Blankenfelde-Pankow.

Bring Your trees & texts & works along !

Formalia 1 :: Rundgang

Do we want to participate ?

Formalia 2 :: SG Validation

Studium Generale students who will not validate more than 80% of attendance will be asked to write an essay. There are two topics You may potentially choose:

  • What role do trees and forests play in Life and Work of Ursula leGuin ?

  • Is the "core metaphor" false or true ? If true, is it true subjectively or objectively ?

The core metaphor

The Core Metaphor(s) :: Subjective variant

Observer observes a certain similarity-of-forms, a certain "morphism", between organic entities known as "trees" and structures of the digital realm.

Observer observes a certain similarity-of-forms, a certain "morphism", between organic processes known as "germination, differentiation, growth and decay" and processes taking place in the informatic realm.

The Core Metaphor(s) :: Objective variant

There exists a certain similarity-of-forms, a certain "morphism", between organic entities known as "trees" and structures of the digital realm.

There exists a certain similarity-of-forms, a certain "morphism", between organic processes known as "germination, differentiation, growth and decay" and processes taking place in the informatic realm.

"The Core Metaphor is false"

You will be divided into break-out rooms.

Please try to provide as much arguments as possible for the statement: organic and digital trees are distinct types of entities which have very little (resp. nothing) to do with each other.


In case You encounter difficulties, address the question: What distinguishes "organic" from "digital" trees ? How are these types of entities (concepts?) different from each other ?


You have 15 minutes. Frohe philosophieren !

(c.f. also Prolegomena Paedagogica, p. 114-115)

L&C :: Formal grammars

In formal language theory, a grammar (when the context is not given, often called a formal grammar for clarity) describes how to form strings from a language's alphabet that are valid according to the language's syntax. A grammar does not describe the meaning of the strings or what can be done with them in whatever context—only their form. A formal grammar is defined as a set of production rules for strings in a formal language.

A formal grammar is a set of rules for rewriting strings, along with a "start symbol" from which rewriting starts. Therefore, a grammar is usually thought of as a language generator. However, it can also sometimes be used as the basis for a "recognizer"...

L&C :: Formal languages as trees

L&C :: Parse trees

Note of warning

"Strictly formalist, transformationalist approach had failed to furnish a complete, consistent elegant framework for the study of natural languages but
significantly facilitated construction and further development of artificial and programming languages."

(Prolegomena, p. 120)

Simply stated: formal languages are about games with symbols but not about communication or exchange

Room 3

(Alex, emeka ene, Filipe, Ole, Paul Seidler, Robert Schnüll)

volatiles for inter and intra tree  and 
interspecies communication
does communication imply intention?
mycelium networks
through sound? through light?

Room 2

smell emissions (like resin, for example)
they communicate with their mizells, via roots
chemicals in water they transport
pollen, 
insect messenger
sounds ( of sap of the trees ,...)
perhaps with their leafs 
colours, e.g. of leaves, bark, blossoms
Mykorriza as communication leader

Room 1

(Adam Behlen, Ana Obara Takano, Karla und Cara, Linda Elsner, Maria Ladopoulos, Tanja Al Kayyali)

underneath the earth, roots and flow of nutrients
 
leaves - indicator for health of the tree
 
pollination via insects 
diseases spread across trees via insects/animals
fruits / seeds 
 
circle of life - dead tree parts are nutrients / fertilizer for next growing tree 🌲 
 
filtration systems for humans/animals - clean air 
 
intertwining of branches, growing together
 
communicating survival of the fittest, dense forrest situations, access to sunlight
 
touching through force of wind (crown)

Session 5 :: The Form of a Tree










Session 5 :: 24.6.2020 / AE500624 :: 

Form of the Multiverse is the Form of a Tree

The Form ...

 

... of a Tree

The form of a tree is: Fractal.

a fractal

A fractal is an entity that displays self-similarity.

examples of fractals

Break-out room (10 minutes) :: What kind of fractals do You know ?

Fractal dimension

In mathematics, more specifically in fractal geometry, a fractal dimension is a ratio providing a statistical index of complexity comparing how detail in a pattern (strictly speaking, a fractal pattern) changes with the scale at which it is measured. It has also been characterized as a measure of the space-filling capacity of a pattern that tells how a fractal scales differently from the space it is embedded in; a fractal dimension does not have to be an integer.

The form of a multiverse is: Tree.

Universe 1 :: Stephenson's Arbre

Universe 2 :: Simmons Hyperion & God's Grove

God’s Grove was as it always was—perfumed by the scent of a million million trees, silent except for the soft sounds of leaf rustle and wind, colored in halftones and pastels, the sunset igniting the literal rooftop of the world as an ocean of treetops caught the light, each leaf shimmering to the breeze, glittering with dew and morning showers as the breeze rose and carried the smell of rain and wet vegetation to Gladstone on her platform high above the world still sunk in sleep and darkness half a kilometer below.

A Templar approached, saw the glint of Gladstone’s access bracelet as she moved her hand, and withdrew, a tall, robed figure blending back into the maze of foliage and vines.

The Templars were one of the trickiest variables in Gladstone’s game. Their sacrifice of their treeship Yggdrasill was unique, unprecedented, inexplicable, and worrisome. Of all her potential allies in the war to come, none were more necessary and inscrutable than the Templars. Dedicated to life and devoted to the Muir, the Brotherhood of the Tree was a small but potent force in the Web—a token of ecological awareness in a society devoted to self-destruction and waste but unwilling to acknowledge its indulgent ways.

Where was Het Masteen? Why had he left the Möbius cube with the other pilgrims?

Gladstone watched the sun rise. The sky filled with orphan montgolfiers saved from the slaughter on Whirl, their many-hued bodies floating skyward like so many Portuguese men-o-war. Radiant gossamers spread membrane-thin solar wings to collect the sunlight. A flock of ravens broke cover and spiraled skyward, their cries providing harsh counterpoint to the soft breeze and sibilant rush of rain coming toward Gladstone from the west. The insistent sound of raindrops on leaves reminded her of her own home in the deltas of Patawpha, of the Hundred Day Monsoon which sent her and her brothers out into the fens hunting for toad flyers, bendits, and Spanish moss serpents to bring to school in a jar.

Gladstone realized for the hundred thousandth time that there was still time to stop things. All-out war was not inevitable at this point. The Ousters had not counterattacked yet in a way the Hegemony could not ignore. The Shrike was not free. Not yet.

All she had to do to save a hundred billion lives was return to the Senate floor, reveal three decades of deception and duplicity, reveal her fears and uncertainties …

No. It would go as planned until it went beyond planning. Into the unforeseen. Into the wild waters of chaos where even the TechnoCore predictors, those who saw everything, would be blind.

Gladstone walked the platforms, towers, ramps, and swinging bridges of the Templar tree city. Arboreals from a score of worlds and ARNied chimps scolded her and fled, swinging gracefully from flimsy vines three hundred meters above the forest floor. From areas closed to tourists and privileged visitors, Gladstone caught the scent of incense and clearly heard the Gregorian-like chants of the Templar sunrise service. Beneath her, the lower levels were coming alive with light and movement. The brief showers had passed over, and Gladstone returned to the upper levels, rejoicing in the view, crossing a sixty-meter wooden suspension bridge connecting her tree to one even larger, where half a dozen of the great hot air balloons—the only air transport the Templars allowed on God’s Grove—hung tethered and seemingly impatient to be away, their passenger nacelles swinging like heavy brown eggs, the skins of the balloons lovingly dyed in the patterns of living things—montgolfiers, Monarch butterflies, Thomas hawks, radiant gossamers, the now-extinct zeplens, sky squids, moon moths, eagles—so revered in legend that they had never been, retrieved or ARNied—and more.

All this could be destroyed if I continue. Will be destroyed.

PrePHD Research 2

while the last presentation was mainly about reseach into practical computational systems (turing machines etc) ,this presentation focuses on theorethical references and research towards numbersystems / and compuational systems and cognitive regonitions. Meaning looking into Questions of how compuational numbersystems arrived historical and questions regarding the epistemology of numbers (also with a focus on Bildung)
