Introduction :: Formalities

As long as the physical access to University si forbidden, we are going to meet in this Big Blue Button room.

You can get here by one single click from the address BAUMHAUS.DIGITAL

Modules : You can validate this course either as seminar of module Wissenschaften (VK), Theorie (KuM) or Studium Generale course.

Leistungsnachweis : Seed, plant or create an organic, digital or artistic tree and present the report about its growth.

You'll get two credits for Studium Generale (+positive note if You're exceptional); 3 credits for Wissenschaften (or 5 if You would write a 8-10 page essay).


Introduction :: digital ediquette

Please have Your camera turned off and microphone muted when You're not speaking.


Make sure that You use as stable & fast connection as possible (for example, connect through cable and not WLAN; if using WLAN, try to be in the same room as Your router etc.)


Before complaining that something does not work, try to solve a problem Yourself.


Be playful: start exploring functionalities like "chat" and "shared notes"


In case You feel really really lost, write a chat message to Paul, Felipe, Nikoloz or Dorothea.


 


Remember: friendship is everything

Einatmen 1 (BIO)
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" ?

Within each room, address the question "What is an organic tree ?" with words, pictures, songs, free associations.

(if You use the "shared whiteboard" functionality don't forget to make a screenshot before the break-out room closes)

You have 12 minutes. Afterwards, each group's speaker will be asked to do a 1 min report.

REMEMBER: There is no correct or incorrect answer.

Associatio :: Apple / Apfel
Please put into the "shared notes" (geteilte Notizen) any concept which You associate with the word "Apple".

Each student should write on one single line, please separate different concepts with the comma sign ",".

Lectio :: The Man Who Planted Trees
Let's do our first podcast. I look for 10 volunteers who would like to read the part of a beautiful short story "The Man Who Planted Trees" from Jean Giono.

Please put Your name in "geteilte Notizen" if You are interested and agree with having Your voice recorded.

What is a digital tree ?
You are going to be randomly associated into five "break-out" rooms. 

Within each room, address the question "What is a digital tree ?" / "What kind of digital trees do You know ?" with words, pictures, songs, free associations. 

(if You use the "shared whiteboard" functionality don't forget to make a screenshot before the break-out room closes) 

You have time until 10:40. Afterwards, each group's speaker will be asked to do a 1 min report. 

REMEMBER: There is no correct or incorrect answer.
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.

P.S. this binary tree will help You : https://kastalia.medienhaus.udk-berlin.de/7815

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.

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.

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

  • Break-out room, 15 minutes

  • Collaborative ASCII or whiteboard screenshots highly appreciated.

#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.

The core metaphor
"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 ?
