ZQ15.2

Latest issue 15:2
A. Digital drawings of plants

B. Steven Vogel on invention success vs failure:
– Is the device likely to work at a scale that is useful for humans?
– Can a version of the device be constructed by means that are practical for human technology?
– Might the device possibly offer some advantage in an application over what we currently use, or might it offer some entirely new and attractive capability? (compare existing market)
– Can nature’s version be improved upon either in fuctional effectiveness or in ease of manufacture by some alteration in the design such as using materials and components specific to human technology?”

C. Steven Vogel on why solar panels shouldn’t look like trees

D. Back issues are really great too:

IV. Grasshopper Examples:
Flying –
– Series to create freeze frame motion > slider bar
– Graph mapper for flight path
Kangaroo
– Points > Particles with mass and velocity
– Lines > Springs from Lines
– Meshes > Springs from Mesh, Wind for Mesh

C. Programming Architecture
hit Blog for video on Coding Evolution (genetic algorithms)
Milos Dimcic has created Rhino GH tools for working with rain, structurally optimized voronoi patterns and sun shadows. Site includes visually impressive projects and animations about the software. Dimcic worked for Knippers Helbig and then completed his Ph.D. with Jan Knippers in Stuttgart and Kai-Uwe Bletzinger at Munich.

D. Metaball Explanation by David Rutten, GH author

For the Ambitious: Manuel De Landa on Genetic Algorithms and Architecture

Poetic lecture presenting a concise contemporary approach to design. Explains an approach of using genetic algorithms “to tease out the morphogenetic (formal) potential from materials”, the beauty of variety so that a specific instance can be fitted to circumstances. A world of flows and a network of local conditions rather than fixed euclidean frameworks.

HOMEWORK

A. ** DOWNLOAD and Install Kangaroo Physics 2.02 and 0.099 from http://FOOD4rhino.com You must uninstall any old versions to make it work.

B. Work on Analytic Case Study for Final Project:

  1. Clearly define a problem in a specific location.
  2. Find an organism that thrives in that location.
  3. Identify how the organism thrives:  Draw key aspects of the internal organization, membrane, external sensors and reactions to environmental stimuli, etc.
  4. DIAGRAM key principles :  abstract the underlying ideas.

C. Read Turner’s Bones, Vogel’s Cat’s Paws and Catapults (Ch.3-5) from the Course Disk : easy and fun.

II. Homework (10:20)

III. Genetics (10:40)

Evolutionary Development Master Hox genes turn on genes that create parts of the body. Chicken Teeth can be created when latent extinct genes are accidently activated:

Fractals and Recursion

III.  Marziah Rajabzadeh and Modi Marizad of ZAAD Studio (11:00)
RECOMMENDED:

Prof. Robert Sapolsky on Emergence and Complexity explains mathmatics in the context of biological phenomena: how simple mechanisms can create complexity.

John Frazier’s Evolutionary Architecture

Physical computing: interaction creates electronic connections between modules > Skylar Tibbett’s project to embed intelligence

Concept of creating many unexpected variations

Genetic algorithms create rules for creating the next generation and then making a selection of survivors. (Natural articulated rules vs. Artificial selection through intuition).
Convergent vs. Divergent solutions

The Development system reads the environment and the genes to create results which provides feedback to both. The Genetic algorithm determines how the child variants are created from the parents and how results are sorted.
It has to be a consistent system generating reliable results

10:30 Pinup homework / review solar skin approaches

10:50 Introduce New Assignment: GROWTH – Capturing Change

11:00 SYSTEMS THINKING
1) What is a system?

(from Daniel Kim’s Leverage Network:  https://www.leveragenetworks.com/learn/systems-thinking)

  • Purpose
  • Parts contribute to the purpose
  • Organization and roles make the system work
  • Stability through feedback

See Donella Meadow’s book Thinking in Systems: a Primer (e-book available through UO Libraries)

2) Thermostat as Balancing Loop

3) Dieter’s dilemma – Oscillation
Reading Causal Loops: https://www.leveragenetworks.com/reading-causal-loops

4) Are these systems?

  • a piece of paper
  • a car
  • a stop sign
  • a bowl of fruit (see Daniel Kim Reading)

5) Reinforcing Systems: Positive comments, Negative snarks

6)Cybernetic Correcting Systems: https://vimeo.com/41776276

7) Natural Nitrogen Cycle: closed loop
Artificial Nitogen Cycle: reinforcement of fertilizer use > eutrefacation

8) Unintended consequences: Kangaroo vs. Sheep

9) ACTIVITY: Dryer example: What are the hidden costs?
