- complex systems ~ [[non linear systems]]
-
[[lecture 4]] [[the systems view of evolution]]
- [[summary]] https://spring.capracourse.net/wp-content/uploads/2021/03/Lecture-4-Summary.pdf
- [[prebiotic evolution]]
-
[[lipid walls]] acted as proto membranes, formed [[bubbles]]
- within simple bubbles that tended to let some compounds selectively in and keep them in, those compounds collisioned and interacted much more often than without
-
yields [[network chemistry]], highly [[non linear]]
- ()[[non linear dynamics]], [[complexity theory]] figures prominently.)
- competition for nutrients yielded [[evolutionary pressure]]
-
[[universal ancestor]] is thought to have come into existence around ~3.5B years ago
- colonized essentially our whole environment, making future life possible
-
#push [[the systems view of evolution]]
- [[prebiotic evolution]] plus new understanding of [[biological evolution]]
- rather than seeing evolution as the result of random mutations, the central focus is on the creativity unfolding of life in forms of increasing complexity of increasing diversity
- the [[dynamics of life's creativity]]
-
#push [[history of evolutionary thought]]
-
#push [[charles darwin]]
-
based his theory on two core ideas:
- [[chance variation]] -> [[random mutation]]
- [[natural selection]]
- all living organisms are related by common ancestry
- [[beagle]]
-
Darwin knew not of a remedy to a problem of his theory: he thought heredity worked so that offspring received 50% of the traits of each ancestor, their offspring 25%, theirs 12.5%, etc.
- Darwin saw this as a flaw as it showed that positive traits would disappear very quickly after arising and being selected by chance.
- [[Mendel]] of course discovered the units of heredity, [[genes]].
- [[Mendel]] wrote to [[Darwin]] ()!), and allegedly Darwin didn't read the letter because it was in German and had too much math on it (!).
-
based his theory on two core ideas:
- [[radical shift]] in biological thought: from [[being]] to [[becoming]] (a shift towards change)
- [[holistic view]]
-
#push [[neodarwinism]]
- evolutionary variations result from random mutations, being random genetic changes, followed by natural selection.
-
#push [[systems view of evolution]]
-
recognizes three major avenues of evolution:
-
[[random mutations]] == [[genetic mutations]]
- most mutations are harmful, few lead to positive variations
- note that one bacteria can become [[billions]] in just one day
-
[[horizontal genetic transfer]] == [[gene trading]]
-
[[bacteria]] freely trade genes, swap genes with each other
- global trading of genes (!)
- [[lynn margulis]]
- some [[microbiologists]] argue that [[bacteria]] should not be categorized into [[species]]
- during the first [[2 billion]] years of evolution, only bacteria were around
- [[bacteria]] bootstrapped it all, established the global system
-
#push [[bacteria]] also invented:
- [[fermentation]]
- [[photosynthesis]]
- [[nitrogen fixation]]
- [[rapid motion]]
- [[respiration]] (!)
-
[[bacteria]] freely trade genes, swap genes with each other
-
[[symbiogenesis]]
- [[evolution through symbiosis]]
-
[[lynn margulis]] as well
- hypothesis: long term [[symbiosis]] involving [[bacteria]] and other [[microorganisms]] as hosts/guests led to complex life
-
[[acquiring genomes]]
- compares organisms to [[corporations]]
-
[[random mutations]] == [[genetic mutations]]
- all three of the previous produce changes that need to be integrated into the physical and chemical environment; if the integration of new genetic information doesn't work, the organism can't survive -> there's natural selection
- [[epigenetic network]]
- real life example: in human life you make plans (you have a plan for your night), plans need to adapt to random occurrences (people you run into; other events out of your sphere of control). evolution works the same way.

[[lecture 5]] [[mind and consciousness]]
- [[summary]] https://spring.capracourse.net/wp-content/uploads/2021/03/Lecture-5-Summary.pdf
- [[gregory bateson]]
-
#push [[santiago theory]]
- [[humberto maturana]]
- [[francisco varela]]
-
a new conception of the nature of [[mind]] and [[consciousness]] is an implication of the [[systemic understanding of life]]
-
it goes beyond the [[cartesian division]].
-
[[renΓ© descartes]] based his thought on a fundamental division between [[res cogitans]] (the thinking mind) and [[res extensa]] (matter, the extensive thing)
- [[mind]] as an intangible entity poses the question of how it interacts with matter
-
[[renΓ© descartes]] based his thought on a fundamental division between [[res cogitans]] (the thinking mind) and [[res extensa]] (matter, the extensive thing)
-
mind and consciousness are not [[things]], they are [[processes]]
- [[gregory bateson]] [[mental process]]
- independently [[humberto maturana]] had similar ideas w.r.t. [[cognition]]
-
[[francisco varela]] worked with him and developed his insights into a theory known as [[santiago theory of cognition]]
- [[cognitive science]] is a [[transdisciplinary approach]]
- the process of knowing and the process of life are one and the same
- [[cognition]] is the activity involved in the self generation and self perpetuation of [[living networks]]
- the self organizing activity of a living system at all levels is [[mental activity]]
- the interactions of a living organism with its environment are [[cognitive interactions]]
- life and cognition are inseparably connected at all levels of life
- cognitive activity is [[immanent]] in life
-
[[cognition]] does not require a [[brain]]/nervous system
- plants, bacteria which don't have nervous systems are all constantly involved in [[cognitive activities]] (as they perceive, react)
-
it goes beyond the [[cartesian division]].

-
[[lecture 12]] [[systemic solutions]]
-
[[energy crisis]]
- many possible solutions
-
two false solutions, non-systemic
- [[clean coal]] is essentially an advertising slogan for new, unproven techniques for carbon capture
-
hope that [[nuclear power]] could replace coal, but the risks were underexplored.
-
in the book [[fritjof capra]] summarizes [[seven inconvenient truths]] about [[nuclear power]]
- creates significant greenhouse gases
- uranium supplies are very limited
- construction time of plants is too long
- waste storage problem remains unsolved
- nuclear power and nuclear weapons are inextricably linked
- new generation reactors have the same problems and are too late
- nuclera power is not viable commercially

#push [[plan b]] by lester brown
- shows strategies building on existing technology, working examples from around the world
- eradicating [[poverty]] and stabilizing [[population]]
- stabilizing [[climate]]
- restoring the earth's [[ecosystems]]
-
[[reinventing fire]] by [[amory lovins]]
- focus is narrower than brown's
- "to create a clear and practical vision of a fossil fuel free future backed up by quant analsys and to map out a path towards that future"
- massive savings in energy and cost
- hope is that business could get behind the cost savingssss
-
[[the third industrial revolution]] by [[jeremy rifkin]]
-
renewable energy sources
- hidrogen
- [[fossil fuel free future]]] (~ [[ffff]])
- electric vehicles
- smart grids
- government agencies focus
- [[widely distributed]] grids enabled by the [[internet]]
-
renewable energy sources
-
[[global food crisis]]
- similar to and interlinked with the [[energy crisis]]
-
two basic types of [[food systems]]
- industrial production: energy intensive, centralized, [[fossil fuel]] based
- traditional practices: distributed, organic
-
[[chemical agriculture]] was hailed as a new era, and it was actually seen as a [[green revolution]], but...
- massive use of fertilizers/pesticides changed the whole fabric of agriculture
- single crop monoculture took over, led to soil depletion and escalating use of pesticides
- high energy use resulted in great concentration in very large farms
-
[[gmos]]
- long session on this and genetic engineering in the book
- the main objective in genetic engineering seems to have been to increase the sales of chemicals :(
-
#push [[agroecology]]
- [[organic farming]], [[permaculture]], [[sustainable argriculture]]
- variety of crops, rotated
- instead of chemical fertilizers, a focus on manure and organic material from previous crops
- it embodies ecological principles which have been tested by [[evolution]]
- soil is actually alive: there are billions of organisms in every [[cm3]]
- [[diversification]] and [[intercropping]]
- [[agroforestry]]
- "[[agroecology]] (is/might be) able to raise agricultural productivity in ways that are economically viable, ecologically sound and socially uplifting"
- soil that is organically managed is a carbon store (as it's full of life)
- [[carbon sequestration]] in soil and plants is currently the only known and proven technology to draw down [[co2]] from the atmostphere and in the long run stabilize climate
-
#push [[ecodesign]]
-
[[david orr]]
- "[[ecological design]] is the careful meshing of our [[human purposes]] with the larger [[patterns]] and [[flows]] of the natural world"
- eco design principles reflect those that are found in nature to support life
- "what can we learn from nature" (instead of what can we extract from it)
- some examples from two areas
-
[[organic cycles]]
- coffee production + mushroom production + livestock + ...
-
[[technical cycles]]
- between manufacturers and consumers
- (maybe related to [[repair movement]]?)
- people want services, not products
- the manufacturer could "own" devices, be responsible to recycle all components at the end of life of a device
-
urban [[ecodesign]]
- ~60 cities have adopted the [[curitiba]] model
- modern [[car free]] environments
- [[urban villages]]
- [[high density]] structures combined with ample [[green spaces]]
-
[[david orr]]
- [[system solutions]] in this lecture seem to provide ample evidence that we have the tools to build a [[sustainable future]] -- what we need is [[political will]] and [[leadership]]
-
[[energy crisis]]
-
[[conclusion]]
- [[leadership]] means [[facilitating the emergence of novelty]]
-
often asked: "will there be enough time to save human civilization", "can we have hope for the future"?
-
the most inspiring answer to this comes from [[vΓ‘clav havel]]
- a meditation on [[hope]] itself
- written while imprisoned under the [[soviet regime]]
- "The kind of [[hope]] that I often think about I understand above all as a state of mind, not a state of the world. Either we have hope within us or we don't. It is a dimension of the [[soul]] and it's not essentially dependent on some particular observation of the world or estimate of the situation. Hope is not the conviction that something will turn out well, but the certainty that something [[makes sense]] regardless of how it will turn out."
