Homeostasis and Complexity

Biomolecules such as RNA,DNA,amino acids etc, arose in a sea of interacting molecules in a  primordial soup. This was followed by compartmentalization to separate out the biomolecules from their environment. This resulted in homeostasis i.e. regulated exchange of matter between systems and surroundings.

According to wikipedia- "In biology, homeostasis is the state of steady internal physical and chemical conditions maintained by living systems.[1] This dynamic state of equilibrium is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range). Other variables include the pH of extracellular fluid, the concentrations of sodiumpotassium and calciumions, as well as that of the blood sugar level, and these need to be regulated despite changes in the environment, diet, or level of activity."
Why did complexity arise then ? To provide more and more regula…

Homeostasis

Yesterday I heard Dr.  Damasio on the mindscape podcast hosted by Prof. Sean Carroll.
https://www.preposterousuniverse.com/podcast/2019/04/29/episode-44-antonio-damasio-on-feelings-thoughts-and-the-evolution-of-humanity/

 It was a fascinating, insightful conversation.

The observation that "feelings" drive culture was new to me. From experience, I can say that feelings, along with thought do drive my choices.

Affect i.e. emotions and feelings play an important role in shaping societies. The hypothesis drawn  is that , homeostasis is a necessary pre-requisite to maintaining life , and homeostatic mechanisms result in feelings as adaptations to the environment.

Nervous systems could have evolved to regulate homeostasis. This is a strong argument from the evolutionary biology point of view, because the questions being asked today are-what are the environmental selection pressures that drive evolution.

Expansive mindset

Limited thinking resulting in human centeredness could be an anthropomorphic bias.

The only way out is to expand your horizon , by exposure to the unfamiliar.

Exposure to and exploration of unfamiliar environments, literature, art,  technologies, sport activities help in developing an expansive mindset.

An introspective, meditative mindset helps focus and channelize the distracted energy in the desired direction.

Irreversibility

Irreversibility-Does it arise due to emergence of properties via phase transition ? Is it a numbers game ?

Finding Balance-Personalized Precision medicine

Homeostasis maintenance is a fine line between order and chaos. One needs sufficient amount of order to perform a function in a focused manner. Simultaneously chaos is required for robustness , i.e. fine tuning inorder to adjust to the changing environment.
Personalized Precision  medicine is about finding this balance.
When homeostasis is disturbed in a living system, one has to diagnose the degree of disorder/chaos and concommitantly administer a drug at the required dosage and time intervals to restore the "balance" between order and disorder.
Swinging the pendulum in favour of order or disorder does not favour "life". Life is a fine balance between order and disorder.
AI or artificial intelligence in medicine can be used as a tool to swing the pendulum to either side, so it has to be used carefully.
A tool is not good or bad in itself . Its how one uses it.
In the nervous system it is the combined synchronous and asynchronous firing of neurons that results in …

Hypothesis of Perception-Phenomenal Mind arises from Self

Underlying Self-in 2D(Pure Consciousness), potentially  codes for vibrations of strings (packets of energy)/information of energy patterns in binary in fields---> Strings Vibrate in patterns of binary in fields giving rise to geometry in 3D ( Underlying Mind in 3D/No time or no cause,effect i.e. Consciousness)--->Resonance of newer strings--->Interactions between resonant/non-resonant strings---> Knots form giving rise to  particles (physics) that  interact  ---->Phase Transition from interacting particles---->Matter arises---->Constant/Background Material Brain Activity ---->Observation/Perception in time----->Phenomenal mind/mental activity in time(3D+1D=4D)/Emergent Consciousness.

Comment

Very interesting and Thank You for allowing to comment. I think the human sensory system and the machines it designs for observation are classical in one way and detect what they are designed to detect. Detection is interaction. And as RPFeynman put it "All mass/matter is interaction. So whatever interacts is detectable. If anything is beyond the detection system/ detection limit it ceases to exist for the detector. So one has to guess. My guess is possibilities and probabilities are infinite and the human sensory system and machines designed by it are observing a sliver of reality. May be Artificial intelligence linked to a probe/sensor with alternate/all possible arrangements of atom can detect different dimensions/many worlds. I think with present technology we are missing the woods for the trees. Consciousness or mind emerging from the brain (a certain arrangement of atoms) which directly observes or designs instruments for observation is only one method of detection.

Anthropomorphic bias

Thinking in hierarchies is an anthropomorphic bias.

 This thinking is in contrast to "integrative /systems thinking" which is inclusive, sees the whole instead of diving into parts and arranging in a hierarchy.
