All Biological life on earth is possible because of a discrete digital mechanism of preservation and replication.

 The mechanism of signaling between the superorganism we know of as bacteria and its ongoing war against viruses is through a digital mechanism.
The source of innovation in biology is in this milieu of microbiome and viromes that are ubiquitous in every complex multicellular organism on earth. Humans are walking ecologies and cannot survive stripped of these ecologies.
We can picture this as a cloud of digital interaction that surrounds all of us.
The cells of multicellular creatures however do not communicate in the same way as bacteria. The DNA of mammals are sequestered from daily activity so as to prevent wear and tear.
The lifespan of mammals are related to their metabolism. The faster a mammal's heart beats the less time it has to live. A multicellular creature degrades like an analog system with each iteration error is accumulated.
Death is inevitable for multicellular creatures because our bodies have similar dynamics as non-linear systems found in chaos theory. The attractors that lead to our existence can lead to chaos and thus death.
Fortunately, evolution has gifted us with some of the digital mechanisms that bacteria have. The immune system is digital in nature. The same system that protects us from bacteria and viruses is also the same system that corrects for errors in our bodies.
At higher scales, evolution creates species that are more analog. But there is a constant tension between the drive to become analog and the need for preservation and replication.
All biological creatures balance these opposing forces by leveraging what is known as code duality. Every system has both an analog part that meets with the world and a digital part that preserves itself against the world.
In biology, the stuff that interprets the digital code of RNA are analog devices. More specifically, mechanical and electrical nano-machines.
The molecular machinery that converts energy into motion and energy into sensing are a consequence of biological innovation happening at bacteria and viral level.
But what meets the reality of physics and chemistry are analog machines. Living things require analog machinery to interpret and act within the world. The language of reality at higher scales is an analog language.
But to scale in size any organism requires digital mechanisms. Therefore this code duality must exist at many scales in a complex organism.
A common idea about the brain is that it is a dynamical system. A dynamical system is unlike a digital system like a computer. Brains have evolved to make sense of and move within their environments. They can only do so if they meet with the analog environment.
This idea however is an incomplete picture in the framing of code duality. The brain should have a digital component as predicted by this hypothesis of code duality. That digital component shares the same origin as our immune system.
Our immune system has the fascinating capability of recalling all the pathogens that have attempted to infect the body. What is the mechanism of this incredible memory system?
I've mentioned earlier that the human cognitive system consists of 3 'brains'. The nervous system, the endocrine system and the immune system. It's a very different triune brain that people conventionally think of.
The difference with biology and things that we design is that the latter has a designer that organizes things. So in a computer, the common currency is electrons. In biology, there is no common currency but a bureaucracy of transactions between different incompatible coins.
RNA has a surprisingly common currency (i.e. nucleotides). It is universal across earth originating living things. The power of digital systems come from a multitude of possible combinations. This only comes from standardization that leads to compatibility.
So evolution despite not having a designer with a mind, it has arrived at a strategy that acts like it has a mind!

It is astonishing that most of cognitive science ignores an obvious reality. That there are two kinds of humans.

Tomasello has a very credible hypothesis that what distinguishes humans from the great apes is the inclination towards shared intentional behavior. What is innate is the disposition and like personalities, it is what defines our cognition as we grow.

If cognitive preference is so critical in cognitive development then why is it that we seem to have completely ignored the difference in cognitive preferences between men and women?

Humans are that species of primates that wandered out into the savannah. The savannah is different enough from a dense jungle to exert the evolutionary pressures that encourage the development of planning and forecasting skills.

Furthermore, human infants required a disproportional amount of effort to rear. This meant the specialization of roles between women who were responsible for rearing offspring and men who were responsible for bringing home the bacon. Failure in either implied death.

Interesting to realize that the living things that lay the foundation of the biosphere are extremely robust as compared to the humans that are destroying the biosphere.

Seed can remain dry and dormant for ages only to reborn when provided the proper nutrients. In contrast, most animals require a continual living vessel to reconstruct itself from its DNA.

Evolution appears to constantly perform tradeoffs between robust organisms and organisms that are adaptable. Co-evolution makes possible the development of complex species as a consequence of robust organisms.

We exist as a consequence of the multitude of less complex individuals that make up our biosphere. We are in fact symbionts that are in constant cooperation with our microbiome. Absent our individual ecologies leads to death.

We are inseparable from our microbiome, we are inseparable from our societies, and we are inseparable from our biosphere. The biggest lie we are told is that as individuals, we are independent of our world.

Chess may be a good analogy for explaining the difference between a descriptive model of reality and a generative model of reality.

A descriptive model of chess will describe the rules (i.e. initial setup, allowed moves, points per piece, objectives). This tells you how a chessboard might evolve and also narrows the combinations of realistic chess positions.

In contrast, a generative model involves the actual gameplay between competing players that follow the rules. It generates new styles and patterns. It establishes new strategies and tactics. It generates new openings, middle gameplay, and end game tactics.

A generative model is an evolutionary model that leads to emergent behavior. As a consequence, a master of chess is able to recall the layout of chess positions in a real game in an instant, yet is unable to remember pieces placed in random positions.

That is because causality is present in the movements of pieces in a chessboard. An intuitive system like the human mind is able to capture that causality as a means to understanding and recall.

Conscious and conscience are two words that share the same origin but mean two different things. The bias against explanations of consciousness comes from the conflation of these two words.

In addition, the question of free will is also adjacent to the notion of both consciousness and conscience. The ideas of consciousness, conscience, and free will serve as the foundation of justice in our civilization. (care to add another?)

So when we see people fail to condemn an act that is morally repugnant, we wonder if they have a conscience. But we don't wonder if they are conscious. When we incarcerate a person, we ask if they had "free will" but we inquire if they were 'conscious' during the crime.

The presence of consciousness and free will imply sentience. Which is the same as conscious and sounds just like a conscience. Our biases have muddled all the words together to likely mean the same thing.

The words that we use today continue to evolve. The same word can have a different meaning in the past. The word empathy is a recent word invented in the early 1900s. Originally it meant to place oneself from the viewpoint of a thing. Today we don't use it in this way.

We wake up each day with the same attention budget as everyone else. This is the one thing all humans equally share.

Spending that attention budget by doing this is what gives meaning to our lives.

It's is only through doing that we learn. It is only through learning that we find meaning.

Yet many of us waste attention budget exclusively on consumption. Seeking the random dopamine hits that tickle our curiosity. Yet we seek only the convenient things to do.

Activities that are convenient, that takes little effort don't consume a lot of attention. But enough of these small distractions will. But unfortunately, there's little learning taking place.

A Thread about Famous Armenian Inventors and what we have contributed to the world. So the next time someone wants to say we are unimportant, you can rest easy knowing Armenians have contributed some of the greatest inventions to mankind. Here is a handful but there's more.


Raymond Damadian: Armenian-American Physician and inventor of the first MRI machine. MRI is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body. Raymond created the first MRI in 1977.


Artem Mikoyan: One of the most famous engineers in aviation. Mikoyan along with Gurevich created one of the most famous Jet lines in history, the MiG. MiG jets directly competed with American Lockheed Martin F Series planes and were among the first to surpass the speed of sound.


Hovannes Adamian: Most notably laid the foundations of color television with his Tri-Color Principle. His work would go on to become the framework that is used to create Color-TV that we see today. He is recognized as one of the founders of color television.


Emik Avakian: An inventor who unfortunately was disabled, but that didn't stop him from contributing work that would help people similar to his condition. Notable contributions are the automatic wheelchair which dismiss the action of hand rolling and a breath operated typewriter.

1/ Today is #BlackHoleFriday, an annual science outreach event that, by complete coincidence I’m sure, is done on #BlackFriday. You’ll read lots of cool stuff about black holes on the hashtag. Here’s mine.


2/ Black holes are weird. Duh. People like to think of them as something like incredibly dense nuggets of stuff that sucks other stuff in. But they’re not like that.

3/ If you squeeze enough mass into a small enough volume, the gravity gets so intense that it’s impossible to escape them *if you get too close*. From far away, though, gravitationally they more or less act like anything with that much mass.

4/ So if the Sun turns into a black hole we wouldn’t get drawn in. In fact, we’d orbit it almost exactly the same way as we do now, though we’d freeze to death pretty rapidly, which, in the end, would still kinda suck.

5/ Black holes get weird *when you get close*. Anything with mass warps space — we feel that warp as gravity! — but black holes stretch space to its limit.

And since today is International Day of Women and Girls in Science, let's highlight a few of them - just a few women among thousands of others who helped shape the world we live in today.

Thread.


Dorothy Hodgkin discovered the structure of insulin after 36 years of work.

"I was captured for life by chemistry and by crystals."


Sophia Jex-Blake fought for women's rights to study medicine. She was involved in founding two medical schools for women.

"It seemed discreditable to Great Britain that all her daughters who desired a University education should be driven abroad to seek it."


Alice Augusta Ball developed the "Ball Method", the most effective treatment for leprosy during the early 20th century. She was 23.


Ada Lovelace is regarded as the first to recognize the full potential of computers and as one of the first computer programmers.

“That brain of mine is something more than merely mortal; as time will show.”

Cognitive Bias in Forensic Pathology Decisions was published today by Journal of Forensic Sciences

From the abstract “We examined all death certificates issued during a 10-year period in the State of Nevada in the United States for children under the age of six.” /2

We also conducted an experiment with 133 forensic pathologists in which we tested whether knowledge of irrelevant non-medical information that should have no bearing on fo- rensic pathologists’ decisions influenced their manner of death determinations. /3

The dataset of death certificates indicated that forensic pathologists were more likely to rule "homicide" rather than "accident" for deaths of Black children relative to White children. /4

“Participants read a vignette describing a not straightforward or simple case in which a 3.5-year-old child was presented to an ED with diminished vital signs and who died shortly after arrival. /5

SRI BANKEY BIHARI JI, VRINDAVAN (UP)

Very famous Krishna Mandir where Bankey Bihari Ji is worshipped and looked after as a child.
Bankey means “Bent at three places”.
Thakur Ji was worshipped in Nidhivan till 1863. This mandir was constructed in 1864 by Goswamis.
@LostTemple7


Legend says that Swami Haridas used to worship Krishna in Nidhivan.
Once, his curious disciples entered the forest but they were almost blinded by bright, intense light. Upon knowing this, Swamiji himself went there and after his requests, Krishna appeared with his consort.


Krishna, then, left back this black charming murti,which we see now, before disappearing.
A curtain is drawn before the murti after every 15-30 second. It is said that if one stares long enough into the eyes of Shri Banke Bihari, the person would lose his self consciousness.


Bankey Bihari Ji sports a flute only once a year on the eve of Sharad Purnima.
Darshan of His lotus feet can be done only on Akshay Tritiya every year.
There are no loud bells here and
no early morning Darshan can be done so that child Krishna’s sleep is not disturbed.

Right, screw it. Here's a thread on *that* FBLive by Alex Cairnie about #Govanhill. Lets do a watch-through shall we? (Mind, I'm a resident of Govanhill, and a sociologist. I'm also 5'3, and a visibly queer woman so if half his claims are true I should be living in terror)

00:30: Welcomes viewers and uses points out that his videos are only getting attention b/c they're 'horrific'. Directs folk to his Youtube page. So already clout hunting.

1:08: "I've been warned to stay out of Govanhill. I'm a marked man" (proceeds to use a beanie as a disguise)

1:30 "Laughing and joking aside, here's somebodys front garden." Proceeds to show litter and claim its thrown from windows and this is 'common'. I know a handful of streets with litter issues like this, but its neither common nor unique to #govanhill and other deprived areas.

2:10 "Don't be under any illusion I'm only showing you the bad bits" - only shows you the bad bits.

3:45: He's had offers of help, but hes said no because hes not responsible for 'anybody elses safety' Good lord.

5:01: "Its not that bad. But its not all good either" -Correct

6:00: TW: child abuse - He starts claiming to have been contacted by a health professional and told about child abuse 'in the area'. Huge ethical issues here as the 'professional' who has 'been in the game a long time' is reporting to Facebook Dude and not authorities.

Ok I was wrong about theHouse. 2 years of legislative gridlock = not fun. Few bills passing.

Control of the House is useless when it comes to keeping Trump from declassifying all the SpyGate docs. Or stopping an Inspector General from releasing a report.

Trump still gets control of judicial appointments so we can expect another 100 judges over the next two years. This time there’ll be no McCain or Flake playing the Maverick role with their swing vote.

That new margin in the Senate is huge if another Supreme Court seat comes open.

So from the responses I’m getting, people seem to think if Trump declassifies the Spygate stuff now, nothing happens.

Are you under the impression federal prosecutors have to wait until CONGRESS finishes an investigation and makes criminal referrals before the DOJ can act?

There’s a federal grand jury on McCabe right now. Did Congress ever finish it’s investigation and make a referral to the DOJ against him?

No.

BUT INSPECTOR GENERAL HOROWITZ DID. On finishing his McCabe leak report.

Funny how nobody remembers that.
