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!

A children's book written in 1954 inspired by Wiener's Cybernetics that explains some common day analog systems:

Analog computation originally meant the construction of a simulation of another system by means of a mechanical or electrical system that represented the same dynamics as the physical system. That is an analog of what's being simulated.

Nobert Wiener generalized this idea in Cybernetics to describe control systems that through negative feedback promoted stability.

W.Ross Ashby argued that negative feedback was insufficient for maintaining the stability (homeostasis) of complex system. Ashby proposed the Law of Requisite Variety.

These machines that 'seem to think' are examples of what was known as analog computation. Cybernetics, control theory, biology are examples of analog computation. But what does this mean other than being the opposite of discrete/digital computation?

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.

In physics, energy is that which is causally invariant or symmetric with respect to time. Said differently, energy is never created or destroyed, it is conserved in the universe.

Now there is a question about information. Is information causally invariant? Does information remain the same with respect to time? To understand this, let's first understand what energy is, then attempt to understand what information is.

The strange thing about energy is that it is this universal currency that seems to be interchangeable between the different forces in nature (i.e. electromagnetic, strong, weak and gravity). It is that thing that makes change possible.

Now let's assume that the universe is computational in nature. That is, anything we see in nature is a consequence of computation. That is, there is computation underneath the physics that is driving the universe to change.

What does it mean then that information is conserved in this computational universe? Also, how is energy conservation related to information conservation?

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.

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.

Did we get dietary saturated fats all wrong? The #HADLmodel provides a new understanding and an opportunity to get it right. THREAD👇👇👇
@simondankel @kariannesve

Increased dietary saturated fatty acids lead to increased cholesterol in lipoproteins, but we don’t know why. Enter the #HADLmodel, which explains changes in lipoprotein cholesterol as adaptive homeostatic adjustments that ensure optimal cell membrane fluidity and cell function.

We propose that circulating lipoproteins enable appropriate redistribution of cholesterol molecules between specific cells and tissues, to accomodate changes in dietary fatty acid supply, due to our omnivore nature and variable intake of fatty acids. #HADLmodel

Our #HADLmodel implies that circulating levels of LDL change for protective, not for pathological reasons; an SFA-induced raise in LDL cholesterol in healthy individuals is a normal response, while a lack of this needed response may reflect a deeper pathology in lipid handling.

Circulating lipoproteins may change for pathological reasons, when regulatory mechanisms become disrupted by pathogenic processes related e.g. to inflammatory processes. Diverging lipoprotein responses in healthy versus metabolically unhealthy individuals support this view.

Where do most of the researchers and inventors around the world appear today? What is their mother tongue?

1) OBSERVATION: The frequencies are changing. I would have to assess stats on the electromagnetic field to see its fluctuations. All I know is, I am highly sensitive to energy/frequencies, and they are changing, because…

2) 2 Weeks ago, my dog was effected by it as well. He is hearing things that aren’t technically audible. I can tell by his body language and sounds. One week ago I began feeling a pressure in my head and ears. It wasn’t painful at all, but it was intense for a bit.

3) It reminded me of taking off in an airplane a bit. I felt like I was in a vacuum. It went on and off for a couple of days. I’ve picked up on frequencies and high pitched sounds (not audible to most) for 30 years, and today my right ear began to ring for longer than usual.

4) This is nothing unusual for me, with exception of the duration. This happens often with me. No, it’s not tinnitus. Only this time, when I spoke, there was reverb creating a high pitch in my ear from my voice. This lasted for about 30 minutes. It did not hurt, just annoying.

5) So yes, the frequencies are changing. What this means exactly, I am unsure of at the moment. Some will say electromagnetic fields, others will say ascension, and some will say pole shift. I honestly can’t say at this very moment.

I think we have to expand our thinking about the toroidal sphere even more. When looking at maps, I noticed the da Vinci map, from 1514, which uses the Reuleaux Triangle. This triangle is formed from 3 intersecting circles, and is in the center of a trefoil.


The trefoil is the focal point in many gothic structures, repeatedly and prominently shown. It is represented in many ways. ‘Going down the rabbit hole’ now makes sense, if you understand the center point of the ears is the center of the torus, with the rabbit trefoil.


The trefoil can be found within the toroidal field. Here is a fun site, where you can manipulate it yourself. https://t.co/FCMcybuuFC


The wiki page makes it seem like there isn’t much of importance with the Reuleaux Triangle, besides being used for coinage, or some stupid bike. But the Wankel engine is an interesting engine, using this geometric design https://t.co/ayPOgkAqGN

So, I want to talk about how sexual harassment and fair pay are linked at Google (and beyond), because I think that's an angle that isn't being highlighted enough in the coverage of these walk-outs. I'm going to frame it largely around my personal experience there. Thread.

When I was sexually harassed by the director of the area I was working in, I was afraid to report it because I was worried that "getting him in trouble" would result in the subtle retaliation of missed leadership opportunities.

I wanted to continue working on the team I was on, because I'd gained a lot of very deep knowledge and expertise in that area, as well as reputation and camaraderie with the other folks working in that area. I didn't want to make the situation more "difficult."

To get promoted at Google, several need to happen: 1. you need opportunities for ownership and leadership above your current level (basically, opportunities to show you're working at the next level you're trying to get promoted to). The work you're "assigned" has a big impact.

2. You need glowing reviews from peers, *at or particularly above the level you're hoping to get promoted to.* Basically, you need people a lot more senior than you to say you're doing awesome work.

Light travels at about 1 foot per nanosecond.

Hold your hand up 12 inches from your face: you’re seeing your hand as it was a nanosecond ago. Everything you look at is, to one degree or another, in the past. The farther away in space, the more ancient in time.

You can’t see the Sun as it is now, but you can see it as it was about 8 minutes ago. You can’t see Alpha Centauri now, but you can see it 4.4 years ago. You can see the Andromeda Galaxy as it was 2.5 million years in the past. And so on.

With powerful telescopes, we can see galaxies whose light has been traveling to us for more than 13 billion years. We see them shining in a universe that’s still young, where gravity has just begun to pull matter together into stars and galaxies.

We can see something even more distant, and more ancient, than the first galaxies. If we peer out far enough, in between the galaxies, we can see parts of the Universe that are so far away, it has taken the light from that distance almost the entire age of the cosmos to reach us.

Gather round, Gentle Readers. It is time I tell the story of the worst decision I ever made in an office. Some of you have heard this. Some have not. Whatever you do in your office today, this week, the rest of this year, you can console yourself by recalling this tale.

A long time ago, I was a talent agent. I worked for a woman named Susan Smith, who had her own small boutique agency. She was known for three things:

1. She had fantastic taste in clients. If there is someone you admire, odds are good that at some point, she was their agent,

2. She could negotiate a deal like few who have ever trod the earth. Casting would give her all the money they had budgeted for that part, plus a little more, plus promising to get her dog Barnaby groomed. She was magnificent to watch.

3. She was insane.

I'm sure you're thinking, "Quinn, it's the entertainment industry, they are all insane." Yes, many are. So consider this; if you told someone you worked for Susan, people who worked for insane people would look and you and whisper, "I hear she's insane."
