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?
Information conservation implies that it is that thing that does not change in time. That there is this bit that can't be changed. This is different from energy in that it is not an agent of change. Energy can be transformed, it's just the overall quantity remains the same.
Energy is what we would call a value and not something with an identity. When we speak however of information, that is of a bit, do we also imply an identity? That one bit over here is different from another bit elsewhere?
Are we speaking of the difference between a fermion (that has identity) and a boson (one that does not). A fermion is that elementary particle that is uniquely defined by its quantum features. The universe has a rule that fermions are unique (hence identity).
So when we speak about information, are we referring to uniqueness? If so, then information is different from energy. Energy is to bosons as information is to fermions.
How do fermions change their identity (i.e. change their quantum state)? Through energy that comes from the force carriers (i.e. bosons).
So to conclude, when you use the word conservation you imply a value, that is a quantity. When you speak of information, you imply a unique state.
That unique state is not time-invariant. It is incorrect to say that information is conserved. It's more apt to say that information is 'reconfigured'.
Now it takes exchange of energy to get to a specific quantum state. An atom can receive a photon or release a photon, this happens when its quantum state changes. There is no reconfiguration of information without an exchange of energy.
In a digital computer, we typically don't concern ourselves with the energy cost of transforming from one information state into another state. It is of course always present. Information in a computer always requires energy to change.
We also never care to use energy conservation rules to analyze the mechanisms of an algorithm. A computer is not a closed system. It draws energy from the wall that it is plugged into. (note: Wall is connected to the grid)
But here's the rub. A biological brain cares about energy conservation. A biological brain cares about where it's going to get its next meal. A biological brain isn't plugged into the wall that gets a steady influx of energy. (note: plants get it from the sun)
A biological brain cares about information about sources of energy. Information that is relevant for a brain is not the same as the information that is relevant to physics. Although both are related to energy.
A brain cares about information about energy. In physics, information is configured because of energy. These are just two different things. One is about energy and the other is the effect of energy. Let's not confuse the utterly obvious!

AGI Significance Paradox: As progress accelerates towards AGI, the number of people who realize the significance of each new breakthrough decreases.

Why is it that you can boil a frog in water without it jumping out if you gradually increase the temperature?

The problem for the frog is that it does not have the internal models to realize that there is a change in the water temperature. A cold-blooded creature like the frog has its temperature regulated by the external environment.

To recognize change, an agent must have an internal model of reality that is able to recognize this change. Unfortunately, a majority of the population do not have good models of human general intelligence.

In fact, even the simplistic dual-process model of system 1 and system 2 is not very well known.

Programming in abstractions is very different from a system that is capable of its own 'abstracting'. But what does abstracting mean? We only know of its inputs and outputs, but we fail to describe its inner workings.

I like this short video about living in space. This is because it makes you realize the gaps in your knowledge when you turn off something (i.e. gravity) that you have always assumed to be present.


Perhaps we can understand 'abstracting' better if we turn of many assumptions that we unconsciously carry around. Perhaps we need to get rid of the excess baggage that is confusing our thinking about abstraction.

Turning off gravity and living in space is a perfect analogy. We somehow have to turn off a cognitive process to understand the meaning of abstraction.

The first step to divorce ourselves from our habitual cognitive processes is to realize the pervasiveness of 'noun-thinking' .

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.

Abduction is that thought process where we renew our past, question our present, and reimagine our future.

It was C.S. Peirce, a century ago, that coined the use of this term to describe a thought process that would convey hypothesis making.

A little over 50 years ago, proponents of Artificial Intelligence, proposed that deduction would be the core feature of human intelligence. This idea was driven by the bias towards formal logical systems and the emergence of computers.

This approach was in stark contrast to cybernetics (introduced a decade early) that proposed that dynamical systems were a model for intelligence. The descendant of this approach was coined as artificial neural networks.

This dynamical systems approach was later understood as being similar to an induction based thought process. Deep Learning leads to what can be characterized as Artificial Intuition.

Nice to discover Judea Pearl ask a fundamental question. What's an 'inductive bias'?


I crucial step on the road towards AGI is a richer vocabulary for reasoning about inductive biases.

explores the apparent impedance mismatch between inductive biases and causal reasoning. But isn't the logical thinking required for good causal reasoning also not an inductive bias?

An inductive bias is what C.S. Peirce would call a habit. It is a habit of reasoning. Logical thinking is like a Platonic solid of the many kinds of heuristics that are discovered.

The kind of black and white logic that is found in digital computers is critical to the emergence of today's information economy. This of course is not the same logic that drives the general intelligence that lives in the same economy.

COVID Masks: Mechanistic View: Part 2: Fine Aerosol Emissions:

Masks may increase fine aerosol emissions from: 1) nebulization of large droplets into fine aerosols, or 2) friability of certain mask materials creating "aerosolized fomites."

Please share:

Here are the studies:

The question is whether facemasks are actually a source for viral aerosols by:

1) Masks get saturated by large "respiratory droplets" containing viral molecules. Air turbulence against trapped droplets may create aerosols that eventually diffuse around edges. Continued...

Trapped droplets potentially get pushed through the filter media of the mask, getting nebulized into aerosols.

Particles don't always stay in the mask:

Study: Ha'eri 1980

Title: The efficacy of standard surgical face masks: an investigation using "tracer particles"

Albumin tracer particles put inside a surgical mask were dispersed into the room by breathing.

Viral molecules can get airborne from air turbulence.

Study: Liu 2020
Title: Aerodynamic analysis of SARS-CoV-2 in two Wuhan hospitals.
SARS-2-COV sub-micrometer aerosols not tightly bound to surfaces, get airborne when PPE is taken off.

1 of 16: WE ARE ALL JEWS HERE: THE STORY OF RODDIE EDMONDS

One of the most moving and relevant stories of the Battle of the Bulge, or any American Soldier in any war, is that of Master Sergeant Roddie Edmonds, a Knoxville, Tennessee native, who served with the 106th Infantry.


2 of 16:

Roddie was captured early on in the Battle of the Bulge, on December 19th, when Panzer forces plowed through his unit.

He, along with almost his entire regiment, was forced to surrender.


3 of 16:

The men were transported to the Stalag IX-A POW camp in Ziegenhain, Germany.

Roddie was the senior enlisted American Soldier at the site. As such, he was the conduit between all American Soldiers and their German captors.


4 of 16:

In late January, the camp’s commandant, Major Siegmann [pictured here], ordered Roddie, a Christian, to identify all Jewish Soldiers and order them to stand in formation by themselves the next day.

[Jewish Soldiers were a minority within American units]


5 of 16:

Throughout WWII, captured Jewish Soldiers were often tortured and then killed by their German captors.

In fact, Jewish Soldiers had been told to bury their dog tags before capture. The dog tag identified Jews with the letter “H” for Hebrew.

When I was 25, I worked as a legislative assistant in the Missouri General Assembly.

It was a dream job, honestly.

But that dream dissipated the day the #MoLeg decided to name Rush Limbaugh as an “honorable Missourian” and place his bust in the “Hall of Famous Missourians.”

1/

The Hall of Famous Missourians sits in the Missouri State Capitol.

There are busts of Mark Twain, Dred Scott, Josephine Baker, Harry Truman and other legends of history.

The day I learned Rush Limbaugh would join their ranks, I thought it was a joke.

2/

We received phone calls from constituents appalled that Missouri would honor a man who had become infamous that year for calling a college student a “slut.”

And who just that week had continued spreading the racist birtherism lie about our then-President, Barack Obama.

3/

What I learned that day is that it wasn’t *despite* his racism, but because of it that he received this award.

It’s because he created a universe where it was permissible to lynch with language America’s first black President.

4/

Several State Representatives and their staffers intended to protest the vote and the selection.

By the time we made it to the doors of the House Floor, we weren’t allowed in. It was Republicans only. The doors were locked and secured by the Highway Patrol.

So much #FactCheckBait being put out by IT Cell today and so many people biting.

What is #FactCheckBait? Fascists putting out tweets or messages with very obvious rebuttal properties. So non-fascists are distracted by rebutting or fact checking them. And the fascists get more name recognition. What have the top sanghi twitter accounts done other than provoke?

Why are so many sanghi bigot handles famous & well followed on Twitter despite having no notable quality other than getting called out by liberals? Cos that's all it takes. If they can fool liberals into QTing or even screenshot-ing them, they become heroes and then are like


Another example of #FactCheckBait. This sanghi wants you to identify them while pointing out the very obvious flaws in their logic. This sanghi is counting on it to improve their visibility. Don't give them that oxygen. Call them out like this, without IDs, if you must.


As pointed out by @bongopondit, peak #FactCheckBait was Ted Cruz saying rejoining the Paris climate agreement was about appeasing Paris not Pittsburgh. He knows it's BS. He's an evil psychopath but not dumb. He wants you to QT him and distract from his insurrection efforts.

Time for a Thread🧵On yesterday’s “F&O Pe Charcha - Diary Of An Option Seller” with @Mitesh_Engr by @Paytm Money

Why Gain/loss ratio is important that the batting average
• More than the Win Loss ratio check the total Gain /loss ratio
• If your avg loss is 1% and avg gain is +5% then even if you are losing in 7 positions and winning in 3 out of 10 still you will be net profitable

Treat Trading as a business:
• Stick to a single strategy. Eg: A restaurateur usually wouldn’t be changing his recipe on a daily basis
• Mitesh Sir only works on BO or BD strategy, as he is a versatile trader

• Any trader should atleast experience 3 scenarios i.e. bull, bear & consolidation
• Target 4% per month i.e. 48% p.a.
• Option buying requires skill, everyday there wont be huge momentum, so buying options won’t yield good results, but high chances of falling into a bad habit

Stock Selection:
• In F&O segment there are ~150 stocks
• Not everyday all stocks will move
• Only 5-7 stocks move upside or downside
• Focus only these momentum stocks
• Check which one is moving
• Range BO/BD never disappoints. BO/BD from a rectangle (consolidation)

Thirumalai Murugan Kovil
#Panpoli
#TamilNaduTemples 🚩

Thirumalai Murugan Temple is located in Tenkasi district of Tamil Nadu. Muruga is worshipped as Thirumalai kumarasamy. Temple is situated near Kerala border and known to be where Shri Murugan gave darshan to Rishi Agasthiar


Devi is worshipped in the temple as Thirumalai Kaali amman

Sthala Puranam says that, there was a priest named Poovanbhattar of Thirumalai Kaali amman. Murugar appeared in a dream of the bhattar and said to find a Vigraham, lying in particular place which is of Thirumalaikumaran


Bhattar conveyed the news to the Pandalam Raja and they went to find out the vigraham. Surprisingly ants showed the way to find the Vigraham. Thus Murugan vigraham was found and Prathista was done here. There is a lake with pure water on the top of the hill


which is said to be created by Agasthiyar. It is believed that kannaki of
Chilapathikaram visited here before going to Kerala. Sapthamathrukkal also worshipped Murugan here. Kanthashashti Thiruvizha is very famous here.
