Yale researchers discovered why the human brain is different.



"Yale researchers have identified human-specific features in the prefrontal cortex".(Scitechdaily.com/Yale Scientists Discover Clues to What Makes the Human Brain Different)


Yale researchers mapped physical differences in the human brain. There found multiple different cell types in the human brain. Researchers mapped cell types that are common with all species. And they found also five cell types that are common only in humans and chimpanzees. One of the most interesting founding was brain-specific immune cells. 

That kind of research might answer why the human brain is so powerful. But also the things like brain-specific immune cells can give a tip, on why somebody will get things like brain cancer or Parkinson's. There is more about that research in the link below this text. 

This kind of research can answer the question, why do only humans have the ability to think abstractly? Abstraction is the ability to model things in mind. And that ability allows we can plan things and transfer data to other humans by using spoken language and drawing pictures. 

When we know how the human brain works we can also get an answer, to why our brain uses only a small part of the energy that computers need. Another interesting thing is why only humans seem to have psychosomatic diseases. 

Are those diseases the result of the situation that the brain cells are connecting with the wrong neurons? That might form the wrong type of virtual neuron that can launch a chain reaction and that thing pulls other neurons to the same situation. 

The brain is the neural network that can interact with other networks.  For operating effectively, the neural network requires multiple connections. But thinking and planned actions require that the neural network can operate in two directions. When the senses see something the neural system must hold the operation. 


The ability to postpone the action helps humans to see if there are other predators near the prey. Most of our abilities are connected with getting food. And the ability to postpone an attack makes it possible to make sure that nothing is following the hunter. 

The ability to postpone an attack makes it possible that individuals can collect more information about their environment. If a hunter is alone and sees something like a small antelope that is suitable for dinner the stone-age hunter must first see that there are not some other predators or overwhelming hostile villains before that person starts to attack. There is always the possibility that some savages are trying to steal that food. And that's why we can postpone things.

Schrödinger's cat: and the limits of that idea.

"In quantum mechanics, Schrödinger's cat is a thought experiment concerning quantum superposition". (Wikipedia, Schrödinger's cat). But the same thing can use as model for many other thought experiments.  Sooner or later, or at least in the ultimate end of the universe, the Schrödinger's cat will turn into wave movement. The information that this cat involved exists but the cat does not exist in its material form. The information doesn't ever vanish. It just turns its shape.  We are all trapped in the universe and time. The universe is the space that is entirety to us. There are no confirmed other universities. But the multiverse is a logical continuum for the expanding galactic megastructures.  The problem with natural things is this. They are black and white. They exist or do not exist. Could there be something, that exists and not exists at the same time?  Scrödinger's cat is thinking experiment about case their cat is not dead or not alive. But in this...

The string theory offers a new way to calculate Pi.

"Scientists discovered a new series for pi through string theory research, echoing a 15th-century formula by Madhava. By combining Euler-Beta Functions and Feynman Diagrams, they modeled particle interactions efficiently. Credit: SciTechDaily.com" (ScitechDaily, String Theory Unravels New Pi Formula: A Quantum Leap in Mathematics) People normally think that. The pi is the ratio of the circumference circle's circumference to the circle's diameter. The Pi is a mathematical constant 3.14159..., the endless decimal number. The Pi is interesting because developers can use that decimal number to make the encryption algorithms stronger.  The idea is that the encryptions program hides the message's original ASCII numbers by multiplicating those numbers with some decimal number. Or the system can add some numbers to those ASCII numbers.  "Aninda Sinha (left) and Arnab Saha (right). Credit: Manu Y" (ScitechDaily, String Theory Unravels New Pi Formula: A Quantum Le...

There are always more than three actors in the real world.

"An international research team is advancing precision timekeeping by developing a nuclear clock using thorium isotopes and innovative laser methods, potentially transforming our understanding of physical constants and dark matter. (Artist’s concept.) Credit: SciTechDaily.com" (ScitechDaily, Unveiling the Thorium Nuclear Clock and Its Time-Twisting Secrets) From Three-body problem... There are no pure three-body systems in nature. There are always more than three components in the system. For making real three-body systems we must separate those three bodies from the environment. Otherwise, there are stable effects. But nobody can predict some effects like distant supernova explosions or sun eruptions.  And one of those things that affect all bodies is time. When radioactive materials decay. That affects the stability and symmetry of the object.  Energy levels affect the existence of things like neutrons. The thorium atom clocks are next-generation tools for time measurement....
