Everything in us is in our DNA.

 Everything in us is in our DNA. 


When we think about the topology of the DNA and its connections with climate and environment we must realize that our bodies and our cells cannot match with all types of environment. Things like chemical environment and animal poisons can also affect things which skin color is the best. If animals like snakes are creating white poison, the black skin is better. But if the major toxic agent is black that thing is easier to see from white skin. Also, things like blood leaks are better visible on blond skin. 

Genetic adaptation makes African people black because dark pigment protects cells against sunlight. But why do northern people have white skin? The reason for that is in the environment, at spring the snow and sun create scattering light and the dark skin cannot protect cells against powerful UV light. And also dark skin can cause situations. 

Where cells are overheating in changes of temperature. In cold weather, people must protect themselves against the environment by using strong clothes. When we are looking at images of people around the world people who live in stable temperatures have black skin.

But people like Beduins and Europeans have blonder skin than people who live in stable temperatures. The temperature changes very much during the 24 hours. And if the skin is black. The temperature can rise in cells very fast. And it can cause damage. The white skin is better in the case where cells must let radiation travel through it to stabilize temperature in them. But white skin lets UV radiation travel the DNA. That means there is no perfect skin or perfect genomes.

The same thing that can make people adapt to certain environments is the risk in another environment. There are also many other things than just radiation that can cause cancer and affect the ability to survive. The cancer is not the only thing that the wrong genome can cause. Genetic disorders can deny the ability to get descendants. Or it can cause the situation that the creature cannot find food. Whenever a life circle is changed that thing forms a mark in the DNA. 

Skin color is the most visible example of genetic adaptation. But things like the ability to produce red blood cells are the things that are necessary for people who live in high areas. That thing causes problems with cancer, because if cells are splitting too often. There is the possibility that a person gets leukemia because of endemic carcinogens stress. Whenever a cell divides it has a higher risk of getting a mutation.

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....
