The nano drones are the most multi-use tools that engineers ever created.

Nano drones are small robots that are like smoke. Those drones can get their energy from photovoltaic cells and radio waves. They can also use miniature batteries. The problem with nano drones is their small size. Making a suitable power source for the extremely small machines and their computers is problematic.

The nano drones can revolutionize surgery and in those cases, radio transmitters can send the required electricity to drones. Or the catheter can equip with light that delivers energy to the miniature photovoltaic cells.

Those drones are smaller than cells. Those miniature drones can operate on the human body. And they can interact with the user by using BCI (Brain-Controlled Interface). So the nano drones can act as an intelligent immune defense. But the fact is that the nano drones can operate independently and use the same networked computing solutions that larger size drones use in independent drone swarms.

The miniature drones can swim in the fuel tanks. They can search the leaks. And then those drones can swim to the hole and close it. They can form a temporary plug until the repairers can make the requirement. There is the possibility that the nano drones are also covering the structure of the future aircraft. Those drones can send the vertical radiation signals that are denying radar echoes.

Or the swarm of miniature drones can use as an intelligent decoy that pulls incoming missiles to them. There is the possibility that tomorrow every submarine is followed by a swarm of nano drones. Those nano drones can observe the vibration in the water and otherwise observe hostile things.

The nano drone swarms can also operate in recon missions. They can slip into the clothes or bodies of the person. And then they can release in the operational area. The nano drones can read the data that is traveling in microprocessors. The drone just "sits" on the microchip. And then it transmits data to the receiver.

The nano drones can also use in elimination missions. They can slip into the targeted person and destroy blood vessels.

The term decentralized computing means that the participants of the data network can share their missions. The same thing works with all kinds of microprocessors. The system cuts the program into pieces. And each piece is equipped with an identifier. That helps the participants of the operation can connect the pieces back to their entirety.

The idea is similar to the quantum computer where the binary data must transform into a qubit. The drone swarm operates as a neural network. And that means the system can operate and learn very fast. The learning network has the operational models stored in their memories. Then the system starts to test what is the best of those models. The system takes an image of the operational area and object of the operation. Then it starts to select the operational models.

That thing can happen by sharing the drone swarm in pieces. Then the system shares the action models with each of the drone swarms. And then it can compare which model is the best. Values that the learning machines can use is the number of damaged drones. The time that the system is used for the mission and then the success of the mission. Then it can store the mission and mission area in its memory. That is because it can use the complete models it faces another similar problem.

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....
