3D printers and drones can be game changers in next-generation civil and military missions.

"The new drone is allegedly similar to the Chinese MD-22 hypersonic drone". (Interesting Engineering)

The Chinese hypersonic drone challenges and maybe beats the F-22 in aerodynamic constructions. That kind of drone can be extremely dangerous for all targets. The hypersonic drone that hits a target using hypersonic speed releases lots of impact energy to the target. And even if that system is a recon drone, the impact with speeds between Mach 7-10 with ships releases lots of energy.

"Ex-Google CEO Eric Schmidt has quietly created a company called White Stork, which plans to build AI-powered attack drones". (Interesting Engineering)

The A-10 Thunderbolt destroys a tank with a single 30 mm. uranium ammunition that speed is Mach 1,5. If the tank is not protected, with reactive armor. Reactive armor protects tanks against single ammunition. The rate of fire of 30 mm. GAU-8 Avenger cannon is 3000 rounds per minute. That means the cannon stripes reactive armor away.

The Houthi rebels use drones as well as Ukraine. The underwater and surface traveling drones have shown their abilities in Ukraine. And the Houthi rebels at the Red Sea following that thing interesting. Those rebels used drones to attack ships. And that thing shows that also rebels and guerillas are interested in drones.

The Ukrainian military shows how vulnerable factories, fuel supply systems, and electric wires are in Western countries. The next step is that organized crime starts to use drones against their enemies. Drones can also protect areas like government installations, but they can also used to protect drug laboratories. Mafia with other crime gangs can use drones to attack their enemies.

The startup develops container-size 3D manufacturing printer platforms in Ukraine. And that thing tells about the integration between drones and their manufacturing systems. A long time ago, I wrote about drones that 3D printers can manufacture near the battlefield.

And that kind of system can increase the production of small-size kamikaze drones. The 3D printer systems are the next tool for the military. Those systems can produce spare parts for aircraft and even tanks. They also can produce things like rockets and ammunition near combat areas. That thing can be the new step in robotics, drones, and AI-based warfare.

The new loyal wingmen drones can act as remote-controlled or autonomous recon units, that can search enemy radars, and then send that data to unmanned fighters. Then those drones can also act as attack systems that operate like supersonic "Predator" drones. Those systems can attack against threats by using bombs and missiles.

Or they can make kamikaze attacks against enemy installations. Those drones can also pick up enemy missile fire to them. Which helps the mission of the manned fighters. Those drones might predict new types of cruise missiles that can return to base if they are not needed.

NASA works with autonomous lunar rovers. Those rovers are lightweight. And they can travel to the dark side of the moon. And then return to the side, that is visible to Earth, transmitting their data to ground control.

Similar surface-operating drone cars can used in undersea civil and military missions. They can search for poisons and things like mines from the beaches. Those rovers can slip over the enemy line and then transmit information to surveillance platforms. The military rover can equipped with antitank missiles or some other weapons, and they can use those weapons against any target that they see.

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....
