The SAR technology



SAR or Synthetic-aperture Radar is a tool that is giving extremely good images from the ground. In that technology radio or microwaves are put to jump from the ground. And that helps to create the 3D maps of ground areas. The SAR radar is basing the idea that the radar is put on an instantly moving platform.

And makes the system possible to detect small-size, 3D targets from the ground. The wavelength of the radar determines how big objects they can see. When radar radiation comes from different sides it can create a structure's 3D models. Modern commercial SAR systems can detect even single vehicles from the ground through clouds.  The SAR technology allows us to see what happens in the Ukraine war.

The virtualization of the SAR systems is making them very hard to destroy. The small-size satellites can operate as a swarm. And the laser systems can be used as the laser-SAR systems. But the laser rays can also use to create the radio waves. When lasers are giving the electromagnetic stress to air molecules they send electromagnetic radiation like radio waves. The laser ray can use to create the virtual antenna for the radar system. The system can use two laser rays. 

One is giving the EM stress to air molecules. And the second one measures the echoes from the environment. The next-generation quantum systems can make it possible to see even a single sand bite from the ground. The idea of those systems is the same as the scanning tunneling microscopes. They can hover things like electrons or protons at the front of the radar. 

One of the things that this system can use is the water molecule. In that case, the water molecule will anchor to the layer by using the molecule's polarity. The hydrogen atoms can be in the layer and the oxygen can be outside. Then the system gives electromagnetic stress to the molecule that acts as the antenna. That type of system might be the key to the radar technology of the future.

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....
