How do the DNA-based sensors work?

The DNA-based sensors use the DNA molecule as the sensor. The idea is that the DNA molecule or its head can hover around the layer and act like the stylus of an old-time LP player. In some versions of DNA sensors, there could be an iron bite at the end of the molecule. There is a possibility to use that iron bite to measure the magnetic field. There is the possibility that the radio waves are pointed to a certain target through that iron stylus.

The radio (maser) wave will shoot to the iron that drives those radio waves to a certain target. The system can observe the reflection. But if the iron bite slides above the magnetized or electrically stressed layer the system can measure the electricity in that stylus. Or the system can measure the position of the DNA relative to the level. That allows operators to see the differences in the shape of the layer.

When the layer goes farther the magnetic effect on DNA is turning weaker. And that affects the position of the DNA. The idea is similar to the magnet that is connected to the libra. When the magnetic layer is below it the distance to the magnetic layer affects the pulling force of the magnet.

There is a possibility to observe the differences in the length and position of the DNA molecules by using the laser microscope that can measure the changes in the forms of that molecule. In some other versions of DNA-based sensors, The DNA will position around the measurable object. The DNA tweezers are based on the idea that the electricity will pull the last base pairs of the DNA around the object. In that kind of nanotechnical system, electricity will conduct to the object that must transport.

In the measuring system the DNA position over the measurable object. Then the DNA molecule would rotate around. And the laser microscope measures the changes in the position of the last base pairs of the molecule. In the last version the ion will be shot through the DNA molecule vertically and the effects of that thing can notice by searching the effect of that thing on the DNA.

The idea is similar to fullerene nanotube-based sensors. In those sensors, the laser light will shoot sideways through the nanotube. When the particle moves through that tube. The sensor detects its shape by using laser light. And that kind of system can find many new things from the world of subatomic and atomic worlds.

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.
