The tale of the Derringer "hand cannon"

Derringer-pistol is a very powerful weapon, what is made for close-range self-defense. It's small, effective and dangerous. There are many calibers of this famous weapon, and the CIA has made the agent-version of this pocket pistol, what looks like cigarette-lighter. If that box is airtight, and the weapon made by anti magnetic materials, that could be easier to carry in the aircraft. But there is one thing, what made this small size pistol very well known. It was used in the assassination of President Lincoln, and this made the very big reputation for pistol, what was found in pockets of gamblers and also many persons of law enforcement carried it for the backup gun for close combat situations.


The normal way to carry this weapon was in the holster, what was in the arm of the skirt, where it was easy to take, and where normal people didn't know to look at it. But there is one thing, what made the weapon what was used in the Lincoln case interesting. That particular 44-caliber prime-lock pistol had the rounded barrel, what could allow using extended barrel in that weapon. The extended barrel would be equipped with the screw thread and the barrel could veil as the cane.


There is the story, that modern Derringers have been equipped with the hexagonal outer layer, because that would be confessed, that the screw thread was not in use. But in fact, the screw thread could be inside the barrel, and the extended part could be put inside the veil. The extended stock could be made by iron stick, and it could be similar, what is used in the assault rifles. The pistol grip must be equipped with the piece, where this stock could be put. And the extended barrel allows using the telescope sight, and this could be one version of this famous handgun, and that allows to use it also for hunting or some other missions. If the caliber is powerful enough, this weapon could be effective many things.

The LK-99 could be a fundamental advance even if it cannot reach superconductivity in 400K.

The next step in superconducting research is that LK-99 was not superconducting at room temperature. Or was it? The thing is that there is needed more research about that material. And even if it couldn't reach superconductivity in 400K that doesn't mean that material is not fundamental. And if LK-99 can maintain its superconductivity in 400K that means a fundamental breakthrough in superconducting technology.  The LK-99 can be hype or it can be the real thing. The thing is, anyway, that high-voltage cables and our electric networks are not turning superconducting before next summer. But if we can change the electric network to superconducting by using some reasonable material. That thing can be the next step in the environment. Superconductors decrease the need to produce electricity. But today cooling systems that need lots of energy are the thing that turn superconductors that need low temperatures non-practical for everyday use.  When the project begins there is lots of ent

Black holes, the speed of light, and gravitational background are things that are connecting the universe.

 Black holes, the speed of light, and gravitational background are things that are connecting the universe.  Black holes and gravitational waves: is black hole's singularity at so high energy level that energy travels in one direction in the form of a gravitational wave.  We normally say that black holes do not send radiation. And we are wrong. Black holes send gravitational waves. Gravitational waves are wave movement or radiation. And that means the black holes are bright gravitational objects.  If we can use water to illustrate the gravitational interaction we can say that gravitational waves push the surface tension out from the gravitational center. Then the other quantum fields push particles or objects into a black hole. The gravitational waves push energy out from the objects. And then the energy or quantum fields behind that object push them into the gravitational center.  The elementary particles are quantum fields or whisk-looking structures. If the gravitational wave is

The CEO of Open AI, Sam Altman said that AI development requires a similar organization as IAEA.

We know that there are many risks in AI development. And there must be something that puts people realize that these kinds of things are not jokes. The problem is how to take control of the AI development. If we think about international contracts regarding AI development. We must realize that there is a possibility that the contract that should limit AI development turns into another version of the Nuclear Non-Proliferation Treaty. That treaty didn't ever deny the escalation of nuclear weapons. And there is a big possibility that the AI-limitation contracts follow the route of the Nuclear Non-Proliferation Treaty.  The biggest problem with AI development is the new platforms that can run every complicated and effective code. That means the quantum computer-based neural networks can turn themselves more intelligent than humans. The AI has the ultimate ability to learn new things. And if it runs on the quantum-hybrid system that switches its state between binary and quantum states,
