The dangers of 3D printers are visible.


Image (DailyMail/Teenager, 18, is charged after 'home-made 3D printed semi-automatic rifle is found inside an Australian home': 'It's deeply concerning')


The internet of things shows its danger when an Australian teenager printed a fully working semi-automatic assault rifle by using a 3D printer that is bought from the shop. That assault rifle is made of plastic. That thing makes it extremely dangerous because those guns can pass the regular security check of airports. 

The 3D printer can make it possible to turn any CAD image into physical merchandise. This thing is the new type of CAD/CAM (Computer-Aided Design/Computer-Aided  Manufacturing) robot. The 3D printer systems are more flexible than regular robots. 

In a 3D printer system, the system turns plastic or metal wires into any merchandise. And that means there are no non-necessary parts onboard. This makes 3D printers suitable for supporting spaceflight. In that case, there are no spare parts that are not needed on board. 

Things like plastic and carbon fiber can make it possible to make stealth arms. Those weapons cannot detect by using regular metal detectors. In the case of plastic, the quality of those guns is poor. But the working gun is always deadly. 

Carbon fiber can be tougher than steel. And carbon fibers are the things that can use to make a gun that has high quality and what is invisible to metal detectors. 

In the case of crimes, the working gun is enough for criminal actions. And the criminals might destroy their guns after use anyway. The 3D printers can handle carbon fiber or make metal parts that make it possible to create more high-quality weapons. The thing that makes metal-printed weapons poor is the gas bubbles in the structure. 

And if the printer operates in a vacuum. That thing solves the problem of quality. So these kinds of things are making the 3D printer technology dangerous. The next-generation weapon dealers can simply use 3D printers to make the firearms for their customers. And people like the South-American narcotics mafia might be the potential customers for that kind of stuff. 

The 3D printer technology is a bad thing in the wrong hands. There are suspicions that those systems are used also for making the illegal pirate spare parts for machines. Also, pirate scissors and other kinds of things are possible to create by using 3D printers.

Antimatter motor

Antimatter motor Antimatter would be an effective fuel for interstellar spacecraft Antimatter would be the most effective power source in the world. It will be the most suitable motor for interstellar spacecraft, but the problem is that thing is very reactive. And actually one of the biggest problems with this kind of motor is that the gram of antimatter would turn the entire planet to the molecular nebula. So this kind of motor can produce only outside of our solar system. Producing antimatter would need large particle accelerators, and that kind of systems might look like giant donuts, what is floating on the space. There are two ways to create the antimatter motor, one is to store the anti-ions in the magnetic bottle, where the pushing magnetic field will keep those ions away from the wall of the bottle, and then the antimatter would conduct to the water or some other particle. The huge explosion or annihilation reaction would send the rocket to a very high speed. The antimatt...

Thoughts about strong leadership

Thoughts about strong leadership Everybody knows, how the dictators would rise in the power of the nation, and the thing what makes people supporting those persons is that they offer strong leadership as the way to make nation proud. And also they have always the same parroting, the foreigners and other nations have a too strong influence in the country. But what makes those persons like some Robert Mugabe or Kim Jong Un to think that they are only possible leaders, and why people would need them? Why there is nobody else allowed to try to come to the head of the state, or even try to challenge those leaders? If they are so popular as they want people to think or believe, why they don't tolerate any kind of opposition if they are done so good and big actions for their people, that they are celebrated in every home in their country. The thing that would return the morale and spine for the nation is the strong leader, who would put the state back in order and row. The thing is ...

Next-generation nanotechnology can be independent-operating molecule-sized robots.

 Next-generation nanotechnology can be independent-operating molecule-sized robots. "A DNAzyme (red) uses its binding arms to dock at a specific location on an RNA strand (yellow) and then cleaves it at its core. High-resolution, real-time NMR, Electron Paramagnetic Resonance, and Fluorescence Spectroscopy." "As well as Molecular Dynamics Simulations are used to identify the structure. And catalytic mechanisms of the DNAzyme. Credit: HHU/Manuel Etzkorn" (https://scitechdaily.com/dnazymes-how-active-dna-biocatalysts-that-destroy-unwanted-rna-molecules-work/) The active DNA catalysts are the gate to DNA-controlled, independently-operating, molecular-size nanomachines.  The DNAzymes or active DNA biocatalysts are next-generation tools for destroying unwanted RNA. The DNA molecule is one of the tools. That can use for controlling molecular-size machines. DNA is like a chemical computer program. And if the researchers can make synthetic DNA that can make exactly what the...
