Curved terahertz radiation can offer a new communication tool.

Terahertz radiation is a tool. That is used for new types of radars and observation systems. Teraherz-scanners can give new tools for airport security. Those scanners can find hidden weapons in clothes. But terahertz radiation can also for communication. 

The newest tool for information technology is terahertz communication. The curved terahertz radiation can make new types of communication and detection systems true. That curved radiation can travel through corners. And that makes a new type of data communication possible. The system can transmit data between two devices directly without relay stations. Even if those devices don't have visual contact with each other.

That technology can used in communication at the bunkers. And it can make it possible to offer safe communication on the Moon over hills and around stones. On the Moon, the electromagnets can create the needed magnetic field that allows to turn those terahertz waves. 

Curved terahertz waves can revolutionize communication and detecting systems. Images show how curved terahertz waves can travel over, and around hindrances. That allows systems to communicate over hindrances straight without relay stations. 

If the system can control those rays with good accuracy, those things can used to control things like drones. How many use those interesting terahertz radiation systems depends on the accuracy. That terahertz system can control those curves. 

This type of terahertz system makes eavesdroppers harder to detect transmitters using the bearing devices. The terahertz systems that use curved terahertz waves can also used to detect things through the wall. The idea is that in that case the transmitters and detectors are not in a straight line. 

That makes it easier to hide the position of the transmitter. The curved terahertz radiation can make new types of terahertz sensors possible. What if the system can curve terahertz radiation into the donut-shaped form? In that case. The terahertz systems can return radiation to the sensor. And that can make new types of images of the targets.

These breakthroughs can make AI even more flexible.

Despite criticisms of gaming, these findings indicate potential benefits in professional fields requiring high cognitive performance, without increased cognitive fatigue.

Neuroscientists made the breakthrough when they uncovered how people learn and remember. That kind of information is required for the BCI (Brain-Computer Interface) systems that can control robots and other tools using the EEG. This kind of information is also an important thing for rehabilitating people, who have neurological damage. That data can be used to create new biological computers and microchips. 

Video games can used to simulate the new tools in the virtual world. If the person can use BCI to control some characters on screen. The same system can control interactive robots through computers.

For controlling machines, the BCI requires machine learning. The system must connect certain EEG curves with a precise right action. The AI that controls the BCI requires a dataset about those EEG curves. Those datasets are like library or dictionary books for the human brain. And without them, the BCI cannot decode thoughts. 

Video games offer a good tool for researching memory and thinking. And if a person can move characters on screen, that person can move similar things in nature. Video games improve certain types of concentration and observation. And that thing can used to teach people with concentration problems. Video games can uncover. If a person has some kind of problems with some cognitive operations. So video games can uncover, how people learn things.

Computer- or video games can be used to create virtual datasets for AI that control interplanetary missions. When AI lands probes on distant planets like Jupiter's icy moons it requires datasets that it uses. The problem with NASA is that if there is no landing mission before, there is the possibility that everything goes wrong. Flight to Jupiter takes about eight years. And if something goes wrong that mission takes 8 years for nothing. 

So the AI requires a dataset on how to control the craft. Video games are a tool that can offer practice for AI. The gamer operates virtual modules that the AI can use to create a mission profile. The AI and learning machines cannot operate using empty databases. When AI thinks it connects databases to the new entireties. The AI cannot create mission profiles without databases.

The imitation game is the method of how the researchers teach things to the AI. In an imitation game, the operator controls virtual characters. And those virtual character's actions will transfer to the physical machines. The AI-controlled robots can also imitate things that people make. The robot's actions are a series of movements or reactions. And the system can connect certain actions with certain things. 

When an imitation machine makes connections between some action and some object. That machine can create billions of connections. And then it can create a network of those action-object combinations. This type of network has unlimited capacity. And the only thing. That limits the number of action object combinations.
