Camera obscura

Camera obscura and optic cables can make the magic mirror true.

In this case, I'm writing about the surveillance system, which is working without electricity. By using the IP-cameras this kind of thing are much easier to make, but sometimes I have thought, could some people have the surveillance system, which bases the use of optic cables. In this case, the camera obscura ("pinhole camera") (1) would be equipped with the optic cable, which brings the image to the distant dark rooms? These kinds of things are fascinating, and this is the reason, why I write this kind of text.

Snow White and her mother with a magic mirror are well-known characters in the Disney story. The magic mirror tells the mother of Snow White the things, what is happening in the kingdom. Sometimes I have thought, that this kind of mirror can be the warning about the surveillance system, which tells everything to the master. But can this kind of system operate without electricity?

The camera obscura-systems are used as surveillance tools. In history, there are made small holes in the walls and paintings, that people can see, what is done in some rooms. There is one weakness in that kind of system. One sneeze can cover the entire system, and that means there must make some kind of distance between the operators and targets.

But what if we would connect the lens and the optic fiber to that system. As you see the camera obscura is the small hole on the wall, and optic fiber would allow the surveillance officer to keep little distance to the targets. And if there is the distance between surveillance operator and target, that means that the operator must not be quiet all the time.

The answer is quite interesting because the light cable or optical fibers can carry light on a very long journey if the image would be strengthened during the journey. The system would work that the optical fibers would bring the light from another room, and why not from the longer distances, and then the person who uses that kind of thing would use that optic fiber as the camera obscura.

The needed thing is the lens on both sides of the fiber. And there is needed the light, what would make the radiation in the fiber stronger, and that thing could carry the image from the long distances. The optic fibers are extremely interesting things, and even if they cannot transfer the image from kilometers, they can transport it about a couple of meters.

Optic fibers can be used in the lasers as the laser elements. They can form extremely small-size and high-accurate laser ray, which can be used in the places, where is needed very high accuracy.

The extremely small diameter lasers can be very powerful because if the optic fiber is used as the laser element by surrounding it with the led lights, that thing would be an effective tool also for the high power lasers, and if the laser element is long enough, the heat would not be a problem. By using nanotechnology, the small-size mirrors where it is a small enough hole, that can form the laser ray between those mirrors.

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...

The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like.

. The cyborg lichen can be one of the most exotic visions of what the high-tech civilization might look like. Above is the image of the nano-submarine. There is introduced an idea, that this kind of system would equip with living neurons, which makes it like some kind of artificial bug or mosquito. The idea is that the robot can take the nutrient by using the robot tube, which acts like a proboscis. The neurons can get nutrients and the rest of the machine can use small fuel cells or the energy to that system can deliver by using the radio waves. Futurologists are thinking about the ideas, what the hybridization of the neurons and machine would look like? Could the hyper-technical civilization look like the group of midget submarines? Those submarines might take nutrients for the neurons, what is living in them. The purpose of the midget submarines, which might be size less than a couple of millimeters would maximize the survivability of the neurons. One of the most intere...

Who really was Plato, the great philosopher?

When we are thinking about the great philosopher Plato, we are thinking about the man who established the Academy of Athens. And we might remember that this man was a traveler. He traveled in many places in his life and wrote many texts and books, which still is very respected thoughts about the state and other things. When we are looking at the books or series of books, we are facing the thing, that there were lots of texts. If we want to use criticism we must notice that the model of the ideal state is rising the kings in the very high position, and the thing would flatter the kings. And sometimes I have thought that maybe that famous model of the ideal state is written by somebody else. The thing is that the model, where the philosophers rule the state behind the lines of soldiers could be written for the persons like Justinian, who was really flattered. The thing is that this kind of writings was meant for flatter the rulers, who would not persecute philosophers, even they had d...
