Obviously, the opening and amazing inventions of the scientific world are getting closer to the fairy magic.
Progress does not allow us to stand still, and makes keeping up with the times.
Let us sum up this year and find out what amazing and incredible heights modern science has made during this period.
THOUGHTS ON THE SCREEN
Who among us does not want to acquire the ability to read minds? Just imagine how it would be interesting to connect to the brain interlocutor and view his thoughts, like a movie on TV. It seems incredible, but science does not stand still.
I'm sure many have heard about the electrical signals emitted by our brains, and that sometime in the distant future they will be able to decipher. It would seem that this is possible only in the distant future. But no! Scientists were still able to beat the time.
Researchers from the University of California at Berkeley, conducted an experiment in which volunteers were to the head connected electrodes fixing activity of the brain. Then the subjects were shown a large number of video clips. After the video sequence is over, the computer scientists have downloaded data from the electrodes, and the participants viewed videos. After viewing the results of the experiment, researchers were able to link the various changes in brain activity of subjects with associated images.
Unfortunately, the "picture" was published in a diffuse form. However, when you consider that until recently digital photos also show mediocre results in the near future we can expect, and display of human thought processes.
Everyone knows that the speed of light is constant and is considered extremely high. The laws of physics do faster than light "fly" can not. This rate remains constant only vacuum, but in our environment is reduced.
Lynn Howe, a physicist from Denmark, managed to slow down to the speed of the photons even ordinary car.
In order to get a record slow the speed of light, Lin Howe decided to pass light through the cloud, which consisted of sverhholodnyh sodium atoms. The effect was similar with shooting through the water.
Lin Howe still not decided in what area you can apply this slowing of light on the practice, but he hopes that in the near future there must exist a constructor that will come up with a unique destination for discovery.
ARTIFICIAL BLACK HOLE
Scientists have long think about the mysteries of black holes in the universe. It is known that the holes have such strong gravity that getting "out of their grasp," can not even light. However, more recently the Chinese scientist Qiang Chen and Qi Yun Chu of the State Laboratory of Millimeter Waves Southeast University in Nanjing, managed to create an analogue of a black hole. This device does not have this terrible gravity, like its prototype, but the light is caught in the trap, is also not able to leave the confines of his "captivity".
To create a black hole was made by Chinese scientists sixty concentric rings of metamaterials (materials that can distort the electromagnetic waves). Then place the ring in concentric layers, choosing them so that the result is an effect similar to light enters the black hole.
According to the researchers, the artificial black hole collects solar energy much faster than solar panels and large mirrors.
Just imagine what it would be successful discovery by increasing its scale. Perhaps in the near future we will produce energy by means of artificial black holes.
Something out of nothing
The creation of matter out of nothing, is more like a magic. But scientists may argue. According to current theory, a vacuum — it is not void, but a combination of matter and antimatter particles and antiparticles. As a result of their interaction vacuum has incredible energy, which can be converted into solid matter.
To confirm this theory, researchers at Michigan State University have made antivzryv. To do this on the smallest point of the space they have concentrated very powerful laser. In the experiment, it involves several lasers, the largest of which develops power of a trillion watts. This compares with a capacity of fifteen billion ordinary light bulbs.
As a result of such an experiment in a vacuum so far managed to get a pair of electrons. Clearly, this is very small, but when you consider that this is only the beginning of research, you will soon you can expect a great "magic" discovery.
