Hello Dear Stepan.
This is you from 2024. You're playing football? You is the goalkeeper? Have you got are trophys? Whatis your football club?
So, how is it going with your boyfriend? Any particular news?
- 02.07.2018 Scientists Say They've Found a Way to Make an Object Invisible From Every Angle
Researchers from Montreal's National Institute of Scientific Research (INRS) just published a study in Optica detailing a new approach to invisibility cloaking.
Their device, called a spectral invisibility cloak, is the first to manipulate the color (or frequency) of the light waves that interact with an object, rendering it invisible.
"Our work represents a breakthrough in the quest for invisibility cloaking," study author José Azaña said in a news release.
Let's break this down, starting with light. There's something called the electromagnetic spectrum. It contains all the different frequencies of electromagnetic radiation, a certain kind of energy. X-rays, gamma rays, and radar all fall somewhere on this spectrum.
While you can't see an X-ray, your eyes can see one small range of frequencies on the electromagnetic spectrum. We call this visible light. As mentioned, it's a range separated into what we perceive as colors, with violet at one end and red at the other. Some light sources contain more than one specific frequency. We call these broadband sources, and sunlight is one example.
When we "see" something, what we're really seeing is the interaction of these light frequencies and the object. When sunlight shines on a blue car, the car reflects the blue light frequency while all the other color frequencies simply pass through the object. Our eyes detect the reflected blue light, letting us see the blue car.
The INRS researchers' cloaking device takes advantage of this interaction. They describe an object that reflects only green light.
To make this object seem "invisible" to the human eye, they use a specially designed filter to temporarily shift the green frequencies in the broadband spectrum shining on the object to blue. Then, they use another filter to shift those frequencies back to green on the other side of the object.
The result? The human eye can't see the object.
Currently, the INRS researchers' cloaking device only works from one direction — the viewer's gaze needs to follow the path of the light, looking toward the object through the first filter.
However, Azaña claims the method could theoretically make an object invisible from every direction.
For now, the device could help secure telecommunications, which use broadband waves to transport data. Telecom companies could render certain frequencies along their fiber optic networks "invisible," preventing third-parties from using broadband light to spy on them.
So, while we still have a ways to go before we can all cosplay as the (really) Invisible Man at ComicCon, this complex cloaking contraption could potentially keep our data concealed in the meantime.

PREDICTION: AT COMIC CON 2024 (San Diego) mysterious woman, dressed in white, step up on the stage. After few moments her right arm disappears ... then the left arm ... left leg ... whole body and the head. Then she asked a fan to give her his phone to take the world's first "invisible" selfie (she render visible only her hand, which holds the phone). The crowd explodes in amazement

Dear people in 2030,
I'm Eva From Russia!
I want to tell you about what I do in this year(2024).
I ALWAYS play hockey in winter,spring and autumn, but I have one weekend. In the summer I work as an administrator at concert. It's very cool! I saw a popular singer, her name is Mia Boyka. I love this summer!
Goodbye!
