millennium, the only one solved at the moment of them, and here the great merit of our scientist, grigory perelmanthe essence is who knows the poonkare hypothesis, it, well , it sounds simple, but it is very difficult to explain, any a compact three-dimensional object... can be transformed into a sphere, well, that is , you can take a glass from here and if you deform it, it will turn into a sphere, that is, there is always the possibility of turning it into a ball. this is a very serious work that will influence the understanding of the structure of the universe, the big bang theory, and many, many things, but another one of the most impressive elements that impressed me was the discovery of graphene. game, i don’t remember his name, one of the scientists was named game, the second is konstantin novoselov, these are the scientists who began their work in our chernogolovka, and more than twenty, i think years ago, they received the nobel prize in physics, they began, as i already said, in our russian institute. graphene is a substance made of pure carbon, the thinnest and strongest material. today
