YouTube channel MnogogrannikiRu

YouTube channel MnogogrannikiRu is a public educational channel. Our goal is to demonstrate that mathematics is not only formulas and theorems. Look at the beauty and harmony of complex mathematical solids - polyhedra. If you are interested, you will be able to collect the models of polyhedra from our collections - "Magic edges". Bright and colorful models will be the decoration of your home.


Video instructions on how to make polyhedrons from the "Magic edges" sets can be seen here!
