Ask the professionals! Natalya Golubeva works with air every day; she is a ventilation design engineer. In her book, she explains where the atmosphere on Earth came from and what it consists of, how the composition of the air affects our well-being, whether it is possible to control the weather and what carbon dioxide is needed for. This is a fascinating encyclopedia book full of amazing facts about air and those who breathe it.

For example, headphones with bone conduction of sound work on this principle.” “Wind is far from the only way to extract energy from the air. Electrical energy and even current circulate in the atmospheric layer of gases. That’s right, the atmosphere can generate energy on its own, this is called atmospheric electricity.” For whom: For those who want to broaden their horizons and improve the quality of life with the help of air.
