In 1882, Popov successfully graduated from the University and was invited to stay to prepare for his professorship. Alexander dreamed of conducting experiments in the field of electricity, and this was one of the reasons that he began to teach in the officer class of Kronstadt, where there was a modernly equipped physics class. In 1890, he was invited to teach physics at a Technical school in the same city. All his free time from teaching Popov devoted to physical experiments, which resulted in the invention of radio in 1895.
In April 1895, Popov presented a new device to the Russian physico-chemical society and made a report on the invention of wireless communication. He also studied x-rays and took x-rays of various objects for the first time in Russia.

Wish we could turn back time,
To the good ol’ days,
When our momma sang us to sleep
But now we’re stressed out.

Our planet Earth is only a tiny part of the universe, but at the moment - this is the only place where we can live.People have always polluted all around. But until now pollution was not such a serious problem. People living in rural areas and did not produce such a large number of contaminants that could cause a dangerous situation on a global scale.With the development of the highly congested industrial cities that emit huge amounts of pollutants into the environment, the problem has become increasingly serious. Today, our planet is in grave danger. Acid rain, global warming, air and water pollution, overpopulation - issues that threaten human life on Earth.<span>To understand how air pollution affects our bodies, we need to know exactly what it is pollution. The pollutants, which are harmful to our respiratory system, called particulates. Particulates - a small solid particles that we see in sunlight. It is derived from incomplete combustion of fuel in engines, such as an internal combustion engine, road dust and smoke from burning wood/</span>
