Beauty of sky

Lectures & Speeches



I would like to offer my popular science speakings about some astronomical topics. They have been based on self projects and knowledge. Tremendous work fred me to built my own point of view on the issues, that I covered in those lectures. My work includes the issues, that are to be raised here and has not been popularized yet. I hope, that as time flies and my knowledge is bigger I will boost you to more speakings.
