Space gets acquainted in different ways. Some learn about him from fiction, newspapers, radio and television programs. Thus, they are in the know and do not pretend to be more. Others want to know not only what is happening and how in space, but also why, due to what laws the phenomena proceed this way and not otherwise. Still others are not satisfied with this either. They appreciate the task for the opportunity to try their strength themselves, are in no hurry to look into the answers of the school problem book, they know how to see beauty and romance behind mean formulas.
