proposal. Several years later, in 1952, the same idea was set forth independently by an American physicist Donald Arthur Glaser. He put the idea into practice having assembled the device known now as bubble chamber. This instrument proved to be so useful in high energy physics that D. A. Glazer was awarded with the Nobel Prize in 1960. This event gave rise to Askaryan's deep concern. Of course, he was shaken that Nobel Prize was so near and, so to say, he let it slip. On the other hand, this event helped him to get faith in himself. Cosmic rays and sound waves G. Askaryan discovered and investigated in details various effects accompanying passage of high energy particles through dense matter (liquids or solids). He showed that hadron-electron-photon showers and even single fast particles may produce sound pulses. Ionization losses are quickly converted into heat, and the small region adjacent to trajectory undergoes quick thermal expansion thus generating sound waves. These results gave a new approach to the study of cosmic rays. Before, investigations of cosmic rays were based on direct interaction of cosmic ray particle with a detector. Askaryan's results made it possible to detect showers and single particles using sound receivers situated at some distance from the event. Several years ago, the registration of energetic particles and showers with sound detectors in sea water was planned as an important part of global monitoring. Cosmic rays and electromagnetic waves G. Askaryan also showed that cosmic ray showers emit electromagnetic radiation, thus giving yet another way for their detection. Before him it was commonly assumed that electron-photon showers do not emit electromagnetic radiation since the electrons and positrons are created in pairs. Askaryan's analysis led to the conclusion that in an electron-photon shower there is an excess of negative charge (excess of electrons). These excess electrons are knocked out from atoms either by photoeffect or by shower electrons and positrons (ionization). At the same time, due to the annihilation process the number of positrons decreases. Thus, there is an electric current created by the excess electrons associated with shower. This variable current is the source of electromagnetic radiation. Therefore, every shower is the source of electromagnetic radiation. These studies opened new perspectives for distant registration of cosmic ray showers. These investigations paved the way for distant registration of cosmic ray showers. Now many radio-astronomical stations are conducting observations on cosmic
