Yakov Borisovich Zel'dovich ForMemRS (Belarusian: Якаў Барысавіч Зяльдовіч, Russian: Я́ков Бори́сович Зельдо́вич; 8 March 1914 – 2 December 1987), also known as YaB, was a Russian physicist of Belarusian Jewish ethnicity, who is known for his prolific contribution in cosmology and physics of thermonuclear and hydrodynamical phenomenons.
