[PAR] [TLE] Ylem [SEP] Ylem is a term that was used by George Gamow, his student Ralph Alpher, and their associates in the late 1940s for a hypothetical original substance or condensed state of matter, which became subatomic particles and elements as we understand them today.  The term "ylem" was actually resuscitated (it appears in Webster's Second "the first substance from which the elements were supposed to have been formed") by Ralph Alpher. [PAR] [TLE] George Gamow [SEP] George Gamow (March 4 [O.S. February 20] 1904 August 19, 1968), born Georgiy Antonovich Gamov (Russian: Гео́ргий Анто́нович Га́мов ; ] ), was a theoretical physicist and cosmologist.  He was an early advocate and developer of Lemaître's Big Bang theory.  He discovered a theoretical explanation of alpha decay via quantum tunneling, and worked on radioactive decay of the atomic nucleus, star formation, stellar nucleosynthesis and Big Bang nucleosynthesis (which he collectively called nucleocosmogenesis), and molecular genetics.
