Bedtime Story
Gamow settles in America and makes the most of it
Gamow after the famous Alpher-Bethe-Gamow paper went on to publish 20 more in cosmology.
He used the solutions to Einstein's field equations of both Alexander Friedmann and Georges Lemaitre describing the early universe as homogeneous (statistically), isotropic and non static.
In his papers he worked on the formation of elements via nucleosynthesis and formation of galaxies by condensation of matter.
He had initially argued that all the natural elements in the periodic table would have been synthesized right at the time of big bang (give and take few thousands of years).
Fred Hoyle, another star in the history of cosmology, disagreed.
Just like Alpher and Gamow had taken the world by storm with their radical ideas of the early universe, so did Fred Hoyle and his team of brilliant theoretical physicists and cosmologists.
Gamow later had to agree with Fred Hoyle that elements heavier than lithium could not have been synthesized early in the universe.
They would need extreme conditions provided by the thermonuclear reactions occurring in the star and later in the exploding supernovae.
In a later 1953 paper Gamow estimated the temperature of the leftover background radiation to be 7 Kelvin.
This turned out to be double that of the value that is currently agreed upon.
All the three men, Ralph Alpher, George Gamow and Robert Herman were left piqued and felt blotted out when no credit was given to them in 1965 when Penzias and Wilson made that astounding accidental discovery.
The names of the three found no mention in the 1965 papers either that of Penzias/Wilson Bell Lab team or that of Robert Dicke/Jim Peebles team of Princeton.
Gamow, like many great physicists, later turned his attention to the problem of biology; and came very close to the correct solution.
When in 1953 the double helical structure of DNA was revealed, Gamow wondered how the 4 nucleobases adenine, guanine, cytosine and thymine controlled amino acid synthesis.
He proposed that there got to some kind of code probably with 3 bases coding for one amino acid.
His idea helped Crick and later others in solving this problem of the genetic code.
In 1954, he along with Watson former a RNA Tie Club that had 20 members to correspond with the 20 amino acids.
Gamow later went on to write many popular science books of which Mr. Tompkins series went on to achieve great fame.

Girls, Genes and Gamow : By James Watson
Mr. Tompkins probably got greater fame than his creator
