In physical cosmology, the Alpher–Bethe–Gamow paper, or αβγ paper, was created by Ralph Alpher, then a physics PhD student, his advisor George Gamow, and Hans Bethe. The work, which would become the subject of Alpher's PhD dissertation, argued that the Big Bang would create hydrogen , helium and heavier elements in the correct ...
Although his name appears on the paper, Bethe had no direct part in the development of the theory, although he later worked on related topics; Gamow added his name to make the author list Alpher, Bethe, Gamow, a pun on alpha, beta, gamma (α, β, γ), the first three letters of the Greek alphabet.
Gamow was a well-known prankster, who delighted in practical jokes and humorous twists embedded in serious scientific publications. [38] [39] His most famous prank was the pioneering Alpher–Bethe–Gamow paper (1948), which was serious in its style and content.
Calculations by his student Ralph Alpher were published [6] in the famous Alpher–Bethe–Gamow paper outlined a theory of light-element production in the early universe. The first detailed calculations of the primordial isotopic abundances came in 1966 [ 7 ] [ 8 ] and have been refined over the years using updated estimates of the input ...
1948 – Ralph Alpher, Hans Bethe ("in absentia"), and George Gamow examine element synthesis in a rapidly expanding and cooling universe, and suggest that the elements were produced by rapid neutron capture. 1948 – Hermann Bondi, Thomas Gold, and Fred Hoyle propose steady state cosmologies based on the perfect cosmological principle.
He made additions to the Big Bang nucleosynthesis model that built upon the work of the classic Alpher–Bethe–Gamow paper. [2] Probably his most famous work was the astrophysical calculations that led to the Hayashi tracks of star formation, [3] and the Hayashi limit that puts a limit on star radius.
Robert Herman (August 29, 1914 – February 13, 1997) was an American astronomer, best known for his work with Ralph Alpher in 1948–50, on estimating the temperature of cosmic microwave background radiation from the Big Bang explosion. [1]
