Our present estimate is based on a range of agreeing models and data.
The Earth science community has, in general, moved on to new and more challenging questions.
One outstanding feature of this drama is the role played by those who themselves were not, or not exclusively, geologists.
Robert Hooke, not long after, suggested that the fossil record would form the basis for a chronology that would “far antedate ...
even the very pyramids.” The 18th century saw the spread of canal building, which led to the discovery of strata correlated over great distances, and James Hutton’s recognition that unconformities between successive layers implied that deposition had been interrupted by enormously long periods of tilt and erosion.

He was one of the dominant physicists of his time, the Age of Steam.
His achievements ran from helping formulate the laws of thermodynamics to advising on the first transatlantic telegraph cable. Shelton was a philosopher of science, critical (as shown in his contribution, the 1915 article “Sea-Salt and Geologic Time”) of loose thinking and a defender of evolution in debates.
In the 1660s Nicolas Steno formulated our modern concepts of deposition of horizontal strata.
He inferred that where the layers are not horizontal, they must have been tilted since their deposition and noted that different strata contain different kinds of fossil.
Harlow Shapley, who wrote an article in 1919 on the subject, was an astronomer, responsible for the detection of the redshift in distant nebulae and hence, indirectly, for our present concept of an expanding universe. Russell, author of the 1921 article on radioactive dating, was familiar to me for his part in developing the Hetzsprung-Russell diagram for stars, but I was surprised to discover that he was also the Russell of Russell-Saunders coupling, important in atomic structure theory. The prologue to the drama is the mid-19th century recognition of the relation between heat and other kinds of energy (see the 1857 article “Source of the Sun’s Heat”).Tags: Adult Dating, affair dating, sex dating
